TDMA in Share medium

-

Time division multiple access (TDMA) is a channel access method for shared medium networks. It allows several users to share the same frequency channel by dividing the signal into different time slots. The users transmit in rapid succession, one after the other, each using its own time slot. This allows multiple stations to share the same transmission medium (e.g. radio frequency channel) while using only a part of its channel capacity. TDMA is used in the digital 2G cellular systems such asGlobal System for Mobile Communications (GSM), IS-136, Personal Digital Cellular (PDC) and iDEN, and in the Digital Enhanced Cordless Telecommunications(DECT) standard for portable phones. It is also used extensively in satellite systems, combat-net radio systems, and PON networks for upstream traffic from premises to the operator. For usage of Dynamic TDMA packet mode communication

Any standard software process model would primarily consist of two types of activities: A set of framework activities, which are always applicable, regardless of the project type, and a set of umbrella activities, which are the non SDLC activities that span across the entire software development life cycle. Typical activities in this category include: 01.   Software project tracking and control :   Tracking and Control is the dual process of detecting when a project is drifting off-plan, and taking corrective action to bring the project back on track. But a successful project manager will also be able to tell when the plan itself is faulty, and even re-plan the project and its goals if necessary. 02.   Formal technical reviews :   This includes reviewing the techniques that has been used in the project. 03.   Software quality assurance :   This is very important to ensure the quality measurement of each part to ensure ...
