Dave, that patent is a complete joke as far as CDMA is concerned. It has NOTHING to do with CDMA.

That soft handoff patent said that the great idea was to check an adjacent base station for the same frequency when switching over to a closer base station. If the same frequency was available, the handset would be left on that frequency.

You see, the TDMA systems have lots of little slots and little frequency channels which are allocated solely to a particular handset. They can only operate in silence. Any other noise is static, interference and end of the conversation.

By finding the same frequency available, the handset could be switched without the clunk and risk of a dropped call which then commonly happened.

It had NOTHING to do with CDMA developments despite Ericy pumping it up as "WE invented CDMA with our soft handoff patent from a decade ago in 1988." Then getting it renamed a couple of months ago and combined with other patents in a pathetic attempt to put the magical letters "CDMA" in the patent.

A CDMA system doesn't check to see whether the adjacent cell has got the frequency available - it always uses that same frequency. The fact that CDMA uses the same frequency doesn't mean that Ericy invented the idea, the mechanism or software for doing it, or CDMA.

It boggles my mind to think that any patent person, technical person or joker on the street couldn't see that Ericy is talking rot on that patent. Of course lawyers would instantly see that TDMA is exactly CDMA; in fact even more CDMA than CDMA itself as TDMA has a whole range of frequencies which might be handed off in a soft way! But lawyers just fiddle with word play ["I did not have sexual relations with that woman!" Well, perhaps true enough in a narrow sense] and don't have to make the laws of physics actually do anything and as long as they are paid, they'll believe CDMA was invented by Ericy, and OJ was innocent [Can you believe that woman is going to marry him - and she's a lookalike of his first wife apparently. I wonder what his children will think of him when they are 21 and can think. I bet they get a bit curious about what happened to their Mum. There might be some more drama still to come!]

PS: This is not a slagging of lawyers. Some of my best friends are lawyers. Many of them are not in jail. They always aim to act in a moral, ethical and honest way, always ensuring they are paid up members of the Lawyers Guild before temporarily using client's trust fund money for urgent personal needs. They do agree they maintain a monopoly, but their monopoly is a GOOD monopoly for the good of humanity. Unlike that wicked $ill Gates who has got far more money than they have.
