In news: The Department of Telecommunications allowed private telcos Bharti Airtel, Reliance Jio Infocomm and Vi (formerly Vodafone Idea) and state-run telco Mahanagar Telephone Nigam Limited (MTNL) to start trials for 5G technology as well as its applications in various sectors.
About trials for 5G technology-
- 5G or fifth generation is the latest upgrade in the long-term evolution of mobile broadband networks.
- 5G mainly works in 3 bands, namely low, mid and high-frequency spectrum.
- In the initial phase, these trials will be for 6 months, including a 2 month period for procurement and setting up of the equipment.
- In these 6 months, telcos will be required to test their set up in urban areas, semi-urban areas as well as rural areas.
- During this period, the telcos will be provided with experimental spectrum in various bands, such as the mid-band of 3.2 GHz to 3.67 GHz, the millimeter wave band of 24.25 GHz to 28.5 GHz etc…
- While telcos can use and install it for commercial cellphone users who may not have specific demands for very high speed internet, the low band spectrum may not be optimal for specialised needs of the industry.
- The mid-band spectrum offers higher speeds compared to the low band, but has limitations in terms of coverage area and penetration of signals.
- The high-band spectrum offers the highest speed of all the three bands, but has extremely limited coverage and signal penetration strength.
