Embodiment Construction

[0051] figure 1 and 2 A portion 1 of a typical WLAN is shown. The WLAN includes a plurality of access point devices 20, each of which has a coverage area 21 over which it can send / receive transmissions to / from one or more client devices 25 (such as a laptop computer). There is overlap between adjacent coverage areas 21 and the area network is configured such that a client device 25 can roam and move to adjacent coverage areas 21 without being disconnected from the area network.

[0052] The access point devices 20 are all connected to a common transmission line 30 . Access controllers 40 designed to control access to the network are connected to the transmission line 30 at a plurality of locations along the length of the transmission line 30 . Said access controller 40 acts primarily as a gateway to other parts of the area network (not shown) by sending / receiving transmissions to / from client devices 25 along said transmission line 30 . They are also used to configure the ...

Abstract

The present invention provides an access point device arranged to receive data packets from one or more client devices and transmit them along an area network characterised wherein the access point device comprises security means arranged to configure the client data packets such that they are directed only to one or more permitted area network device(s).

Description

technical field [0001] The invention relates to the field of computer networks, in particular to the field of area networks. Background technique [0002] A computer network can be defined as a group of two or more computer systems that are linked to each other. In this definition, a computer system means a fully working computer, including not only the computer but also any software or peripherals required to perform the functions of the computer. For example, every computer system requires an operating system, and printing devices are often required to provide hard copies of computerized information. [0003] Computer networks can be classified in various ways, for example according to topology (the geometric arrangement of devices within the network, e.g. bus, star, ring), medium (the means by which devices are connected, e.g. coaxial / fiber-optic cables or radio waves), protocol (the common set of rules, such as Ethernet) or architecture (peer-to-peer or client / server)....
