Your network is currently comprised of both 802.11b and 802.11g devices. You have extra funds at the end of the year to upgrade part, but not all, of the wireless infrastructure. You want to upgrade to the latest technology while maintaining backward compatibility. Which standard should you go with?

802.11ax is the latest Wi-Fi standard and offers several improvements over previous standards, including higher data transfer rates, increased network capacity, and better performance in crowded environments. It is backward compatible with older Wi-Fi standards, including 802.11b and 802.11g, which means that devices using those standards will still be able to connect to an 802.11ax network.
By upgrading to 802.11ax, you can benefit from the latest technology and improved performance while ensuring that your existing devices can still connect and operate on the network.
