Introduction

So you've got a digital cellular phone and you want to get on the internet?  Well there's a few things you should know before you get started.  First is that each of the carriers require users to pay per minute.  Some allow you to use your voice minutes for both voice and data while other have a separate charge to use their data services.

Ways to Connect to the Phone

Right now you can connect your cellular phone via infrared, serial cable or a CompactFlash Card.  There are pros and cons to using all of these with your Pocket PC, Handheld PC or Palm-size PC.  Here is a summary of the pros and cons to using each:

Connection Type Wireless Wired CompactFlash Slot Speed
Infrared Yes - however you must keep the phone aligned during the whole connection in order to complete the connection.  If you are traveling in a train or car, this can be difficult depending on what you are doing with your device. No Free to be used for additional Storage Limited to 115.2 kilobits
Serial Cable No Yes - Allows you to pick up the device and use it as needed. Free to be used for additional Storage Limited to 115.2 kilobits
CompactFlash Card No Yes - Allows you to pick up the device and use it as needed. The CompactFlash slot is used to connect to the cellular phone. There is no option to remove the CF card and switch to a CF card to store information. Capable of speeds up to 1 megabit
Bluetooth Yes, limited to 30 feet from phone to Pocket PC No Free to be used for additional Storage Limited to 768k

Right now most customers in the US are using either GSM, CDMA or Nextel digital cellular phones to connect to the internet. These phones are capable of 9600, 14,400 and 9600 bits per second so any of the options listed above are sufficient to accomplish this without hindering performance.  In Europe and the US, GPRS is being rolled out and the speed of the serial cable and infrared will be a limiting factor since GPRS is capable of speeds up to 230k.  Also, in the US the introduction of 1xRTT with speeds of 144k are being rolled out. In these cases a CompactFlash card is recommended.

Connecting to the Office

Cellular allows users to dial up directly to their office systems via RAS just like a PC.  This advantage ensures the same security that a RAS connection has such as using CHAP authentication.  In order to do this you must have the settings to connect via RAS to your company.  GPRS and 1xRTT only offers direct Internet access.  They do not offer RAS access.

Connecting to the Internet

When connecting to the internet, you have 2 options.  You can call your ISP or us the ISP provided by the cellular carrier.  Not all cellular carriers offer their own ISP connection.  The advantage to using your ISP is that you can send and receive e-mail using your default settings in Inbox just like a dialup connection.  The disadvantage is that it takes approximately 45 seconds to connect to your ISP and your ISP must support a 14,400 baud connection.  If they do not then you won't get authenticated.  If your cellular carrier offers their own ISP, then you connect immediately to the internet however you may have problems sending e-mail.  This is done to prevent spammers from using your ISPs mail server.
