A)use small cells.

E)use as few frequencies as possible.

Question

Multiple access is a key design element of any cellular system to overcome the limitation of limited frequencies available. Multiple access techniques like time division multiple access (TDMA), frequency division multiple access (FDMA), and code division multiple access (CDMA) allow multiple users to share the same frequency band simultaneously by dividing the available frequency spectrum into multiple channels. This enables efficient utilization of limited frequencies without compromising the quality of service. Hence, option B is the best choice. Option A is not the only solution as it may not always be feasible or cost-effective to deploy small cells. Option C is not a practical solution as cellular systems are designed to accommodate several users simultaneously. Option D is not always possible due to spectrum scarcity, and option E is not an optimal solution for efficient utilization of limited frequencies.
