Beyond 3G — Practical Cellular Internet Access 116

PreacherTom writes "For years 3G, or 'third generation,' denoted some future wireless utopia where voice, data, and video would all merge into a wondrous amalgam, marked by snazzy phones that do everything perfectly — and fast. There is indeed a new wireless utopia, and again, it's about merging voice, data, and all the other stuff at even faster speeds. It is known as High-Speed Downlink Packet Access, or HSDPA, and it has started appearing on wireless networks operated by companies such as Vodaphone in Europe and Cingular Wireless in the U.S. Meanwhile, South Korea's Samsung has even started building HSDPA-ready phones. The technology promises wireless speeds as high as 3.6 Mbps but in practice will be much slower than that — fast enough, though, to make wirelessly surfing the Web and downloading music and video well worth the effort."

    The article seems information-free, largely hype with no substance, by someone who appears to have limited understanding of the issues. Even Vodafone is spelt incorrectly.

    HSDPA is actually just an improved version of W-CDMA, the underlying air-interface standard used by the UMTS and FOMA 3G standards. It's an incremental improvement on W-CDMA, it brings more bandwidth but more importantly it brings lower (sub-100ms round-trip ping) latency. HSUPA is the "next step" from HSDPA (HSDPA concentrates on the downlink, HSUPA combines with HSDPA and improves the uplink) and brings better-than-DSL latency to UMTS.

    There's nothing that revolutionary about the whole thing. It's still essentially "3G" (which is mostly a marketing phrase anyway) mobile phone technology. Bandwidth is still limited enough that you'll not see operators marketing it as a true alternative to DSL in the same way as, say, WiMax will be.

    The article itself seems a little wierd. It's as if someone just found out about SMS text messaging and is enthused about it. HSDPA isn't new, it's been part of Cingular's UMTS roll-out for the two years or so they've been playing with UMTS. Nor is it significantly better or worse than EVDO revision A, which is being rolled out by Sprint at the moment (though there are advantages in the fact that HSDPA is generally implemented with UMTS at the upper levels, rather than the AMPS-derived upper-level protocols that IS-95/IS-2000 networks like Sprint's use.)

I've always found it surprising roaming charges haven't dropped given the ease with which this can be done.

    • Hey, guess what - the rest of Europe is "abroad", in much the same was as the US or any other country.

      The roaming charges stem from increased competition in the domestic markets pruning the monies raised from a finite number of local subscribers.

      FWIW, oart of the reason for HSDPA is to lower latency on W-CDMA networks (by optimizing the downlink.) With HSDPA, latency on a UMTS network is about 100ms for a round-trip ping. Add HSUPA (which improves the uplink), and the latency drops to around 10ms.

    "HSDPA" doesn't sound whizzbangy, but is useless and hard to pronounce. Definitely a low qualifier.
  • People who blather on about "Downloading songs," "Surfing the Internet" and "Watching Video" on cellphones (or other similar sized devices) are either ignorant of the interface obstacles, or heavily invested in Wireless stock. It's not the lack of speed that prevents people from doing these activites on their PDA/Phone, because people on dial-up (yes, there are millions of folks in the US who are still in that world) do all of them on their PCs. The videos may just be clips, but folks are downloading them.

    • Or a USB or Ethernet jack to attach to a laptop.
      • or get a really long extension cord and put a WiMax card in your desktop.

        But that still doesn't answer the main question, which is how usable is this as a mobile technology? If you're talking about sitting in Starbucks or at the bookstore and using your laptop, then why not use the (free?) WiFi there? Maybe if you're on the train, you might have your laptop and the need for highspeed (some of the trains here have WiFi), but how many people do you know (outside the /. crowd) who take their laptop with them e
  • The problem with GPRS, in the UK at least is the cost. It's ridiculously expensive for non-business contracts to be used to check even your email, let alone streaming music and video.

    I would love to have my phone used for sending and receiving email, browsing the web, checking my RSS feeds, and using IM, but I simply can't justify the cost.
  • PCs have at least XGA, 1024*768 pixels *24 color bits *30FPS = over 550Mbps [google.com] just for video display (the vast majority of needed bandwidth). Even compressing that by 20x is over 25Mbps. But mobile phones' much smaller screens are probably quite good looking with QVGA, 320*240, 55Mbps [google.com], perhaps compressible to 5Mbps or less, maybe 3Mbps.

    500Kbps compressed audio will also complement the small, detailed screen with the (relatively) hifi audio that is the priority for mobile media.

    Which puts HSDPA's 3.6Mbps max r
    • Your estimates of bandwidth are way, way, way, way, way off.

      Don't forget compression.

      AT&T is delivering 3 SD TV streams, and 1 1080p HDTV stream, over a 19 Mbps connection.
      With a modern codec you can do full screen XGA video (less bandwidth than 720p) in 6 Mbit/s. Apple does 720p Quicktime Trailers at 6 Mbit/s.

      For comparison's sake, they do 1080p trailers at 9 Mbit/s, and 480p at under 2 Mbit/s.

      Similarly 500 Kbps is WAY over kill. Most people say that stereo MP3's compressed at 384 Kbps are indistinguis
      • What do you mean, "don't forget compression"? In my post, I mentioned compression at every turn - even 20x compression for the "baseline" XGA. And again in the mobile scenario. And again, explicitly, for the audio. Which I can very much tell is better at 500Kbps than at 384Kbps, especially in the headphones that mobile devices prioritize.

        I'm not sure which post you're replying to. Because the mobile screen I detailed is QVGA, not QXGA.

        I have not seen/heard the AT&T streaming you mention. But since it's
        • No, seriously, I don't know why you are arguing.

          Please re-read my post.

          The bitrates you specify do not come close to the bitrates currently being acheived via modern video compression (H.264). AT&T's Project Lightspeed is a drop-in cable replacement service, and is currently operating IPTV over Fiber-To-The-Node, with VDSL providing the last leg, at a total of 25 Mbit/sec per residence.

          The quality is supposedly pretty good; though I doubt it is as good as a conventional cable provider.

          And the "QXGA" I w
    • Also, as a follow up to my previous content, you do not need to match your display's resolution bit-for-bit. When was the last time you watched "native resolution" footage on your PC? 3D rendered content via your graphics card does not count ;-)
  • I wish they would actually take a technology and push it all the way out first before jumping on the next thing. Get coverage everywhere--even small towns. The way it is now, someone intros something new, it gets rolled out to the large cities because they have more people. Then something new comes along, and the first product is abandoned and the new one is rolled out to the large cities. The people in smaller population centers end up with nothing despite all the promises of great coverage.

  • How much will the service cost though? If I remember right, Blackberries use 3G right? Which happens to cost around $60 to $80 USD monthly, correct? So I would have to assume that this new "HSDPA" (advice to marketing: don't use confusing naming conventions, lest people be tongue-tied when they try to order it) would either cost over $80 USD monthly, or the current network would have to drop the price of the monthly bill - why pay for the old one if the new one is faster AND costs the same?

  • I was just asking about this in a Tokyo shop last week. NTT DoCoMo now has a phone out (they made it look cyber-like but it is uglier than their other nice looking phones) as well as a pcmcia version for hsdpa (3.6 Mbps). News about it (from May) here [cnet.com].

    I was told that you need a separate provider (I have NiftyServe, which I use to get a login account on my home fiber connection from Tokyo Gas, which I can use apparently). There are 64K, 384K and 3.6M (2 models) but I am still trying to figure out just what

  • WiMAX [wikipedia.org] is currenty under development in our laboratories - it's like WiFi access everywhere.
    Believe me, it's worth some patience.

  • Due to different technologies, it is *much* easier to overlay EVDO on CDMA2000 systems than it is to overlay UMTS on GSM systems. That is why in the US all the CDMA2000 carriers (Verizon, Alltell, sprint?) are adding 3G (>1megabit) capable services quickly (broadband access, video clips). In fact, Verizon broadband is readily available in most metropolitan areas (my business friends love it). GSM carriers will be slower, with only Cingular having enough radio spectrum to deploy UMTS (W-CDMA, different fr

      Right, keep dreaming. Even countries like Bulgaria have HSDPA [cellular-news.com] (sometimes called G3.5). Note the date - Sept. 2005.
    • EVDO is one form of CDMA2000, it's not something you add as such.

      More importantly though, the issue with W-CDMA isn't that it's different technology, it's that it requires 5MHz of spectrum in each direction, and existing PCS operators frequently only have 5MHz of spectrum to begin with in many areas of the country. This is a temporary disadvantage, as for the most part the intention has been to use new spectrum promised by various governments. The designers of UMTS largely relied upon those promises, and

  • Hello! Here in Portugal we have about 1 Million HSDPA users. Many people are connected using 1.8 Mbps cards from HUAWEI and now the GSM/3G Providers are making the switch to 3.6 Mbps USB Dongles. The service costs 39,90 Euro and includes a 5 Gb download limit. Currently there's a promotion of unlimited access until 31 December 2006 (which will probably be extended). Since I'm always on the run, and I noticed how stable the system is, I dropped my ADSL line at home. Happy user am I.
  • Yes, you read that right - there only one HSDPA-capable phone [phonescoop.com] available in the US (from Cingular).
  • I am a proud owner of a 3.5G card (HSDPA) and I have some notes about its usability.

    I live in Portugal, and not even 3G is accessible in every zone. Lately the cell companies have been improving the access points, and at least I can now connect using 3G in almost everywhere (even in the mountains).

    Some things good about this tech:

    * I have network access everywhere in my country, in those places I have cellular phones (that means 90+% of the country). It ranges from plain GPRS (64kbit),UMTS (384kbit) and HSD
  • For many years I had mostly ignored CDMA systems and worked primarily on TDMA systems like GSM+GPRS+EGPRS, IS-136, PDC, DECT, PHS and PDC. I were of the impresseion that CDMA systems like IS-95, CDMA2000 and WCDMA R99+HSDPA were overhyped but I assumed they deep down had some merit despite the hype.

    How dissapointing to figure out that the guys who worked on these standards had largely missed out on 10 years of development in GSM so now we are stuck with something that is a solution to yesterdays problems

  • ...measured right now is 2457.6kbps on Sprint's EVDO network while sitting in my apartment. I use an HTC PPC6700. My favorite speed record is arguably the 1228.8kbps I can pull down in rural Franklin County, Kansas. I am quite impressed with it. Until some service that is way cooler and some device that is way more powerful than the 6700 come out, I have little to complain about.

    However, Sprint is retarded when it comes to PAM (phone as modem) use. If you have the cheap plan and try to use your phone a
