In the EC-GSM feature, the Base Service Station (BSS) allocates special physical resources needed for extended channels to reach a Mobile Station (MS) based on a given location. Coverage classes are defined for identifying the optimal level of repetitions to the reach the MS. This coverage class value is used by the BSS to reach the MS with optimal use of resources.
With this feature, the coverage extension frequency of 20 dB, which is beyond GSM coverage, can be achieved. This indicates a seven-fold improvement in the low-rate application range. The extended coverage frequency provides the ability to reach challenging locations – deep indoors, basements, remote areas where smart meters and sensors are deployed for monitoring purposes.
EC-GSM multiplexes with existing legacy GPRS and Extended GPRS (EGPRS) traffic channels that leads in easy deployment of EC-GSM in the existing EGPRS network with a minimal impact.
EC-EGPRS is an evolution of EGPRS providing a streamlined protocol implementation, reducing device complexity while supporting energy efficient operation with extended coverage compared to GPRS/EGPRS operation. EC-GPRS is also referred as EC-GSM. EC-GPRS aims to adapt and leverage existing 2G infrastructure to provide efficient and reliable IoT connectivity over an extended GSM Coverage to enable fast time to market.
