Below is a list of hardware and software parts that make up a “standard” LimeNET basestation (BTS) 5G standalone (SA) package. For specific part parameter(s), please contact Lime Microsystems separately.
Software Defined Radio (SDR) with integrated front end – LimeNET is built on LimeSDR software-defined radio technology to deliver an app-enabled network solution covering any standard from IoT to 5G. Use of Lime’s SDR platform provides the most flexible radio hardware solution that enables numerous applications from IoT to 5G and smallcell configurations and services. It could be used to create on-demａnd network solutions where services could be easily offered for any Telco centric services. LimeNET comes pre-equipped with a flexible front-end module that provides filtering and amplification.
