Air interface tailored to minimize current consumption
Basic Technical Information—Based upon a small, high performance integrated radio transceiver, each of which is allocated a unique 48-bit address derived from the IEEE 802.standard.
Operate in the unrestricted 2.45GHz ISM free band, Which is available globally although slight variation of location and width of band apply.
Range set at 10m to optimize for target market of mobile and business user
Gross data rate 1Mbit/s with second generation plans to increase to 1Mbit/s
One-to-one connections allow maximum data transfer rate of 721kbit/s （3 voice channels）
Uses packet switching protocol based on frequency hop scheme with 1600 hops/s to enable high performance in noisy radio environments. The entire available frequency spectrum is used with 79 hops of 1Mhz bandwidth, analogous to the IEEE 802.11 standard.
Low power consumption longevity for battery powered devices. During data transfer the maximum current drain is 30mA. However during pauses or at lower data rates will be lower.
藍(lán)牙是一個(gè)頻率為2.45GHz的通用無(wú)線電通信接口，它通過(guò)一個(gè)特殊的網(wǎng)絡(luò)可以在各種便攜設(shè)備之間建立起無(wú)線連接并進(jìn)行短程通信。在一個(gè)微微網(wǎng)中，每個(gè)單元都能同時(shí)與其它各單元進(jìn)行通信。而且，每一個(gè)單元可以同時(shí)屬于幾個(gè)微微網(wǎng)。
