ReefEdge's New WLAN Switch

ReefEdge's New WLAN Switch 12/02/2003 12:32 AM
ReefEdge is moving out of its niche space into the broader WLAN networking world: Nancy Gohring's report on ReefEdge's new WLAN switches for InfoWorld reveals a company that's changed its focus from policy-based WLAN management of homogeneous devices to a range of devices that allow RF management of APs from several vendors, and small-office networking. This is a pretty classic company development: customers certainly told them about the gaps in the line-up from all vendors, and ReefEdge moved to fill them. I hear from small offices all the time looking for devices that have enterprise-scale features but without the enterprise-scale price tag because their per-user cost would be 10 or 20 times the enterprise's due to a lack of economy of scale....

WLAN Switch Vendors Starting to Die?

WLAN Switch Vendors Starting to Die? 10/28/2003 11:09 PM
Since WLAN switch developers started coming out of the woodwork, it was clear that the market couldn't support all of them: Trapeze and Vivato have both laid off workers recently, leaving some to wonder if they are struggling. Trapeze made a name for itself by spending liberally on marketing and what some in the industry have described as a massive booth for trade shows. A company spokesperson in this article says that the cut backs happened on schedule. Trapeze cut 30 percent of its staff and Vivato laid off 25 percent. I would be surprised if Trapeze was one to go under straight away as it seems to have a robust product. But as we all know, the best product doesn't always win. This will be an interesting space to watch as acquisitions and failures are bound to start happening soon....

WLAN Switch in an Access Point

WLAN Switch in an Access Point 03/29/2005 11:28 AM
Xirrus launches its wireless LAN array: In a briefing last week, Xirrus executives explained that their product combines the utility of a wireless LAN switch with a single footprint that can coordinate frequency and signal pattern across as many as 16 channels using a combination of 802.11a and 802.11b/g with sectorized antennas. Gigabit Ethernet carries the traffic to and from the array; a redundant failover Gigabit Ethernet port and a 10/100 management port ensures throughput. The WLAN array comes in three configuration: four ports, eight ports, or 16 ports (models XS-3500, XS-3700, XS-3900). All three models can work in 802.11a, b, or g mode for each radio, with up to 12 for 802.11a and up to four for 802.11b/g. Xirrus has baseband-level control of the radios which allows them to adaptively and dynamically change the signal strength and antenna scope. Because they're sectorized, that means each radio can serve a greater distance if needed than the typical indoor omnidirectional antenna--or back off as the RF environment requires. The arrays have what are now required features of any switch: VLANs, multiple SSIDs per switch (up to 16), QoS, and assignment to VLAN based on authentication, SSID, or other factors. One of the radios on any model can be set to work as a monitor for security threats, like rogue access points. The arrays can be managed using Layer 3 tunneling with a centralized platform, the XM-3300, which can handle up to 500 WLAN arrays. Because there's an extra 10/100 interface, the management can be entirely out of band of the actual network traffic. The arrays are powered with 48-volt DC which requires either direct electrical wiring for an AC adapter or the use of DC power over Ethernet--not the standard kind, but their 48-volt variety--that ties into their Remote Power System (XP-3100) at over 300 feet of Cat 5 Ethernet cable. The Xirrus array is the logical extension of the WLAN switch concept. One of the early gating factors for WLAN switching was the necessity for all traffic to be routed from an access point back via Ethernet to a physical switch which had to manage all the data coming and going. While this added the benefit of VLAN-based roaming that was independent of a physical switch location, it also tied bandwidth to the computational and switching capacity of that centralized switch device. (Symbol's first "access port" system had only...

WLAN switch makers continue to duke it out in the marketplace: Even though analysts have been predicting consolidation for a while, not much has happened and in fact new competitors, sometimes in the form of established equipment vendors, continue to enter the market. Recently I've noticed press releases coming out to announce practically every new customer win as the switch makers look for recognition. This piece mentions a few such announcements that came out today, including that Aruba is building a network for Ariba and expanding the network at Dartmouth University. Airespace also announced it is building a network at Galluadet University in Washington, D.C....

Cisco Intros WLAN Switch Module

Cisco Intros WLAN Switch Module 05/05/2004 02:04 PM
Cisco introduced today its wireless LAN services module, an add-on to its Catalyst 6500 switch that integrates support for WLANs: Coupled with Cisco APs (wireless access points), the platform offers some of the functionality of other WLAN switch platforms but has some drawbacks. One of the most important capabilities that Cisco executives stressed during a Webcast this morning was the ability for users to roam between APs in 50 milliseconds--fast enough to support voice. The client is authenticated at the AP where traffic is sent through a secure roaming tunnel back to the Catalyst switch, which could be located anywhere in the network. As the client roams, its IP address stays the same, so voice calls, VPNs, and other applications aren't interrupted when the client associates with a new AP. Because all traffic travels through the switch, roaming might not always happen in under 50 milliseconds. Cisco tested roaming between two APs that were located in Perth, Australia. The APs were connected to a switch that was located in Sydney, a distance away from Perth that is similar to the distance between Los Angeles and Miami. The handoff time increased to around 250 milliseconds, slow enough for an audible blip in a voice call. But applications are not dropped during that time. Cisco also said that it is releasing an upgraded version of its wireless LAN solution engine (WLSE), Cisco's management software for APs across an enterprise. The new version not only detects rogue or unauthorized APs, but can remotely disable the switch port that the rogue is connected to. Also, with the new software, customers can set their Cisco APs to scan-only mode. Customers who may not be ready to deploy a WLAN may still want to ensure that rogue APs aren't being deployed. "Over time they will deploy a WLAN, and the same APs they use for scan-only can be used as regular APs," said Bill Rossi, general manager of Cisco's wireless unit. (Airespace, a WLAN switch developer, has a similar offering, which has the added feature of deassociate signal bombing a rogue AP to prevent clients from successfully remaining connected to it.) The upgraded WLSE also supports instant AP deployment without having to configure the AP before adding it to the network. When the switch module recognizes that a new AP has been plugged in, it alerts the WLSE system, which sends the configuration file to the...

Big WLAN on Campus

Big WLAN on Campus 01/06/2005 03:14 PM
Colleges are the bleeding edge of WLAN technology: I wrote this piece for Mobile Pipeline (my first for them) which started out as a more general best practices article for giant WLANs, and morphed into an article about college WLANs. Why? As I explain in the story, giant WLAN enterprises don't want to talk on or off the record about what they're doing. Academic institutions are happy to oblige. Schools also have the disadvantage of having to support many, many generations of equipment and operating systems. You can't tell a professor to take a flying leap, and some schools may still have five-year-old laptops and desktops that still have to be integrated. It's clear that 802.1X is the next big trend for both schools and enterprises. It solves many problems while adding tremendous policy flexibility. Using 802.1X and L2TP means that you can have smaller VLANs that are segregated by policy, group, or even randomly to balance users among VLANs....

More Voice Over WLAN Deals

More Voice Over WLAN Deals 03/06/2004 01:49 AM
Alcatel and Nortel are both promoting voice over WLAN systems by reselling WLAN equipment from Airespace and handsets from SpectraLink: Cisco started selling voice over WLAN handsets last year and ironically it appears that move is actually good news for SpectraLink, which has been making such phones for many years. That's because Cisco competitors like Alcatel and Nortel need to sell voice over WLAN systems to customers but certainly won't sell Cisco phones. Instead they'll use SpectraLink's. This story included some interesting figures form Forrester Research about WLANs. The study found that 20 percent of companies have or are in the process of building WLANs. About 15 percent of companies said they had completed or were in the process of rolling out voice over IP systems, but the story doesn't distinguish if that refers to voice over WLANs or voice on regular wired phones. I suspect that the companies that have deployed voice over WLANs are concentrated in certain market segments like factories or warehouses. It's likely that there are few companies in standard offices using voice over WLAN as the benefits are less clear and because building a WLAN to support voice is a more challenging proposition than constructing a WLAN just for data....

Found this rather neat article on The Register, infact, it was something I was discussing with a bunch of friends at college last week! Nice to know we are being heard.

Car makers BMW, Audi, Daimler Chrysler, Volkswagen, Renault and Fiat have won a German government grant to help develop the basis for a standard method for car-to-car wireless data.

NOW is focusing on 802.11 technology and IPv6 to develop "inter-vehicle communication based on ad hoc networking principles". Essentially, it's exploring ways that moving vehicles can automatically set up temporary links with other cars, bikes and trucks in the vicinity, and share traffic information.

With routing capabilities, the whole thing could become a huge 'automobile Internet', with vehicles warning each other - and their drivers - about slow-downs, bad weather, accidents and other road problems.

On a personal note, I really can't even begin to imagine the possibilities here, a road traffic innovation, chat/P2P/file sharing heaven on the roads, or a big headache for the RIAA/MPAA/BSA? It could definitely be all of the above! One thing is for sure, you'll never get bored in traffic anymore.

Interesting Take on Voice Over WLAN

Interesting Take on Voice Over WLAN 02/19/2004 12:43 PM
Radioframe is touting its indoor GSM system as better than voice over WLAN: Radioframe sells a platform that extends cellular coverage inside an office building and connects to the office PBX so companies can use their cell phones inside the building. When users are in the building, minutes are cheaper than outside on the wide area cell network. The company's CEO argues that even though usage of the WLAN in the building doesn't cost, the handsets are so much more expensive than cell phones that it makes more sense to use a system like Radioframe's. I did a story a while back on voice over WLAN and found that the handsets cost around the same as standard wired office phones. So the difference could come down to a decision about whether a cell phone offers the same features and functionalities that workers typically want on their phones in the office. Plus, the Radioframe CEO didn't discuss how the costs of deploying and maintaining its network compares to deploying and maintaining a standard WLAN....
