Spectrum is for telecommunication what jet fuel is for aviation. Spectrum is a range of electromagnetic frequencies or airwaves that telecom companies use for establishing a connection between a cell tower and a mobile phone. The bandwidth of this spectrum is directly proportional to the speed of a wireless data network (since more data can be transmitted simultaneously through a broader data pipeline). In contrast, the frequency is inversely proportional to the coverage (since lower frequencies penetrate better through physical barriers and thus have wider coverage).
The spectrum holding data sheet embedded in this article represents the current spectrum holdings of all active telecom operators across all frequency bands across all 22 telecom circles along with their liberalisation status and expiry dates. All figures represented are in MHz. The value mentioned in the bracket beside the frequency at the base of each sheet is the band number where ‘B’ stands for 4G LTE band whereas ‘n’ stands for the corresponding 5G NR band.
The spectrum shown under BSNL and Aircel in white is reserved for the respective operators but has not yet been officially allotted to them.
Spectrum Liberalisation:
Spectrum was administratively allocated to operators in each of the 22 licensed service areas or circles prior to 2010, this spectrum is called non-liberalised and can only be used for 2G services whereas all airwaves allotted post-2010 have been through a Spectrum Auction where operators have paid the market discovered price and this spectrum is called liberalised and can be used for any technology platform 2G/3G/4G/5G. Alternatively, operators may choose to liberalise their administratively allotted spectrum by paying the market-discovered price to DoT on a pro-rata basis for the remaining validity of the spectrum.
Paired and Unpaired spectrum:
Spectrum may be paired or unpaired, bands 1/3/5/8/28 are all paired where one set of frequencies is used for uplink whereas another distinct set of frequencies is used for downlink known as Frequency-division duplexing (FDD), whereas bands 40/41/78/258 are unpaired where both uplink and downlink happens in the same set of frequencies separated by the time of uplink and downlink known as Time-division duplexing (TDD).
List of Indian FDD Bands:
4G LTE band | 5G NR band | Uplink frequency range (MHz) | Downlink frequency range (MHz) | Bandwidth for telecom (MHz) | Block size (MHz) |
---|---|---|---|---|---|
B1 | n1 | 1939-1979 | 2129-2169 | 40×2 | 5×2 |
B3 | n3 | 1710-1780 | 1805-1875 | 70×2 | 0.2×2 |
B5 | n5 | 824-844 | 869-889 | 20×2 | 1.25×2 |
B8 | n8 | 890-915 | 935-960 | 25×2 | 0.2×2 |
B28 | n28 | 723-733/ 738-748 | 778-788/ 793-803 | 20×2 | 5×2 |
List of Indian TDD Bands:
4G LTE band | 5G NR band | Frequency range (MHz) | Bandwidth for telecom (MHz) | Block size (MHz) |
---|---|---|---|---|
B40 | n40 | 2300-2380 | 80 | 10 |
B41 | n41 | 2535-2555/ 2615-2655 | 60 | 10 |
– | n78 | 3300-3670 | 370 | 10 |
– | n258 | 24250-27500 | 3250 | 50 |
Spectrum caps:
A spectrum cap dictates how much spectrum a particular operator can hold in a circle for a specific band. There is a 40% cap for Sub-GHz spectrum in the 700/850/900 MHz bands combined, a 40% cap for Mid-Band spectrum in the 1800/2100/2300/2500 MHz bands combined, a 40% cap for the C-Band spectrum of 3300-3670 MHz and a 40% cap for the mm-Wave spectrum bands of 24.25-27.5 GHz. The current spectrum caps are denoted in the spectrum chart.
Overall spectrum holdings of operators (in MHz):
Operator/Holding | Jio | Airtel | Vi | BSNL |
---|---|---|---|---|
Sub-GHz | 890 | 373.2 | 298.8 | 496 |
Mid Band | 1470.8 | 1964.9 | 1531.6 | 590 |
C-Band | 2440 | 2200 | 850 | 0 |
mm-Wave Band | 22000 | 17600 | 5350 | 0 |
Total | 26,800.8 | 22,138.1 | 8,030.4 | 1,086 |
Spectrum sharing/trading/leasing guidelines:
- Telecom operators holding CMTS/UASL/UL licenses can enter into a Spectrum-Sharing agreement with each other so long as both parties hold liberalised spectrum in the same band in the same circle. Sharing of spectrum is possible only on a Pan LSA level in block sizes defined by DoT and only after one year of the spectrum being acquired by an operator.
- Telecom operators holding CMTS/UASL/UL licenses can enter into a Spectrum-Trading agreement with each other so long as the spectrum being sold is liberalised. Trading of spectrum is possible only on a Pan LSA level in block sizes defined by DoT and only after two years of the spectrum being acquired by an operator.
- Telecom operators may enter into a Spectrum-Leasing agreement only with Enterprises holding a Captive Non-Public Network (CNPN) license and not with each other. The lease may be limited to any geographic area within the LSA and for any duration mutually agreed upon by both parties. A CNPN licensee can lease spectrum from multiple operators within an LSA.

@Ankit kumar Does vi offers voLTE in ranchi also do they still giving 3G services there ?
@Esmail bro: How did the spectrum in 3.5 ghz (n78) band become 370 mhz ? When did the Defence and Space ministry release the 125 mhz spectrum held by them in this band ? Also from where the additional 70 mhz spectrum came in this band ???
Happened in the last 2 months. The heads of DoT, MoD and DoS all sat together and worked out a mutually agreeable solution. DoT said it can bring in the big money by selling the spectrum to the telcos for 5G and DoS anyway has a huge amount of spectrum in band 41 for its use and the 25 MHz that it needs for its operations is limited to its ground stations which are in very few locations in the country and keeping the 25 MHz vacant across the length and breadth of the country would be a waste of a limited natural resource so Dot ensured that they will not allow the band to be deployed within a few KM radius of such ground station locations in those respective circles where the telcos get the spectrum.
As for MoD they have sufficient spectrum in most bands for their needs like 10 MHz paired to 20 MHz unpaired in most of them so leaving that 100 MHz chunk in n78 wasn’t a big deal, and it’s a big band so if they need it later the government can carve out some allotment for them from the rest of the band.
As for the fresh 70 MHz you know n78 has a total bandwidth of 500 MHz so getting the additional 70 MHz to make it 370 was not a difficult task. 130 MHz will still remain with the government in case the MoD raises a demand for it in the future.
From where you know these things ?
Partially from the news that the government puts out into the public domain and partially out of experience of tracking the telecom sector and spectrum allocations for over a decade. I know how the internal politics work in these matters. It would be cool if I had an inside connection in the Dot but I don’t 😛
