WebThe Bluetooth protocol RFCOMM is a simple set of transport protocols, made on top of the L2CAP protocol, providing emulated RS-232 serial ports (up to sixty simultaneous connections to a Bluetooth device at a time). The protocol is based on the ETSI standard TS 07.10. RFCOMM is sometimes called serial port emulation. WebThe frame efficency is ( 1 - boverhead / bT ) * 100 %. The efficiency of a full form of a TDMA system is a measure of the percentage of the data that is transmitted. In this system, the transmitted data has information for providing overhead for the access scheme. We can measure the frame efficiency of TDMA is a percentage of bits per frame ...

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 … See more • Shares single carrier frequency with multiple users • Non-continuous transmission makes handoff simpler • Slots can be assigned on demand in dynamic TDMA See more 2G systems Most 2G cellular systems, with the notable exception of IS-95, are based on TDMA.
