Apple разрешает использование стандарта 802.11n

Компания Apple, по информации CNET News, во вторник выпустила специализированное программное обеспечение, необходимое для активации беспроводной связи стандарта IEEE 802.11n в "Маках" на основе процессоров Intel Core 2 Duo.

Стандарт 802.11n теоретически обеспечивает возможность передачи данных в беспроводных сетях со скоростью до 600 Мбит/с. Для сравнения, пропускная способность каналов связи на основе стандарта WiMAX составляет до 70 Мбит/с. Стандарт 802.11n обратно совместим с 802.11a/b/g и использует нелицензируемые в большинстве стран частотные диапазоны 2,4 ГГц и 5 ГГц. Тем не менее, в настоящее время разработка спецификации 802.11n еще не завершена. Более того, ратификация стандарта может затянуться до 2008 года, хотя многие эксперты полагают, что окончательный вариант спецификации будет мало чем отличаться от чернового.

Поддержка 802.11n реализована практически во всех компьютерах Apple на основе Core 2 Duo (за исключением начальной версии iMac с процессором, работающим на частоте 1,83 ГГц). Однако из-за отсутствия окончательной версии спецификации стандарта 802.11n Apple изначально деактивировала чип беспроводной связи. Впрочем, теперь, как сообщает CNET News, пользователи могут активировать беспроводную связь при помощи специальной утилиты, которая стоит 1,99 доллара США.

Кроме того, организовать беспроводную сеть стандарта 802.11n можно при помощи новой базовой станции 802.11n Airport Extreme Base Station стоимостью в 179 долларов. И базовую станцию, и утилиту активации уже можно приобрести через онлайновый магазин Apple Store.

Кстати, не так давно новый контроллер беспроводной связи стандарта 802.11n представила корпорация Intel. Чип Next-Gen Wireless-N станет частью мобильной платформы Centrino Duo, а первые ноутбуки с этим контроллером уже начали поставлять Acer, Asus, Gateway и Toshiba.
