1) Wi Fi (also Wireless LAN, WLAN):  
The Wi Fi (shortened from Wireless Fidelity) is a technology which permits
communication between devices like between your laptop and the home
wireless router or in the case of PDA between your device and the hospital
hotspot or the ISP hotspot when your are outdoor. It is safe, cheap
(usually free) and also fast. Most of modern hospitals provide free access
to the internet to wireless enabled devices and laptops so this is the
preferred method to access the internet when you are at work (but
sometimes you need to get the password from your hospital IT people).
You don't need to worry about the different versions like 802.11a or
802.11b they all serve the same purpose. WiFi connections get blurred by
obstacles such as walls or other devices and typically in the range of 100
meters so make sure to know where is the closest antenna to the
pediatric section!
The screenshots on the right demonstrates the steps that you take right
after tapping on WLAN in the communication manager + 2 screenshots of
the connections setting where you can find all available hotspots. Because
wifi hotspots are now everywhere make sure to use the free service like
the name of your hospital's network.
Windows Mobile Internet
Connections Simplified
On the right side is the control panel for all connections what's called the
communications manager which can be accessed from the pop up box that
appears when the connection signal icon in the upper tool bar is tapped.
Note that this connection manager is not available in devices older than

From up to down these buttons are:
1- Flight Mode: tapping on this will simply switch off all connections and
making you ready to flight (I prefer to switch this on while in lectures!)
2- Phone: to switch your phone off/on (please remember that powering off
your Windows Mobile device does not switch off your phone signal)
3- Bluetooth: you can switch it on when you need to receive a file from your
pediatric colleague or when you want to connect to another device such as
a head set or the laptop.
4- WLAN: see below 5- Push email: this is a
technology that let us receive emails just like the way we receive SMS, it
needs a subscription to Microsoft servers usually provided by the hospital    
6- Data: see below 7- Ringer: self explanatory 8- Internet sharing: when
your device is connected it can serve as a modem for your laptop!              
9- ActiveSync: opens up the ActiveSync manager to synchronize your device
to your desktop
3) Through the desktop:
When your Windows Mobile is synchronized and connected to your PC (via
cable, infrared, or Blue Tooth) and when your PC is connected to the
internet then consequently your PDA is connected to the internet. This
access is absolutely free (except for the fact that your paying for your
desktop access) and is the highest in terms of speed. Nevertheless, such a
connection may not be so useful because when your desktop is there it is
unlikely that you need your PDA to access the internet. However, there are
certain situations when it could be useful for example when you want to
download big files such as MP3
podcasts to your PDA for later listening. In
such case it's better to use your desktop as a platform to connect your
Windows Mobile device saving the wireless or GPRS bills.
In case you synchronize your device to a computer that is connected to a
network such the hospital network then in that case a window will appear
(See screenshot on the right) asking you to input the username and
password which you should get from your hospital's IT people and in most
cases you can leave the domain field blank unless otherwise specified by
the tech support, please do not save the password because you never
know your device might be lost tomorrow!
2) Mobile Data Service (GPRS):
This is a connection between your mobile GSM SIM card and your mobile
service provider allowing internet connection. So in this case you are using
your mobile connection and not your wireless connection therefore you can
access the internet (provided that your phone signal is good) even when
you are in the sea! Unfortunately this is usually expensive and often is
charged per kilobyte downloaded so you could end up paying several
bucks when log on to a medical website. The speed of connection is much
improved with new technologies such as the HSDPA and UMTS what's
called the 3.5G i.e the new generation of high speed access to mobile
The screenshots on the right demonstrates how to get connected and this
usually done automatically by the device when connection is needed such
as here when I wanted to log on to Yahoo! Go service. The device
detected the 3G network and connected automatically. By default, GPRS
connection is disabled when WLAN is active which is good because Wifi is
always cheaper and faster. That's why you should always look for WLAN
before the device takes you the more expensive GPRS connection.

Getting your PDA device connected to the internet is one of the essential skills that a pediatrician
may need to utilize his/her device to the maximum potential.

In this guide we attempt to give a simplified overview of connection types for a better grasp of the
idea. The official
Windows Mobile website provides an excellent help page about all the details of
Windows Mobile connections, however that could be too lengthy for a busy pediatrician and could
be confusing and therefore this guide serves to simplify matters and to get you introduced to the
task of getting your device online.
There are three means by which you can get your PDA connected to the Internet
