The correct answer is: C. MAHO
Cellular handover (also known as handoff, hand-over, or hand-off) is the process of transferring an ongoing call or data connection from one cell to another. This is necessary when a mobile device moves out of range of one cell and into the range of another.
There are several different types of handover, but the most common type in first generation analog cellular systems is mobile-assisted handover (MAHO). MAHO is a type of handover in which the mobile device itself helps to coordinate the handover with the base stations. This is done by the mobile device measuring the signal strength from the two base stations and then reporting this information to the base stations. The base stations then use this information to determine when and how to make the handover.
The other options are not associated with the handoff in first generation analog cellular systems.
- Breathing cell is a technique used to improve the performance of cellular systems by reducing the size of cells in areas with high traffic density. This is done by increasing the power of the base stations in these areas, which causes the cells to shrink.
- Locator receiver is a device used to track the location of a mobile device. This is done by the locator receiver receiving signals from the mobile device and then using these signals to determine the location of the mobile device.
- Cell dragging is a technique used to improve the performance of cellular systems by moving base stations around. This is done by the base stations being moved to areas with high traffic density.
