I knew Microcell's was up and running - heck you can buy a GPRS PCMCIA card from Fido! Roger's is up and running too (if you've got a Fido phone, do a manual scan for other services - Roger's network will show up, just can't access it), but they aren't launched yet.
It's great to here this - thanks alot there, AC;-)
Actually it's not CDMA (which is IFAIK less than GSM, it's the current protocol of all old US mobile networks, the new ones are GSM I guess)
Currently in the USA, and here in Canada, there are:
GSM/GPRS
CDMA
TDMA - which I like to call "Digilog", as its a real bastard cousin of GSM and Analog. When was the last time you actually heard static on your 'digital' phone? You hear it often on TDMA!
iDEN - Only real useful if you have the need for a two-way radio / phone
I work in the cellular retailing industry, and have used all five of the cellular technologies (Analog, iDEN, CDMA, TDMA, and GSM). Without a doubt in my mind, I far prefer using GSM and GPRS over any of the others, especially if you've got a dual or tri-band GSM phone. The speed of data transfer using GPRS (up to 128kb) is by far the best right now, not to mention the fact that the overall sound quality actually embarrasses the competition.
Although 3G is based on current CDMA technologies, it is so far away right now that, in effect, it is a moot point. Look at it this way (from a North American viewpoint, anyways) - 3G is currently a very, very developmental technology in Europe right now (currently only available in the Isle of Man, I believe), so it'll be years before its available as a cellular communication standard. Companies would be crazy to release a product for it now.
Keep in mind that anytime you see anybody using a mobile phone in Europe, Asia, or Australia, they are using a GSM phone. Too the best of my knowledge, I don't believe that there are any CDMA networks in Europe anywhere. Can anyone verify that for me?
Anyone know any more information about the new Blackberry that RIM is supposedly working on? Rumour has it that it will also have cellular capabilities as well. I haven't heard if it'll be GSM, TDMA, or CDMA (although CDMA and TDMA are unlikely, IMHO), but if it's a RIM product, it should be pretty good...
Well, the old BG-174 units that I used had no sort of heat dissipation at all, unless you count the sweat dripping off your back;-)
The new BG-4's however, have a receptacle for a big block of ice, which does a great job of cooling the oxygen to an acceptable level.
The only downside? For some damn reason, Draeger designed it so that as the ice block melts, it drips down your back, so you still end up getting soaked;-)
... the Draeger closed circuit breathing apparatus I used to use when I was on a mine rescue team.
The only downside to these units was the fact that after about 10 minutes of use, the air would start getting/real/ hot. The chemical reaction that took place when cleaning the CO2 out of the exhaled air made everything hot. After a half hour of use, it would start to get almost to hot to breathe, and even more so if there was strenuous work involved.
It takes to get into space is enough money, and a flight plan? Surely there's gotta be more to it than that, in regards to gov't licences or some such thing, wouldn't there be?!

So, is it gonna be on Rogers AT&T's new GPRS network?
