The 3GPP Release 9 compliant LTE UE Protocol Stack SW IP is a Category 4 UE solution. The current LTE design supports 2 transmit and 2 receiver antenna ports. There are two AD9361 Radios provisioned to support L3 relay mode operation and carrier aggregation. The L2, L3 stack is optimized for real time operation on x86 and ARM multicore platforms. It also can operate in PC based environment for non-real-time MAC-MAC testing with any e-NodeB stack. L2 and L3 software is organized as time critical and asynchronous functions. The design is flexible to partition the entire processing across ARM and DSP.
The LTE UE reference design has inter worked with multiple eNBs and T&M equipment. The UE Stack supports different form-factors for the applications like handset, Man-pack, or Outdoor type
