TRAI initiates discussion on assignment of microwave spectrum in lower 6 GHz, E and V Bands
New Delhi, May 28 (PTI) Telecom regulator TRAI on Wednesday floated a consultation paper on assignment of the microwave spectrum in lower 6 GHz, 7 GHz, 13 GHz, 15 GHz, 18 GHz, 21 GHz bands, as well as E and V bands.
TRAI has fixed June 25, 2025 as deadline for comments and July 9 for counter comments. You may be interested in
"...a consultation paper on assignment of the microwave spectrum in 6 GHz (lower), 7 GHz, 13 GHz, 15 GHz, 18 GHz, 21 GHz Bands, E-Band, and V-Band has been placed on the TRAI's website for seeking comments and counter-comments from stakeholders," the regulator said.
In 2022, Department of Telecom (DoT) had approached TRAI to provide recommendations for assignment of spectrum in E&V bands and Microwave Access (MWA) as well as Microwave Backbone (MWB) spectrum in the said frequency bands.
Post that, TRAI had released a consultation paper on assignment of spectrum in E&V bands, and Microwave Access (MWA) & Microwave Backbone (MWB) for soliciting comments of stakeholders on the subject.
Meanwhile, the Telecommunication Act, 2023 was enacted in December 2023.
In light of the provisions of the Telecommunications Act, 2023 in respect of radio backhaul for telecommunication services, TRAI, via a letter in February 2024, conveyed that the telecom department may want to review its 2022 reference.
"In response, DoT, through a fresh reference letter dated 13.09.2024, while agreeing to the TRAI's observation that backhaul spectrum is a part of the First Schedule of the Telecommunications Act, 2023 for which the assignment method would be administrative, requested TRAI to provide recommendations under Section 11(1)(a) of the TRAI Act, 1997," TRAI said.
The aspects included demand assessment and scope of service/ usage for 57-64/ 66 GHz (V-band) and 71-76 GHz/ 81-86 GHz (E-band) and accordingly methodology of assignment of spectrum and associated terms and conditions.
Other facets included spectrum charges and related terms and conditions such as spectrum cap, carrier aggregation for assignment of spectrum in the six bands for backhaul purposes of commercial telecom services.
A typical public telecommunication network consists of the access network; core network; and backhaul links.
The access network is the last mile connectivity to consumer devices, while core network connects the access network to global public networks. The backhaul links are used to connect the access network with the core network.
In all, TRAI has put over 50 questions to stakeholders for views.
These include level of demand of the spectrum in these traditional backhaul bands; the commercial services for which these bands should be assigned; and the method for such assignment. Other queries raised include the associated terms and conditions, validity period of assignment, and rollout obligations.
"As the 7125-8400 MHz range in the 7 GHz band and the 14.8-15.35 GHz range in the 15 GHz band are being considered for IMT in WRC27, whether there is a need to review the usage of 7 GHz and 15 GHz microwave backhaul bands at this stage itself, or should the review be undertaken after considering the outcome of WRC-27," TRAI asked.

Real cost of flying 40 pc lower than a decade ago, says IATA DG
New Delhi, Jun 2 (PTI) The real cost of flying has fallen 40 per cent than a decade ago despite rising cost and tax challenges, global airlines' grouping IATA's Director General Willie Walsh said on Monday as the number of air travellers is projected to cross 5 billion annually. At the IATA annual general meeting, which is taking place in India after 42 years, Walsh also said the rate of growth in the airlines' industry has slowed down as a result of supply chain issues. The International Air Transport Association (IATA), which represents over 350 carriers globally, on Monday projected that airlines will make a profit of USD 36 billion on USD 979 billion revenues. The expected profit this year translates to a net margin of 3.7 per cent or USD 7.20 net profit per passenger. "Our profitability is not commensurate to the enormous value that we create at the heart of a value chain supporting 3.9 per cent of global GDP and providing and supporting jobs for 86.5 million people," Walsh said. Despite ever increasing cost and tax challenges, he said the real cost of flying is 40 per cent less than a decade ago. India is one of the fastest growing civil aviation markets in the world and air traffic demand is on the rise while there have been concerns about airfare trajectory. Meanwhile, referring to the supply chain issues that have been impacting the aviation industry, the IATA DG said that regarding aircraft, the manufacturing sector is failing badly. "The delivery backlog of 17,000 implies a 14-year wait between ordering and delivery... the number of deliveries scheduled for 2025 is 26 per cent less than what was promised a year ago," he said. More than 1,100 aircraft under 10 years of age are in storage, which Walsh said is 3.8 per cent of the entire fleet, nearly three times the pre-pandemic comparison of 1.3 per cent. Also, the annual fleet replacement rate of 3 per cent is well below the normal 5-6 per cent. "This hits revenues because some demand goes unmet. And scarcity pushes up maintenance and leasing costs. "It's just not acceptable that manufacturers estimate it could take until the end of the decade to sort this mess out," Walsh said as he also advocated for keeping aerospace outside of trade wars. According to the IATA DG, bad regulation can destroy value and stand in the way of affordability. "The litmus test for any regulation is cost-benefit analysis. As business leaders we take this much more seriously than regulators. They are not playing with their own money and the difference between political success and solving a problem is often wide. That makes bad regulation far too prevalent," he said. While talking about safety, Walsh said less than half of the accident investigations over the last six years have been published a final report. "Missing insights from accident reports are lost safety opportunities," he noted. Last year, there were seven fatal accidents among 40.6 million flights, and 244 fatalities among 4.8 billion passengers. In the last 12 months, Walsh said two civil aircraft were downed in conflict zones, several airports with civilian aircraft on the ground were bombed in military operations, and incidents of interference with navigation systems near conflicts rose sharply.
