2.3. Unique Technologies Incorporated
The We.R
™
system incorporates some unique technologies and features:
2.3.1. Enhanced Controlled Open Protocol
The We.R
™
products intercommunicate with the Central Control Unit (CCU) within the HAN
(Home Area Network) using Essence proprietary Enhanced Controlled Open Protocol (ECOP)
protocol. The We.R
™
CCU serves as the gateway between the HAN and the GSM/GPRS or
Internet network.
 Between home sensors and home control units (ECOP-R).
 For external networks (control unit to the world).
 ECOP-X – The XML representation of the ECOP protocol.
Several types of clients (Web Server, iPhone, Windows Mobile, etc.) parse the ECOP protocol.
The ECOP-N protocol is serialized to a standard XML and is transferred to any kind of client (a
distinct ECOP-N protocol parser is not needed for each kind of client).
For details of the RF implementation of the ECOP protocol, please refer to paragraph 2.3.2.
below.
2.3.2. We.R
™
RF Technology
2.3.2.1. Radio Interface Information
The We.R
™
system works in a star topology where the Central Control Unit acts as the
coordinator, controlling all other sensors and peripherals.
License-free Band Disturbance
Data is sent over the air utilizing the We.R
™
proprietary RF protocol (ECOP) in IEEE 802.15.4
standard based on the 2.4 GHz ISM band.
 Gateway (GW) uses a band pass filter for out-of-band noise suppression.
 In-band noise is compliant with EN-300-440.
 Inter-systems disturbance – each system uses a specific, 32bits, system identifier and
filters non-conforming packets.
