Backhaul spectrum clash: Telcos face off against tech giants over India's internet backbone
Every time we make a video call, stream a movie, or send a message, there's a lot happening behind the scenes to keep us connected. One important part of this process is something most people don't hear much about—backhaul spectrum, the new battleground between telecom operators and technology companies such as Meta, Google, Amazon. A rift is also brewing among telcos on India's spectrum allocation method for backhaul services. Backhaul is the link that connects mobile towers and Wi-Fi points to the main internet network, helping data travel between devices and the wider web. As the government looks to decide how the backhaul spectrum should be allocated, telcos and tech firms have presented sharply different views. Telecom operators want all such spectrum to be reserved for them owing to growing data traffic on their networks. Technology companies, represented by the Broadband India Forum, are calling for allocation of spectrum to other entities as well, and in some cases, for licence-free use of certain bands to support wider internet access and innovation. 'We are of the view that the demand for these traditional microwave bands will persist due to rapid urbanization and densification requirements (and) increased cellular traffic from 5G and future network technologies. Therefore, the existing spectrum in traditional microwave backhaul bands should be made fully available to TSPs (telecom service providers)," said S.P. Kochhar, director general of the Cellular Operators Association of India, in a submission to the Telecom Regulatory Authority of India (Trai) on 2 July. The issue of backhaul spectrum is important for India, where patchy fiber connectivity makes wireless backhaul crucial for expanding 5G, rural broadband, and public Wi-Fi networks. However, a lack of clear policy on how backhaul spectrum will be allocated— whether through auction, administrative assignment, or delicensing—has created uncertainty for both telecom operators and tech companies. Tech companies for a non-auction route For backhaul purposes, the telecom operators have been assigned provisional spectrum in bands such as 6 GHz and 21 GHz, as well as in E (71-76 GHz, and 81-86 GHz) and V bands (57-64/ 66 GHz). In areas where laying fiber is difficult or delayed, backhaul using E and V bands is critical for supporting 5G and high-speed internet as these bands can wirelessly carry large volumes of data between towers. According to the department of telecommunications, only 46.09% of the towers in Indiawere connected to the core network using optical fibre cables(called tower fiberization), as of March, underscoring the need for backhaul spectrum to meet higher traffic demand on telecom networks. 'Some of these traditional/legacy spectrum bands are now being used and some more are likely to be used for other mobile/Wi-Fi/satellite services. Hence it may be required not only by TSPs but also for other entities, viz. Satcom Service Providers, Wi-Fi service providers, research institutions and academia for fuelling innovation," the Broadband India Forum told Trai in a recent communication, advocating for a non-auction route for allocating spectrum. The technology companies forum's and the cellular operators association's submissions to Trai were in response toa consultation on the assignment of the microwave spectrum. The forum also argued for licence-free use of 9 GHz spectrum in the lower V band (57-66GHz) to support contactless ports, device-to-device data transfer, and motion-sensing. 'V-band is already allowed on license-exempt basis world-wide except for a few countries. If V-band continues to be restricted and licensed, innovative new technologies and products would be unable to see the light of the day and consumers in the Indian market would be deprived of the latest and innovative solutions," it said. The technology forum added that new technology such as WiGig, which allows wireless data transfer at multi-gigabit speeds, faster than regular Wi-Fi, requires such a band. Airtel vs Jio on spectrum allocation Although telecom operators are on the same page on backhaul spectrum, Reliance Jio and Bharti Airtel are at loggerheads over the method for allocation of spectrum. Jio is against allocating backhaul spectrum without holding an auction, citing national security concerns from non-telco entities. Airtel, echoing the views of other technology companies, has called for a non-auction method for spectrum allocation. As per Schedule 1 of the Telecommunications Act 2023, backhaul spectrum is among items for which spectrum is to be assigned administratively (the non-auction route). 'The current administrative assignment methodology of temporary assignments at a high percentage of AGR (adjusted gross revenue) as spectrum charge has not worked and a large amount of spectrum remains idle with the government, while the TSPs have shortage of backhaul capacities," Jio told Trai in a submissionon 2 July. 'Unlicensed access to spectrum usable for IMT (international mobile telecommunication) services distorts the level playing field and impacts the investments in the sector, besides being technically ineffective," Jio added. Airtel said subjecting these bands to auction-based allocation would not jeopardize service continuity due to non-availability of required backhaul spectrum and could create an artificial scarcity by provisioning more spectrum towards access services. 'It is pertinent to note that the operators with limited fiber infrastructure are especially dependent on wireless backhaul, and exposing these critical resources to auction dynamics for varied purposes would create severe competitive imbalances," Airtel told Trai on2 July. A call for pricing reforms Both Jio and Airtel, as well as tech companies, however, have called for a reduction in the pricing of backhaul spectrum. Currently, telecom operators pay the government 0.15% of their adjusted gross revenue for a single E-band carrier—or about ₹96 crore. That's about 3,000 times what telecom service providers in Iraq pay and nearly 1,400 times what TSPs in Saudi Arabia pay, the Broadband India Forum said. A carrier refers to a block or channel of spectrum that an operator uses to transmit wireless signals; more carriers mean more capacity, but also higher costs. India follows an escalating payment mechanism that involves charging 0.35% of a company's adjusted gross revenue for two carriers to as high as 1.45% and 2.30% for six and eight carriers, respectively. 'A rational SUC (spectrum usage charge) model which is flat, low, and predictable must be adopted for backhaul spectrum," Airtel said in its submission to Trai. 'Delinking SUC from number of carriers would not only promote efficient deployment but also help optimize access spectrum utilization and improve consumer experience." Jio has pitched a lower reserve price for spectrum based on the auction method and for easier spectrum payment terms. Satellite interference In another potential rift, satellite companies including Eutelsat Group, Amazon Kuiper and Inmarsat, represented by the Global Satellite Operators' Association, have urged Trai to move with caution as it looks to expand backhaul services in the 18 GHz band for telecom networks. The association said backhaul bands are critical to supporting mobile and fixed wireless infrastructure, particularly in regions where fiber deployment is not feasible. 'However, increased use of these bands must not come at the expense of satellite services that share co-primary status, particularly in the 13 GHz and 15 GHz bands," it said. The satellite operators association called for a balanced approach to ensure reliable operation of fixed satellite services, especially in frequency ranges that support essential services such as disaster recovery, remote education, and broadband access in underserved regions. 'As the Trai evaluates the potential expansion of spectrum assignment for terrestrial use in the 18 GHz band, Amazon encourages it to take a cautious approach," Amazon Kuiper told Trai on2 July. 'This band—which has historically been 'much less utilized" by terrestrial services to provide radio backhaul service in India—is critical to the Kuiper System's ability deliver reliable, affordable, and widely-accessible wireless broadband access to Indian consumers," the company said. In May, the department of telecommunications issued guidelines requiring satellite operators to submit a yearly plan to the government showing how they will gradually increase local manufacturing of ground segments of their satellite network in India. India has so far approved the applications of Bharti Enterprises-backed Eutelsat OneWeb, Jio, and Elon Musk-owned Starlink to launch satellite internet services in India, whereas Amazon Kuiper and Globalstar are waiting regulatory clearances.

Sebi bans Jane Street, says disgorge Rs 4.8k crore
US fund Jane St banned from D-St over 'mkt manipulation' MUMBAI: Markets regulator Sebi late on Thursday banned US-based foreign fund Jane Street from the Indian market for manipulating stocks and derivatives segments over several years to make huge illegal gains. Jane St, known for their quant-based trading strategies, has also been asked to disgorge nearly Rs 4,850 crore - illegal gains accrued to them by trading on the NSE between Jan 2023 and March 2025, a Sebi order said. This is the highest-ever disgorgement amount ordered by Sebi for any kind of illegal activity in the market. In an interim order, Sebi banned JSI Investments, JSI2 Investments, Jane Street Singapore and Jane Street Asia Trading, from trading in the Indian market until further notice. The markets regulator's investigation will continue. Multiple Strategies: So far, Sebi has identified two types of manipulative strategies. One was to buy heavily in Bank Nifty's 12 constituent stocks and futures in the morning session, then buying put options on the index, selling the stocks aggressively in the afternoon to pull down Bank Nifty that in turn pushed up index options prices to eventually make huge profits. The other strategy was to push for concentrated selling or buying in the last two hours of the expiry day to swing index levels and make investigation report noted that although Jane St incurred some losses in some parts of the trades, profits from the rest more than made up for the losses. Rs 36,502 cr profits: Sebi's interim investigation showed that between Jan 2023 and March 2025, Jane St had made a total profit of Rs 36,502 crore. During that period, on Jan 17, 2024, the trading firm had made a profit of Rs 735 crore, the highest single-day gain for the now-banned foreign fund. NSE caution letter: While Sebi was investigating Jane St's trading activities, on Feb 6, 2025, NSE had issued a caution letter to Jane Street Singapore and its related entity, asking them to refrain from taking large positions in the Indian market and to refrain from undertaking certain trading patterns. However, in disregard of NSE's caution letter, and the group's commitments to the exchange, "Jane St was observed to continue to run very large (trading) positions in index options", Sebi's report said there is a strong case that the period of investigation as well as exchanges on which Jane St had traded could be expanded to unearth the full scale of manipulation in the Indian market by the US-based global quant trading giant. "The interim order has only looked at 18 major days of prima facie Bank Nifty index manipulation on expiry day between Jan 2023 and March 2025), and three days of nifty index manipulation on expiry day during May 2025," sources said. "Investigations into other expiry days, other indices (including across exchanges), and other potential patterns besides the two highlighted in the order will need to continue." "There should not be any major market impact from this enforcement action," sources said. "In the long run, the growth in market confidence, and a free and fair market, should aid responsible investing and capital formation."

Trump signs the ‘big beautiful bill' into law at July Fourth ceremony
In a dramatic Independence Day celebration at the White House , President Donald Trump signed into law a sweeping tax cut and spending bill, cementing a major domestic policy victory that extends his 2017 tax cuts, slashes social safety net programs , and boosts funding for immigration enforcement. The signing took place Friday evening during a highly orchestrated Fourth of July event, complete with a military family picnic, a flyover by a B-2 Spirit stealth bomber and two F-35 jets, and the annual fireworks on the National Mall. Trump, surrounded by Republican lawmakers including House Speaker Mike Johnson and Majority Leader Steve Scalise, called the legislation 'the greatest victory yet' of his administration and declared, 'We have officially made the Trump tax cuts permanent. This represents the largest tax reduction in our nation's history.'

Trump had insisted on a July 4 deadline, and the legislation was delivered just hours before his self-imposed cutoff. What's in the bill? The legislation extends the expiring 2017 Trump tax cuts, making them permanent. The White House touts this as a boon for economic growth, with Trump promising, 'Once this takes effect, our economy is going to soar.' However, independent analysts and the Congressional Budget Office estimate the package will add over $3 trillion to the federal deficit over the next decade and could leave nearly 12 million more Americans without health insurance. Key provisions include: Live Events Tax Cuts: Permanent extension of 2017 tax reductions, primarily benefiting high-income earners. Social Safety Net Cuts: Reductions of $1.2 trillion to Medicaid and food stamp programs (SNAP), including new work requirements for Medicaid recipients. Immigration Enforcement: Increased funding for border security and the construction and maintenance of migrant detention centers. Event Funding: The bill sets aside $200 million for events celebrating America's 250th anniversary next year. While Trump and his allies celebrated what he called 'the single most popular bill ever signed,' polls show the legislation is deeply unpopular with the public, particularly due to its cuts to health and food assistance for low-income Americans and the projected increase in national debt. A Washington Post/Ipsos poll found that while many support expanding the child tax credit, most Americans oppose the bill's reductions in food aid and Medicaid, and 60% find the expected $3 trillion deficit increase 'unacceptable.'
