We have been writing about Wi-Fi for a long time, weather it's to do with indoor connectivity , competition with 5G or just a name change to something simpler. When we last wrote about WiFi 6, a.k.a. 802.11ax, we were expecting a quick adoption of the technology in the industry. We are still not there yet. You know what's strange? None of the new @madebygoogle gadgets from yesterday support Wi-Fi 6. Not the Pixel 5, not the Pixel 4a 5G, not the Nest Audio, and not the new Chromecast. pic.twitter.com/QtJ8iB9FeO — Ry Crist (@rycrist) October 1, 2020 Take for instance the new iPhone 12 supports Wi-Fi 6 in all their models as one would expect but none of the new Google Pixel phones (4a, 4a 5G and 5) support it. In fact none of the new Google devices support it. Which is rather bizarre. While we are still looking forward to Wi-Fi 6 becoming widespread, IEEE has already started working on the successor of 802.11ax, 802.11be - Standard for Information technology--Telecommunicati
This is a very nice and easy description of technology evolution.
ReplyDeleteCan you please help understand why USSD is not part of the 4G (EPC) and 5G (NGCN)? Will USSD get obsolete as the mobile networks phase out 2G and 3G? Would it not be challenging, considering that mobile banking as an evolving service is highly dependent on USSD? Thanks
There is an equivalent feature in LTE called USSI. Unfortunately it's not been implemented by many networks.
DeleteThank you Zahid. Why is that so? I am trying to evaluate from a third party perspective, whether investing in new USSD gateways is worth undertaking, or is it at a risk of obsolesce?
ReplyDeleteDepends on which part of the world. Areas where 2G and/or 3G will be around (like Sub-Saharan Africa) will continue using USSD. Western world now uses Apps to do the same things.
