ITExpo: BYOD – The New Mobile Enterprise

If you are going to ITExpo West 2012 in Austin, make sure you attend my panel on this topic at 1:30 pm on Wednesday, October 3rd.

The panelists are Jeanette Lee of Ruckus Wireless, Ed Wright of ShoreTel and John Cash of RIM.

The pitch for the panel is:

BYOD (Bring Your Own Device) has been in full swing for a couple of years now, and there’s no going back. Enterprises have adopted a policy of allowing users to use their own devices to access corporate networks and resources. With it comes the cost savings of not having to purchase as many mobile devices, and user satisfaction increases when they are able to choose their preferred devices and providers (and avoid having to carry multiple devices). But the benefits don’t come without challenges — the user experience must be preserved, security policies must accommodate these multiple devices and operating systems, and IT has to content with managing applications and access across different platforms. This session looks at what businesses can do to mitigate risks and ensure performance while still giving your users the device freedom they demand.

3G network performance test results: Blackberries awful!

ARCchart has just published a report summarizing the data from a “test your Internet speed” applet that they publish for iPhone, Blackberry and Android. The dataset is millions of readings, from every country and carrier in the world. The highlights from my point of view:

  1. 3G (UMTS) download speeds average about a megabit per second; 2.5G (EDGE) speeds average about 160 kbps and 2G (GPRS) speeds average about 50 kbps.
  2. For VoIP, latency is a critical measure. The average on 3G networks was 336 ms, with a variation between carriers and countries ranging from 200 ms to over a second. The ITU reckons latency becomes a serious problem above 170 ms. I discussed the latency issue on 3G networks in an earlier post.
  3. According to these tests, Blackberries are on average only half as fast for both download and upload on the same networks as iPhones and Android phones. The Blackberry situation is complicated because they claim to compress data-streams, and because all data normally goes through Blackberry servers. The ARCchart report looks into the reasons for Blackberry’s poor showing:

The BlackBerry download average across all carriers is 515 kbps versus 1,025 kbps for the iPhone and Android – a difference of half. Difference in the upload average is even greater – 62 kbps for BlackBerry compared with 155 kbps for the other devices.
