India has the fastest growing mobile internet base across the world and is poised to become the 2nd largest country (by user base) across the world. Indian telecom operators have increased the pace of their 4G rollouts. Earlier, mostly Airtel was launching 4G throughout the country. Currently Vodafone and Idea have stepped up their games, launching 4G in various circles. With so many operators launching/poised to launch 4G in the coming weeks and months, it’s becoming increasingly confusing as to which operator is launching 4G in which location and under which band.
There are mainly 6 different internet providers. Different operators will follow different strategies depending on their spectrum holdings. And there are primarily 4 spectrum bands on which 4G deployment is expected to take place.
- Band 5 / 850 MHz band – This band is primarily held by the yet-to-be launched operator Reliance Jio and Reliance Communications. It will provide great coverage to Reliance Jio. Reliance Communications, MTS, Tata Docomo and BSNL/MTNL are other holders of this band.
- Band 3 / 1800 MHz band – This band is already being used for 2G services in India. But this band also has the most developed device ecosystem in the world for 4G. As of now, spectrum that can be used for 4G services in this band are held by Airtel, Vodafone, Idea, Reliance Jio, Aircel, Reliance Communications, Telenor, Videocon.
- Band 40 / 2300 MHz band – This is also a popular band for 4G deployments in India. Currently Reliance Jio, Aircel, Airtel and Tikona can use this band for 4G deployments.
- Band 41 / 2500 MHz band – This band is primarily held by BSNL and MTNL. They have decided to surrender a good chunk of this band in various service areas.

If you’re looking at buying a new unlocked mobile device to use between Australian carriers, it is worth knowing which Australian networks it will support. The three mobile networks in Australia are run by Telstra, Optus and Vodafone. The various other providers all operate over these networks. Some are owned by the larger carriers, such as Virgin Mobile. Now take a view of the LTE bands used by the Aussie carriers.

What is LTE Band 12
The lower band 700Mhz is divided into five blocks as shown below in figure. The A, B, and C blocks are paired, which is LTE band 12( FDD 700Mhz Lower A/B/C) which makes them useful for services that require two-way transmission, such as wireless Internet. The upper half of the pair is usually used to transmit from a tower to mobile devices while the lower half is usually used to transmit from devices back to the network; this ordering is prevalent because higher frequency transmissions require more power.
Who use LTE Band 12
T-Mobile is the only national network in America currently utilizing band 12 LTE (regional operator US Cellular being the next largest), and support for that band is key in congested metro regions, where its low 700MHz frequency provides superior building penetration and increased capacity for the network. There are also other carriers uses the LTE band 12.
Canada: Bell (FDD 700 b mhz )
Guam: iConnect (FDD 700 b mhz), IT&E Overseas (FDD 700 a mhz)
Northern Mariana Islands: IT&E Overseas (FDD 700 a mhz)
United States: Adams Networks (FDD 700 c mhz), BIT Communications(FDD 700 c mhz), Bluegrass Cellular(FDD 700 b c mhz), CVC (FDD 700 a mhz ), Fuego Wireless (PVT), Mosaic Telecom (FDD 700 c mhz), Nex-Tech Wireless (FDD 700 c mhz), Rock Wireless (FDD 700 a mhz), T-Mobile (FDD 700 a mhz), U.S. Cellular (FDD 700 a b mhz) Continue reading “LTE Band 12 FDD 700Mhz Compatible Mobile Devices”
