The recent approval (2021) of 5G trial is a welcome development. The local 5G technology is called 5Gi. It is being tested during the trials. The 5Gi standard has been designed to address the typical Indian rural use case. Globally, harmonised 3GPP standard is used. Qualcomm is developing a 5G solution for Reliance Jio. The addition of millimetre wave is brilliant. It is one of the key spectrum bands for 5G. It makes available large bandwidths. There is the sub-1 GHz band for trials. Open RAN (O-RAN) is a new methodology for rolling out disaggregated networks. Its architecture is more scalable and flexible. It is also more cost-effective. The telecom operators have options — use conventional networks (monolith network) along with O-RAN.
