System User Guide
Power and Sensitivity
We.R
™
systems transmit with maximum allowed power according to standard EN 300 –440
(Europe), FCC CFR47 Part 15.
Pending the device, power and sensitivity are divided into two (2) main categories:
Sensitivity Power
-103 dBm (sensors) 14 dBm
-103 dBm (Central Control Unit) 20 dBm
Channels, Bandwidth and Polling
 Using ECOP protocol, the We.R
™
system utilizes between 1 to 16 channels.
 The channel bandwidth is 5MHz.
 The We.R
™
systems use Beacon-enabled network intervals, about 100ms for quick
response time.
 Modulation type: QPSK, 8 chips DSSS
 Baud rate: 250KBPS
Low Energy Consumption
ECOP protocol is an externally low-power RF protocol based on 16 years of experience in
battery-operated devices. For example, the system uses a mechanism that significantly
reduces listening time (one of the major drains on battery life).
2.3.3. Remote Software Update
The We.R
™
system and its components are being constantly upgraded with regards to the
software embedded into them and with regards to their service software packages.
There is no need for any user involvement in these upgrades as these are overall procedures
automatically activated by the Service Provider.
2.3.4. We.R
™
Cloud Services
The servers of the We.R
™
cloud services are the central applicative abstract unit designed for
high availability, scalability, robustness, geo-redundancy and security.
