Architecting a Reliable Wireless Network

Few question that the age of mobility is upon us. The emergence of a global economy is facilitated by the basic mobility of goods, services and people. For many, the idea of mobility has become second nature. Of course, the structures for mobility -transportation, logistics, infrastructure -must be robust and reliable lest the mobile quickly become immobile. Given this, it is critical that the wireless industry focus R&D on improving netwo…


SP CTO Update

IETF-IAB sent key leadership members to participate in the meeting as representatives of the Internet…

Businesses don’t deploy an IEEE specification; rather, a standard that guarantees interoperability. The same rings true for 802.11n. Wh…

Downloadable Security : Both Sides of the Fence

A lot has been written about a downloadable conditional access system (DCAS) in the cable industry (including a post I wrote a few weeks ago), but what’s going on over on the telecom side of the video marketplace? In the IPTV arena, we’re working through the issues relevant to secure download within the IPTV Interoperability Forum (IIF). Our approach will use some similar technologies to what DCAS is delivering for cable, but it is…
