Wireless

WiFi is not Secure

August 3, 2007

George Ou has an excellent write-up about how insecure Web 2.0 applications are over WiFi. The problem? Unencrypted traffic which can be recorded, analyzed and used against you. He starts with a basic example of a Gmail account getting hijacked. Even worse, using this technique you can potentially have your home address and your e-mail known to others who are lurking nearby and recording your traffic.

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.

Nokia N800 Question

August 2, 2007

I received the following question today regarding the Nokia N800:   I'm seriously thinking of purchasing the Nokia N800. Since it is strictly a wireless device is there really enough free public wireless to make the purchase worthwhile. I'd be using it in Central Florida (Daytona Beach, Orlando, Tampa)and Louisiana (New Orleans Metro)areas mostly. Also, along Interstate 10, between Jacksonville, FL and New Orleans.

ActionTec

July 29, 2007

Many of us are familiar with VoSky Technologies the company behind the business class Skype gateways allowing a company to leverage the myriad benefits of Skype within their corporate communications infrastructure. If you need to catch up, I invite you to read an article written on the topic of Skype trunking by yours truly about a month ago.   So while Skype and VoSky are likely familiar names, most people are likely not aware of the fact that the company is a wholly owned subsidiary of Actiontec Electronics, a leading provider of broadband connectivity solutions for consumers and broadband service providers.   In a recent meeting with Lesley Kirchman Director of Marketing and Brian Henrichs VP of Business Development for the company I became aware the company’s tagline is “Solutions For a Digital Life.”   The company has been around since 1993 when it was in the analog modem business. Over time they evolved to do what a few companies have been successful at… Listening to telco needs, delivering on them and actually having the telcos buy.   The company has sold over five million devices and has roughly 300 people in their Sunnyvale, CA headquarters in the US. I think of the company as the Linksys of the service provider world as they sell gateways in countless DSL varieties, IPTV solutions and even FiOS solutions for Verizon.   Some of the more recent products allow you to transport data and entertainment within a house via wireless, HomePlug and numerous other technologies.   Another area of focus is technologies such as TR69 and WT140 which help can enhance the consumer experience.

Emerson Network Power

July 29, 2007

The embedded computing market is one on in which it is difficult to differentiate one’s self as the market is based on open interfaces and architectures. But still, vendors are not sitting still and a market where differentiation is difficult, companies continuously up the ante on performance for the proverbial buck.   Case is point is Emerson Network Power Embedded Computing who recently announced a new high-performance, quad-core AdvancedTCA blade for communications infrastructure applications. Known as the KAT6200, the new field replaceable ATCA server blade features a pair of dual-core, Intel Xeon processors, a high-speed ATCA switched fabric, a mid-size AdvancedMC expansion bay, redundant IPMI system management, and an optional 2.5-inch SAS hard drive.   In a conversation with Jeff Durst, program director for Emerson’s Embedded Computing business I had a chance to learn about the new blade and what makes it different. One area is persistent memory.

Ixia

July 29, 2007

As Ethernet gets more complicated, so must the test systems needed to accurately ensure carriers are providing the best quality of experience for their metro Ethernet solutions. A few weeks back I had a chance to sit down with the team at Ixia and discuss their Carrier Ethernet solutions based on Provider Backbone Transport (PBT) and Provider Backbone Bridge (PBB). The company’s Ixia’s test products for PBT/PBB, along with those for Ethernet OAM/CFM provide network equipment manufacturers and carriers with all the tools needed to test the latest Carrier Ethernet solutions.   Ixia announced the above functionality as well as Bidirectional Forwarding Detection (BFD) as part of it’s IxNetwork 5.30 release, which is part of its Aptixia test framework.   Many of the largest service providers have adopted PBT/PBB as it reduces the cost and complexity of Ethernet transport while providing mechanisms for enhanced QoS.   “PBT/PBB is an important new part of the Carrier Ethernet solution over switched Ethernet,” said Michael Howard, principal at Infonetics Research. “Many service providers are evaluating PBT/PBB as a cost effective mechanism to leverage their switched metro Ethernet network and offer back haul for access networks, extend L2/L3 VPNs, and point-to-point (ELINE) services.

Radisys

July 29, 2007

One of the hottest areas of telecom is the open standards building block area, especially the ATCA and more recently MicroTCA spaces. The reason for the growth in open standards components is obvious. As technology markets move more rapidly and become commoditized at the same time, many equipment manufacturers are realizing they would rather be in the software business and not hardware.   So a company who once spent millions developing proprietary transcoding hardware will likely decide it makes sense to write transcoding solutions which run on ATCA-based systems instead. Why?

Spirent’s Testing 2.0

July 29, 2007

There seems to be an evolution in the testing market as these companies focus on delivering products and services enabling network equipment providers and carriers to test more services in less time. As networks become more commoditized and the competition to provide services continues to increase, quality of service is becoming more important than ever.   In a recent conversation with the new President and COO of Spirent, Rob Piconi, I had a chance to get Rob’s take on the future of testing and moreover learn about the company’s new testing offerings.   Rob’s message to customers is you need to deliver products and services as rapidly as possible and his company is best positioned to allow you to test these products and services before they are rolled out. Spirent he says has the deepest and broadest [testing] portfolio.   He points out how critical it is to work with the leading testing company when deploying FMC. And he has a point as in the world of fixed mobile convergence; you are dealing with wireless, wireline and potentially IMS.

Acision

July 29, 2007

When a single US phone company, Verizon reports that in one month, they were responsible for sending 10 billion text messages, you may want to stand up and take notice.   In order to learn more about the SMS space I decided to take a trip down to Plano, Texas where the UK-based Acision has one of it’s four US offices. The company was formerly named Logica CMG and is one of those companies most people never heard of but is responsible for providing technology many of us frequently use.   In short, the company is an enabler of various types of service provider messaging from SMS to voice and video. This month in fact the company celebrated it’s 15th anniversary of supplying the industry with Short Message Service Centers or SMSCs.   Thanks to Moore’s law and clever design, the capability of Acision’s SMSCs has dramatically increased over the years. In 1992 SMSC version 1.0 had a capacity of 10 messages per second.

Mavenir Systems

Instant IMS: No IMS Required   When I decided on the sub headline for this article I realized it might be viewed as potentially controversial. How, you may be asking can one have IMS without IMS? Well there is an answer to this question and it may or may not be what you are expecting.   You see the benefits of IMS are great. We all realize this fact and moreover service providers understand if they aren’t able to provide the benefits of IMS to their customers soon they risk losing revenue.
