Detailed explanation-1: -Which of the following is associated with the handoff in first generation analog cellular systems? Explanation: Locator receiver is a spare receiver in each base station. It is used to scan and determine signal strengths of mobile users which are in neighbouring cells.

Detailed explanation-2: -Explanation: In first generation analog cellular system, the typical time to make a handoff once the signal level is below the threshold, is about 10 seconds.

Detailed explanation-3: -Handoff can be categorized as hard handoff, soft handoff, and softer handoff. The hard handoff can be further divided into intrafrequency and interfrequency hard handoffs. During the handoff process, if the old connection is terminated before making the new connection, it is called a hard handoff.

Detailed explanation-4: -Which of the following is true for first-generation wireless systems? Explanation: First generation wireless systems provide analog speech and inefficient, low rate, data transmission between the base station and mobile user.

Detailed explanation-5: -In cellular communications, the handoff is the process of transferring an active call or data session from one cell in a cellular network or from one channel to another. In satellite communications, it is the process of transferring control from one earth station to another.
