The Wall Street Journal Placed Xirrus 3rd Among Technology-based Venture-Backed Companies and 9th Among All Venture-Backed Companies

Xirrus®, the Wi-Fi “Power Play” that delivers the most coverage, bandwidth, and user density in the industry has been ranked by The Wall Street Journal 3rd among technology-based venture-backed companies and 9th among all venture-backed companies, showing once again the strength of their leadership team and continued growth in Wi-Fi networking. Xirrus’ ranking in The Wall Street Journal’s “The Next Big Thing – The Top 50 Venture-Backed Companies” was based on the success of its venture-capital investors (August Capital, Canaan Partners, Gold Hill Capital, InterWest Partners, QuestMark Partners, U.S. Venture Partners); the amount of capital raised over the last three years; the success of its founders and chief executive (Dirk Gates); the recent growth in the value of the company; and a qualitative ranking among the Dow Jones venture-capital reporters and editors.

“We are extremely pleased with the recognition by The Wall Street Journal for our leadership team and financial growth,” said Dirk Gates, founder and CEO of Xirrus. “Sales of our high performance Wi-Fi Arrays continue to grow significantly as more and more organizations see the value of Wi-Fi networking as a means to increase efficiencies of their users. Mobility is the growth area of enterprise telecommunications and Xirrus is the only Wi-Fi platform designed and implemented with the same distributed model as wired switching that puts the power and intelligence at the edge closer to the end user.”

I received a following set of questions via email and thought that rather than only respond to the one individual, but post it on WiFiJedi.com for general consumption.

Here’s what I received:

I have recently done a deployment where the customer is using 802.11n in both 2.4 and 5 GHz range.  I have configured a WLan with that is providing coverage for all the radios including a/b/g/n on a 4402 controller in WiSM Module.  The clients are also unable to run on all the radios.  Everything is working fine, but we are seeing clients that have been connected to either a 2.4ghz radio or 5ghz radio, tend to switch between them when running for a while.  I am trying to understand this scenario, since there is no setting on the controller that I can find would allow the preference of the radio.  we are currently running the latest 6.0 code on the WLCs.  Secondly the data rates are set to 24Mbps or higher for both radios, that means 802.11b is not allowed.  The client machine was sitting at one position for 24hrs that means the user was not moving around hence the roaming should not be involved I think.  Lastly we did the survey for 802.11a coverage and I don’t think there is any issue with the coverage, since it connects to 802.11a at excellent.  The question really is that once the client connects to 802.11a on excellent and is running on that radio for an hour perfectly and the user is not moving at all why is it that it switches itself to 802.11g and then again to 802.11a??  I wanted to get your opinion as if do you know any bugs or vulnerabilities by having both radios enable?

And here is my response:

Thank you for your message.  Unfortunately, at this time most/all of the roaming decisions are made by the stations (laptops, etc.) and not the infrastructure (Access Points and WLAN Controllers).  The IEEE is devising a standard to change this, but it will take some time.

What type of stations are you using?  Are they laptops, or something else such as handheld scanners, Voice-over-WiFi phones, etc?  If they are laptops, are they Windows or Macintosh?   If you are using Windows based laptops, you may be able to set a preference for 5 GHz within the client driver.  For example I have an Intel 4965 AGN adapter — if I right-click on my wireless adapter and select “properties”, then click “configure” I can select the Wireless mode to be 802.11a/n only.  I can also set the roaming aggressiveness so that it roams less frequently.  Macintosh computers have a natural preference for 2.4 GHz and it is more difficult to encourage them to connect to something at 5 GHz – in a case like that, you may consider adding a 5 GHz SSID on its own VLAN.  Again, these roaming decisions are made by the station, so your best bet is to look at the laptop settings to see what you can tweak.

One other potential “gotcha” that came to mind was how you enabled 802.11g only.  The data rates have to be carefully managed for full interoperability between the station and the infrastructure.  There are two types of data rates – the “basic” rates and the “supported” rates.  The basic rates should include all 802.11g rates, even below 24 Mbps (therefore you should double-check that the basic rates include 6,9,12, and 18 Mbps).  The requirements for supported rates are less strict.

For those of you that are local to Phoenix, I will be speaking about wireless networking and security to the Phoenix Chapter of ASIS (American Society of Industrial Security) tomorrow, February 17th.

The meeting is being held at the University Club:

39 E Monte Vista Rd
Phoenix, AZ

It is a lunch meeting with registration starting at 10:45 am. Lunch and networking are before the presentation, which starts at approximately 12 noon. There will be a Q & A session to follow.

My employer, Xirrus, is starting a series of videos called “Wi-Fi Busters”. Each episode will explore a certain myth around wireless communications. The first episode is around the myth that Wi-Fi causes adverse health effects.

This video is less than 3 minutes and is both fun and informative — check it out!

For those of you unfamiliar with some of the regular features of WiFiJedi.com, I publish poll questions on Tuesdays.  Normally, these are multiple choice poll questions where the answers are shown in percentages.

However, this week I would like to ask the poll question in a slightly different manner. This time, I would like to ask an open ended question and for you to answer within the comments section.

Without further fanfare, this week’s question is “What do you think is the Top Wireless Story of 2009?”

I am going to compile and publish a list of such stories and I would like YOUR help to ensure I didn’t miss any of the best stories.  :)

There are only a few more shopping days before Christmas.  If you have procrastinated until this point, perhaps you should view the “wireless gift guide” I recently published on my Computerworld blog.

I have one addition to the list:

  • BlueAnt Supertooth Light – I can’t believe I excluded this one from the list because I actually *received* one of these as a Christmas gift this year.  It’s a Bluetooth speakerphone/microphone that hangs on a car sun visor.    And as Sheldon from the TV show, Big Bang Theory says, “Everything is better with Bluetooth”.   I actually had a similar device from a different manufacturer and didn’t like it –mostly because it wasn’t loud enough.  The call quality on both ends is excellent with the BlueAnt device.

I also wanted to expand on two of the original suggestions:

  • PlayStation3 – The Wi-Fi on this does a lot more than I originally anticipated. Not only does it allow for free online game play, but it facilitates game updates.  Once such example of this is in sports games where updated team rosters can be downloaded from online servers.  You can also stream movies directly to the PS3 from NetFlix.

Wondering what to get friends and family members for a last-minute holiday gift?   Then check out my latest Computerworld blog post for gift suggestions.  I won’t spoil all the fun, but I made four suggestions that deal with Wi-Fi, Bluetooth, and other wireless technologies.

If you are still puzzled about what to purchase, check out the Super Tuesday Poll that I ran here at WiFiJedi.com to see what wireless-related gifts others are buying for their loved ones.

Happy shopping!

InterWest Partners Leads Latest Investment Round in the Only Wi-Fi Power Play in the Industry

Thousand Oaks, California – December 1, 2009 – Xirrus, Inc. announced that it has secured an additional $20 million in a financing led by InterWest Partners.  This financing round brings the total investment in the company to $80 million.  Xirrus will use the new funds to bolster its reserves and strategically invest in partnerships with large integrators focused on making Wi-Fi the primary network connection for their customers.  The financing is anticipated to be the last round of private funding Xirrus will require.

“Times have changed since my last technology venture,” said Dirk Gates, founder and CEO of Xirrus (previously founder and CEO of Xircom, which was valued at more than $2.0 billion before being sold to Intel® in 2001).  “Xirrus has reached critical mass and significant customer traction with far less fanfare, yet far more substance than venture-backed companies during the 1990’s. We have quietly outpaced the competition by outperforming them on nearly every level – products, productivity and capital efficiency – as evidenced by many thousands of successful deployments, with 100% customer satisfaction, while growing at a compounded annual growth rate of nearly 250% over the past three years.”

Xirrus also announced the appointment of Khaled Nasr, Partner at InterWest Partners, to Xirrus’ board of directors.  Mr. Nasr joins current Xirrus board members Dave Marquardt of August Capital; Steve Krausz of US Venture Partners; Eric Young of Canaan Partners; Bill Schroeder, former Vice Chairman of Connor Peripherals; and Dirk Gates, president and CEO. All existing venture investors including August Capital, US Venture Partners, Canaan Partners, and QuestMark Partners participated in the round.

“We have been monitoring the Wi-Fi industry in search of a viable investment for several years, but have been dissatisfied with the lack of differentiation and leadership among the vendors,” said Khaled Nasr, Partner at InterWest. “There was one Wi-Fi vendor, however, who had the leadership, vision, and products we were looking for.  Xirrus not only has a management team with proven operational abilities, but they also have the vision and products to take Wi-Fi to the next level – to replace wired Ethernet to the desktop with wireless connectivity.”

I recently wrote on my Computerworld Blog about wireless resources on Twitter.  The goal of the post was to share ways for those passionate about wireless networking and security could find one another.   One of the comments to that post was from Jamey Kistner (@jameyk1stner).  Jamey recommended another such community, this time on Ning.

The Ning community is called “802.11 Heaven” and is accessible at http://80211heaven.ning.com/ The website’s subtitle is “The place to chat, argue, debate and understand all things 802.11″.  The site was founded by Tom Carpenter (@carpentertom), who is a CWNA and CWSP author.

To be honest, the 802.11 Heaven community is extremely small at this point, but it definitely has some of the best minds in Wi-Fi including Joel Barrett (@joelbarrett) and Keith Parsons (@keithparsons).  Let’s get the word out as the value of the community is strengthened with each new member!

My thanks goes out to Jamey for highlighting this resource.  Speaking of resources, you might also want to check out Jamey’s blog “Wireless Journeys”, which is available here: http://wirelessaficionado.wordpress.com/
