2 We.R RF Technology
2.1 Radio Interface Information
Our system works in a star topology where the Control Panel (gateway) acts as
the coordinator, controlling all other sensors and peripherals.
License free band disturbance
The data is sent over the air via our proprietary RF protocol (ECOP) in 802.15.4
(standard compliant in accordance with EN 300 –440) and works at 2.4 GHz ISM
band.
 Gateway (GW) uses a band pass filter for out-of-band noise suppression
 In-band noise is complaint with EN-300-440
 Inter-systems disturbance - each system uses a specific system identifier
(32bits) and filters non-conforming packets
 In case of radio jamming, the GW alerts the server of the jamming.
Power and sensitivity
 Our systems transmit with the maximum allowed power according to standard
EN 300 –440 (Europe), FCC CFR47 Part 15.
