FREQ. REUSE IN CELLULAR N/W'S • Power of base transceiver controlled - Allow communications within cell on given frequency - Limit escaping power to adjacent cells - Allow re-use of frequencies in nearby cells - Use same frequency for multiple conversations - 10 - 50 frequencies per cell • E.g. - N cells all using same number of frequencies - K total number of frequencies used in systems - Each cell has K/N frequencies - Advanced Mobile Phone Service (AMPS) K=395, N=7 giving 57 frequencies per cell on average

How fractional frequency reuse can be used to decrease the number of cells used in a cellular network?
divide cells into rings which will operate with different levels of frequency reuse
How are sound frequency and wavelength related?
As freuency increses so does it's wavelength
Difference between adhoc network and cellular network?
to reduce power consumption and reuse the limited radio spectrum resources, a cellular network was formed. cell size is one of the factors in channel reuse rate.basically channel reuse rate in smaller cell size is higher than the channel reuse rate in bigger cell size.A cellular architecture would then present a challenge to the frequent handover procedure to the smaller cell size would usually induce a higher hand-off frequency. in addition to cellular network an adhoc network is another network architecture for wireless networks. The adhoc network is non infrastructure network in which nodes can access services from one another regardless where they are. the main difference between a cellular environment and adhoc network is that the adhoc method has no infrastructure allowing nodes to communicate with one another at any time and any where.

What is the function of the lysosome in a cell and how does it contribute to cellular processes?
The lysosome is an organelle in a cell that acts as a recycling center, breaking down waste materials and old cell components. It helps maintain cellular health by removing debris and recycling nutrients for reuse in cellular processes.
