Spectrum Diffusion Transmission
A method of transmission in which signals that are normally transmitted over a given limited frequency band undergo narrow band modulation (primary modulation), then again diffuse modulation (secondary modulation) to intentionally diffuse the signal over a broad frequency spectrum.
Channel
This term has the same meaning as a television or radio channel. In the 2.400 to 2.472GHz ISM band used by this product, the IEEE 802.11 standard provides for divi- sion into 11 channels numbered 1 to 11.

It can be used to connect networks having different protocols, or when data for broadcast to all comput- ers is received, can send this to all connected networks.
Router
A device for relaying between LAN's. The router determines data addresses by the combination of a network address assigned to the network and an individual computer address. Used particularly in
Roaming
