Необходим перевод текста. bluetooth security is taken care of through the frequency hopping and 40-bit encryption. as the system uses radio, it сan work through some barriers – briefcases, shirt pockets and desktops, for example – but it won’t carry through office buildings. the power level of the transmitter can be varied, with feedback from the remote side of the link used to set the output to the lowest level commensurate with error-free operation. this saves power and increases the usable density of devices.

Как и положено экспертам в области радиочастот, Ericsson и Nokia разработали радиочастотную сторону Bluetooth. Соединение работает в подобном путе к системе беспроводной сети IFEE 802.11, при протокол пакетной коммутации основанный на Спектре распространения сразу последовательности быстр-частоты прыжков. Другими словами, он постоянно переключает канал, чтобы избежать помех. Он изменяет частоту 1600 раз в секунду через 79 частотных полос. Ожидается, что это будет настолько хорошо, чтобы избежать конфликтующих сигналов от других источников, что мощность передачи может быть очень низкой.
