AMPS operation

AMPS operation: A simple diagram of how AMPS system handles various calls and other responsibilities as shown in below diagram. As the power up, all mobile station is in the range of a base station which go through a registration with AMPS before actual service starts. According to the stateRead More →


Cell traffic load is typically characterised has the two important distributed parameters. Average number of mobile stations requesting the service (average call arrival rate (λ). Average length of time the mobile stations requiring the service (average holding time T). The offered traffic load is defined as                                         a= λT. ForRead More →

Fundamental concept of cellular system: Let see example of cordless telephone used at home which employed wireless technology, which has less coverage and smaller amount of power. All the users use same frequency range without much inference among users. Same frequency interference avoidance is used in cellular system with muchRead More →

FAST ETHERNET: In order to compete with LAN protocols fast ethernet was can transmit data 10 times faster when compared with standard ethernet. It has 100mbps data rate, which has same minimum and maximum frame length when compared with standard ethernet. A new feature which added to fast ethernetRead More →

DIFFERENT TYPES OF ETHERNET: Depending on the encoding and decoding operation Ethernet are categorized into four: STANDARD ETHERNET: Standard Ethernet is implemented using digital signaling with the data rates of 10 Mbps.  Whereas at the sender, the data is converted into a digital signal using Manchester scheme. While at theRead More →
