Q. With reference to Radio Access Network(RAN), consider the following statements::
1.RAN uses cellular radio connections to link individual devices to other parts of a network.
2.With Open RAN, telecom players would have the flexibility to use in-house solutions or solutions from multiple vendors for RAN services.
Which of the statements given above is/are correct?

[A] 1 only

[B] 2 only

[C] Both 1 and 2

[D] Neither 1 nor 2

Answer: C
Notes:

Both the statements are correct.

RAN is a key part of a mobile network system that uses cellular radio connections to link individual devices to other parts of a network.

It comprises antennae which transmit and receive signals to and from our smartphones or other compatible devices. The signal is then digitized in the RAN-base station and connected to the network.

About Open RAN

Currently, RAN is provided as an integrated platform of both hardware and software. Therefore, it is difficult to mix vendors for the radio and baseband unit and in most cases, they come from the same supplier.

The idea of Open RAN is to change this. It aims to enable a multi-supplier RAN solution that allows for the separation – or disaggregation – between hardware and software.
