WiFi Spectrum Debate Affects PS5 Pro Release

The recent release of the PlayStation 5 Pro has sparked discussions about its availability in India. Sony announced that the console would not be available in certain countries, including India, due to restrictions on the 6GHz wireless band. This situation marks the evolving landscape of WiFi technology and spectrum allocation.

About WiFi Frequency Bands

WiFi technology primarily operates on two frequency bands – 2.4GHz and 5GHz. The 2.4GHz band offers broader coverage but limited data speeds. In contrast, the 5GHz band provides faster data transfer but covers a smaller area. Since 2002, these bands have been de-licensed for use in India, allowing for indoor and outdoor applications.

The Evolution to WiFi 6 and 6E

With the introduction of WiFi 6 in 2020, both frequency bands were used more efficiently. WiFi 6E emerged in 2021, introducing the 6GHz band, which can theoretically achieve speeds up to 9.6Gbps. Countries like the U.K. and the U.S. began allowing the use of this band, creating a divide between regions that support it and those that do not, such as India and China.

Current Status of 6GHz Spectrum in India

In India, the 6GHz band is allocated to the Indian Space Research Organisation (ISRO) for satellite communications. This allocation has raised concerns about potential interference with WiFi. However, experts suggest that satellite operations are unlikely to disrupt WiFi usage . The Government of India has until 2027 to decide on the future of this spectrum.

Industry Interest in 6GHz Spectrum

Telecom operators in India are keen to access the 6GHz spectrum for future 5G and 6G deployments. Meanwhile, tech companies like Google and Meta advocate for using this spectrum for WiFi, similar to practices in the U.S. The debate continues as both telecom and tech sectors vie for control over the 6GHz band.

Implications for Consumer Electronics

The ongoing discussions about the 6GHz band may not drastically impact consumer electronics in India. Major brands like Apple and Samsung have devices that avoid using the 6GHz spectrum despite supporting it. Sony could potentially release a version of the PS5 Pro that does not rely on this band until regulatory changes occur.

Future of WiFi Technology in India

Despite the lack of 6GHz spectrum, WiFi 7 technology can still function in India. Advances in WiFi are not solely dependent on new frequency bands but also on improved efficiency and simultaneous use of existing bands. As a result, WiFi 7 routers can still offer high speeds, surpassing current home broadband capabilities.
