A star Bluetooth network is composed of 7slaves and a master . A synchronous communication mode is considered where the effective bit rate is 430Kbps . Assume that the token size is 100 bits and the data size is 1480 bits 1- Determine the time efficiency of the network if only four slaves are sending data 2- What will be the time efficiency of the network if the data size is 720 bits only ? 3- Compare the two efficiencies and conclude about the effect of data size 4- The master is having two slaves only . The first one is having a voice channel , the second is having an asynchronous data traffic a ) The voice traffic is 64kbps , each Bluetooth time slot supports 240bits , what is the time gap between two voice slots ? b ) What is the maximum bitrate allowed to the second slave ? Sketch the time diagram of the flow between the master and its two slaves
