However, a local area network (LAN) within these structures is necessary to continue high-speed data transmission to and from end-use devices, such as cameras, displays, printers, high resolution video, mobile communicators, and novel devices.
We envision a network server being the gateway between the NGI and the local area network.
The WiGLAN network adapter consists of three functions, digital signal processing for multi-carrier adaptive bit rate QAM, a baseband analog processor performing data conversion and filtering, and an RF transceiver function which interfaces the modulated baseband data to a 5.8 GHz carrier.

A VLAN is a logical local area network comprised of a plurality of physical local area networks as determined by some network administrator-defined criteria, e.g., grouping local area networks based on geographical topology of the data network, or business units/functions of a company, such as finance or engineering departments.
A network device (e.g., a network switch) has been configured so that a virtual local area network identifier representing a virtual local area network is assigned to each port on the network device.
For example, the type of network switch which has a single VLAN identifier associated with each port and assumes that a data frame received on a port is destined for the VLAN associated with that port is just one type of network switch.
