1 LimeSDR-Core SDR Board

Software defined radio (SDR) and flexible front end– LimeNET CrowdCell builds upon the ground-breaking LimeSDR software-defined radio technology to deliver an app-enabled path covering any standard from IoT to 5G. Use of Limes SDR platform provides the most flexible radio hardware solution that enables LimeNET CrowdCell to be setup in numerous varieties of small-cell configurations. Thus, it is an on-demand network solution, where services could easily shift to data, voice, IoT or any other Telco centric services. LimeNET CrowdCell comes pre-equipped with a flexible front-end module that provides signal duplexing, filtering and amplification.
