Thanks for your help Clark, which is much appreciated.

On the complexity of handoff, isn't a gateway just another base station, connected via a satellite?

So, if there were terrestrial links directly to the phone rather than through a satellite, wouldn't the phone simply see perhaps 5 base stations instead of the usual 3 or 4 when using terrestrial networks? Wouldn't it simply talk to the base station requiring the lowest decibels? I say simply because I really have no idea what's involved in achieving that possibly very complex action.

Satellite links are inherently more expensive than the terrestrial links for Globalstar, so it would be good [in the long run when the Globalstar system is filling] to hand off to terrestrial links to save space in Globalstar's satellites for the more valuable calls which have to go via a space link because there is no other link.

I suppose that could be best done via multimode, multiband Globalstar phones rather than build out basestations to handle Globalstar frequency terrestrially. That frequency should be able to be filled with satellite calls, so there isn't really a surplus of Globalstar spectrum when they finally price it correctly and fill it up.

But maybe in very frequency-starved cities where bids are very high already or likely to be in future [such as Beijing, New York, Hong Kong, London] because subscribers will have a hard time finding some spectrum available at a reasonable price [due to huge numbers of subscribers per square kilometre], the Globalstar spectrum would have highest value serving somebody in the city than somebody out in the countryside.

I'd have thought a solution to that would be to fill cities with picocells - such as a few base stations in each mall, along Oxford Street in London in the various stores. That way the phones would only have to reach perhaps 50 metres to a basestation in the store next door. The boxes of gizzards are very small these days so a shop would be able to ensure their customers could use their phones by leasing space to cellphone service providers.

Motorola's patent might be a problem. Message 15292387
I guess you saw it. Do you think Motorola could stop somebody else using a noise vs price algorithm to display an instantaneous price on a CDMA handset so that when they want to make a call, they can defer the call if the price is too high due to noise in the system being high? Motorola's patent refers to circuits rather than noise as the price-limiting variable.

I just had a look at the Motorola patent again and it occurred to me that QUALCOMM [and Motorola] almost certainly included this patent in their renegotiation of CDMA patents a while ago which continued Motorola's rights to pre-1995 patents. I suppose QUALCOMM therefore has access to this patent. Perhaps somebody would like to ask QUALCOMM investor relations if they have access to Motorola's patent number 5,303,297. Go on somebody, send a fax to investor relations and ask them... John Goren, how about you? You're a legal eagle. Pierre?

Thanks again,
