Detailed explanation-1: -Techniques such as cell splitting, sectoring and coverage zone approaches are used in practice to expand the capacity of cellular system.
Detailed explanation-2: -Random access protocols refer to communication protocols used in computer networks. Hence, each device has an equal privilege to access the network and transmit data. These protocols allow nodes to send and receive data without taking turns or waiting for permission.
Detailed explanation-3: -There are five basic access or multiplexing methods: frequency division multiple access (FDMA), time division multiple access (TDMA), code division multiple access (CDMA), orthogonal frequency division multiple access (OFDMA), and spatial division multiple access (SDMA).
Detailed explanation-4: -A random-access channel (RACH) is a shared channel used by wireless terminals to access the mobile network (TDMA/FDMA, and CDMA based network) for call set-up and bursty data transmission. Whenever mobile wants to make an MO (Mobile Originating) call it schedules the RACH.
