2.5G BTS/4G LTE eNodeB

2.5G BTS/4G LTE eNodeB

RK Telesystem offers a dual technology BTS that works as 4G LTE eNodeB and/or 2.5G BTS, containing both the radio and baseband functions.It can be configured via software to operate as a 2.5G GSM/GPRS BTS+BSC as well as eNodeB.It has a maximum output power of 20 Watts RMS for LTE or GSM operation. It  is light weight and can be connected via satellite/any IP backhaul to deeploy anywhere anytime.

Features and benefits:

  • Software configurable as 4G LTE or 2.5G GSM/GPRS.
  • Software upgradable to future LTE and LTE-A Releases.
  • Can be used with any IP backhaul.
  • Local break-out of GPRS and LTE IP traffic for edge computing.
  • Local media routing for GSM speech calls.
  • GSM backhaul loading as little as 8 kbit/sec/call.
  • Can be powered from solar panels in most parts of the world.
  • Linux-based OS means lower management costs.
