NetGear is to launch superfast Wi-Fi products, running at 100Mbit/s or faster, in the UK on Monday.

The router and cards are on sale in the US for $150 and $90 respectively, so expect them to be nice and cheap when they arrive over here.

Best of all, the speed boost can apparently be added to existing NetGear 802.11g, and 802.11a/g Wi-Fi products, through a firmware download.

The Super-G specification, created by Wi-Fi chip vendor Atheros, offers the possibility of boosting Wi-Fi speeds to parity with Fast Ethernet – a speed which most desktop users scarcely use.

Although it goes beyond the IEEE’s standards, several other vendors use Atheros chipsets. Broadcom has its own speed improving technology, as do a new player Airgo, and Virata, which bought Intersil’s WLAN business recently.

The WGT624 router, intended for small office and SOHO use, includes a firewall, NAT and intrusion detection. It also has Wi-Fi Protected Access (WPA), 152-bit WEP encryption, VPN pass-through and security logging.

The companion Super-G card, called the WG511T also works with existing 802.11b and 802.11g access points. The launch of both has been delayed a while, in order to fit UK power plugs, and get relevant approval.
