4G/5G analog base station and terminal solution

Author:Wuhan luowave Co., Ltd Click:

Project background


Using the USRP and software platform, it is possible to build 4G/5G analog base stations or terminals, and realize many functions as follows: deploy exclusive networks; use for teaching and scientific research, research base stations, terminal operating structures and protocols, etc.; develop and test products, such as replacing CMW500 Some test functions.


Scheme introduction


OpenAirInterfaceOAI


Openair interface, also known as openair interface 5g, is an open source SDR LTE project initiated and maintained by European eurecom organization. According to the 3GPP standard, OAI fully implements the core network (EPC), base station (ENB) and user (UE) of LTE protocol.

OAI overall architecture

    OAI fully implements LTE EPC, ENB and UE according to 3GPP protocol, and its overall architecture is basically the same as LTE protocol stack.

    The following is an official structure of OAI. You can see the structure diagram of ue on the left, including PHY, MAC, RLC, PDCP, RRC and NAS functions.

    In the middle is the architecture diagram of ENB, and on the right is EPC.



The following is a demo video of OAI 4G + N210:
       


Amarisoft

Amarisoft is a commercial software, the project is not open source.

Main features:

  • Implement ENB, EPC and ue of 3GPP LTE protocol completely according to the protocol
  • ENB supports LTE release 13 and UE supports LTE release 12
  • Support FDD / TDD, 1.4, 3, 5, 10, 15 and 20 MHz bandwidth
  • Hardware interface is reserved in the project, and there is no requirement for hardware (support various hardware)
  • Software optimization is good, the product can run on the notebook
  • Amari UE 100 can simulate and send data from 500 ues on a single computer

Introduction of amarisoft lte100 system

    Amarisoft lte100 is a kind of LTE base station software which can run on ordinary PC. With USRP hardware, it implements the functions of eNodeB, EPC, embms gateway and IMS. It can replace some test functions of expensive cmw500 and can also be used for private network deployment. Support LTE, LTE-A, lte-m and Nb IOT.

 


Scheme summary


   The use of USRP and OAI / amarisoft software platform can achieve 4G / 5G simulation base station and terminal construction, can flexibly realize many functions and has good expansibility.
