Nortel jumps into the wireless LAN market

Nortel jumps into the wireless LAN market

Nortel Networks’ introduction of its first wireless LAN product offerings is an interesting play by the network equipment vendor. Company executives say the idea behind the products is to extend the vendor’s wireline infrastructure family. Another way to look at it is adding an alternative form of access — wireless — to that infrastructure.

Vice-president of Mobility at Gartner Group, Ken Dulaney, said Nortel’s wireless introduction was a step that all the wireline vendors would have to take.

“There’s still a lot of real estate to be covered [in the enterprise wireless LAN market],” he said. “What it’s all about is giving users a choice of how to connect to the Internet: wired and wireless. All the edge switches that ring the network will have to have this dual capability.”

The reason this dual capability was so important, he said, was because it created a “seamless” Ethernet environment, and extended to wireless the same level of security, functionality and reliability that now existed in the wired LAN.


The one exception, Dulaney said, was Cisco. While Nortel (along with many wireless LAN and wireless LAN “switch” vendors) was in effect enabling wired switches to deal with wireless traffic and manage radio transmission to some degree, Cisco seemed to be still betting on a more distributed idea.

Nortel et al, were pushing intelligence from the access point to the box in the wiring closet. Cisco was packing the wireless access points, that actually created the radio link with client devices, with a range of management features and network intelligence. Dulaney’s character­isation raises some interesting challenges for the wireless LAN market and for enterprise network executives.

The history of wireless LANs is one of very small-scale, proprietary networks, often in warehouses, or similar sites. That began to change, and change rapidly, with the ratification of the IEEE 802.11 standard. Finally, there was a standard for wireless networking, a key step in spurring enterprise adoption.

In talking with enterprise users, it is telling how quickly, and counter-intuitively, wireless LANs become complex when they consist of more than just a few access points. Add to this the sudden realisation by network executives that they have to deal with an Ethernet standard for wireless networking that almost completely lacks the tools, features and functions they associate with wireline Ethernets.


And, right now, there is no easy work-around to the complexity or the lack of tools. The wireline network vendors such as Nortel would seem to be ideally suited to address this enterprise pain point. But they are approaching this problem from the standpoint of the wireline net. They know switching. But how well do they know radio?

Conversely, a flock of startups as well as security gateway vendors such as Bluesocket and Vernier, and the traditional wireless LAN vendors such as Proxim and Symbol, are jumping into this confusion with the concept of a “wireless switch”. But almost none of the many vendors who have announced these products are actually shipping them, and many won’t be until mid- to late-2003.

These are all promising developments. But, right now, that’s all they are: promises that are developing into products.

In the meantime, enterprises that want, or need, to deploy wireless LANs have their work cut out for them.
