Transport & logistics — the natural home
Fleet comms is the use case PoC was born for. Drivers spread across motorways are unreachable by any conventional system a private company could afford, while a PoC radio in every cab puts the whole fleet in one talk group with the transport office. GPS comes free with the platform — live vehicle positions on the dispatcher's screen without a separate tracking subscription — and in-vehicle mobile units with external antennas hold signal better than any handheld. Typical deployment: fixed mobile units in tractor units, handhelds for yard shunters and agency drivers, dispatch console in the office.
Construction — multi-site changes everything
A single compact site can be well served by conventional radio, and often is. The economics flip the moment a contractor runs several sites: one PoC fleet covers every site plus the head office and the directors' vehicles, with per-site talk groups and an all-sites emergency channel. Site managers stop carrying two phones and a radio. The exceptions worth respecting: deep basements and tunnelling where mobile coverage dies — those crews keep conventional sets locally, often alongside PoC for site-to-office traffic.
Security — patrols, lone workers, evidence
Mobile patrol companies were among the UK's earliest PoC adopters and it shows in the feature set: GPS breadcrumb trails for proof of attendance, lone-worker alarms with man-down detection feeding a monitoring centre, and an emergency button that overrides every conversation. Door teams covering a town's venues share one channel across the whole high street — impossible on licence-free radio, expensive on licensed. Body-worn-style PoC devices with cameras are increasingly common where evidential recording matters.
Events — deploy fast, tear down faster
Events companies love two PoC properties: zero infrastructure (no repeater to site and commission at each new venue) and instant scale (hire extra handsets for the weekend, they join the talk group the moment they power on). A festival ops team, traffic crew and medics can run structured talk groups from day one. The caveat is capacity: when 80,000 people hammer one rural mast, data can crawl — serious productions mitigate with multi-network SIMs, Wi-Fi fallback on the production compound, or a conventional backup channel for showstop calls.
Facilities, cleaning & FM — the distributed workforce
Contract cleaning and FM providers run small teams across dozens of client buildings — exactly the wrong shape for conventional radio and exactly right for PoC. Area supervisors reach any building from anywhere; lone cleaners on early shifts get check-in/check-out and alarms; clients see a professional, accountable operation. Handset budgets here are usually modest, which the value end of the market serves well.
Honest exceptions — where PoC isn't the answer
- Single-building operations with no off-site staff: conventional (even PMR446) does the job with no monthly cost.
- No-coverage environments — deep shafts, remote highlands, some marine work: direct radio-to-radio is the only dependable link.
- Comms that must survive network failure — process-safety and rescue teams: keep a conventional layer regardless of what else you deploy. The full argument is in PoC vs two-way radio.
