Question
State the concept of mobile telephony and explain its working.
✓
Answer
Concept of mobile telephony is to divide the service area into a suitable number of cells centred on an office MTSO (Mobile Telephone Switching Office)/Mobile telephony means that you can talk to any person from anywhere.
Explanation:
Explanation:
- Entire service area is divided into smaller parts called cells.
- Each cell has a base station to receive and send signals to mobiles.
- Each base station is linked to MTSO. MTSO co-ordinates between base station and TCO (Telephone Control Office).

The space between the plates of a parallel plate capacitor is completely filled in two ways. In the first case, it is filled with a slab of dielectric constant K . In the second case, it is filled with two slabs of equal thickness and dielectric constants $\mathrm{K}_1$ and $\mathrm{K}_2$ respectively as shown in the figure. The capacitance of the capacitor is same in the two cases. Obtain the relationship between $\mathrm{K}, \mathrm{K}_1$ and $\mathrm{K}_2$.
