Description
The Nokia/NSN ESMB 472109A is a Flexi EDGE system module that delivers GSM/EDGE-specific processing and up to 18 TRX capacity within Multiradio BTS deployments. It stores and runs the GSM/EDGE BTS software, manages internal/external BTS interfaces, and supports scalable site growth by chaining or pairing with ESMC where needed. Built for field reliability, ESMB integrates alarm inputs/outputs for on-site monitoring and can be expanded via the Flexi external alarm extension unit. Typical consumption figures and –48 V DC operation make it straightforward to engineer into existing cabinets. Ideal for modernizing 2G layers or extending macro coverage, it helps operators add capacity efficiently while maintaining consistent performance across dense, multi-technology networks.
