One of the things I love about working with technology, is that every so often you are fortunate enough to have a "hey wow" moment. The software I am writing about is just so useful, and so incredibly easy to set up, that it certainly was the cause of such a moment.

O
ver the last few days, have been playing with a piece of software that allows me to take advantage of the data connection on my phone to the benefit of my Lenovo Thinkpad.

The software is called Walking Hotspot, and is available for free from http://www.walkinghotspot.com.

This  software is for Symbian and Windows Mobile phones. To use it, the phone must support both WiFi, and some sort of data over cellular option. It allows you to set up your phone so that it is your very own walking hotspot. The idea here is that you can use your laptop or any other WiFi capable device to connect to the phone running the hotspot software, so that you can use your phone's Internet connection from another device. The connection can be encrypted using WEP for additional security.

Now it's true that many phones can use Bluetooth to do a similar thing, but there are a few points to note. Firstly, certainly on GSM networks, when you do this you are only connecting with GPRS, and not the faster forms of Internet connectivity such as 3G or HSDPA. Secondly, not all phones offer the modem service. And thirdly, it can be complex for a user to set up.

With Walking Hotspot, you just set up your access point complete with WEP security if you want, bring up the wireless manager on the device from which you want to connect, and establish an ad hoc connection.
The free version is limited in that you can only establish one concurrent connection. The paid version, being distributed through carriers, permits five concurrent connections. But for personal use, the free version is fine.

Obviously, because you will be using the WiFi and data over cellular capabilities of your phone, you're going to use a lot of battery power, and this may be an issue on units that offer poor battery performance.

This software is pure genius and is working brilliantly on my Nokia N82.

When you connect via Bluetooth you are connecting to the available service - GPRS, WCDMA or HSDPA.

The only problem with Bluetooth is not the connection being to GPRS - as I said it is not limited. The problem is that Bluetooth is limited to 115 Kbps over the link to the terminal - your PC. That's the real limit.

Some devices offer Internet Sharing over Bluetooth which is basically PAN. Some other devices offer DUN.

This is interesting info Mauricio, because Vodafone advised me that if you connect using DUN and *99#, you get GPRS, not 3G. But what you say makes perfect sense and would account for the speed.

*99# is used to establish a DUN connection for both GPRS and 3G. it just depends on the capabilities of the handset and the coverage.

I've been playing with Joikuspot for several months now and this was the first product to turn your phone into a "hotspot" - it's good to see a bit of competion in this area! It really is a fantastic concept that it so much better than using a tethered connection or Bluetooth!

Was this one of their engineers or someone at a store? Whoever told you this doesn't have any idea of this works.

It was someone on 777, a good couple of years back now.

Its definatly not gprs when using bluetooth, and somehow I end up with a proper IP on the computer, so I dont know how that works with the phone also needing an IP for its own internet use, but it sure does work just fine using bluetooth.

Cant see how its complex to set up, open bluetooth places, open the phone, open bluetooth connection and put *99# - saved me on many occasions when I have being out and needed data.
