The last infrared equipped Mac was the first iMac. After that Apple scrapped the thought of infrared as a practical networking solution. This is because the remote control's beam is rather weak and unable to provide the signal strength needed for data. Therefore, it is very impractical for schools and normal home networks. Airport Another type of wireless networking has arrived called Airport.
Airport uses radio signals.
All that is required is a couple of Airport cards and the optional Base Station. It is an entirely seamless operation. Unfortunately, Airport has a few problems. First, Airport can t support Apple s claims of 11 MBps. Airport can t even come close when using the Base Station.
