Macs With 3G — More Connectivity, More Problems

narramissic writes "In a recent blog post, Josh Fruhlinger muses on the possibility of 3G radio receivers turning up in future Mac notebooks (as foretold by Apple job postings and the mention of WWAN hardware in Snow Leopard beta releases). 'At first glance,' says Fruhlinger, 'this seems like a reasonably awesome idea.' But will the target market be willing to take on the additional telecom charge? 'And, more to the point,' he says, 'most of us have gotten accustomed to the idea of one Internet connection per household, shared with a wireless router. The latter idea could be covered by a router that connects to the Internet over a 3G connection — something like the MiFi hotspot. It wouldn't surprise me if Apple had such a thing in the pipeline, an Airport station (Airport Mobility?) that didn't need to be plugged into the wall. That would explain the search for 3G experts, anyway.'"

    The submission makes it sound as if there's some big mystery about adding 3G to a laptop that Apple has to solve. But there are other laptop makers out there besides Apple, and almost all of them have been putting 3G in their notebooks for years now. This is a feature that Apple is just behind on, and especially if they want to keep *any* semblance of a business market (and designers and photographers run businesses too - and a lot of them are freelance, working outside), then it's something they really need to catch up on.

    It's a big and obvious mistake to suggest that 3G connectivity is meant to replace wi-fi. 3G connectivity is meant to replace, well, not having any connectivity. Laptops are meant to be portable, and they can go lots of places where wi-fi doesn't exist.

    I can't believe I actually even have to explain this.

      It also seems weird to overlook the fact that:
      • Apple makes mobile phones - is it too much of a stretch to imagine that a job posting related to mobile phone technology would be connected to this?
      • You can connect to the mobile network from OS X already with either a 3G phone that supports bluetooth or a dongle. The OS already has drivers and higher-layer support for these technologies.

      And let's not forget that 3G is a marketing term, not a technology. Do they mean UMTS, HSPA, or LTE? Adding 3G support to a laptop intended for worldwide distribution is likely to cause difficulties as different countries (and even different states in the USA) have different levels of deployment of 3-4G technologies.

      I'm not sure if i'd want a 3G modem built in, it becomes a little harder to get the modem in position for good reception. I'm happier using my HSPDA modem outside of my laptop.
      plus with a pay as you go contract i'm free to use the thing or not as required. There is also an issue of roaming which is quite easy to encounter at which point the data plan goes out the window, and you pay through the nose.

      People are being fooled a little into thinking a mobile internet connection will only work for one computer
      for Linux users its pretty easy to share it /etc/sysctl.conf change this line to net.ipv4.ip_forward=1
      and the following
      ifconfig eth0 192.168.2.1
      iptables -t nat -A POSTROUTING -o ppp0 -s 192.168.2.0/24 -j MASQUERADE
      iptables -t nat -A PREROUTING -i ppp0 -p tcp --dport 3074 -j DNAT --to-destination 192.168.2.254
      iptables -t nat -A PREROUTING -i ppp0 -p udp --dport 88 -j DNAT --to-destination 192.168.2.254
      iptables -t nat -A PREROUTING -i ppp0 -p udp --dport 3074 -j DNAT --to-destination 192.168.2.254
      iptables -t nat -A PREROUTING -i ppp0 -p udp -m multiport --dports 88,3074 -j DNAT --to-destination 192.168.2.254
      iptables -A FORWARD -i ppp0 -d 192.168.2.254 -p tcp --dport 3074 -j ACCEPT
      iptables -A FORWARD -i ppp0 -d 192.168.2.254 -p udp -m multiport --dports 88,3074 -j ACCEPT

      can be run as a script by root.
      all you then need to do is connect eth0 on the to the wan port on a router and set the wan port to a static address of 192.168.2.254 and a gateway of 192.168.2.1 set dns to 192.168.2.1

      and now you have a lan using a 3g interface, incidentally tethering a mobile will use ppp0 so once you can connect with the tethered mobile you can do the same.

      My setup goes one step further chaining a second router to expand the range using tomato firmware and wds +access point mode. Performance wise it seems reasonable, the Eircom adsl link I used before used to top out at about 300kb/s download - 3G hspda modem 222kb/s The relatively small cap of 10gb in 30 days is a bit limiting but I figure the last day of the month will be good to use up whats remaining of the cap.

      If you don't want to tie up a computer sharing there are a number of routers available for about 100 which will do the same job.

      Actually OS X supports some 3G cards OK.

      E.g. here's a guide to install OS X on a Dell Mini 9

      http://i.gizmodo.com/5156903/how-to-hackintosh-a-dell-mini-9-into-the-ultimate-os-x-netbook

      Follow this tutorial to get your mobile broadband working if your Mini 9 has it. Network preferences should recognize it out of the box.

      Now what's interesting about this is that the Dell 5530 wireless card is supported the bundled OS X drivers.

    The problem mostly lies with the way that a lot of companies (more than likely Apple included) would sell them. For example, you would get the laptop for cheap, say $500, but then you would be tied in a 2 year contract with AT&T (or some other cell provider) to get "unlimited" data that really isn't unlimited, costs you a fortune, and theres no other way to buy the laptop.

    Its been happening to cell phones for ages now, and starting to happen with netbooks.

    I think many people are not aware that some ASUS EeePC netbooks already have an HSPA modem (a.k.a. 3.75G) builtin.

    E.g. the model 901 GO sold in Italy or in Germany. They're pretty awesome, you can find them on Ebay and at least the Italian ones were sold by the operator TIM, but they are not locked in any way.

    Apple has done it allready with the iPhone nearly 3 years ago!

    My iPhone 3G prefers the available and configured WiFi connections at home and at work and falls back to 3G everywhere else.

    I'm wondering why it took them so long to add this to their laptop range... it would be very useful to have connectivity everywhere.

    In europe most 3G network operators have been oferring subsidised laptops (mostly 3G enabled netbooks from dell, hp etc) with 3G data contracts for over a year now.

    Unfortunately said contracts usually come with low data caps (like 5 or 10GB) but the point of 3G is to complement WiFi access and not replace it -- meaning that they provide the reassurance that you will be connected anywhere, anytime, but you should plan to download gigs of stuff while on a WiFi network instead.

    No way will Apple force people to buy their laptops through a phone company. Steve Jobs stated that they didn't put WWAN into the MacBook Air because he didn't want customers tied to a single Telco.
