2-Megabit Bandwidth for Your Cell Phone 114
A reader wrote to us with the latest wireless advance from Qualcomm: 2.4 megabit bandwidth for cell phones. They call it high data rate and are hoping to compete with cable modems and other personal high-bandwidth subscription methods. Me, I just want to have a usable cell modem.
Where does it say Cell Phone? (Score:1)
I didn't see anything about Cell phones in that article. It looked like something that you would use at home if you can't get DSL or a Cable modem.
However, I do think this is great. I can't get DSL or Cable where I live, and I know I would be interested in that kind of bandwidth.

The 2.4GHz band seems like its going to be mighty crowded. I have a 2.4GHz Zoomair network that runs at 100mW and a 2.4GHz camera from X10. The camera seems to run on a lot less power as it would work a block away through houses, it works only a few feet when the network is running.

No DSL or cable in the area I live, the price I pay for seeing a corn field across the street.
Even if this is shared bandwidth, the advantage of a rural neighborhood is that there are less people to share it with. In the city I'd price it a little over land line solutions so that it didn't become bogged down, but still make it affordable. In the country I'd just want it affordable.
Unfortunatly digital cell phone isn't avaiable in all rural areas, in fact I have a couple friends who live where no analog cell phones can be had. Still, I'm close enough to the city and the freeway that I might get it.
Another *promise* from Qualcomm (Score:1)
When actual rollout occured, it was shown that traffic handeling capacity increased only on average of 20-30%. Furthermore because CDMA uses live handovers (a mobile terminal in motion is in contact with two base stations at once) the battery use is excessive.
Infrastructure providers were also pissed bacuase a CDMA base station usually runs anywhere from 50% to 200% more then a TDMA base station. COnsidering the fact that when an operator sets up a network, they buy several hundread to thousands of base stations. Sprint didnt beef their network up because of these costs and becuase of this, well just go talk to any Sprint PCS provider to see how bad the coverage is.
Qualcomm is notorious for pulling ridiculous stunts in the telcomm industry. e.g. Dr. Irwin (is that name correct?) and his buds actually had the nerve to walk into the ITU-R back when the 3rd Gen cellular global standards were being hashed out and actually *demand* that they use IS-95 (narrowband CDMA) or Qualcomm would refuse any IP liscensing. ITU-R promptly smacked them down and told both Qualcomm and Ericsson that if they cant sort their IP problems out, any form of CDMA will be ruled out for 3G.

While I agree that GSM is better technology, I'd not buy a GSM phone right now (even tho I had one over the summer) because the coverage is too limited. Of course, 2 Mbit might change that, but... But back to the main point, I like the choice... it creates competition and allows providers to find niches. Here (in Pittsburgh) we have
AMPS, served by BellAtlantic, which is good for the casual "emergency" and weekends and evenings user.
TDMA 900, served by AT&T Wireless Services, which is good for business travelers who travel a lot, especially on the road, and don't want exorbiant analog roaming charges.
CDMA 1900, served by Sprint PCS, which is good for a casual traveler who wants to pay less (than AT&T) but still wants roaming to all big cities without exorbiant roaming charges.
GSM, served by Ariel, which is good for the European traveler, as well as a city-only casual user (per second rounding is nice...)
Cmpanies don't necessarily put themselves in these niches (ie if I walk up to AT&T Wireless Services and tell them I'm looking for a cheap plan but I want cheap digital roaming, they won't point me towards Sprint PCS), but these are just the niches where they're the cheapest/best plan. If everything were one technology, there'd be no competition.
Also, wireless giants are giants. If there's market, there are people to throw at phones, and there's enough competition that you really do want to innovate. Europe's innovating GSM for us, Sprint is innovating (kinda... wireless web) on CDMA 1900 for us, AT&T should be (I don't know what they're up to) innovating TDMA 900 (Motorola sure is...), and AMPSi s on it's way out. I think it's the best of both worlds: large companies pay for consumer's choice. I'm not saying our technology is better, it's not. It's just that we have more choice.

Rural areas need bandwidth the most (Score:2)
2MByte or 2MBit, either way mobile telephone bandwidth can only help the most bandwith-starved areas of the world- the rural ones.
I live a bit out in the sticks as my wife points out [demon.co.uk] ( Cotswolds, UK [custodian.com] ). Whilst I'm only 500 metres from the telephone exchange, my 'phone line takes a 4 kilometre detour through three neighbouring villages before it gets there. Which means that ADSL [bt.com] and BT ISDN Highway [bt.com] are out of the question.
I consider myself pretty lucky to get 49.3kbps from my telephone line. People in rural parts of America, Asia or Africa will be getting far less.
Yet it is rural areas that need the Internet most. Why would townsfolk want cable TV, teleshopping, multi-user chatlines and home offices when the video shop, supermarket, pub and place of work are on their doorstep? These amenities are often not available to rural users where not only remote location, but sheer lack of numbers, make even subsidised facilities uneconomic.
It is high-bandwidth wireless services like GPRS [gsmdata.com] that will lead the revolution, not cable.
If the post office has to send written data nationwide, regardless of urban or rural boundaries, for the same price, why shouldn't telecoms operators be forced to send digital data nationwide, regardless of urban or rural boundaries, for the same price?

Basically, the network is composed by a set of cells that (ideally) cover the area where costumers are. Those cells are served by Base Stations. The Base Stations have antennas, and those antennas, being non ideal, have a certain directivity. As most users are on the ground, the antennas are designed to have their best response in the direction pointing from the Base Station to the ground (usually -3 to -10 degrees). On the other hand, the antennas have the worst directivity in the areas that there are less users (you don't want to waste your power). So antennas do not send almost any power towars the air (or the ground below for the same reason).
That is mainly why you can't use a mobile phone in a (flying plane).
As for the data rates, they are in MegaBITS per second (Mbps), not MegaBYTES per second. And those claims are just theoretical. All 3G (3rd generation) proposed architectures claim speeds up to 2Mbps when the user is still or walking at very low speed, and up to 384 Kbps at velocitis of up to 500 Km/h! (This is so that you could use your phone on a (future) high speed train to connect to the Internet).
But those are theoretical fields, and (almost)everybody working in this field (as I do) believes that the real data rates will be of 384 Kbps when STILL and about 114 Kbps when going at high speed (but probably not that high!).
About the frequency plan that somebody asked about I recomend to check the 3GPP and the IMT2000 sites, where you'll find tons of info about 3rd generation mobile phones. And by the way, Qualcomms proposal is only one among many others, although most of them are based on Wideband CDMA technology, and the only comercial(narrowband) CDMA network is Qualcomm's IS-95, which is mainly deploid in the US, Brazil and some oriental countries. Qualcomm's CDMA proposal is called (last time I checked!) cdma2000, although the extension of IS-95 is cdmaOne, and I don't know if the one they are talking about in this article is the first or the latter.

Don't forget latency (Score:1)
There is one thing the article is very silent about: latency. Due to the way a cellular phone system works (all calls have to pass through your home server), wireless networks have high response times (or latency).
Increasing the bandwidth doesn't change a lot about this. It means you have to implement larger windows (= the number of packages you sent before you wait for an acknowledgement) in order to take advantage of the higher data rates.
A wireless network is not as reliable as cables, so most of the time, you have to resend some packages. And this resending is not efficient (you have to wait for an ACK basically after each package).

This was like a catalyst for all the other PCS operators who were basically waiting for Sprint to make up their mind. You have to understand that noone wanted to built an island surrounded by the big Sprint with no way to roam. These licenses are *expensive*.
Had Sprint decided otherwise, the whole wireless world would be a different place. Not only would we have real, global roaming, but cheaper phones (more volumes), a bigger market for wireless data and, last but not least, easier agreements on a new G3 standard.
While I'm all for competition and choices, having an own American standard on this is not in the interest of consumers.

This is not true. There is competition all over Europe. I think there is at least two competing companies in every large country. In Sweden we have three, and they all use the same technology. This is also good for the customer in that it is easy to change provider. You have your phone and it can be used in any of the available systems.
The Swedish companies also provide different call plans and different services. They have also competed on coverage, but I am not so sure that is important when you choose a provider any more simply because they all have good coverage now.

What hasn't helped matters is that major cell providers won't agree on what technologies they want to use. Some say CDMA, some TDMA, and some are still using, *gasp* HDII Analog.
Now add in the fact that other countries have a much larger usage of cell phones than the US and you get a much larger need for mass standardization. Some countries have little infrastructure so far as telecommunications is concerned. This is when it makes the most sense to use cells and cell standards. If you can't drag in a land line to everyones, well, then drop in one micro-cell in the neighborhood (perhaps with a wireless link itself) and everyone can use their cell phones as if it were their home phone (which, for many people outside of the U.S. it is).

FWIW, the first generation of qualcomm's chip you will only see something like 153.6kbs or maybe 384kbps data rates on the downlink, 14,4kpbs on the uplink. It remains to be seen what data rates you will see in the first generation chips from qualcomm's competitors. (I would expect at least some of the qualcomm alternatives will do 384kpbs in both directions and simultaneous voice and data.) The IS-2000 spec, however, provides for up to 2.1mbps in both directions. (this is not counting the FCH and DCCH physical channels which will do 14.4kbps each). --AC
