What is 5G?
- 5G or fifth generation is the latest upgrade in the long term evolution (LTE) mobile broadband networks.
- The first generation of networks allowed only mobile voice calls to be made.
- The second generation allowed mobile voice calls as well as sending of short text messages.
- It was the third generation or 3G network which allowed web browsing on mobile devices.
- The speed and latency of which improved with fourth generation or 4G
- The 5G networks will have even faster speeds with latency down to between 1-10 milliseconds.
What has happened?
- Bharti Airtel is preparing for a 5G battle with Mukesh Ambani-led Reliance Jio.
- It has claimed its end-to-end readiness to launch the high-speed technology in the country immediately after the availability of “adequate”
- It has demonstrated live 5G services on its commercial 4G network in Hyderabad using 1800 MHz band.
- The telcos using this band rely on the existing LTE networks and will need to install a number of smaller towers to ensure adequate coverage and high-speed performance.
- The Sunil Mittal-led telco said that it can commercially launch 5G services without the mid-band with the help of existing 4G spectrum bands,
- But it will wait for the government to release 5G spectrum, especially in the mid-band.
- All 5G networks chiefly operate on three spectrum bands.
Why this hurry?
- Analysts said that Airtel is looking to position itself as the main 5G telecom operator in India.
- The announcement made by India’s second largest telco follows Mukesh Ambani’s claim that Reliance Jio will launch 5G using its own technology in the second half of 2021.
- “When we launch 5G and make it available commercially, it must have a full power of 5G instead of marketing.
- Delivering experience is a must and you need more spectrum, especially in the mid-band.
- That doesn’t mean 1800, 2300 and 2100 MHz can’t be used…true 5G will be enabled through mid-band,” “We have been working on this since last one year to make our networks 5G ready.
- It is a flick of a button.
- It is important to have the right amount of spectrum for true 5G,”
5G devices
- There are already a million 5G devices active on the telco’s network, which are broadly priced in the range of Rs 25,000.
- “Pricing will play an important role and we feel that prices need to fall between Rs 10,000-Rs 15,000 range for mass uptake.
- 4G was successful due to lower prices.
- We will work with all device partners to bring 5G smartphones to support all new and existing bands and technologies like dynamic spectrum sharing,”
- The government on Thursday took a call that permits telecom firms to make changes in technology advancements and upgrades with a notice of only six months, against one year mandated previously.
- If companies are able to secure airwaves in March, they can plan to offer 5G in six months, or around September.
- However, since the March auction is not selling spectrum in the tradional 5G bands, the 5G capabilities will be limited in terms of maximum internet speed.
- While all the companies are unanimous in demanding sale of 5G spectrum (in bands of 3,300-3,600MHz and also in 26GHz and also in 26GHz and 28GHz frequencies),
- Operators such as Jio, Airtel, regulator Trai need to be brought down price to ensure a healthy sale.
