• Wireless Networking NTK - Product Types*
  Thursday 5 December 2002 – 09:00
  Wireless products come in many different "flavors" and differences between some of them are subtle. Let's start by looking at the different types of "Client Adapters". These products are used to connect one device to a wireless network, much like an Ethernet network interface card (NIC). Most of the adapters can work either in a peer-to-peer network (this is called Ad Hoc mode), or through an Access Point that connects to a larger, usually wired, network (Infrastructure mode). HomeRF based devices also support both methods of communication, but switch methods on the fly. PC CardThis format is familiar to laptop and PDA users and comes in 16bit and CardBus (32 bit) forms. Unfortunately, manufacturers often don't tell you which technology they use, so if your laptop supports only CardBus adapters, you may have do experiment to find out whether a product will work for you. PC Cards have been the format of choice for laptop users, but have the disadvantages of relatively high power usage and poor antenna orientation.
