The Department of Telecommunications (DoT) is set to begin consolidating 1800MHz airwaves in seven circles in a bid to establish contiguous blocks of spectrum, suitable for LTE use, the Economic Times writes, citing two people aware of the matter. The seven circles reportedly earmarked for the harmonisation process are Delhi, Kolkata, Madhya Pradesh, West Bengal, North East, Uttar Pradesh East and Uttar Pradesh West. The 1800MHz band in the aforementioned circles is expected to be harmonised before the next spectrum auction in 2016, whilst the same process is expected to be gradually rolled across the following circles afterwards: Assam, Maharashtra, Bihar, Odisha, Tamil Nadu, Andhra Pradesh, Gujarat, Rajasthan, Haryana and Mumbai. By reorganising the band into contiguous blocks large enough for 4G services, the DoT will boost the value of the airwaves, allowing the regulator to increase the reserve price, one of the sources noted, adding that the watchdog is also expecting to free up an additional 10MHz of spectrum for 4G use.
