Field notes

Written from deployments, not datasheets

Guides on specifying networks that survive commissioning — PoE arithmetic, what Wi-Fi 7 actually changes, how to read a switch datasheet, and what to ask whoever is quoting you.

Every Lysora switch, and how to pick the right one

Thirteen switches across five families. This walks through what separates them — VLAN limits, PoE budgets, uplink speeds, temperature ratings — and gives you a way to arrive at one model rather than a shortlist.

Choosing a Lysora access point: body first, radio second

Nine access points across four form factors. The mistake is starting from the radio spec — the shape of the room decides the body, and the body narrows the list to two or three before you look at a single Mbps figure.

Wi-Fi 7 explained: what actually changed, and what it costs you

320 MHz channels, Multi-Link Operation and 4096-QAM are real improvements. Every one of them is an air-interface figure, and none of them reach a client unless the wired side was built for them.

Lysora cloud routers: sizing a gateway that does not become the bottleneck

Three gateways, from a 100-user fanless box to a rack unit rated for 1,500 clients. What the numbers mean, why concurrent sessions matter more than throughput for some sites, and how dual-WAN failover actually behaves.

Wireless bridges: when a 5 GHz link beats digging a trench

Point-to-point and point-to-multipoint explained without the marketing. What 15 dBi and a 120-degree sector actually mean on site, why TDMA matters once you add a third CPE, and the survey questions that decide whether it works.

PoE budget explained: the number that decides a camera project

Ports, watts, classes and the difference between what a switch can deliver and what it can deliver at 7pm. The arithmetic is simple; getting it wrong is not, and it is the most common reason a surveillance install goes back for a second visit.

Stop guessing the AP count: what Lysora Cloud's AI Designer does

The single most-guessed number in a wireless project is how many access points a building needs. There is a free tool inside the platform that answers it from your own floor plan, and most people never open it.

Got a site rather than a question?

Send the floor plan, the camera count or an existing BOQ and we will size it — including a free coverage heatmap.
