Warehouse network design for Wireless 3PL and Distribution Operations

Q: Why does my warehouse Wi-Fi drop scanners at the back of the aisle?

Usually one of three things. First, primary coverage at the aisle end is below -67 dBm because racking attenuation was not modeled correctly — a scanner design needs -65 to -67 dBm along the entire aisle, not just at the aisle entrance. Second, there is no secondary AP at -75 dBm or stronger for the scanner to roam to, so it stays sticky and times out. Third, 802.11r is not enabled (or the scanner firmware refuses it), so the roam that does happen takes 300+ ms and breaks the WMS session. An Ekahau-based validation walk identifies which of the three it is inside a day.

Q: Can you survey while we are running operations?

Yes. Nearly every 3PL and DC engagement we run is in an operating facility. We coordinate with your shift supervisors and inbound/outbound windows so Sidekick 2 walks happen during the lowest-impact blocks — often second-half of night shift or between inbound waves. AP-on-a-stick tripod placements move in coordination with forklift traffic. We do not shut down your operation to validate your Wi-Fi.

Q: What is the typical AP density for a 100,000 sq ft DC?

Published starting points land around 1 AP per 8,000 to 12,000 sq ft at floor level — roughly 9 to 13 APs for a 100,000 sq ft building as a rough order of magnitude. That number evaporates fast once narrow-aisle racking enters the picture, because AP-per-aisle or aisle-bisecting directional antennas are often required. Cold storage, high-bay picking modules, and dock-door coverage add APs on top. Final count comes from the Ekahau predictive model validated against Sidekick 2 walks, not a square-footage rule.

Q: Do you support Zebra and Honeywell scanner fleets?

Yes. Zebra (MC9300, TC series, VC80x forklift terminals) and Honeywell (CK65, CT45, Thor VM1A) are the two dominant handheld and forklift-mount fleets across the DCs we design. We design to the published roam thresholds in Zebra Fusion/WorryFree and Honeywell radio profiles — typically -65 to -67 dBm primary with aggressive roam triggers — and validate fast-roam behavior (802.11r FT or OKC fallback) per model before acceptance.

Q: How do cold storage APs differ from standard APs?

NEMA 4X-rated or heated APs are required for freezer and cooler environments — standard plenum-rated APs will not survive condensation cycles and sub-freezing operating temperatures. The dielectric enclosures that make these APs survive also distort antenna patterns compared to the vendor datasheet, so cold-storage predictive work must be validated onsite with Ekahau Sidekick 2 before sign-off. External antennas on pigtail are common inside blast freezers. PoE cable budgets tighten at low temperature and must be re-checked in the switch-side design.

Q: Can Wi-Fi 6E or Wi-Fi 7 improve scanner roaming?

Somewhat, but the mechanics that matter most for scanner roaming — 802.11r FT, 802.11k neighbor reports, SNR, and cell overlap — are independent of Wi-Fi generation. The real 6E and 7 wins in a warehouse are on the capacity side: 6 GHz gives you clean spectrum away from DFS and CCI issues in 5 GHz, and Wi-Fi 7 Multi-Link Operation helps with failover. Most scanner fleets in production today are Wi-Fi 5 or Wi-Fi 6 class; designing 6 GHz on top requires fleet-refresh planning.

Q: Do you survey cross-dock operations?

Yes, and cross-docks get their own sub-design because the door envelope is effectively an outdoor-indoor transition. Scanner coverage needs to hold at -65 to -67 dBm inside the trailer at the loading mouth — with the trailer doors open and with adjacent trailers in place — or inbound associates will lose WMS sessions at the dock. We validate dock coverage with AP-on-a-stick at several trailer positions and decide whether the fix is a ceiling AP inside the dock apron or a directional patch firing into the trailer mouth.

Q: How do you handle narrow-aisle racking?

Narrow-aisle and VNA racking almost always requires either AP-per-aisle placement or an aisle-bisecting directional antenna strategy. Dense metal racking attenuates 5 GHz severely aisle-to-aisle — plan for 15 to 25 dB cross-aisle loss once the racks are stocked. The predictive design uses actual rack-material attenuation values in Ekahau, and the validation walk is done aisle-by-aisle with Sidekick 2 at floor level, not at mezzanine height.

Q: What about forklift-mount scanner coverage?

Forklift-mounted terminals like the Zebra VC80x and Honeywell Thor VM1A roam at 8 mph across three to five APs per minute during active work. The RF targets are the same -65 to -67 dBm primary and -75 dBm secondary — the difference is that the forklift mast antenna places the client radio 6 to 10 feet above the floor, which changes the effective link budget compared to a handheld. We model the mast antenna gain and height in the predictive design and validate roam behavior on the moving vehicle. 802.11r FT is non-negotiable on the forklift SSID.

Q: How quickly can you mobilize to an Inland Empire site?

Our HQ sits in Valencia, which puts Ontario, Fontana, Rancho Cucamonga, and Moreno Valley inside a routine drive. We routinely start onsite AP-on-a-stick work within the same week of SOW signature for IE, LA, Orange County, and Long Beach/Carson facilities. Agricultural cold-chain work in the Bakersfield corridor and distribution in the Antelope Valley are within the same same-week window. Further-out corridors — Central Valley, San Diego — are typically 1 to 2 weeks depending on operator access coordination.

Warehouse network design is not office wireless with more square footage. It is a different engineering problem. A production warehouse wireless network carries forklift-mounted scanners roaming at 8 mph, narrow-aisle racking loaded with liquid-laden SKUs, dock-door thermal gradients, and Warehouse Management System sessions that drop on a single 120 ms roam — any one of them can break a design that worked beautifully in the front office.

Warehouse network design — Ekahau data-rate and throughput heatmap across narrow-aisle racking, dock doors, and cold storage, validated with Sidekick 2

We design warehouse, 3PL, and distribution center wireless to hold -65 to -67 dBm along every aisle and dock, 25 dB SNR throughout, and sub-50 ms 802.11r roams across the Zebra and Honeywell handhelds you already own. Our bench has 25 years in enterprise networking, holds Ekahau ECSE certification, and runs a multi-CCIE bench. We are minority-owned and work vendor-agnostic across Cisco Catalyst 9800, Meraki, Aruba Central, Juniper Mist, Ruckus, and Extreme. Every engagement closes on a fixed-fee SOW. Start with the wireless services hub or skip to project intake.

Why Warehouse network design is harder than office Wi-Fi

Office Wi-Fi serves laptops and phones with forgiving roam behavior, tolerant TCP stacks, and users who restart the app when it hiccups. Warehouse network design has no such tolerance: a 3PL wireless design serves a fleet of Zebra MC9300s, Honeywell CK65s, forklift-mounted VC80x terminals, voice-pick headsets, and Cognex fixed scanners talking to a WMS over session-state-sensitive telnet emulation or SAP GUI.

A single roam longer than 100 ms drops that session, and the driver is now sitting in front of a frozen terminal at the end of a 40-foot aisle while the conveyor keeps moving. WMS wireless reliability — measured as uninterrupted session persistence across roams — is the first-order design target of any serious warehouse network design, not coverage.

Dense racking at 5 GHz attenuates far more aggressively than drywall and cubicle fabric. A pallet of bottled liquid in aisle 17 absorbs signal roughly the way a swimming pool does. Cross-aisle propagation is frequently 15 to 25 dB worse than open-space free-space loss, which is why the “one AP every 12,000 sq ft” rule from a conference room plan fails on the floor.

Seasonal flux makes it worse: a DC that measured clean in April can miss coverage at -72 dBm in November after peak stocking fills the upper racks. Cold storage adds NEMA-rated enclosures, heating elements, condensation, and dielectric materials that distort antenna patterns. These are the reasons a generic office integrator ships a warehouse survey that fails acceptance testing on day one — and why serious warehouse network design starts with a dedicated warehouse RF engineer.

We treat the warehouse as a capacity-plus-roaming problem from the first call. Read how we run Ekahau site surveys and why Wi-Fi 7 deployment changes the math on the floor.

RF Targets for Zebra Scanner Wi-Fi and Voice Fleets

A warehouse Ekahau survey produces published, defensible numbers. These are the targets we design a warehouse wireless network to, and validate against with Ekahau Sidekick 2. Zebra scanner Wi-Fi roam thresholds and Honeywell scanner roaming profiles sit on top of them — the RF floor below is what makes their aggressive roam configs work in production.

Primary coverage (data, scanners): -65 to -67 dBm RSSI along every aisle, dock, staging lane, pick module, and cross-dock door.
SNR: 25 dB minimum, 30 dB preferred for sustained MCS rates on forklift-mounted terminals.
Secondary AP RSSI: -75 dBm or stronger from a second AP at every measurement point so fast roaming has a target.
Cell overlap: 20 to 25% at the -67 dBm contour — standard voice-grade overlap — so any scanner sees two APs at -67 dBm everywhere it goes.
Co-channel interference: serving AP at least 19 dB stronger than the next co-channel AP, or the weaker AP at -85 dBm absolute.
Airtime utilization: design to 30% channel utilization per BSS, investigate at 50%, remediate before 70%.
Roaming: 802.11r FT enabled (or OKC where legacy scanners refuse FT), with 802.11k neighbor reports for pre-roam candidate selection.
Roam time budget: under 50 ms end-to-end; single roam events longer than 100 ms drop SAP GUI and telnet-emulation WMS sessions.

Vendor scanner fleets each have their own published behavior. The table below captures the profile settings we set against in a Zebra- or Honeywell-heavy facility.

Scanner-fleet RF targets by vendor
Fleet	Min RSSI design target	Roam profile	Fast-roam support	Notes
Zebra MC9300 / TC series / VC80x	-65 to -67 dBm	Fusion / WorryFree “aggressive”; roam trigger typically configurable -70 to -65 dBm	802.11r FT; OKC for legacy	Forklift-mount VC80x needs 5 GHz priority; PSK and 802.1X both production-tested.
Honeywell CK65 / CT45 / Thor VM1A	-67 dBm	Honeywell roam thresholds configurable per radio profile	802.11r FT; OKC	Thor VM1A (forklift) benefits from external antennas; directional mast patterns change the predictive model.
Voice-pick headsets (Vocollect / Honeywell A700x)	-65 dBm	WMM-PS mandatory; voice-grade roam < 50 ms	802.11r FT required	Legacy A500 fleets may still demand OKC; validate before pushing FT enterprise-wide.
Cognex fixed scanners (dock / conveyor)	-65 dBm at fixed mount	Static association; no roam expected	N/A	Treat as infrastructure; dedicated SSID + wired-preferred where run feasible.
Apple / Android BYOD supervisor devices	-67 dBm	iOS begins scan near -70 dBm and roams on ≥ 8 dB differential	802.11r FT	Do not tune the scanner fleet to BYOD behavior — they have different thresholds.

Dock doors get special attention. A scanner in the yard or inside a parked trailer sits in a Faraday-like environment; we run APoS validations with trailer doors open and closed to understand the real coverage envelope at the loading mouth, then decide whether a dock-door AP or a directional patch from inside is the right answer.

Racking RF Design and Inventory Flux

Racking RF design is the single most common reason a 3PL wireless design that passed predictive modeling fails in production. Dense steel racking at 5 GHz attenuates severely aisle-to-aisle, which is why AP-per-aisle — or an aisle-bisecting directional antenna strategy — is the default in narrow-aisle pick modules. A floorplan that looks like one AP can cover three aisles at 5 GHz is almost always a floorplan whose racking RF design has not accounted for -72 to -80 dBm cross-aisle loss once the racks are full.

We handle it two ways:

AP-per-aisle with omni or low-gain patch, mounted at rack top or ceiling centered on the aisle — typical for narrow-aisle VNA and man-up operations.
Aisle-bisecting directional antennas — a single AP at one end of the aisle with a narrow-beam patch firing down the aisle — efficient in very long aisles with predictable rack heights.

Seasonal stocking changes RF. A DC surveyed empty in Q1 and stocked to ceiling in Q4 can shift coverage contours by 5 to 10 dB in affected corridors. We plan for it by designing to worst-case-stocked conditions, not the empty-building predictive. Post-install validation is scheduled around the realistic stocking state, not whenever the engineer is available. A predictive-then-validated survey catches these failures before the customer does.

Cold Storage Wi-Fi and Harsh Environments

Cold storage Wi-Fi is a different build entirely. Freezers at -10 to -20 °F, coolers at 34 to 38 °F, and rapid thermal transitions at the door mean standard plenum-rated APs fail within months. The cold storage Wi-Fi design pattern we use:

NEMA 4X-rated or heated APs (Cisco IW-class, Aruba outdoor ruggedized, or vendor-equivalent) for any space below 0 °C or with active condensation.
Dielectric enclosure effects — plastic and composite housings distort antenna patterns in ways the vendor datasheet rarely captures fully — so we always validate with Sidekick 2 after install. Predictive alone is insufficient.
External antennas on pigtail, mounted through the panel with proper gasketing, are frequently the cleanest answer inside blast freezers and rapid-chill rooms.
Cable runs rated for cold; PoE budgets re-checked because cable resistance rises at low temperature.
Dedicated SSID + VLAN segmentation so cold-storage scanner traffic is engineered separately from ambient DC.

Dust, humidity, and diesel particulate in outdoor yards and cross-dock aprons demand the same IP-rated treatment. We coordinate AP selection with the BOM so the operator is not paying for outdoor hardening they do not need, and is not stuck with consumer-grade APs where they do.

Honeywell Scanner Roaming and WMS Session Persistence

Honeywell scanner roaming and Zebra scanner Wi-Fi roam behavior drive every forklift and handheld session that matters on the floor. A forklift-mounted Wi-Fi session associating through a cross-dock at 8 mph touches three to five APs per minute, and every one of those roams has to complete inside 50 ms or WMS wireless reliability collapses. The protocols that make this work:

802.11r Fast BSS Transition (FT): pre-computes PMK-R1 keys so the re-authentication skips the full 802.1X handshake. Typical 802.11r FT roam: 10 to 50 ms. Full 802.1X with no FT: 200 to 800 ms, which is the failure mode operators report as “scanners just drop at the back of aisle 12.”
802.11k neighbor reports: the AP hands the client a list of candidate neighbor APs so the client skips a full off-channel scan. Zebra Fusion and Honeywell drivers honor this; it shaves the scan portion of the roam materially.
802.11v BSS Transition Management: the controller can nudge sticky clients to a better AP. Client behavior varies; treat as hint, not mandate.
OKC fallback: for legacy scanner OS images or firmware levels that refuse 802.11r association, OKC provides a pre-FT PMK cache that still accelerates roaming meaningfully. We test both on APoS and choose per-fleet.

The interop reality is that some legacy Zebra and Honeywell images fail to associate when 802.11r is enabled on the SSID. Adaptive FT, or a separate legacy SSID bridged on the same VLAN, is the standard mitigation. We validate before flipping it enterprise-wide. The same reasoning applies to voice-pick fleets: Vocollect and Honeywell headset profiles want WMM-PS, voice-grade overlap (20 to 25% at -67 dBm), and FT mandatory.

Ceiling Height and Antenna Strategy

Clear-height ceilings above 30 feet are routine in distribution centers, and they change every part of the warehouse network design. Mounting an omni AP at 36 feet and expecting it to hold -65 dBm at floor level across 120 feet of aisle is a predictive design failure. The antenna math is mechanical: signal strength drops roughly 6 dB per doubling of distance in free-space terms, plus every dB of rack, pallet, and liquid attenuation between AP and scanner. At 36 feet clear-height the AP-to-floor slant angle through a loaded rack can account for 15 dB of loss before the scanner ever sees the beam.

The standard fix in very-high-ceiling DCs is a directional or patch antenna — typically 8 to 13 dBi with a narrow vertical beamwidth — mounted aisle-center with sector pointed down. Downtilt math matters: a 30-degree vertical beamwidth patch at 36 feet with 10 degrees of mechanical downtilt illuminates a usable footprint of roughly 60 to 90 feet along the aisle at floor level. We model it in Ekahau Pro with the actual antenna pattern files and validate with APoS before committing the BOM.

Forklift-mounted Wi-Fi on Zebra VC80x and Honeywell Thor terminals almost always takes external antennas on the mast; we factor that mast gain and mounting height into the warehouse network design so the vehicle antenna meets the AP halfway.

Inland Empire and SoCal logistics corridor

The Inland Empire logistics corridor — Ontario, Fontana, Rancho Cucamonga, Jurupa Valley, Moreno Valley, Redlands, San Bernardino, Perris, Beaumont — is the densest 3PL footprint in the western United States. Our SoCal base means we can walk a 1.2M sq ft DC in Ontario or Fontana the same week the client signs, not the month after. Our Inland Empire wireless engineering page covers the corridor in detail.

We work the full corridor and the adjacent distribution footprints:

Port-adjacent fulfillment in Long Beach, Carson, Wilmington, and Harbor Gateway — covered from our Los Angeles wireless and Orange County wireless pages.
North LA County distribution in Santa Clarita, Valencia, Castaic, and the Santa Clarita corridor — our HQ is in Valencia, so drive time from office to dock door is minutes.
High-desert distribution in Palmdale, Lancaster, and the Antelope Valley — including temperature-extreme operations where AP selection matters.
Agricultural cold-chain in the Bakersfield corridor and Central Valley — produce cooling, grower-shipper pack houses, and export prep.
South-border cross-dock and San Diego wireless facilities serving the Otay Mesa/Tijuana manufacturing corridor.

We have delivered warehouse network design and validation for a national discount retail chain distribution network, a national pet retail chain DC-plus-store rollout, a 3PL logistics provider, and cold-chain fulfillment operators. We reference customers by category only — never by name — because our public-sector and enterprise clients expect that discretion and because supplier-diversity procurement programs depend on it.

Our Warehouse Ekahau Survey and Engagement Methodology

Every warehouse Ekahau survey we run follows the same methodology, sized to the building:

Discovery and fleet inventory. Scanner models, firmware, WMS platform, dock count, racking style, seasonal flux, cold-storage scope, and operating-window constraints. This is where the right technical questions get asked.
Ekahau predictive design. We import the floorplan, build wall and rack materials, place APs and antennas with the actual vendor models from the chosen platform, and simulate for -65 to -67 dBm primary, -75 dBm secondary, 25 dB SNR, and 20 to 25% overlap at the -67 dBm contour.
AP-on-a-stick validation in operating facilities. We coordinate with your inbound/outbound windows so APoS work lands in low-traffic blocks. Sidekick 2 runs concurrent 2.4, 5, and 6 GHz scans with integrated spectrum capture. Cold-storage zones, narrow-aisle pick modules, and dock-door envelopes get priority.
Final design, BOM, and drawings. AP count, mount locations, antenna types, cable runs, PoE budget (802.3bt for Wi-Fi 6E/7 APs), switch-side mGig requirements, and as-built AutoCAD.
Post-install validation. Walk every aisle, dock, and cold-storage space. Heatmaps for RSSI, SNR, data rate, channel, and secondary coverage. Roaming decision logs on a sample of the scanner fleet. Sign-off against the SOW’s acceptance criteria.
Fixed-fee SOW. No hourly creep. The SOW names the deliverables and the acceptance criteria up front.

Warehouse Wireless Network FAQ

Why does my warehouse Wi-Fi drop scanners at the back of the aisle?

Usually one of three things. First, primary coverage at the aisle end is below -67 dBm because racking attenuation was not modeled correctly — a scanner design needs -65 to -67 dBm along the entire aisle, not just at the aisle entrance. Second, there is no secondary AP at -75 dBm or stronger for the scanner to roam to, so it stays sticky and times out. Third, 802.11r is not enabled (or the scanner firmware refuses it), so the roam that does happen takes 300+ ms and breaks the WMS session. An Ekahau-based validation walk identifies which of the three it is inside a day.

Can you survey while we are running operations?

Yes. Nearly every 3PL and DC engagement we run is in an operating facility. We coordinate with your shift supervisors and inbound/outbound windows so Sidekick 2 walks happen during the lowest-impact blocks — often second-half of night shift or between inbound waves. AP-on-a-stick tripod placements move in coordination with forklift traffic. We do not shut down your operation to validate your Wi-Fi.

What is the typical AP density for a 100,000 sq ft DC?

Published starting points land around 1 AP per 8,000 to 12,000 sq ft at floor level — so call it roughly 9 to 13 APs for a 100,000 sq ft building as a rough order of magnitude. That number evaporates fast once narrow-aisle racking enters the picture, because AP-per-aisle or aisle-bisecting directional antennas are often required. Cold storage, high-bay picking modules, and dock-door coverage add APs on top. We do not ship a design from a square-footage rule of thumb — final count comes from the predictive model validated against Sidekick 2 walks.

Do you support Zebra and Honeywell scanner fleets?

Yes. Zebra (MC9300, TC series, VC80x forklift terminals) and Honeywell (CK65, CT45, Thor VM1A) are the two dominant handheld and forklift-mount fleets across the DCs we design. We design to the published roam thresholds in Zebra Fusion/WorryFree and Honeywell radio profiles — typically -65 to -67 dBm primary with aggressive roam triggers — and validate fast-roam behavior (802.11r FT or OKC fallback) per model before acceptance. We are vendor-agnostic on the infrastructure side, but the scanner fleet drives the RF targets either way.

How do cold storage APs differ from standard APs?

NEMA 4X-rated or heated APs are required for freezer and cooler environments — standard plenum-rated APs will not survive condensation cycles and sub-freezing operating temperatures. The dielectric enclosures that make these APs survive also distort antenna patterns compared to the vendor datasheet, so cold-storage predictive work must be validated onsite with Ekahau Sidekick 2 before sign-off. External antennas on pigtail are common inside blast freezers where the electronics live outside the cold envelope. PoE cable budgets tighten at low temperature, which also affects the switch-side plan.

Can Wi-Fi 6E or Wi-Fi 7 improve scanner roaming?

Somewhat, but the mechanics that matter most for scanner roaming — 802.11r FT, 802.11k neighbor reports, SNR, and cell overlap — are independent of Wi-Fi generation. The real 6E and 7 wins in a warehouse are on the capacity side: 6 GHz gives you clean spectrum away from the DFS and CCI issues in 5 GHz, and Wi-Fi 7 Multi-Link Operation helps with failover. Most scanner fleets in production today are Wi-Fi 5 or Wi-Fi 6 class; designing 6 GHz on top of that requires fleet-refresh planning. Our Wi-Fi 7 deployment page covers the migration math.

Do you survey cross-dock operations?

Yes, and cross-docks get their own sub-design because the door envelope is effectively an outdoor-indoor transition. Scanner coverage needs to hold at -65 to -67 dBm inside the trailer at the loading mouth — with the trailer doors open and with adjacent trailers in place — or your inbound associates will lose WMS sessions at the dock. We validate dock coverage with APoS at several trailer positions and decide whether the fix is a ceiling AP inside the dock apron or a directional patch firing into the trailer mouth.

How do you handle narrow-aisle racking?

Narrow-aisle and VNA (very narrow aisle) racking almost always requires either AP-per-aisle placement or an aisle-bisecting directional antenna strategy. Dense metal racking attenuates 5 GHz severely aisle-to-aisle — plan for 15 to 25 dB cross-aisle loss once the racks are stocked. The predictive design uses actual rack-material attenuation values in Ekahau, and the validation walk is done aisle-by-aisle with Sidekick 2 at floor level, not at mezzanine height where the signal is artificially strong.

What about forklift-mount scanner coverage?

Forklift-mounted terminals like the Zebra VC80x and Honeywell Thor VM1A roam at 8 mph across three to five APs per minute during active work. The RF targets are the same -65 to -67 dBm primary and -75 dBm secondary — the difference is that the forklift mast antenna places the client radio 6 to 10 feet above the floor, which changes the effective link budget compared to a handheld. We model the mast antenna gain and height in the predictive design and validate roam behavior on the moving vehicle, not just at stationary test points. 802.11r FT is non-negotiable on the forklift SSID.

How quickly can you mobilize to an Inland Empire site?

Our HQ sits in Valencia, which puts Ontario, Fontana, Rancho Cucamonga, and Moreno Valley inside a routine drive from the office. We routinely start onsite APoS work within the same week of SOW signature for IE, LA, Orange County, and Long Beach/Carson facilities. Agricultural cold-chain work in the Bakersfield corridor and distribution in the Antelope Valley are within the same same-week window. Further-out corridors — Central Valley, San Diego — are typically 1 to 2 weeks depending on operator access coordination. See our Inland Empire, Los Angeles, and Bakersfield pages for regional detail.

Warehouse network design: what every engagement includes

Every warehouse network design engagement we deliver covers the same seven categories, mapped to a fixed-fee SOW before work starts. Warehouse network design is not a survey report — it is an end-to-end commitment from RF design through validated handoff.

Pre-design discovery. We walk the floor, photograph the rack topology, and build a warehouse network design brief that lists every scanner model, every WMS host, every 802.1X supplicant, and every cold storage zone. This grounds the warehouse network design in reality instead of a floorplan PDF.
Ekahau predictive model. Scaled to the actual racking density with liquid-loaded pallet attenuation modeled in. Warehouse network design that skips predictive and jumps to AP-on-a-stick routinely underbuilds the 5 GHz side.
Onsite AP-on-a-stick validation. Sidekick 2 measurements at every aisle, every dock door, and every cold storage cutover. Warehouse network design is the only discipline where a predictive model without onsite validation is malpractice.
BOM and cable plan. We deliver a vendor-agnostic BOM — Cisco 9800, Meraki, Aruba Central, Juniper Mist, Ruckus, or Extreme — plus a structured-cabling pull list with ceiling-height and antenna-type specifications per AP.
Deployment supervision. Senior engineer on site for the first shift of cutover, with a WMS roaming rehearsal and a 24-hour soak before sign-off. The warehouse network design is not complete until it survives a peak-hour shift.
Validation test report. A second Sidekick 2 pass after deployment, benchmarked against the original warehouse network design targets for coverage, SNR, roam latency, and WMS session persistence.
Day-90 re-survey. Optional. A follow-up survey once seasonal inventory flux and forklift traffic have shaped real-world conditions, with a warehouse network design delta report and any recommended antenna or channel adjustments.

The reason our warehouse network design engagements close on fixed fee is that the scope is this specific up front. If the scope changes — a new mezzanine, a new cold-storage addition, a new WMS migration — we issue a change order against the warehouse network design, not an hourly reopening.

Warehouse network design sector coverage

Our warehouse network design practice covers 3PL, retail DC, cold-chain, and manufacturing sites. Every warehouse network design engagement is scoped to the rack topology and the handset fleet — a warehouse network design for a 3PL is not a warehouse network design for a cold-storage site, and neither is a warehouse network design for a pick-to-light flow facility. A warehouse network design for an e-commerce pure-play reads different again.

A good warehouse network design documents the scanner fleet, a good warehouse network design documents the WMS roam profile, a good warehouse network design documents the dock-door thermal gradient, and a good warehouse network design documents the cold-storage dielectric loss. A generic coverage map is not a warehouse network design. A predictive-only model is not a warehouse network design. A validation-only survey is not a warehouse network design. A fixed-fee warehouse network design combines all three, signed off by a multi-CCIE warehouse network design lead, and every warehouse network design we ship is Ekahau-based.

Warehouse network design has to survive environments that punish RF — forklift-mounted radios, cold-storage condensation, rack-to-rack reflection. WiFi Hotshots approaches warehouse network design, warehouse wireless network design, and 3PL wireless network builds the way the Wi-Fi Alliance approaches harsh-environment certification: measured, repeated, and documented.
