Canadian authorities restrict the use of 5G networks

Canadian authorities recently announced plans to restrict the use of 5G networks near most of the country's major airports. The announcement stunned the telecommunications industry, which was completely unprepared for the scale and severity of the planned restrictions.

The telecom industry spent over C $ 9 billion on licenses in a recent 5G wave auction, with Canada's Big Three (Rogers, Bell, and Telus) spending over C $ 7 billion. The industry will also invest billions in 5G infrastructure and equipment over the next few years.

According to Telus Corp., the proposed restrictions could reduce the cost of 5G spectrum (C $ 2 billion) by C $ 100 million: "The operator was very surprised when, just a week after making a multi-billion dollar commitment, he learned that it would be harmed like this." In another statement, Telus said, "and the mobile industry as a whole has been taken aback by the government's new policy."

The government is concerned about radio signals from 5G equipment, which interferes with adjacent frequency altimeters and is used in automatic guidance systems. Recently auctioned 5G radio waves are in the 3500 MHz frequency range, while aircraft radio altimeters operate in the 4 200–4400 MHz frequency range.

The proposed limits are going to be pretty tough. For example, at Pearson International Airport in Toronto, the federal government will ban the use of 5G base stations in the vast area around the runways themselves, resulting in no 5G service in the area.

Telus says the operator was simply not prepared for the extensive and excessive restrictions that the government is now considering. The operator adds that other countries have introduced smaller “buffer zones” to combat the same problem.
