Hughes Systique Corp Interview

August 9, 2007

I recently had a chance to interview Arjun Roychowdhury, Director, IMS & Broadband Applications Hughes Systique Corp. Arjun will be a speaker at Internet Telephony Conference & Expo in September and I thought it worth getting his thoughts on a number of issues.   Please outline your new corporate initiatives.   We have started a SIP & IMS Technology consulting service that has hit a niche in the market. There are many market IMS services (VDC, In-Stat, Gartner etc.) but no pure 100 percent technology consulting solutions. To address this space, my company consults in SIP & IMS technologies, helping OEMs migrate to IMS, architecture consulting and standards update via subscription services.

T-Mobile VoIP

August 9, 2007

Andy Abramson really likes T-Mobile’s VoIP plan based on a potential new device the company could be rolling out soon in the US. What is the device? Something which allows FMC for the home and small business market. It allows up to two SIM cards to be embedded in it meaning it can likely support two mobile phones.

Voice Peering Growth

August 8, 2007

Last year I proclaimed it the year of VoIP peering. 2007 is becoming the year of rapid VoIP peering growth. Case in point is the Voice Peering Fabric or VPF who recently stated they have reached a 200 billion minute run-rate up from a 100 billion minute run-rate in October 2006.   I recently had a chance to see the VPF’s New York location at the Telx carrier hotel at 60 Hudson Street. Believe it or not, this was my first trip to 60 Hudson.

Apple iPhone

August 7, 2007

I finally went to the AT&T store this past weekend and played around with the iPhone. Amazingly the store in Norwalk, CT had both models in stock. I was very surprised by this fact as the building is right next to Costco and the cost-conscious retailer has thousands of people streaming into the store daily.   I was surprised at how few people were in the AT&T store actually. It seemed the kiosk for Verizon and Sprint in Costco was busier than the AT&T store.   My impressions of the phone are exactly what I thought they would be.

Telephone System Channel

August 6, 2007

If you aren’t aware, TMC has built with its partners, the largest collection of business to business online communities in the communications and technology space. Channels are micro communities which live on the left navigation of TMCnet menus. Global Online Communities are in yellow and live in the top navigation area of TMCnet’s home and other pages.   The latest channel/micro community we have built is in partnership with IPitomy and is called obviously enough the Telephone System Channel. On this channel you will find all the information on telephone systems you could ever want.   For example, here is an article which discusses research firm ABI’s thoughts on SIP and how it is transforming telephone systems today.

WiFi not Secure – Clarified

August 6, 2007

I just received this e-mail from Francois Doremieux, Senior Program Manager, Product Group: Customer Experience in response  to my WiFi is Insecure post from last week. I thought it worth sharing.   ----   Hello Rich It was a pleasure meeting you in Redmond last month.   I just read your "WiFi is not secure" article and I wanted to add a brief comment.   As we discussed in Redmond, the notion of security and quality at the network layer is only one way to look at it. I agree that it’s possible to snoop and intercept the packets over WiFi. Therefore, one cannot trust the network layer alone for security (as we had discussed in Redmond that it is not possible to trust the network layer alone for management of quality). That is why the approach we have taken with Microsoft UC is to provide security at the application layer, with strong authentication, non repudiation, signaling and media encryption (in the same way we did it for quality with the adaptive media stack).   Transport is a very important element of the stack, but it can’t solve all issues (and its solutions tend to not have the flexibility software brings to the application layer).

700 MHz Setback

August 3, 2007

Just when youthought it was safe to jump into the 700 MHz frequency with your own device along comes the Federal Communications Commission's Office of Engineering and Technology (OET) who says initial testing of the prototype devices showed they failed to swiftly track and avoid interference with other, licensed broadcasts.   The report stated the technology coalition behind the tests had hoped the use of so called white spaces - an unlicensed spectrum between TV channels -- would pass muster with regulators as early as October. The coalition effort is one of several efforts on the part of large companies offering Internet services and devices to expand options for consumer access to the Web.   The group includes companies such as Microsoft Philips, Google, Intel Corp., and Dell Inc. Members of the coalition want the ability to offer devices and services that don't have to be used on licensed networks operated by traditional telecom or cable companies.   But the OET’s test results put a damper on the group’s hopes, noting that "the sample prototype white space devices submitted to the commission for initial evaluation do not consistently sense or detect TV broadcast or wireless microphone signals."   Hopefully there will be a way to solve this dilemma. After all, the above companies represent some of the smartest technology minds in the world.

ITEXPO Weeks Away

August 3, 2007

I just can’t believe that Internet Telephony Conference & Expo is five short weeks away. I just can’t wait for September 10-12th in Los Angeles. Boy is the summer going by fast. Thankfully I read Ken Kamp’s blog where he talks about the show and it reminded me about the timing of this event.   Tom Keating too reads Ken’s blog and he beat me to writing about Ken’s post.   I am very excited about the show… It is just amazing how much the communications market has evolved in a few short years.

iPhone, U-Phone, Everybody G-Phone

August 2, 2007

This year has been the absolutely most tumultuous ever in terms of wireless communications and these changes can and will have a dramatic effect on your business. You can’t go anywhere these days without seeing Apple’s iPhone in action. Kids have them, Mac loyalists have them and most importantly, your coworkers have them.   The question is… How do you support them and what policies and procedures do you need in place to ensure you are ready for the onslaught of questions and interoperability issues this phone will bring to the market.   What about security? How will we deal with the potential for these devices to get lost without the ability to remotely wipe confidential corporate data?   If a single-industry changing phone wasn’t enough for telecom and IT managers to deal with, we now have Google’s G-Phone (or it could be called Google Phone… Time will tell) looming in the telecom wings just waiting to disrupt the service provider business model and potentially the way you plan and negotiate your wireless telecom contracts.   Then there is the 700 MHz spectrum with it’s potential to enable an army of devices on new wireless spectrum.
