Sprint Details Shift To LTE

New submitter jmeboi writes "Engadget reports that Sprint has announced a rollover from WiMAX to LTE for its 4G needs. The company is 'converting its 1900MHz holdings and LightSquared's 1600MHz spectrum ("pending FCC approval") to LTE,' and also re-purposing the section of 800MHz spectrum that was set aside for the defunct iDEN push-to-talk network. 'The company plans for a rapid deployment of this new 4G, with the first LTE markets and handsets to hit in mid-2012 with the full rollout mostly completed by 2013. Current subscribers signed up for WiMAX plans won't have to worry, as their devices will continue to be supported throughout 2012.'"

It's still tolerated for voice because voice uses so little bandwidth, but it's completely unsuitable for data. That's why the CDMA carriers rolled out 3G years before the GSM carriers. The CDMA carriers just cranked up the bandwidth of their voice hardware (which is why you cannot simultaneously talk and use the web on CDMA 3G - they use the same radio). The GSM carriers had to come up with an entirely new network protocol and hardware based on wideband CDMA, then graft it onto GSM in order to compete (which is why you can simultaneously talk and use the web on GSM 3G - their voice and data use different radios).

      CDMA has no realistic limit(something near a trillion) on how many users it can handle other than signal clarity and processing power. CDMA is EXTREMELY resilient to noise. CDMA also has a cool thing called a soft hand-off. A phone can talk to multiple towers at the same time, so even if the primary tower loses signal, the call doesn't get interrupted.

      GSM can't do this because each tower has a difference frequency/channel, which means it has to completely drop contact with its primary tower before switching.

CDMA specs for a phone to be able to communicate with up to 7 towers at once, but typically 3 is the implemented limit for a phone.

      Another cool thing is CDMA actually runs *at* background level. The signal strength at the receiver is approximately the same as background noise. I reiterate, CDMA is built around the idea that noise doesn't really matter.

      Upgrading is also easier. GSM, you need to allocate more channels and make sure there isn't much noise on those channels. Eventually, you run out of channels and no more users can be supported in a given area for all carriers.

      Then I gave him a target. I told him he had to lower my bill to no more than $100/month for the same services I had now. And I gave him five minutes or I'd hang up without warning.

      He didn't come up with the $100 limit unless I'd turn off the MiFi, but he said I could turn it off without early penalty, and that he'd give me information on an unadvertised plan that lets you turn it on when you need it and off when you don't. He gave me an entire month free, and he gave me a 20% discount for the life of my stay with Sprint.

      I told him i'd wait until I received a bill showing the changes and credit, and until then I'd only pay $100/month (it sometimes takes months for the Sprint bills to catch up to promises, if ever). I told him that if I was threatened with disconnection in the meantime I'd ignore the notices, and if I actually was disconnected I'd walk over to the MetroPCS store. I hung up without waiting for his reply.

      "CDMA does require more power to operate during peak usage times."

      depends on if you're talking about the radio or the processing. CDMA is very process intensive, but the radio is very low.

      CDMA phone Power: 0.001watt-1watt(avg 0.2watt) Practical Range Limit: 75KM(no logical limit) - Noise almost doesn't matter and is moderately influenced by structures.

      Partially true. CDMA is sensitive to interference, and need a very tight control on power level to be efficient. In practice, this means that a CDMA phone usually transmits at low power. The maximum power is 23 dBm if I remember correctly, but the phone transmit power distribution is centered around 0 dBm.
      The way to transmit data is different between CDMA and TDM based system. In basic CDMA there is still a notion of frame, but it is rather long (10 ms from memory). Several user are transmitting on the same frame, using different code spaces. In the end, the tendency is to transmit for a long duration but at low power. TDM based system on the other hand tend to transmit for a short duration at higher power.
      With HSPA, we go back a bit toward shorter allocation units (TDM like), while still being CDMA. When possible (user close to the cell, so limited interference to others cells) the system will allocate a unit to a single user (or very few) and use a higher power to use higher modulation and coding scheme and pack more bits/Hz. This "closer to TDM" way of using CDMA is more efficient.

      Also, GSM has a limit on how many users it can handle because of the limitation of available channels(FDMA) and how many users it can multiplex via TDMA per channel.

      CDMA has no realistic limit(something near a trillion) on how many users it can handle other than signal clarity and processing power.

      All systems have a limit. In practice 3G CDMA uses a maximum of 256 codes, so you could only have a theoretical maximum of 256 users at a time (and of course much less in practice). Yes in theory you could use larger code spaces, but it's just not practical and nobody does this.
      There's been a lot of hype around CDMA, and it does have advantages. The big one was to make single frequency deployment practical for the first time, and this helps increase overall capacity. But there's no magic, and when it comes to number of users it's just a different way to split the channel capacity: with TDM it's one user at a time, taking the full channel. With CDMA, it's all users at the same time, taking a fraction of the channel maximum capacity. In the end there's no advantage there, just different ways of slicing the resource.

      CDMA is EXTREMELY resilient to noise.

      TDM, CDMA or OFDMA are about equivalent when it comes to robustness to noise actually. The difference comes from what modulation and coding schemes a standard supports and there may be some differences, but the TDM vs. CDMA vs. OFDMA is not a factor. And the issue is not so much thermal noise but interference in a mobile network. There the way to handle it changes significantly depending on which family is used. But CDMA (as all) is sensitive to interferences, and handling this was the main difficulty in making CDMA work in practice. Actually, it's always the most difficult thing to handle in cellular, whatever the scheme ;) But there was a complexity jump with CDMA.

      CDMA also has a cool thing called a soft hand-off. A phone can talk to multiple towers at the same time, so even if the primary tower loses signal, the call doesn't get interrupted.

      GSM can't do this because each tower has a difference frequency/channel, which means it has to completely drop contact with its primary tower before switching.

      That is true, but note that soft HO is not specific to CDMA. It's part of the IEEE 802.16e spec for example, although it's not part of the WiMAX profile (WiMAX features are a subset of the IEEE spec, same for WiFi and IEEE 802.11). And it

      The root of Sprint's thrashing problem is the RIL programming that prevents simultaneous wimax and CDMA (EVDO or 1xRTT) data sessions. Now, when a Sprint phone attempts to connect to Wimax, it first terminates any live data session (EVDO or 1xRTT) before it even tries to authenticate to Clear. Likewise, if the wimax connection fails (or is failing), the phone will first fully terminate the wimax session before it even tries to establish a CDMA data connection.

      What Sprint really needs to do is give us an option to keep a hot EVDO or 1xRTT data session as a live backup whenever wimax is active, and have the phone establish a fairly conventional multilink VPN with dynamic failover to a VPN server somewhere (favoring wimax, but transparently rerouting data to EVDO or 1xRTT the moment a failure occurred). That way, applications and the outside world would both see a stable IP address, regardless of how ugly things got between the phone and towers.

      Technically, this is entirely possible to do with the phones we have RIGHT NOW. In all of Sprint's current phones, the wimax and wi-fi radios are on the same daughtercard (in fact, I think they're the same chip). If it weren't possible to do simultaneous 1xRTT and wimax, it wouldn't be possible to do simultaneous wi-fi and voice calls, either (voice calls and 1xRTT work the same way). It's a shame the radios aren't as hackable by end users as Android itself is. Otherwise, I'd give it 3 months, max, before custom modems started to appear that could use thirdparty VPN services together with simultaneous CDMA + wimax data connections to achieve instant failover. Battery life would probably suck, but at least you'd never find yourself swearing at Connectbot because you forgot to disable 4G before connecting, then at some point the phone spontaneously decided to kill your SSH session so it could try and connect to a new wimax tower it just noticed....

For far too long in the states we've had so much confusion and complication because of CDMA vs GSM. I'm glad that the CDMA carriers (Verizon and Sprint) are finally upgrading to a better standard.

    I'm dreaming of a future where the USA will be like the rest of the world, where we'll be able to buy an unlocked phone, and use it on any carrier we chose. I'm currently using an unlocked phone, but my choice in carriers is limited to just AT&T (being as T-Mobile doesn't cover here). It's still cheaper, if you buy an unlocked phone, and then get a prepaid SIM card. Life would be so much simpler if all the carriers supported one standard, and an LTE phone would work with any network.

    It might be Apple that pushes us to this point. As they've repeatadly shown, they prefer to only build one model of phone. The iPhone finally got a CDMA variant last year, but this year, it's all one model again, because they found a chip that supports both CDMA and GSM, as well as all 3g frequencies. Apple wants to build an LTE phone, and all carriers want to have it, and Apple will not want to build two different LTE phones. Meaning we'll get one LTE phone, and as LTE is backwards compatible with GSM, it requires a SIM card. When they do that, and other manufactures start doing it, we'll see an era where it might just be possible to buy an unlocked phone in the USA, and be able to buy a SIM card from any network you want to use.

    This is my dream, but I'm thinking there has to be a catch. Why would the carriers want this kind of arrangement? They want to be able to lock people in, because they don't want to compete based just on who has the best service / price. But maybe, this is just an inconvenient fact for them, as the rest of the world moved on and developed standards, and in our global world, it just doesn't make sense to have your own proprietary standards anymore. CDMA is dying, and now so is WiMax. Both standards were only used by a few carriers, manufacturing phones and equipment to support them was more expensive just based on economies of scale, and they were unfriendly for the consumer. GSM is vastly more consumer friendly than CDMA, in terms of convenience and customer choice.

Cable - the most expensive package is like $45 with premium and pay per view extra. Internet over cable - 30mpbs/8mpbs on DOCSIS 2 (yes, not like the lying US cable that require docsis 3 for anything above 15mpbs) for $35 bundled with a lot of cable. PON to the home - no problem starts from $3 per month and can go up to $20. Installation cost is never more than 1 month cost. As well as DSL which is not that competively prices considering the subscription for the landline. Cellular carriers are 3, all are GSM//GPRS/EDGE/HSDPA/HSDPA+ (in the 900 and 1800 MHz GSM bands) all handsets work on all networks, they all share the same spectrum. WiMAX is available as well as far as I remember - two players with 80MHz bands and 5 with 40MHz bands all between 2.1 and 2.3 GHz. Balkans for the most part have a very good internet, cable and cellular service, it is the US that $uck$ and is ridiculously expensive. My cellular carrier also offers SIP (yes, they do not advertising it, and most people would not know what it is, even if they find it on their site, but for the $3 more per month, I can make free calls. Oh, and yes, all inbound calls and sms are free.

    If you read the posting that asserted that "GSM is superior", the author started out by saying "regardless of the technical merits", which makes it very clear that he's not saying that the standard itself is superior. He's saying that because GSM is much much more widely adopted than CDMA, it makes it better for the user, because you can actually use it almost everywhere (and in general, you get more choice of carriers in places that have choices.)

    CDMA's radio technology may have been better than GSM's, for the 2G/2.5G/3G versions, though everybody's now heading to LTE for 4G, but GSM's technically hokey authentication system was at least designed so that you could use SIM cards from different carriers in different phones.

    Well, if that were to happen, and Sprint hasn't said it would, but if it were, your phone would continue to work fine for calls and 3G data. I agree though that this is a little awkward....I was going to be upgrading my phone soon, but now I think I'll be waiting longer to see what happens with LTE models rather than another WiMax one as WiMax buildouts seem to have stalled, and I'll want better network coverage for 4G with my next phone.

    I've got a Sprint 3G/4G modem (Sierra U250) for my vehicle's laptop, provided by my employer. The 4G WiMax connection only works if you're really close to a tower, and sitting still. When having a good connection, it gets usually around 6-10Mbps download speed. Not too bad, but I have to run a mobile app that does GPS tracking in real time, and the WiMax will not switch gracefully for tower to tower handoffs. It kills the connection and you must redial to re-establish. I disabled 4G and am running it in 3G mode only to maintain a much more constant connection. It's a shame that it can't cleanly switch from tower to tower in 4G mode as we drive around the city.

    The current problem with WiMax is even though Sprint owns 54% of Clearwire it has no control or board access and they have to pay Clear for Wimax access so they're rolling out LTE on there own 1900MHz spectrum that the current 3g CDMA network runs on which they are moving to 800Mhz as they kill iDen this will greatly expand useable LTE spectrum/speed/coverage with a possible future 800MHz LTE rollout. They are also rolling out EVDO Rev. B as they do there massive network vision upgrade while upgrading to LTE. This is enables 14.7Mbit/s over the 3g network and based on the webcast it's implied most if not all smartphones launched in 2011 support Rev B and will be able to take advantage of it when it goes online. The 3g upgrade will be on the fly and users should be able to take advantage as soon as a tower is upgraded/replaced they won't have to wait for the LTE to be turned on to enjoy the Rev B speeds

    As far Lightsquared is concerned the deal isn't actually apart of the current LTE roll out it's viewed as way to expand useable spectrum via 1.5GHz and on top of that they get paid to use it by Lightsquared in-exchange for access to Sprints network. This turns it into a income generating deal vs an expense which the current Clearwire wimax deal is. The entire fcc/gps issue is rather convoluted as it's been in planning and being worked on for over 8years now.

    As for Clearwire Sprint said they're still in direct talks with Clearwire about WiMax and the future LTE network they want to roll out but it's third behind there own 1.8GHz/800MHz CDMA/LTE network and Lightsquareds future LTE network also If clearwire fails Sprint gets first bidder rights to buy it if I'm not mistaken.
