# BLE Gateway

> The anchor half of a real-time location system. Wall-mounted, wired for Wi-Fi or Ethernet, and able to raise a local alarm on its own.

## At a glance

- **100 m** BLE range, free space
- **Wi-Fi / Ethernet** Uplink, GSM optional
- **12/24 V DC** Power input
- **Relay + buzzer** Local alarm output

Either the reader or the tag can be the anchor. This is the reader-as-anchor
case: fixed infrastructure and moving beacons, with every asset tag, wristband
beacon or ColdTag within range streaming straight to it over BLE.

Wi-Fi and Ethernet are there out of the box, with GSM for a site that has no
fixed network. The dry relay and onboard buzzer turn a threshold or boundary
event into a local siren the instant it happens, and the same event reaches the
fleet dashboard. The local alarm sounds whether or not the network is up.

- [Asset Tracking](https://iotready.com/solutions/asset-tracking.md): Every asset tracking problem reduces to a reader and a tag. Which of the two is fixed is the main design decision.
- [People Tracking](https://iotready.com/solutions/wayfinding.md): Personnel tracking for factories, cleanrooms and campuses, and indoor wayfinding for the visitors walking the same building.
- [Coldchain](https://iotready.com/industries/coldchain.md): The stock record and the temperature record belong together, because a reading you cannot tie to a pallet proves nothing.
- [Heavy Manufacturing](https://iotready.com/industries/heavy-manufacturing.md): Large parts, long cycles and expensive tooling, where knowing where a thing is matters as much as knowing how many there are.
