BLE Road Stud Beacon ID-BLE-R09 (IP67, ER14250 Battery)

A BLE road stud beacon for smart-traffic marking

The ID-BLE-R09 puts a Bluetooth Low Energy beacon inside a yellow polycarbonate road stud. Fixed to the road surface, it broadcasts its identity continuously, so a Bluetooth receiver nearby, such as a smartphone running a beacon app or a gateway, can tell which marker it is closest to.

It sends iBeacon and Eddystone frames on the licence-exempt 2.4 GHz band (2400–2483.5 MHz) and reaches 100 m in open space. Transmit power (-40 to +4 dBm) and broadcast interval (default 500 ms) are set from the Identium Connect mobile app.

How road stud beacons are read

• Phone as the receiver: an app shows which stud or marker zone the phone is nearest to. Studs can also serve as fixed markers elsewhere, for example in parking structures.
• Gateway as the receiver: ID-BGW-02 gateways scan the studs and report over Ethernet, Wi-Fi or 4G, so the platform can confirm each marker is alive and watch its battery.

The R09 is not an AOA model; it is located by RSSI proximity, which is zone-level (around 10 m).

Battery and build

An ER14250 lithium thionyl chloride cell (2400 mAh, 3.6 V) runs it for 5 years at 0 dBm / 500 ms, and the stud is rated IP67 for -40 °C to +85 °C. No load or impact rating is published, so tell us your traffic type and surface when you ask for a quote.
