Did You Know?

Cellular cloning is a federal crime in the United States of America. Specifically, it is a crime for any person other than a cellphone manufacturer to alter the electronic serial number in a cellphone, regardless of the purpose. In other words, in the USA there is no such thing as "legitimately" cloning a cellphone.

About Cellular Telephones

Phone-o-rama

Welcome! This section of larwe.com contains a summary of useful information about cellular mobile telephone systems, handsets and services. It is the groundwork for a series of products which I intend to develop for the cellular market; as these products become available, they will be indexed here. Information here, particularly on the definitions page, is also of general interest to people who are curious about cellular technology.

You will find that these pages talk a lot about the GSM digital cellular system. This is partly because the country where I was born and have lived most of my life (Australia) is primarily a GSM country - but a better reason is simply that GSM is the closest thing the world has to a global standardized cellular telephone network. Ground-to-space satellite networks exist (rest in peace, Iridium), but they are expensive and not at all popular at this time. GSM is widely adopted, cheap, and very versatile.

Please select one of the cellular pages available from the menu buttons on the left. Some of the more interesting items available are:
