Molecular biology science

Molecular biology deals with the biology and chemistry and in particular, genetics and biochemistry. A key area of molecular biology concerns understanding how various cellular systems interact in terms of the way DNA, RNA and protein synthesis function.

Cellular systems

Wireless communications are especially useful for mobile applications, so wireless systems are often designed to cover large areas by splitting them into many smaller cells. This cellular approach introduces many difficulties such as how to avoid interference, or how to hand-over from one cell to another, while maintaining good service quality. Coverage, capacity, interference, and spectrum reuse are important concerns of cellular systems; this chapter reviews these aspects as well as the technologies, tools, and standards used to optimize them.
