Которые отличаются небольшой дальностью действия, требуют прямой видимости между пультом и устройством. Расширенными возможностями будут обладать новые системы управления на основе перспективного беспроводного стандарта ZigBee. <br /><br />В ZigBee предусмотрена отдельная спецификацией RF4CE, которая определяет требования к дистанционному управлению, такие системы будут удобными, надежными и недорогими, позволят управлять разнообразными устройствами  в составе домашней сети. <br /><br /><b>Некоторые из основных характеристик ZigBee RF4CE:</b><br />•	Работа в диапазоне частот 2,4 ГГц в соответствии с требованиями IEEE 802.15.4<br />•	Использование нескольких частотных каналов<br />•	Сверхнизкое энергопотребление<br />•	Управление устройствами в составе сети<br />•	Различные варианты передачи управляющих сигналов<br />•	Использование механизмов шифрования личной информации.<br /><br /><div align="center"><!--dle_image_begin:http://www.hdtv.ru/uploads/posts/2012-11/1353851012_zigbee.jpg|--><img src="http://www.hdtv.ru/uploads/posts/2012-11/1353851012_zigbee.jpg" alt="Технология ZigBee в ПДУ телевизоров" title="Технология ZigBee в ПДУ телевизоров"  /><!--dle_image_end--></div>
