大都市は、警察署のラップトップが市政府の VPN に接続する機能の標準化を検討しています。市は、最小限の送信塔で市内全域に最大のカバレッジを提供するワイヤレス ソリューションを望んでいます。遅延と全体的な帯域幅のニーズはそれほど高くありません。優先順位が高い。次のうち、市のニーズを最もよく満たすものはどれですか?
正解:B
The question asks for a wireless solution that provides the largest coverage across the city with a minimal number of transmission towers. Latency and overall bandwidth needs are not high priorities.
5G is a wireless technology that offers high speed, low latency, and large capacity, but it requires more transmission towers and has a shorter range than 4G1.
LTE stands for Long Term Evolution and is a 4G wireless technology that offers wide coverage, good speed, and moderate latency. It uses fewer transmission towers than 5G and has a longer range2.
Wi-Fi 4, Wi-Fi 5, and Wi-Fi 6 are wireless standards that operate in the 2.4 GHz and 5 GHz frequency bands. They offer high speed, low latency, and large capacity, but they have a limited range and require more access points than cellular technologies3.
Therefore, the best option for the city's needs is LTE, as it provides the largest coverage with a minimal number of transmission towers, and does not require high speed or low latency.
