In-Home Wireless Vs. Mobile Broadband

mklickman writes "I've been hearing more and more about mobile broadband offered by the big wireless phone providers, and for the first time came to ask myself how it compares to using a wireless router. Since my wife and I both have laptops, and we're out a lot, would it be wise and/or worth it to do away with the standard cable-modem-plus-router setup and switch over to mobile broadband with (for example) AT&T or Sprint? I'm not really concerned about the cost of the PC cards themselves; they're not much more expensive than a decent router. Also, the cost of the wireless service per month is only (roughly) ten dollars more than my current ISP is charging me. Is it a good idea?"

  1. How much do you download? by DuncanE · · Score: 5, Informative

    My experience... at lease here in Australia... is that Mobile broadband works very well (remember much of our country is unpopulated desert).

    May lower class people use it to get broadband at the place they rent. They dont have to involve the landlord to get an cables installed and can take it with them when they move elsewhere.

    The big killer is that here is Oz mobile broadband typically comes with transfer limits in the order of 1 - 4 GBs per month. After that it gets very pricey.

    So assuming its the same in the US... I would only go mobile broadband if you dont plan on downloading movies/tv shows etc over the connection.

      My experience... at lease here in Australia... is that Mobile broadband works very well (remember much of our country is unpopulated desert).

      Additionally, there are pretty terrible contracts for mobile broadband (telstra is asking for 24 months last time i checked), so early adopters are once again subsidising later (smarter) takers. Rental properties can easily get ADSL connected without the landlord needing to know about it, because no modifications need to be done on the property.

      Mobile broadband, in my opinion, is something that only makes sense if you need it for your business. When it comes to personal/recreational use, such as on holiday or something to check emails and whatever, it might be easier to plug (or bluetooth) your laptop into your 3G mobile and surf the net that way, or just check into a hotel or cafe with wifi. That's what I have done up until now and, basically, it doesn't cost me $500+ extra per year to do it, in contrast to the mobile broadband.

      I suspect the demand for mobile broadband in Australia has not been as big as was hoped. Actually I am still at a bit of a loss why they are rolling it out when the alternatives are so cheap and so adequate at this point. It doesn't make financial and practical sense to me unless it's a tax deductible thing and you are making money from it in excess of the cost of ownership.

      It's not just gaming either - web surfing is much faster over ADSL than 3G. While you can get pretty good download speeds out of 3G, the latency means it takes a while to build up to the full transfer rate (TCP slow start). Most web pages don't have content large enough that you'll get to full speed, so the browsing experience feels more like "good dialup" than it does "mobile broadband".

      You could also consider getting a phone with internet access that allows "tethering" (at least, I think that's what the kids are calling it these days) so you can access the internet using your laptop via the phone's 3G data service. At home (in .au) I have ADSL2+ in my apartment and 500 mB/month via 3's "X Series" package. It costs me an extra $20/mo but means I do have internet access on the go without the expense of a separate mobile broadband plan. Using your phone for it also means you can have basic internet access even if you don't have your notebook with you, which can be handy.

  2. Wirless and/or Mobile BB by ghostpirate_jay · · Score: 5, Insightful

    I work for a public sector org in the UK, and we have a community team of around 30 users, each with laptops running 3G data cards to give them access to our network (via VPN) when out doing what they do. This also allows them to work from home or wherever they choose - and allowed us to free up space in their offices by removing terminals. However, we quickly encountered problems with the mobile broadband connections having signal problems; various users complained about no signal at home or in certain areas of a city, or worse, in the office. I made the decision to put in wirless access points in each of the three team offices, and set up the laptops to use these instead of the mobile broadband when the connection was found. We also set up a separate VPN that didn't dial out on the mobile broadband, that they could tie into their own wireless conncections at home - this approach was a resounding success. So to summarise...I'd use both! You have to ask yourself if you are going to be using your laptop away from home enough to justify the mobile broadband option - if your staying at home, you can't beat using a wireless set up.

  3. Don't by johnjaydk · · Score: 5, Insightful
    No. It's not a good idea.

    First of all the announced throughput is a best case figure. You'll never see it in actual use. Inside steel and concrete buildings you're certainly not going to see those figures. It all depends on the radio reception. The speed also depends (at lest with GPRS over UMTS and EDGE/GSM) on the number of active users on a particular cell.

    Second, even if the throughput is ok the latency really sucks. It takes a while from you request a web page and until it actually starts flowing in. I've worked on this tech for a number of years and it's not nearly as good as marketing wants you to believe.

      Another thing to consider is that I have found that my supplier (T-Mobile in UK, using GPRS) has an intercepting proxy server; they strip out 'unnecessary' parts of HTML pages, and re-compress any JPEG images at the highest most lossy (eg 50k->10k) setting in order to make it seem faster which also loses EXIF data.

      I don't know if this is only for GPRS or if it affects their 'broadband' services also but it seems to be limited to port 80 so its not too difficult to get around with a proxy but it can be annoying..

    1. You are lucky to see speeds like that. I have the same combination and I see speeds under 128Kbit under realistic conditions in the UK. It is very rare for the speed to go above 256K. In fact the only places I have seen it higher are non-UK networks.

    2. The question of DSL vs 3G has a very simple answer. The answer is a question in itself - do you have a home server and where does your traffic come from?

    If your mail, media, etc is stored on a machine at home, 3G is shooting yourself in the foot. Your traffic ends up going all the way down to the GGSN at the mobile operator and than all the way back up to your kit at home (often through the narrow side of a cable or DSL). If all of your stuff is sitting in a colo somewhere or is on your laptop and you have good 3G coverage, than 3G can compete with DSL for the time being.

    This is a definitely "for the time being" case because as more and more devices in the home become networked a device whose traffic has to travel across half of the country to connect to the rest of the kit becomes a white elephant.

  5. Depends... by retro128 · · Score: 4, Informative

    It depends on your Internet habits. Do you do peer to peer? Then forget it. Verizon says they have an "unlimited" plan, but they've been known to whack high usage individuals. Sprint is better about that, but large usage does attract their attention. If you are interested in mobile broadband in the US, those are really your only two choices. The GSM providers (AT&T & T-Mobile) just don't have the bandwidth. So if you want speed, you gotta use a CDMA carrier. I can tell you from personal experience that my Sprint card pulls 1.5mbs in a lot of places. However, it should be noted that speed is completely dependent on how far away you are from the tower (taking into account obstructions) and how many people are on. So, if you're far away from the tower and there's a ton of people in the area using it regularly, that's also a good reason not to get mobile broadband.

    The relative price you mentioned of mobile broadband vs cable confuses me. You are either getting colossally ripped off for cable broadband or you are not pricing unlimited plans for your mobile broadband cards. Normally, unlimited plans are around $50/mo. Get it. Trust me. I've got a friend at Sprint who's got stories of peoples' laptops getting trojaned and winding up with a $2000 bill in the mail for bandwidth overage. And I'm assuming that you and your wife are each getting a separate plan.

    Or let's say you've got an excellent signal and ridiculous speeds at your house, are not a warez monkey, and you want to share a single card between you and your wife. Well, you can get a broadband router which takes PCMCIA mobile broadband cards. I picked this Airlink 101 at Fry's for $80. It's got an Ethernet switch and is an 802.11b/g access point. Only problem is if one of you goes on a trip and takes the card the other will have to steal the neighbors' WiFi.

    On your point of "luck" about the GP's claim of speeds, you missed that he said HSDPA, which is sometimes called "3.5g" it's much faster than 3G, it's just similar enough tech to not warrant considering it a new generation of connectivity.

    Just wanted to clear that up for anyone following this for bandwidth curiosities.

  7. Keep the landline by wikinerd · · Score: 4, Interesting

    I have a landline ADSL with 1 ISP plus HSDPA cellular broadband with all (3) cellular ISPs that operate here. Cellular broadband is not supposed to replace landline broadband, it is simply for when you are out or whenever the landline isn't working. The latency of cellular access is too high compared to landline, the signal indoors is often poor (but you can use signal boosters), and many times even if one day you have signal after a few days you may find that the signal is gone because tower locations change often and not only that but the connection quality is also dependent on how many people connect near your tower. Not only that, but some cellular ISPs do not give you a real IP, or force you to use their proxy server (easily bypassed though) or even force you to use only their own software (also easily bypassed if you flash the firmware of your router or if you use a free OS such as Debian).

    Thus the perfect solution is to have both. If you can't pay for both, then the answer depends on how many hours of the day you are out. If you stay indoors only when you sleep, then certainly cellular boradband is the answer. But if you do stay indoors more than 3-4 hours of your awake life, then you shouldn't easily cancel the landline.

  8. Share the connection! by dsmaher · · Score: 5, Insightful

    I've got Sprint's mobile, and I love it. But then, I'm in a rural area and NOTHING else works. Satellite is a joke - unless you ONLY do web surfing and email. Anything with encryption is PAINFUL (including online banking). With Sprint, I get varying download speeds (I'm getting 860Kb now, but sometimes I get less). Anyway, I've got several computers in the house (I've got at least 2 running full time, plus a laptop). So, I'm SHARING the mobile connection using an EVDO Router (mine's from D-Link, but Linksys makes one, too). I plug the mobile card into the router, and the router provides Wi-Fi and LAN connection to my network of computers. Aside from the obvious cost savings, the difference is that communication between computers on the network is easier and faster, and sharing printers and other devices is possible. Try sharing a printer across the internet - you can do it, but it's not easy. If you have separate cards for each laptop, you might as well be in different countries. Communication between computers on Mobile broadband works the same between computers whether they're 6 feet or 600 miles apart.
