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.
藍牙是一個頻率為2.45GHz的通用無線電通信接口，它通過一個特殊的網(wǎng)絡(luò)可以在各種便攜設(shè)備之間建立起無線連接并進行短程通信。在一個微微網(wǎng)中，每個單元都能同時與其它各單元進行通信。而且，每一個單元可以同時屬于幾個微微網(wǎng)。
什么是“藍牙”技術(shù)？
“藍牙”技術(shù)最先是由愛立信開始研制的，現(xiàn)在已經(jīng)得到了諾基亞、IBM、東芝、因特爾及許多其它相關(guān)制造廠家的支持。其目的是為了免除在無繩電話或移動電話、調(diào)制解調(diào)器、頭套式送/受話器、PDAs、計算機、打印機、幻燈機、局域網(wǎng)等之間加裝電線、電纜和連接器。而且，這種技術(shù)可以延伸到那些完全不同的新設(shè)備和新應(yīng)用中去?！八{牙”的技術(shù)特性—以每秒1M個碼元的字符速率傳輸，充分利用信道的有效帶寬。
