Figure B.1 Infrastructure Mode Examples
Some devices may be named for their basic function, but may also
provide Access Point services. For example, a Residential Gateway
may provide Access Point wireless functions while connecting
devices to an enterprise intranet, or the Internet, through a
telephone or broadband connection. However, to be used as an
Access Point on an Infrastructure Mode network, a device must be
able to receive and forward network traffic to all other wireless
devices on the network. For Access Point features, see your vendor's
documentation.
An Access Point has a fixed throughput capacity; therefore, wireless
network performance will depend on the number of wireless devices
connected and types of data transfers. For example, you may only
want to have 10 or 20 power users who transfer large data files, or
up to 50 users that have only occasional network communication
needs. In addition, the distance between a wireless device and the
Access Point will affect performance; longer distances degrade data
transmission rates.
