$2.$ a$.$ The time gaps of normal, frequency correction, and synchronization bursts, shown in the below figure are designed to allow power ramping. What is the allowable power ramping time for GSM receivers?

b$.$ The time gap of the random access burst is designed to assure this packet does not collide with the normal bursts. What is the maximum coverage, the distance

between the BS and MS of a GSM base station? Assume that this gap is reserved for two$-$way travel and radio wave travel at $\backslash (300,000\backslash$mathrm$\{$Km$\}/\backslash$mathrm$\{$sec$\}\backslash ).$

c$.$ The length of the synchronization sequence in synchronization burst is designed to allow time advance for two$-$way bit synchronization. Use this parameter to calculate the maximum coverage of GSM$.$ Compare your results with that of part $($b$).$
