The 2023 World Radio Convention (WRC-23) will happen in Dubai from November 20 to December 15, and one key agenda merchandise is the consideration of the identification of the 6425-7025 MHz and 7025-7125 MHz frequency bands for both Worldwide Cell Telecommunications (IMT) or unlicensed Wi-Fi designation. Because the convention approaches, there are just a few key factors for regulators and policymakers to bear in mind, together with the present and anticipated demand for indoor wi-fi and the timelines related to utilizing the bands for 5G and 6G in comparison with Wi-Fi.
The worldwide momentum round Wi-Fi can’t be overstated. In accordance with IDC, there are 19.5 billion Wi-Fi gadgets world wide that carry nearly all of wi-fi community information site visitors. And this momentum has elevated with every technology: Wi-Fi 6 reached 50% market adoption extra shortly than earlier Wi-Fi generations; the identical report predicts that 473 million Wi-Fi 6E gadgets will ship in 2023; and now, Wi-Fi 7 is on the cusp of a market growth, with growth and adoption anticipated to choose up considerably in 2024, significantly within the face of heightened consumer demand for larger reliability wi-fi broadband. Because of options like Multi-Hyperlink Operation, Wi-Fi 7 will ship deterministic low latency for wi-fi broadband in a approach that earlier generations haven’t.
“This momentum relies on having the 1.2 GHz of spectrum that the 6 GHz band gives,” Broadcom’s Director of Product Advertising Chris Szymanski advised RCR Wi-fi Information, including subsequently, that an IMT identification threatens to stall the expansion of this much-need expertise in lots of international markets. The 6 GHz band introduces a brand new stage of capability and reliability that 2.4 GHz and 5 GHz can’t present, making it completely important for the way forward for Wi-Fi and Wi-Fi-supported functions.
As a result of the overwhelming majority of community site visitors happens indoors, Wi-Fi gives the most suitable choice for connectivity more often than not. Additional, Wi-Fi is already supported on almost each system, whereas mobile connectivity is primarily restricted to smartphones. With the addition of 6 GHz, Wi-Fi turns into much more highly effective as it may possibly help future, bandwidth-intensive use instances like enhanced broadband and AR/VR functions.
And for these restricted indoor use instances that really require the ultra-reliability of mobile, there exist already a number of choices together with small cells, distributed radios, neutral-host networks and personal 5G networks. Subsequently, whereas corporations working to safe end-to-end broadband for houses and companies like Broadcom acknowledge that mobile will finally want further spectrum, the trade overwhelmingly feels that right this moment’s spectrum is enough to handle present use instances in most cell situations.
In distinction, enhanced Wi-Fi shouldn’t be solely wanted proper now, however can be able to hit the bottom working. “The ask for an IMT identification shouldn’t be well timed,” mentioned Szymanski. “You’ll have main markets that will have deployed three generations of Wi-Fi earlier than your very first IMT deployment.” In different phrases, 6 GHz-based Wi-Fi is prepared for deployment and use right this moment, whereas enabling indoor 5G and 6G with 6 GHz would take between seven to 10 years.
Recognizing this danger, Apple issued a proper assertion declaring that it sees “a big distinction in deployment timescales” between IMT and Wi-Fi for the thought of bands. “Licensed Wi-Fi 6E gear for the total 6 GHz band (5925-7125 MHz) is delivery right this moment… for the USA market and others the place rules are established, and it’s unclear when IMT will likely be accessible,” acknowledged the corporate. “We advocate that Wi-Fi shouldn’t be constrained by any protracted IMT timelines.”
In one other submitting, Amazon, HPE and Meta collectively declared 6 GHz “not an acceptable band for IMT” and that if such a designation got, “it’s more likely to be solely sparsely utilized in very particular places.” In distinction, 6 GHz Wi-Fi is already accessible in a number of main markets.
An IMT identification for the 6425-7025 MHz and 7025-7125 MHz frequency bands would hinder Wi-Fi’s progress — and subsequently the advantages it’s able to delivering right this moment for customers — and for not a lot achieve as it’ll as a lot as 10 years earlier than 5G or 6G are commonly making use of 6 GHz spectrum.
