The new AC standard is here. with up to 866Mbit over the air datarate. 256-QAM modulation. and 80MHz channels. 802.11a/n/ac opens up new possibilities and speeds never possible before. The SXT ac is a new member in our 802.11ac product lineup. currently two models are available with regular 28 degree antenna. and the SA model with a 90 wide beam- width sector antenna. Also supports 802.11a/n mode and is compatible with all legacy RouterBOARD devices. including Nstream and Nv2 protocols. Both devices come with Gigabit Ethernet. New products are backwards compatible- for example. you can replace your 5GHz 802.11an legacy Access Point with new 802.11ac product and your existing customers will still be able to connect to it.
