| Беспроводная точка доступа The Cisco® 521 работает по стандарту 802.11g и поддерживает управление, безопасность и масштабируемость. Эта точка доступа предоставлюет высокую скоросто беспроводного доступа в офисах и аналогичных средах.
Cisco Mobility Express Solution объединяет точки доступа Cisco 521 и контроллер Cisco 500 Series Wireless Express Mobility Controller для предоставления надёжного и эффективного по цене беспроводного решения расчитанного для нужд малого и среднего бизнеса (SMBs). Mobility Express Solution является частью Cisco Smart Business Communications System (SBCS) - унифицированные коммуникации для SMBs которые предоставкляют голос, данные, видео, безопасность и беспроводные возможности как единое решение.
• Самостоятельный режим: точка доступа подключается напрямую к проводной инфраструктуре (коммутатор) и предоставляет высокоскоростное беспроводное подключение пользователям в зоне покрытия. Конфигурирование и управление производится на каждой точке индивидуально.
• Режим совместно с контроллером: Точка доступа подключается напрямую к проводной инфраструктуре через свич и ассоциируется с Cisco 500 Series Wireless Express Mobility Controller. Контроллер устанавливает конфигурацию всех подключенных к нему точек доступа через единый интерфейс, и предоставляет платформу для организации безопасного гостевого беспроводного доступа и голоса поверх Wi-Fi.
