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.

@esmail what is LAA in LTE ?
Licensed-Assisted Access (LAA) is a key milestone on the road to 5G, delivering speeds of above 1 Gbps. LAA is an LTE feature that leverages the free 5 GHz unlicensed band in combination with licensed spectrum to deliver a performance boost for mobile users.
Any practical use in India.
It is useful but not for our telcos as that tech is to provide 500-600Mbps speeds over LTE using 4/5CA but our networks are not focused on providing such speeds they just want capacity and cap data speeds to 100/200Mbps max
Do you watch Ankit Kumar speedtest videos ? I have seen screenshots of above 500mbps down in Airtel
It’s Test sim with better speed cap and that results on controlled site in proper conditions not everyone can achieve that
But it means that they(Airtel) is capable of delivering such high speeds.BTW which circle do you belong to ?
They’re capable of giving such speeds in some circles and selected towers only. But 200Mbps they can give in many circles.
I’m from Chennai Circle here Airtel capable of 150Mbps only in my city
Many telcos like JIO, Airtel, Vi etc. are switching off certain bands (2300, 2100) on certain low load bts (as per their network people) from 2am to 6am claiming for power saving. This is leading to poor network coverage.
How much power appx is saved by switching off just one band (2300/2100) for just 4hrs on one tower?
Is this so called power saving policy of telcos legally allowed? Why are the Govt & regulators like TRAI, DOT not doing anything to stop this?
It is up to the telco as to what they wish to do for power saving. If they want to lower the emission power or switch off certain bands at night they cant be penalised for it. TRAI wouldn’t intervene unless they are doing a complete network blackout leaving consumers with no network at all.
I think Airtel only shuts b40 at night from when I don’t know but till 7AM.
