Keep the workflow. Lose the repeater.
Push-to-talk that works the way your crew already works, over the networks you already pay for — without towers, licences, or a range limit.
No range limit, no licence, no tower
Coverage is wherever there is Wi-Fi or cellular data. A driver two states away is on the same channel as the yard, with no repeater in between and nothing to licence.
- No tower leases, no repeater maintenance, no spectrum coordination
- Adding a site is adding people to a channel, not installing hardware
- Keeps working on a bad connection. Speech is sent in tiny pieces, and losing a few does not break the sentence
Your radio traffic is not private today
This is the honest reason to switch. Analogue LMR is clear in the air, and conventional DMR is trivially decoded with equipment that costs less than a handset. Anyone within range can listen.
- Private and org channels use X25519 key agreement and AES-256-GCM content encryption
- Keys are generated on the device and never sent to us
- Your organisation can hold its own escrow key, so compliance archives are readable by you and not by us
What you actually give up
A page that only lists advantages is a sales pitch, not an evaluation. Two-way radio has genuine properties we do not replicate, and you should size them before switching.
- Radio works with no network at all. push.tt needs data coverage — if your site has neither Wi-Fi nor cellular, radio is still the right answer
- Simplex radio keeps working when infrastructure fails; we depend on a server being reachable
- Battery behaviour differs: a handset running a persistent voice service draws more than a radio in standby
Most operations run both during migration. That is a reasonable end state, not a failure.
Migration without a big bang
Channels map to the talkgroups you already have. Start with one shift, keep the radios on the belt, and move the rest when the crew asks to.
- Provision users and channels centrally from the console before anyone installs anything
- Android today; iOS in development
- Rugged handsets with hardware PTT buttons work — the app treats them as a key press
Try it against your worst coverage
The useful test is not a demo in an office. Put it on two handsets, take one to the place your radios already struggle, and see which one you would rather carry.
