IT in the mobile communications industry
| "I'm on the bus". If you've wondered why your trusty mobile was also called a cell phone, here's the reason. Mobile phones are not really phones at all, but short range radios. There are only so many 'channels' or 'frequencies' you can use for sending signals by radio. |

Someone in Cork could be using the same frequency as someone in Sligo, but because mobile phones have only a short range it doesn't matter. |
