Difference between GPRS, Edge, 3G and HSDPA

26 01 2010

GPRS, Edge, 3G and HSDPA what’s the difference?

Thought i’d update this article to include a little bit about 3.75G, see below.  Obviously 4G is taking it’s time!!

24/06/2013 – I’ve written a new article about GPRS, 3G and 4G that’s a little more up to date right here

So Mobile networks are at last here and we use them every day as part of our normal business and personal lives.  However many people I talk to still get confused with the differences between them.  IT’s even more prevalent in the Rugged PDA world because due to the stability of the devices a lot of them tend to lag their “Consumer” equivalents in the GPRS technology they use.  Below is a quick overview of some of the most important things you need to know about GPRS.

And in the beginning…

They made GSM modems.  Does anyone remember the times we used those horrible 56K modems to connect your desktop to the internet by plugging it into your phone line?  Well at first that’s how they did it with mobile phones in a roughly similar way too!  Very low data rates of 10kbps and also the fact that you paid for the time you used the service were the main down points of this.

Then came 2G

However with the take up on mobile phones rapidly increasing we saw the switch to digital networks which allowed for better call quality and the SMS service.  We started to see the potential for data to be sent using them.  2G was born in the form of GPRS.  This allowed data to be sent over a network that was a lot more optimised for data communication.

GPRS was and still is a little bit slow at no more than about 114kbps and unless you have a class 3 device, it can’t support sending data at the same time as a GSM voice call is in session.  However this is more than enough for many people’s needs, even today and to add weight to that, the first iPhone was a GPRS device.

Edge a stop-gap

3G was on the way but we saw one more incremental step before this was rolled out.  Edge, eGPRS or 2.5G was a technology that gave us 3 fold better data rates with typical 400kbps being heralded by Cingular in the USA by using better coding methods than GPRS.  However 120-200kbps is probably more realistic.

Finally 3G Arrives

Finally full 3G was released and it not only gave us more reliable faster data rates of up to 384kbps but it’s based upon a far better platform that allows synchronous voice and data usage.  With 3G browsing the web performing more media intensive data work became a reality and in some cases still rivals some broadband connections we have in out homes.

HSDPA and 3.5G, 3.75, 4G and beyond

Currently HSDPA is the standard for most mobile phones.  Running at 1.3mbps it rivals most broadband connections and networks are being upgraded across the UK to run at speeds of up to 7.2mbps, coined 4G.

We’re now even starting to see our first 4G devices in the HTC 4G MAX, although we’re actually seeing a trend in 3.75G HSUPA devices being released at the moment, which are actually HSDPA devices but with improved upload speeds too.

Added (19/10/11) HSPA is it a spelling mistake!

Well no and HSPA and also evolved HSPA or HSPA+ are all new acronyms in the 3G world.  I’m not going to get technical here, but these protocols are basically the next step in the mobile networks upgrade path.  HSPA (Downlaod) and HSUPA (Upload) are pretty much implemented now and devices taking advantage of this can now theoretically reach speeds of 14MBPs on the downlink and 6MBPS up, some networks in the world have reported even more than this.  HSPA+ further enhances this up to 80 & 22 MBPS which is now surpassing broadband speeds.

With 3.5G, 3.75G, 4G and now HSPA we really now have no excuse to be connected to the Internet where-ever we go and its only a matter of time before the PDA or mobile phone truly becomes the data tool of choice as our lives become ever mobile.

if you still need some help then give us a call at Rugged and Mobile and we’ll only be too happy to help you choose the right device for you.

Where does EDGE fit in to this? You mention it in the title…

20 12 2010
ruggedandmobile

Edge is sometimes referred to as eGPRS or 2.5G and its in the part called “Edge a stop-gap” above.

Basically you find that Edge is still the most common data technology in Rugged PDA’s and it is usually implemented so that dual data and voice calls can occur at the same time.

The first Iphone was a GPRS device what about the new Iphone 4?

6 06 2011
ruggedandmobile

The original iphone was edge based (2.5G), the iPhone 3G, was 3G and the iPHone 4 is HSDPA (3.5G). HSUPA (3.75G) is the fastest usuable speed that exists right now but don;t forget that it depends on the network you are using and the availability of the data speed in the first place.

Could you pls tell me if my cell phone (evertek fd10) (which is gprs edge phone) can work with 3G network? (maybe the Q is stupid, but I do not know much about this). Thnx. Kristina

10 08 2011
ruggedandmobile

Hi Kristina

If your phone is only an edge (2.5G) then thats all it will ever do, regardless of the network coverage and capability. To get 3G or aboave you need to get a phone with 3G, HSDPA or HSUPA (3, 3.5, 3.75G).

Great blog…. and very useful…but really in the begining… I mean back in the very beginning …like 1985/86/87….I had a Vodafone mobile (Motorola and then Nokia) to which I attached a CDLC modem and to that a “PDA” (later a Psion Organiser/Psion Organiser II) to access individual BBS, MicroNet & later JANet. With no http, tools were the big problem…but there was finger, gopher, and email. But it didn’t fit the pocket very well… and if you really wanted to use it for more than an hour, you’d probalby flatten your car battery…but I could keep a database in my office, and interogate it on the move.. (well no, I had to park up)….but rugged…oh yes very rugged….just don’t dangle it by the cables….:-)

broadband is working on 2G or not

17 08 2011
ruggedandmobile

Hi Amritpal

This post was about mobile WAN (Wide area network) technology which connects mobile phones to the internet via the GSM or CDMA phone network. It runs over your Airtel or Hutch mobile network and 2G is GPRS running at no more than about 40-50KBps. Broadband is usually the term we use for cables going into your home or office. In the UK we have ADSL (BT) or Cable (Virgin Media). Broadband as a term is also a way people refer to their network speeds. You need HSDPA (3.5G) or above to really start getting up to broadband level speeds.

I’m not sure what speeds your broadband is in India, but in the UK Virgin is topping 50MBps, whilst ADSL tends to currently top out at 20MBPs. HSDPA is theoretically up to 7MBPs but I don’t think the mobile networks in the UK support anything like that.

Hope that helps.

Hi, thank you for this nice article.
I have a question: my galaxy tab often keeps switching between hsdpa and edge, sometimes hooking one or the other.
Why?

17 08 2011
ruggedandmobile

Hi Marco

Thats because, despite the Galaxy being capable of higher 3G speeds (HSUPA or HSDPA i can;t remember!), it depends on the network you are using and the capability of the GSM mast you aere using. This is why in a city you’ll often get 3G or HSDPA, but where the population thins out, the masts have never been upgraded from eGPRS. Your Galaxy will hook up to whatever it has available from 2G up to 3.75G.

No its certainly not rugged, but its an interesting case and concept. Otterboxes are great for keeping smartphones clean of scratches and they do offer added protection but they are not MIL or IP rated and are far from what we would call rugged. To be truly rugged requires a lot more than a fancy case.

Great article! I had a 3G phone connected with T-Mobile 3G sim card. After my phone broke I went on the hunt for a reasonable replacement. Not needing internet on a regular bases the pay as you go option is my basis for not upgrading to an iphone or go on contract. The replacement phone I settled for has all the bells and whistles but is GPRS/EDGE and thanks to your article I saved myself some hard earned money! As I told my friend, “There is no need buying a phone that has functions you don’t understand or can’t use.”. Thanks to your article, I took my on advice! Cheers!

i have a 3.5g phone using in a 3g supporting area but without a 3g activated sim.will i have any advantage while browsing or downloading?

11 10 2011
ruggedandmobile

The type of network coverage you will actually experience depends on all 3 Prasoon. Firstly you will only ever get the speeds of the mobile network masts you are connected to. If you;rein a GPRS area then thats all you’ll get regardless of how fast your PDA is. Secondly the PDA of course dictates the speed too, if its an Edge (2.5G) device then even if you;re in the centre of Bangalore where HSDPA is prevalent everywhere, you will still only get a 2.5G speed. I’m not sure about the SIM cards. I know you used to be able to get GOPRS locked SIM cards in the UK, I haven;t come across them for a while though. The SIM card can restrict your speed though and I beleive this was done by the mobile operator detecting certain SIM cards and restricting this at their end. This is how mobile opertaors restrict/curb high data users.

After reading this blog article back in August, I started keeping track of my download/upload speeds using the dslreports website, an HTC Touch Diamond and a Vodafone (Ireland) account. In the heart of the Pyrenees with SFR (part of the Vodafone group) I was getting GPRS at 26kbps, Edge at about 40kbps and HSDPA at between 220 & 240kbps. In my home in Ireland, where I have my own cell I get about 2500kbps on HSDPA and if I wonder into the village it drops to around 1000kbps or so showing the 3G logo.

17 10 2011
ruggedandmobile

Cheers David

These seem very very typical of GPRS/3G speeds albeit at the top end and quite impressive to me if they’re actual speeds obtained. You still hardlly get 2MB through your “UP TO” speeds on broadband connections so I am quite impressed! Don’t forget that speeds can also be affected by a lot of other thigns too like number of users, how the mobile operators throttle speeds, what device and SIM you have and also GPRS especially can be implemented quite differently on devices, especially class 12 ones.

Thanks… A very informative description.
I’d just like to know more about the cost differences between 3G and GPRS/EDGE. My phone is 3G compatible and can either be set on GSM, UMTS or dual mode. Do you know which one will be cheaper? I am not too worried about the battery life.

Hi Melissa

You can think of all of these as roads. 2G or GPRS is a narrow country lane, 2.5G (Edge) maybe a B-Road, 3G an A or main road and all the way up to HSUPA which is like a 5 lane motorway.

Think of the traffic going down these roads and then the toll booths they would have on them. The Motoroway will take far more money as there are probably 10-15 booths on the toll with far more traffic on the road. Its the same with GPRS. You will only ever get a low KBPS speed down these so effectively you can’t physically spend the same amount of money you can on a 3G or HSUPA enabled phone.

Sometimes we wonder how these mobile operators give you a smartphone capable of doing 7MBPS but only give you 500MB per month, you do the maths!

Hope to have helped

8 12 2011
ruggedandmobile

Hi Marcus

I don’t know thw phone but i do know that it sounds like it has what’s called a “dual radio”. This means it will work on GSM and UMTS based networks. GSM is what Europe and parts of Africa use (among others) and UMTS is what Asia use. The USA is half and hald, AT&T is a GSM Netwok, Verizon and Sprint are UMTS. I htink I got that the right way round, but you get the picture!

Basically your phone can work anywhere!

R&M this is really useful – could you give rough dates as to when each step happened or will happen, i know it would be very rough but the trend is of interest. Thanks Gordo

Hi Gordon

Its a tricky one to assess really. The reason is there have been 4G handsets for years but the network in the UK has never been upgraded to make use of them. However things are changing now and fast. We have just seen the first 3.9 (HSPA+) handset released in the Honeywell Dolphin 7800 and we’ll need t upgrade the blog to deal with this!

In the states they’re rolling out 4G aggressively now on the Sprint and Verizon networks and the next iPhone is rumoured to be full 4G too so I think next year will see the UK probably lagging but definitely improving.

Hope that helps!

6 01 2012
gordon dickson

Thanks but i am interested in the history & trend, if i took the view of date when realistic UK adoption took/will take place (just guessing) do you think it would it look like this?

GSM 2001
GPRS 2006
3G 2010
3.5G2011
3.75G 2012
4G 2013

see what i am getting at? – could you correct these dates in your opnion, I kow its very rough i still use plenty of GPRS but i am trying to show the aceleration effect over a roughly decade. Thanks

6 01 2012
David Marshall

Yes that would be interesting. I lived through it all, used it all. But it also, all went by so fast. A review of the technology timeline, introduction, uptake, even commercial adoption would be interesting to study. No doubt there are some commercial studies out there, but they’ll be a $1500 if not more.

Well I know 4G is being tested in London right now and its pulling 80MBPS from what someone at O2 told me. 4G is due to launch in 2013 in the UK and its brand new technology so should be far more stable and far quicker.

4G will also take ver the old TV signal frquencies to help it reach rural areas far bett than 3.xG does now.

There’s actually a great link i found this morning about the dates that should help far more than i can here, it has an in depth look at the agreements and country take up of GSM to HSDPA.

Brilliant…I’d forgotten how many steps there had been…. I recall back in about 2002, you could access my wap.blog by typing “cafe” (2233) on your wap enabled phone… think the system went belly-up around 2005.

Nice simple timeline on gsm.org though.

To My knowldedge the iPhone 4 is an HSDPA phone with 3.5G capability. The 3G used 3G!, and the iPhone 2 used GPRS or edge to be precise.

I have a question for you: At this time, I have a Blackberry thru AT&T. I’m not in a two year contract anymore and loving it. However, I do want a Droid. If I go to an AT&T store and play with the phones, find one I like and buy it from say, Ebay, when I put my SIM card in will it automatically know that I’m not on EDGE any longer? I’d actually like to get the T-Mobile G2 and drop my SIM card in, but I don’t know if it will automatically recognize to run on 3G. I really DON’T want to have another 2 year contract if I can avoid it, but I do want my new phone to run faster than EDGE.

Thanks for sharing your knowledge with all of us!

9 05 2012
ruggedandmobile

Hi Bonnie, We’re UK based so my US knowledge must be taken with a pinch of salt. Firstly, AT&T and T-Mobile are different networks so my guess is that you might not be able to just use the new SIM. Secondly I know that Blackberry SIMs can be a pain to use in other phones as they use different gateways etc for their data. Networks like to keep their iPhone and BB users separate.

Why don;t you just buy a SIM only deal. In the UK you can get rolling monthly or PAYG SIMS that gove you a really good deal and TMobile tend to lead the way when it comes to flexibility over here.

14 05 2012
ruggedandmobile

TRhat really depends on which “experia” you have. The tend to all be at least HSDPA (3.5G). If you’re not getting the sopeed you think you should be then it’s probably down to a few things. The network coverage, you might have a 3G phone but are you in a 3G area? Throttling at the network, IE do you have the right data plan or are you busting it and getting throttled back. Check the SIM card is a 3G one, although rarer these days there are still some SIM cards that only allow GPRS whatever device you put them in.

Yes 4G is being trialled here in the UK right now and the speeds are alarming, like 80MBPS, the stad though states 100MBPS. However the proof will be in the implementation and how the networks delievr the services. 100MBPS is no good if there are 1000 people all trying to use it in one go!! 3G is the most prevalent technology now but GPRS still has it’s advantages in the RUgged market especially.

I think you should rather be writing Mb/s instead of MBPs. MB is not equal to Mb. My question is are there any real 3.75G phones out there? Cuz I think in order to experience such speed u will need a 3.75 device. Will 3.5G devices e able to operate at 3.75G speeds? I don’t think so. Airtel in Ghana is even saying they have 3.75G providing up to 21MB/S. That translates to 164mb/s and that’s even faster than 4G networks out there. Are they making a mistake or I’m missing something?

18 06 2012
ruggedandmobile

Hi Kwame I guess strictly speaking mb is a Mega BITand MB is a megabyte so i’ll take a look at that in the blog. Most phones that have been released in the past year are probably 3.75G or 3.9G but just because they have the chip in them does not mean they will get the download speeds, for 3 main reasons:

1. The network providers network might not be up to that speed or the particular area you happen to be in might be only serving GPRS speeds.
2. The network might have the technoclogy but is throttling it or there is contention for the bandwidth in some way.
3. It also depends on the exact architecture of the chip, OS and phone you have. Some are faster and better than others and this is all about how well the phone deals with traffic itself.

4G should technically give 100MBps, trials have been showing around 80MBps in the UK but in reality no-one really knows how much it’s going to give the end user in the end. 4G in the USA is not true 4G, it’s still based on 3G technology at the meoment.

Hope that helps

18 06 2012
kwame

1. I believe you mean 80mbps and 100mbps because 100MBps(data copy and read rate of most modern hard disk drives) will be 800mbps which is much faster than any internet connection used commercially in the world today, even for wired ones.
2. I asked whether 3.5G modems can operate at 3.75G speeds ruling out network reception and speed, I guess not
3. As far as 4G LTE is concerned HSPA+ is a promising rival. Current 4G LTE systems (not trial) offer around 21- 48mbps

Thanks though

Since I have voice + text messaging plan only (no data), I’ve got Edge (“2.5G”) enabled but not 3G on a Lumia 710. For voice calls and SMS I presume there is little noticeable difference between the two.

9 07 2012
ruggedandmobile

Actually if you’re in a 3G area, then 3G will be significantly faster. Did you ever see the iPhone 3G event and advert that shows how much faster? 2.5G at best is talking 100KBPS, 3G up to roughly 700.

Well I don;t know where you live, but in the UK most of the country is still oblyt covered by 2 or 2.5G. I also explained higher up the benefists of running phones in GPRS only mode. In the rugged world custoemrs still ask for GPRS and not 3G PDA’s for these reasons. Its less and less but we still get reuests and many PDA’s are still available with GPRS.

imeel.anthony@gmail.com

So how does LTE fit into all of this?

22 08 2012
ruggedandmobile

LTE is basically 4G in laymans terms. It’s completely new technology that requires rolling out across the masts and handsets need a new chip to use it. Add to that the nwteork operators also need to have it running as a service. To put LTE into perspective, its supposed to bring 100MBPS speeds to mobile data. What the actual result will be is your guess and mine!

1 09 2012
David Marshall

I thought this little result might be of interest. Generally I use a Nokia Lumia 800 on vodafone.ie. Its OS has just been updated to allow internet sharing, with the Lumia acting as a wifi hotspot utilising it’s data connection.

At home standard 3G/2G reception is pretty poor so I use a Vodafone femtocell over a Vodafone 7Mbit/700Kbit ADSL connection. This provides me with my own 3G cell station and makes sure I always get good voice and data reception around my home, for my phone, using 3G and exploiting the broadband connection to which I already subscribe. I’ve been using for well over a year now and am very happy with it. I reviewed it back in April on my own occasional blog: http://ifeck.com/2012/04/06/suresignal-from-vodafone/

So I’ve just tried the Lumia’s wifi hot spot; easy and effective. As a result, I also tried a speed test using broadbandireland.ie. This normally shows me that my contracted domestic broadband runs to speed at: 7Mbit/700Kbit . Using the phone I got 5.22Mbit/500.2Kbit. Which I thought was pretty good… even so the question is what’s limiting the speed…? Is it the technology in the 3G femtocell or the Nokia Lumia 800. Not that I mind either way… that’s quite an accpetable performance from both products for now.

Keep up the great work

David

Hi James, We’re based in the UK so i’m not 100% sure but what i do know is that India’s mobile network industry is alive and kicking, with most of them offering at least 3G speeds. Wikipedia often have a good summary of a countries mobile networks so perhaps take a peek at that?

Hi Ravindra, what is your phone? It might be that your phone is picking up an Edge signal but not actually capable of Edge or it uses a lower class of Edge that might not be fully data/phone compatible. It’s also dependent on your network and the coverage they give you too

I’m not sure if you’re UK based so I can only go on what I know about my ipad in the UK! You can’t charge it up with GPRS, you either get a data plan or you don’t and as the ipad is a 3G device, it will use 3G wherever it can. Most providers offer 1, 2 10GB plans so there should be a plan that suits you. At the end of the day your ipad will consume the data you ask it to (And then some) so if you;re watching movies or downloading stuff you will use up your data plan quickly, just like with any other device.

hi i went through this site. it is good blog. Actually HSPA is nothing but HSDPA and HSUPA. i had a doubt that in market lot of data cards are available. on some of the cards why they mention HSDPA and on other they mention HSUPA? instead of mentioning separate names why cant they mention it as HSPA?

I’m not subscribed to mobile broadband service and my phone supports 3G and Edge. I only use WiFi for browsing. I notice that my battery’s drain is less when I have Edge set as my fastest connection instead of 3G. My takeaway from this article is that for my voice and SMS usage, Edge should be sufficient.

That’s certainly my experience. I think theoretically 3G will consume about 1,8 times as much of your battery juice than 3G. When I’m staying in locations where there is only 2G reception and I’m not doing much to access the internet the charge in my Nokia Lumia 800 lasts around 3 days; as against half a day if I’m really flogging it. But I have noticed when there are locations with a 2G/3G choice, I do seem to get better “reception” when logged on with 3G; phone calls do seem clearer. Having said that I also use a “lone worker” phone (Sonim 3.2 Sentinel) It only runs 2G… I get great reception in the remotest of places and if I’m not being tracked (so GPRS/Edge always on) I get at least two weeks out of it. And when I really go into battery save mode, with little or no calls or texts, I get close to 3 weeks out of a single charge of battery. There’s no doubt that a well engineered 2G phone can give outstanding performance, but I suspect that most modern 3Gphones offering 2G compatability have probably sacrificed something in reception, call quality and battery life….maybe these guys at ruggedandmobile can tell us more…

Should do, all versions of 3G are backward compatible so your phone will work but it will just be quite slow.

I’m actually a “green leaf” in mobile technology. But I will like to use your platform to improve my understanding of Mobile Technology and possibly be able to inprove that of many others.
How do I know this mobile phone supports or belong the 3G, Edge, Gprs or which category. For instance, I use BlackBerry Curve 9300. Where do I classify it and do I know which of the above named it supports?
I wolud appreciate with respect your response and education.
Thank you.

The spec sheet should tell you, all devices have a downloadable one.
