Dispatch to driver, however far out they are
A radio stops at the edge of its coverage. A driver two states away is on the same channel as the yard, with no repeater in between and nothing to licence.
No range limit, because there is no radio
Coverage is wherever there is cellular or Wi-Fi. Adding a depot is adding people to a channel, not installing hardware on a tower.
- No tower leases, repeater maintenance or spectrum coordination
- Voice frames are small and the client tolerates loss, so it holds up on a weak connection
- A signal indicator warns the driver before they key the mic, not after
Built to be used without looking at it
The control is a ring roughly two thirds of the screen wide, because the person pressing it is driving, wearing gloves, or holding something else.
- Every state is distinguishable at arm's length — transmitting, receiving, requesting, busy
- Transmitting and receiving differ by hue and direction of travel, so they read apart without colour vision
- A hardware push-to-talk button on a rugged handset works the same as the on-screen one
The part a scanner cannot do
Fleet radio traffic is clear in the air. Anyone within range with equipment costing less than a handset can listen to your dispatch, your routes and your customer names.
- Private and company channels are locked to your own handsets; push.tt carries them without being able to listen
- Load details, addresses and customer names are not broadcast to whoever is listening
Honest limit: v1 has no forward secrecy, so a channel key that is later compromised would open past traffic captured on that channel. It is on the roadmap and it is on the security page.
Put one route on it
One dispatcher and a handful of drivers is enough to tell.
