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 ]

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 ]

ng data, but rather it is different.They both have their place in the cellular wireless solution, and it may take the combination of both services to provide the customer with the optimal solution.As stated above, the two technologies are different. CDPD is connection-less. It sends each packet intermittently, when there is space available. Circuit Switching on the other hand, sends the data over a continuous connection. For this reason, CDPD would be the optimal solution for a customer who is sending information which is both short and bursty, the circuit switch solution would be ..................==> [ Click Here to Read More ]

al: here the differences in the time of arrival of the signal from the mobile to more than one base station are used to calculate the location of the device.
• Angle of arrival: AOA is a system that calculates the angle at which a signal arrives at two base stations from the handset, using triangulation to find location.
