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 ]

Mobile E-Commerce (MEC)
Mobile E-Commerce (MEC) is defined as any type of transaction of an economic value conducted through a mobile terminal that uses telecommunications network for communication with the e-commerce infrastructure.
Toward’s the end of the last century, the integration of the wireless communication and e-commerce started to emerge. As e-commerce technologies advance into the 21st century and more technical hurdles are eliminated in mobile computing, there is no doubt that the popularity of mobile e-commerce will further increase.

A mobile station communicates with another station, either mobile or land, via a base station. A mobile station cannot communicate with another mobile station directly. To make a call from a mobile station, the mobile station first needs to make a request using a reverse control channel of the current cell. If the request is granted by the MSC, a pair of voice channels will be assigned for the call. To route a call to a mobile station is more complicated.

The network first needs to know the MSC and the cell in which the mobile station is currently located. How to ..................==> [ Click Here to Read More ]

CDPD technology which uses the existing mobile network. Mobility implemented in data communications has a significant difference compared to voice communications. Mobile phones allow the user to move around and talk at the same time; the loss of the connection for 400ms during the hand over is undetectable by the user. When it comes to data, 400ms is not only detectable but causes huge distortion to the message. Therefore data can be transmitted from a mobile station under the assumption that it remains stable or within the same cell.
