opping Spread Spectrum FHSS
In Frequency Hopping the transmission band is divided into dierent frequency channels typically 
and a logical channel ie a channel on which two or more devices communicate hops periodically from
one frequency channel to another with a pseudorandom hopping sequence

 Direct Sequence Spread Spectrum DSSS

Also in Direct Sequence the frequency band is divided into fewer but larger
channels but no hopping
is used To compensate for noise on a channel a technique called chipping is implemented each bit is
converted into a redund..................==> [ Click Here to Read More ]

devices, such as smart phones with embedded SIM card to enhance processing power and storage capabilities, carry out many mobile e-commerce transactions. The main driving force for the rapid acceptance rate of mobile e-commerce is its increased convenience and efficiency in performing simple transactions compared with the stationary machines. For example, some transactions involve only a single request and reply between a customer and a merchant, and possible another round trip message exchange between the customer and the bank. Using a mobile device, people can perform these kinds of transac..................==> [ Click Here to Read More ]

find out the current residing cell of mobile station is an issue of location management. Once the MSC the cell of the mobile station, it can assign a pair of voice channels in that cell for the call. If a call is in progress when the mobile station moves into a neighbouring cell, the mobile station needs to get a new pair of voice channels in the neighbouring cell from the MSC so that the call can continue. This process is called as ‘ handoff ‘or ‘ handover ‘. The MSC usually adopts a channel assignment strategy that prioritizes handoff calls over new calls.Providing connection-oriente..................==> [ Click Here to Read More ]

arts of the network and allow access to the fixed Public Switched Telephone Network (PSTN). The technology is hidden from view; it's incorporated in a number of tranceivers called Base Stations (BS). Every BS is located at a strategically selected place and covers a given area or cell - hence the name cellular communications. A number of adjacent cells grouped together form an area and the corresponding BSs communicate through a so called Mobile Switching Centre (MSC). The MSC is the heart of a cellular radio system. It is responsible for routing, or switching, calls from the originator to the..................==> [ Click Here to Read More ]
