S1 interface – A Single Interface between LTE RAN and evolved packet core The S1 interface is the interface between the LTE RAN and evolved packet core. S1 interface protocol…

LTE has been designed as a completely packet-oriented multi service system, without the reliance on circuit-switched connection-oriented protocols prevalent in its predecessors. In LTE, this philosophy is applied across all…

The third assumption—that the background noise is Gaussian and uncorrelated with the transmissions—is especially suspect in a cellular MIMO system. All well-designed cellular systems are by nature interference limited: If they…

Here I write about Iu PS Interface in WCDMA. WCDMA Protocol Structure for Iu PS The Iu PS protocol structure is represented in below image. Again, a common ATM transport…

Similar to any radio network, standard isolation would be required if equipment from different vendors are to be combined. Which including guard band, filtering as well as vertical/horizontal separation. In…

Margin sites intrusive noise levels due to an increase can be considered as If sites were spaced closer together than position using the same frequency The thermal noise floor. In…

An RF propagation model is a mathematical formula used to characterize the radio is Wave transmitter at one end and the other end into the receiver propagation between It is…
