The Power of Embedded 3G

These days, whenever a new device is announced, the first thing I find myself doing is sifting through the small print to learn whether it will be WiFi only or support both WiFi and 3G connectivity. For sure, 3G seems to have an impact on how the public both perceives and discusses the usefulness of that device, so what does the future look like for this often times overlooked feature?

To start with, it’s obviously a cost issue. Adding embedded 3G to any device costs more money. With the iPad, the price jumps by over $100 and for some devices it goes up even more. However, having a 3G embedded device also creates a natural partnership between mobile carriers and tablets, allowing users to signup for a two year service plan and receive subsidized pricing on the tablet – as is the case with the Samsung Galaxy Tab.

What Does 3G Bring to the Table?

Think of it this way – a WiFi only device is no better than a laptop. Yes, you can carry it with you more comfortably, but you’re still stuck looking for WiFi signals wherever you go. That means paying extra fees in airports and hotels, hunting for hotspots when out of town, and having to simultaneously use the phone for any on-the-go communications.

On the other hand 3G allows you to greatly increase productivity. Just having a 3G transceiver embedded in a tablet, you’re immediately more likely to carry your tablet with you everywhere you go. It becomes more like a phone in its 24/7 mobility than a laptop which you must sit down to use in set areas – there’s a big difference.

Beyond simple access, imagine being able to quickly and easily jump onto the Internet and check a video when on the train or look up an important fact or figure in your email. Imagine being able to work on a file and send it while in a cab. These are things you cannot do with WiFi.

Going Beyond Simple Access

Beyond simple Internet access, there are a lot of manufacturers out there pushing the implementation of voice features on devices with embedded 3G. The Galaxy Tab is again a great example. While not available in the US, the European models of the Tab sport voice that can be paired up with Bluetooth to use your Tab like a giant phone.

On one hand it helps the mobile carriers to sell contracts, but one has to wonder if it is a bit of a distraction. You already have a mobile phone most likely – do you need a voice connection to make your tablet useful? I don’t think it’s necessary, but at the same time the fact that it’s possible is yet one more point in favour of 3G connectivity.

Right now, we’re in the transition between 3G and a series of faster, more direct mobile technologies like WiMax and other 4G technologies. Devices that are willing to explore mobile access to the Internet beyond WiFi are going to not only be more useful, but eventually be more desirable (regardless of cost).

How to upgrade Fujitsu T900 or T5010 Tablet PC to embedded 3G

>One of the joys of having so many computers go past my hands is that I get to tinker and tamper with them till I get them right. If there is one scenario I love the most then it would have to be integrating 3G (HSDPA) into a device that does not have it out of the box.

I have been using Fujitsu Tablet PCs as my “main machine” for some time. To name just a few, I’ve owned a T4010 which lead to T4210, T2010, T2020, T4020, T5010 and now T900! So out of all the Tablets I own, and Ultra Mobile PC, I still come back to the Fujitsus as my preferred primary device. The main reason is build quality!

Recently the T900 was announced in Australia and to my distaste I was told that there would not be an embedded 3G SKU in the line-up. This caused me to crack out the screwdriver and hit Google for answers. But with no-one in the world posting anything about embedding 3G inside the T900 (or T5010 – mentioned here as they use the same motherboard inside) I felt duty called!

So here it is:

  1. Open the pack plate on the Fujitsu T5010/T900 and (with the front of the machine oriented to you) look for the top left corner of the unit. You are looking for an elongated bit of PCB.
  2. Unscrew the two black screws which hold down the host-PCB and remove it. (FUJITUSU PART #CP378152-XX)
  3. Now place your new PCB (FUJITUSU PART #CP378152-XX) back in the computer (ensuring the power connector is orientated properly). Place back the 2x black screws
  4. Now insert your modem of choice (Architecture: mini-PCI Express)
  5. Connect the black antenna to U.FL connector labbeled “main” and RED to AUX connector on modem.
  6. Insert a SIM card.
  7. Close the machine up
  8. Boot.
  9. Install the appropriate firmware/driver for your card
  10. Surf!

I know these are over simplified instructions so if you need clarification (or proper detailed instructions) please let me know. Ultimately I wanted to showcase how some hunting and gathering can lead to the right part numbers for the right job! I sourced the Tablet in Australia, the replacement PCB in Germany and the antenna in China! It proves that where there is a will there is always a way an importer! LOL!

Here are some images to assist:

NB. The two antennas on the right are to plug into the modem as per instructions above.
The long white connector is the power connector used to power the PCB.

BOTTOM: non-3G PCB with no SIM slot!
NB. The white connector on the left is for power
and is obviously found on both PCBs
TOP: rear view of SIM slot and full view of mini-PCI express slot
BOTTOM: no mini-PCI express slot or SIM slot! (SAD LITTLE bit of PCB!)
An example of two modems you might use:

I hope this helps at least one person out there. It changed my life radically having 3G embedded in my Tablets; so much so that I would never buy a device without it!
