Negotiating with a 2 year old (aka Rising Expectations)

Dora.jpgIt was a long day of travel with the family, and while I am a bit more used to the rigors of travel, it is particularly taxing on the kids. My oldest responds one way to travel, invariably wanting to go swimming even when we check into a hotel late at night, just to burn off energy stored while in a cramped seat. My youngest, though, wants to try to regain the routine she is used to at home. To accommodate her, my wife and I packed her favorite blanket, her sound machine to help her sleep, and her favorite doll du jour. On this trip, though, when we got to the room, I quickly realized that I was not well prepared, when my little girl looked up at me and said it:”œIwantDora.” Read More »

Paradigm Shift in IP Mobility (CMIP to PMIP)

Mobile operators and service providers have been looking for efficient solutions to the inter-system IP mobility for the past fifteen years or so. The main motivation for starting that effort was the ability to continue an IP session when a host IP address had to change. The targeted IP sessions were those involving a transport level connection. This effort resulted in a new mobility protocol so called Client Mobile IP or CMIP. CMIP is a host-based protocol that allows a mobile terminal to keep its transport connection opened and continue to be reachable while moving. CMIP is a key component of the all-IP network today and it’s designed to provide a common IP layer mobility across different access technologies. Mobile operators owning several access networks of different types are allowed to provide their users with global mobility and session continuity via CMIP. Read More »

A Taste of Telecom Diversity

vietnam_map.gifThis week’s post is about a fascinating trip I’ve been on in Asia these last couple of weeks -- visiting Indonesia, Vietnam, India & Thailand. Each of these countries is going through tremendous transformation and the network infrastructure is key to them propelling themselves to a much stronger position in the world. The state of the telecom infrastructure for each of these countries could be topics of a blog or book, so let me focus this post on Vietnam. Getting off the plane in Hanoi reminded me of my first visit to Beijing in 1996 -- the airport, the officials, the process all seemed to be similar to what I recall in my first visit to China. Leaving the airport in the taxi, I suddenly felt that I had arrived in Bangalore -- small streets that are packed with cars, motorcycles, scooters and other transports. The ride from the airport to the hotel took about 1.5 hours in which I had time to ponder the current state of local economy, telecom market and infrastructure in Vietnam. Read More »

Coherent Experiences

“Seamless mobility” is a trendy industry buzz phrase, promoted by Motorola, Microsoft, Intel and many others. Any content available on any device across any network…sounds magical! Often this idea arises in discussions of fixed-mobile convergence. Yet systems that successfully span fixed and mobile are usually not seamless at all. On the contrary, fixed and mobile remain distinct, each optimized for its own constraints. Consider two highly successful systems, the Apple iPod and the RIM BlackBerry. Read More »

Meanwhile Back at the Ranch : What about CableCARDs?

backattheranch.pngWith all the talk about DCAS and secure download for cable and IPTV, let’s not forget CableCARDsUntil downloadable conditional access system (DCAS) and the IPTV Interoperability Forum’s (IIF) secure download become available for wide deployment, CableCARD and the ATIS (the Alliance for Telecommunications Industry Solutions) point of deployment (APOD) module (specs for which are currently near finalization) will provide present and near-term security solutions for both HFC cable and IPTV networks. It is very unlikely that CableCARDs will completely be displaced in the next two years by any downloadable solution and, even longer term, may be a coexisting technology. Read More »
