Ofcom has initiated a consultation regarding the future use of the upper 6GHz spectrum band. This move could potentially pave the way for sharing this spectrum between mobile and Wi-Fi networks. In the past, 500MHz of the lower portion of the 6GHz band was allocated for Wi-Fi use under the Wi-Fi 6E and Wi-Fi 7 standards. However, the upper part of the band, ranging from 6,425MHz to 7,125MHz, has remained a topic of intense discussion.
This spectrum’s appeal lies in its capacity to offer low latency, high capacity, and strong signal propagation. These characteristics make it attractive to both mobile operators, who see its potential to enhance their 5G services, and Wi-Fi providers, who can benefit from high-power and outdoor applications. Existing users like satellite services and radio astronomy stakeholders also have a vested interest and are seeking clarity and assurances from the regulator.
Ofcom has proposed a solution that might see the band divided between mobile and Wi-Fi networks. The consultation suggests immediate allocation of the whole upper 6GHz band to Wi-Fi, with a future split by 2027, designating certain portions more specifically for mobile use. If mobile networks are not deployed, Wi-Fi could use the entire band.
Moreover, there are plans to expand the use of the lower part of the band for high-power and outdoor Wi-Fi implementations. As Ofcom stated, “This new spectrum would provide a large increase in capacity for both mobile and Wi-Fi services, laying the foundations for future generations of data-hungry technologies, such as virtual and augmented reality, and AI. In a boost for the economy, it would also help mobile and Wi-Fi providers to deliver improved services to more customers, especially where demand is greatest.”
Ensuring alignment with European counterparts is a pivotal aspect of this plan. European nations are also exploring optimal uses of this spectrum and have targeted a harmonized decision by 2027. Such harmonization across the continent would encourage investment into this spectrum by manufacturers and service providers.
