Mobile Broadband - Built in Modems compared to USB sticks.

[markbishop]

I currently use a Samsung NC10 netbook with a Vodafone 3G USB stick. I'm not sure of the model number but it's the one in black that does 7.2MB/sec where supported. I've been disappointed with the USB stick, because it often shows a much weaker signal than my BlackBerry in the same location (it's also on Vodafone). This isn't just a question of the signal strength monitors differing - the data stick sometimes can't connect at all in situations where I'm able to make and receive calls, send and receive emails and browse the web fine on my Bold 9700.

Someone has told me that reception is generally a lot better with laptops that have built-in 3G data capabilities. Is this a fair comment? And does anyone know whether it is true of the Sony Vaio Z-series models, which is what I will probably buy?

I've also heard it said that Vodafone 3G SIM cards can't be used with some laptops' built-in 3G capabilities. Is this true, and if so, are the Sony Z-series models affected?

Hi Markbishop,

On the question of whether an embedded SIM module offers better reception than a USB modem, I'm afraid this is a case of swings and roundabouts. On the one hand, an embedded SIM does have more power available to it, which can increase reception - a USB device is limited to 5 Volts, and one some laptops and netbooks, even less, which affects the modems ability to function correctly.

On the other hand, if it's not a very powerful laptop or netbook with a poor power supply to start with, then the affect would be negligible - and can also be cancelled out by the fact that there is more interference from the chassis of the computer to block the signal than with an external USB modem.

I guess what I'm trying to say here is that your mileage may vary

With regards to not being able to use a Vodafone SIM - this is usually only the case if the laptop is network-locked. The easiest way to spot these, is if they come pre-bundled with a special offer for one particular network. If, for example, the laptop gives you a free 30 day trial of Mobile Broadband with Orange, then the laptop is almost certainly network-locked to only accept Orange SIM cards. You can request a Network Unlock Code from Orange to undo this, but it may cost you.

I trust this information helps

Think of it as your WIFI, which basicly has an aerial that goes around your laptop, Around the monitor etc. this is the same with a Embedded Module. With the USB modems its just a small Aerial.

I'm now largely decided to get the Z-series Sony Vaio with Everywair built-in 3G as it seems to me that the 3G dongle delivers very much worse signal strength than a BlackBerry and the laptop surely can't be worse. What will I have to do to set it up? I have a conventional Vodafone 3G mobile broadband SIM on a contract that I think gives 3GB a month for about £15.

Hello Markbishop

The first thing you'll need is to make sure there's a connection manager installed on the laptop, (there should be by default). If there isn't then you'll need to download the Vodafone Mobile Connect software (VMC), this will detect your modem and allow you to connect as you would with a USB modem.

You'll need to use the following APN details in the connection settings:

APN: ppbundle.internet
USER: web
PASSWORD: web

Please keep us posted with your progress.

Thanks

Many thanks for this - it doesn't sound too difficult . My new laptop could be a month or two away, but when it arrives I'll let you know how I get on.
