Vodafone and Idea will create a new LTE ecosystem in the country on 2500MHz band (TDD-LTE on Band 41). Both companies did not have any spectrum in the 2300MHz band and they are currently offering LTE-FD on the liberalized 1800 MHz band only. Vodafone has acquired 2500MHz spectrum in 14 circles while Idea won the same in 15 circles.
While Vodafone targets metro circles and mostly cat-B circles for its upcoming LTE-TD Band 41 services, Idea skips metro circles and has concentrated on cat-B and cat-C circles.
Vodafone seems to be very serious about 4G in metro circles as they acquired 20MHz of spectrum in the band in all three metro circles – Kolkata, Mumbai, Delhi and in one cat-A circle – Maharashtra. In the remaining 10 circles Vodafone grabbed 10 MHz of spectrum in this band.
Idea along with 15 circles in 2500MHz band spectrum, has topped up in 3 circles (Maharashtra, Kerala and Madhya Pradesh) with 2300MHz band. All of these 3 circles have been enjoying Idea’s LTE-FDD on 1800MHz for some time and may eventually get LTE-Advanced by carrier aggregation across three different bands (band 3, band 40 and band 41).
Global Roll out of LTE2500:
Globally operators did not prefer 2500MHz band for LTE roll out – there are less than 20 operators who operate on this band (as per Wikipedia). China Telecom, China Mobile, China Unicom, Sprint (USA), KDDI (Japan), SoftBank (Japan), Globe (Philippines) are some of such operators, however these big operators do have another set of spectrum for majority of LTE roll out and use this band as secondary band.
Interestingly Indian operators skipped 700MHz band due to too much costly affair but LTE700 is more mature than LTE2500 and LTE700 is noted for an universal band to enable global LTE roaming. So far India has alloted 2300MHz (band 40), 1800MHz (band 3), 850MHz (band 5), 2100MHz (no commercial deployment so far), 2500MHz (band 41), 700MHz (no commercial uptake so far).
There is also a shortage of devices supporting LTE-TD on 2500 MHz band – as per GSA only 57% of all LTE devices support this band and LTE-TD as well and most of them are not smartphones. The bad news is, in India a few handsets support this band and this LTE technology. Will someone buy a new device/smartphone just to use his operator’s LTE service that is launched on a new band of spectrum?
So Vodafone and Idea will have to create the complete ecosystem around LTE-TD on 2500 MHz band including the devices from almost nothing and they will have to convince the subscribers to get a new device to start using their to-be-launched LTE 2500 MHz services. There is no way to connect to LTE2500 except via WiFi or the LTE module to support this band - and subscribers have to upgrade their smartphone on buy a WiFi Hotspot from these two operator to enjoy LTE2500.
The road is slippery for sure!
