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.

PoE budget is what sizes a project, not port count. Forty-eight ports and twenty-four ports share the same 370 W.

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.

Same radios, four bodies. Coverage is decided by where the antenna can physically go.

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.

One base station, many client radios. Point to multipoint costs one radio at the centre instead of one pair per link.

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.
