Design of Indigenous 5G Network

We have build a 5G indigenous network Complete hardware and software has been designed in-house from scratch, and based on our own intellectual property. The project is funded by Department of Telecommunications (DOT), Govt. of India. This network has been instalted in IITK campus, and has been transferred to the TATA-Tejas networks and CDoT.

Network architecture of the 5G testbed

• Radio access network consisting of remote radio head, baseband unit and antennas

  • Designed at - IIT Kanpur, IIT Madras, SAMEER Chennai.

• Core network

  • Designed at CEWiT Chennai, IIT Bombay.

Remote radio head (RRH) details

• Completely designed in-house

• Can support 16,32,64 antennas

Baseband unit (BBU)

• Consists of BBU card and an off-the-shelf server

• BBU card is is designed in-house with PCIe form factor

• Communicates with RRH using optical eCPRI link

• Each BBU can support nine different sectors

  • Can support cloud radio access network architecture by communicating with other BBU cards
