Before using the roaming function the workstation must make sure that it is the same channel number with the access point of dedicated coverage area To achieve true seamless connectivity the wireless LAN must incorporate a number of different functions Each node and access point for example must always acknowledge receipt of each message Each node must mbps one million bits per second a unit of measurement for data transmission fragmentation breaking a packet into smaller units when transmitting over a network medium that cannot support the original size of the packet 31 maintain contact with the wireless network even when not actually transmitting data Achieving these functions simultaneously requires a dynamic RF networking technology that links access points and nodes In such a system the user s end node undertakes a search for the best possible access to the system First it evaluates such factors as signal strength and quality as well as the message load currently being carried by each access point and the distance of each access point to the wired backbone Based on that information the node next selects the right access point and registers its address Communications between end node and host computer can then be transmitted up and down the backbone As the user moves on the end node s RF transmitter regularly checks the system to determine whether it is in touch with the original access point or whether it should2.
