Question 1 |
Consider the following statements S1 and S2 :
S1 : A hard handover is one in which the channel in the source cell is retained and used for a while in parallel with the channel in the target cell.
S2 : A soft handover is one in which the channel in the source cell is released and only then the channel in the target cell is engaged.
S1 : A hard handover is one in which the channel in the source cell is retained and used for a while in parallel with the channel in the target cell.
S2 : A soft handover is one in which the channel in the source cell is released and only then the channel in the target cell is engaged.

Both S1 and S2 are true. | |
Both S1 and S2 are not true. |
Question 1 Explanation:
→ Hard handover (or) Hard Handoff: Early systems used hard handoff. In a hard handoff, a mobile station only communicates with one base station. When the MS moves from one cell to
another, communication must first be broken with the previous base station before communication can be established with the new one.
→ Soft handover (or) Soft Handoff: New systems use a soft Handoff. In this case, a mobile station can communicate with base stations at the same time. This means that, during handoff, a mobile station may continue with the new base station before breaking off from the old one.
→ Soft handover (or) Soft Handoff: New systems use a soft Handoff. In this case, a mobile station can communicate with base stations at the same time. This means that, during handoff, a mobile station may continue with the new base station before breaking off from the old one.
