it seems wimax will be history and some see it even today as a sort of left over. around 2012 the role out of lte can be expected. but that's not in the hand of the engineers, but will be a question of policy and business models. auction anyone?

There has always been a five year period of “euphoria”, followed by a five year period of pain (commercial and/or technical), followed by five years of “pleasure” and another five years of “perfection” which leads to boredom by engineers and back to an euphoric stage. | jane zweig: the crystall ball was clear 10 years ago ... it is clear today

some engineers are bored already with lte and started to work on g4 1/2 and g5, anyhow some others are still thrilled by optimizing algorythms for gsm.

btw re-wording has a kind of tradition in this field: right now they are searching for a new wording for lte, as it doesn't make sense to call it "long term evolution" any longer. some centuries ago they renamed gsm to global system for mobile communication. at the beginng it was anything but global. it was truly european brought to you by the groupe spécial mobile (gsm).

don't look at the glossary list for wireless. it's a never ending story. before 3g was in place they already talked about 4g today its 5g. who cares. the problems are the same:

• can i use it abroad
• how much does it cost
• what does it offer
• what performance can i expect.

somehow i have the feeling in the wireless world they like to create new problems before the solve the old ones.

two tickets for the danish public transport system, for residents and for tourists, with some desired and undesired side-effect, depending what your interests are:

officially tourists should aim for the single ticket with rfid: called "milfare ultralight". no cryptography, but also more expensive than the normal one and no discount for seniors, but after all that seems less important.

the other ticket solution seems to be for residents: provided with the "milfare classic chip", cryptography is added as money can be stored: anyhow: hacked

The first reported attack was designed by two students at the University of Amsterdam, Pieter Siekerman and Maurits van der Schee. They analyzed the single-use ticket and showed its vulnerabilites in a report. They also showed how a used single-use card could be given eternal life by resetting it to its original "unused" state. For this work they won the Joop Bautz award. | Andrew S. Tanenbaum
