September 30, 2004, 10:48 AM — With its eyes on the future of home entertainment and a relatively uncluttered band of radio spectrum, Cisco Systems Inc.'s Linksys division on Wednesday unveiled a line of IEEE 802.11g/a wireless LAN products.
The devices, including a router and clients for both notebooks and desktops, can provide Wi-Fi connectivity over either of two unlicensed radio bands. The 2.4GHz band, used by 802.11g, is also home to some cordless phones, microwaves and other devices that can cause interference. The 802.11a technology uses spectrum in the 5.0GHz band, where there is less competition from other devices and services.
Linksys, which Cisco acquired last year, launched the devices Wednesday at an event in San Francisco to promote its aggressive move into what it sees as a burgeoning market for home networking. Also at the Wednesday event, Linksys introduced a new video camera with a faster wireless LAN connection and unveiled a deal with Verizon Communications Inc. in which the carrier will provide Cisco VOIP (voice over Internet Protocol) adapters to customers of its broadband telephony service.
Linksys sees 802.11a as the emerging home Wi-Fi technology as consumers begin using more demanding entertainment applications, such as streaming music and movies, Linksys President Charlie Giancarlo said at the event. It has been used almost exclusively in enterprises, in part because of the relatively high cost of dual radios for networks that support both 802.11a and other Wi-Fi specifications.
Now, some consumer electronics vendors, such as Sony Corp., are aiming at 802.11a for their coming wireless entertainment devices. Both its speed and its relatively "clean" spectrum band make it ideal for entertainment uses, Giancarlo said. Like 802.11g, 802.11a offers a theoretical maximum carrying capacity of 54M bps (bits per second), compared with 11M bps for the earlier, widely deployed 802.11b technology.
Linksys's 802.11a/g products will ship next month with estimated list prices starting at US$89 for a PC Card or PCI adapter. A USB (Universal Serial Bus) adapter will cost $99 and a router will sell for $109. The PC Card and PCI adapter include WPA (Wireless Protected Access) security capability. All the devices will work with older 802.11b equipment as well.
