During testing, a PC under Linux on a Core i7 processor with a frequency of 2.93 GHz successfully coped with data processing in real time.

Radio equipment: USRP N210 with SBX radio transmitter card.

Antenna: Band 7 (2600 MHz FDD), 20 MHz band.

Client equipment: Huawei E398 4G LTE USB modem (based on Qualcomm MDM9200 chipset).

During testing, the client modem recorded a speed of 60 Mbit / s for downloading, 25 Mbit / s for downloading.

A set of tools LTE Tools Fabrice Bellar ready to provide on request to interested companies. For preliminary information, there is documentation on the LTEMOD frequency generator .
