Although wireless networking began to penetrate the market in the s, the technology has actually been around since the s. This provides a focus for the work of equipment developers and service providers and is as much a contributor to the growth of wireless networking as the power of the underlying technologies. Wireless networks WPAN - wireless personal area network Bluetooth ft protocol; Kbps wireless mouse, keyboard, or These optical 5. As shown in Figure 1 a , the worldwide number IP addresses are 32 bit long, hierarchical addressing scheme.
In GSM, these channels are separated into physical channels and logical channels. The Physical channels are determined by the timeslot, whereas the logical channels are determined by the information carried within the physical channel. It can be further summarised by saying that several recurring timeslots on a carrier constitute a physical channel. These are then used by different logical channels to transfer information. These channels may either be used for user data payload or signalling to enable the system to operate correctly. The channels may also be divided into common and dedicated channels. The forward common channels are used for paging to inform a mobile of an incoming call, responding to channel requests, and broadcasting bulletin board information.
It identifies functions to be performed by a signaling-system network and a protocol to enable their performance. 3. Common Channel Signaling .

Control Signal Signalling system must be compatible with Transmission and the switching systems of the network.

Signaling techniques enable the circuit to function as a whole by inter connecting all varieties of switching systems. There are three forms of signaling involved in a telecommunication network. The subscriber loop signaling depends upon the type of telephone instrument used.
Thus, with PCM, a convenient way of transmission is possible. The signalling information and speech information carried in the same time slot is referred as inslot signalling. The signalling information carried in a separate time slot is referred as outslot signalling. Telephone channels are combined by time division multiplexing to form an assmebly of 24 or 30 channels. This is known as primary multiplex group. Two frame structures are widely used in practice. They are DS1 24 channel system and European 30 channel system.
