The M9B is able to send a beacon "Tx" and receive "Rx". In this article we explain how it works and when to use which method.

An overview of what the M9B Beacon Gateway can do can be found here: M9B Beacon Gateway - Overview

Introduction

Which method is right for you depends largely on the environment in which it is used and the objective. It is particularly important that only devices with compatible beacons (iBeacon, AltBeacon or Eddystome) are used.

Rx (Receive mode)

When you use the M9B in Rx mode, the gateway (M9B) receives incoming Bluetooth IDs that are within the reception radius of the M9B and sends them together with its own ID to the assigned DECT base.

This mode can be used for "Real Time Location", e.g. tracking objects, vehicles and people, and geofencing.

How it works (Rx)

When a Bluetooth enabled device that can send a compatible "Beacon" (e.g. handset, smartphone, BT Tag) approaches the reception radius of a Beacon Gateway M9B, it sends its Beacon (Tx) to the M9B which receives it via (Rx).
The Gateway M9B sends its ID and the ID of the Bluetooth mobile device to the base station via DECT.
The base station sends both IDs to an alarm server
The alarm server processes and stores the information and triggers messages if configured
Messages are sent to the handsets via the base station

Tx (Transmit mode)

In Tx mode we have to distinguish between two different possibilities.

The M9B is able to send a ping permanently (Tx) if this is desired.
The handsets of Snom M-Series (M70, M80, M85 and M90) which have Bluetooth LE and the appropriate beacon technology, can receive beacons permanently (Rx) but only in association with an alarm send (Tx) a location ping. Practically it works like this, that in the handset, at the moment when an alarm is triggered, a beacon gateway in the vicinity (i.e. an M9B) is searched for and if one is found, the ID of the M9B together with the alarm and the ID of the handset is sent to the assigned DECT base.

How it works (Tx)

If a Bluetooth capable device, which can send out a compatible "Beacon", e.g. a handset approaches the reception radius of a Beacon Gateway M9B, which is configured in Tx mode and sends its ID (Beacon) permanently via Bluetooth (Tx), this will be received by the handset (Rx).
The handset transmits its ID and the ID of the M9B to the assigned base station (Tx) via DECT
The base station sends both IDs to an alarm server.
The alarm server processes and stores the information and triggers messages if configured.
Messages are sent to the handsets via the base station.
