Cambium cnPilot WiFi for Indian office: an 8 branch Pune clinic weekend
The patch cable in the Aundh branch IDF was bright pink. We don’t buy pink cables. The IT head and I keep coming back to that detail because, for the next 36 hours of the Cambium cnPilot WiFi for Indian office rollout we were about to start, every problem we found began with a piece of someone else’s history that had been left in the rack.
Saturday 8.02 AM the labelmaker came out first
The diagnostic chain runs 8 branches across Pune and one in Pimpri. Patient billing on staff Wi-Fi. Patient discharge instructions sometimes on guest Wi-Fi. Lab refrigeration sensors on a flat network that should never have been flat. The NABL audit was 11 weeks out. The clinic group’s IT head had asked for a Wi-Fi refresh that did three things. Segregate guest traffic. Move lab equipment to its own VLAN. Stop the dead spots at the back of the imaging room.
We had 22 access points to swap. Mostly D-Link DAP and TP-Link Omada from earlier owners. One Ruckus from a 2018 pilot that nobody had decommissioned. The plan was Cambium cnPilot e410 indoors, two cnPilot e510 for the rooftop link between Aundh and Pashan, and a fresh VLAN map (HPE Aruba campus wireless reference designs were our cross check on VLAN density in early 2026). I keep coming back to one thing about that morning. The labelmaker came out before the AP boxes.
What 22 APs across 8 branches actually takes
Aundh first. Three floors, six APs, two switches, one cable closet that smelled faintly hot. The smell is rarely nothing. We pulled the SFP that was running warmer than it should have been. Swapped it. The hot smell went. Arre, that one would have been the call we got at 11 PM the following Wednesday if we had not opened the door.
By lunch the Aundh APs were online. The guest VLAN had its own SSID. The lab fridge sensors were on a tagged port to their own switch. The IT head walked the floor and asked the receptionist whether the Wi-Fi felt different. She said the patient app was loading faster, which is the only metric a clinic receptionist will give you and the only one that matters. The Cisco enterprise networking guidance talks about RF density. The clinic floor talks about loading time. Both are true.

Cambium cnPilot WiFi for Indian office: Saturday afternoon to Sunday evening, branch by branch
Kothrud went clean by 3 PM. Hadapsar by 5.30. Baner by 8. We slept four hours. Sunday: Pimpri at 8 AM, Chinchwad by 11, Wakad by 1.30 PM, Viman Nagar by 4. None of the branches had the same cable map. Two had the lab refrigeration on the staff VLAN. One had an old print server still answering on a VLAN that nobody on the current IT team knew about. We documented all of it. The labels went on twice, once on the cable and once on the panel.
The one branch I would do differently in hindsight was Pimpri. Yaar, I had specced an e510 indoor for the conference room there because the IT head wanted Wi-Fi 6 throughput for video calls. The e510 was a good unit. It was also overkill for an 11 person conference room, and the e410 would have done the job at about 40 percent of the cost. The IT head pushed back on the BOM the week before. I had defended the e510. I would not defend it the same way today.
| Branch profile | AP recommended | VLAN map | Honest fit |
|---|---|---|---|
| Single floor, <15 users, no video calls | cnPilot e410 | Staff + guest + lab equipment | Default. Don’t overthink. |
| Two floors, mixed clinical + admin | 2x e410 indoor | Staff + guest + lab + IoT | Default + one for the back room. |
| Roof link or yard coverage | cnPilot e510 outdoor | Backhaul VLAN trunked | The right tool. Don’t substitute indoor. |
| Conference room with regular Teams or Zoom | e410 with channel plan review | Staff prioritised | e510 indoor is overkill for <15 seats. |

What I would change before the next 8 branch weekend
One. Walk the cable rooms before the AP order goes in. Not the floor plan, the cable rooms. The cable room is where the truth lives. The pink patch cable, the hot SFP, the print server on the orphan VLAN. None of that shows up on a site survey form.
Two. Label twice. Once on the cable, once on the panel. The branch managers will say it looks like overkill on day one. On the day someone else does a refresh in 2031, they will say it was the kindest thing IT ever did for them.
Three. Push back on your own BOM. The Pimpri e510 indoor was my call. The IT head was right to question it. The right answer was the cheaper unit. Bas, conviction is useful. Stubbornness on a BOM is not.

P.S. Naveen here. The pink patch cable is now in a Ziploc bag on my desk. The IT head asked for it. I gave it. Every site we walk, I open the cable room first. Most of the work is decided in that 20 minutes, before any AP comes out of a box. If you are 11 weeks out from an audit or a Wi-Fi refresh, open your cable room on Monday. Label everything twice.
