Airtel 3G no more

Kolkata/New Delhi: The 4G network service is now available in every corner of the country. This service was introduced in the country by Jio, after which Airtel, Vodafone, Airtel and other companies started this service. This has made the 3G network redundant, as customers are no longer satisfied with the outdated technology. In view of this, Bharti Airtel has started shutting down its 3G network in Kolkata.

The company will discontinue its 3G service across the country by March 2020.

How Airtel plans to manage fresh customer queries

Gopal Vittal, CEO of Bharti Airtel (India and South Asia), said that they had started the shutdown of the 3G network in Kolkata in the June quarter. The service will be discontinued in six or seven other areas by September.

Between December and March 2020, the 3G network will be closed across the country. If further customer queries are received after the phasing out exercise, it will be seen as an upgrading request, Vittal said.

By April 2020, Airtel will have only 2G and 4G spectra.

After the 3G service closure in Kolkata, users will get high-speed 4G service equipped with the L900 technology. It is a technology where users experience the best network in crowded places, basements, markets, offices and malls.

The decision of Airtel is believed to be the fact that it has been making losses for some time in the telecom business. The company had had a net loss of Rs 2,866 crore in the first quarter of the current financial year.

Difference between 2G, 3G and 4G technology

Cellular networks or WAN are designed for citywide, national or global coverage areas and seamless mobility from one access point (often defined as a base station) to another allowing seamless coverage for very wide areas. Cellular network technologies are often split into second-generation 2G, third-generation 3G and fourth-generation 4G networks.

Originally 2G networks were voice-centric or even voice-only digital cellular systems (as opposed to the analogue 1G networks). Typical 2G standards include GSM and IS-95 with extensions via GPRS, EDGE and 1xRTT, providing Internet access to users of originally voice-centric 2G networks.

Both EDGE and 1xRTT are 3G standards, as defined by the ITU, but are usually marketed as 2.9G due to their comparatively low speeds and high delays when compared to true 3G technologies.

True 3G systems such as EV-DO, W-CDMA (including HSPA) provide combined circuit-switched and packet-switched data and voice services from the outset, usually at far better data rates than 2G networks with their extensions. All of these services can be used to provide combined mobile voice access and Internet access at remote locations.

4G networks provide even higher bitrates and many architectural improvements, which are not necessarily visible to the consumer. The current 4G systems that are deployed widely are HSPA+, WIMAX and LTE. The latter two are pure packet-based networks without traditional voice circuit capabilities. These networks provide voice services via VoIP.
