// Exa 19.1
// To calculate the hopping rate of bluetooth, No of bits transmitted in one slot, efficiency of packet transmission, and No of times a packet is sent.

//From table 19.3:Bluetooth air interface details, we get Frequency hopping rate as 1600hopes/second
//From table 19.5, we can note that for HV3, No of slots are 1 and carry in all(80(user voice sample)+160(parity bits))=240 bits in one slot packet
