Real-World Range Testing

　　本文概述了RF頻率范圍測試的成功過程，該測試提供了RF鏈路在預(yù)期環(huán)境中如何執(zhí)行的定量數(shù)據(jù)。這使得對網(wǎng)絡(luò)架構(gòu)的知情決定。

　　文章還解釋了在RF范圍測試中可能會影響性能的細微差別。雖然這些原則適用于任何無線電，我們給予特別關(guān)注的802.15.4標準，會影響測試結(jié)果的功能范圍。

　　RF量程測試的設(shè)計被分解，并使用ls研究射頻模塊在實際范圍測試中解釋特定的元素。

　　So many variables

　　One of the most frequently asked questions about a given radio is “How far will this radio transmit？” Unfortunately， it is also one of the most difficult questions to answer， as so many variables apply. Besides obvious variables like transmit power and receive sensitivity， a host of other factors come into play. Without careful attention to understanding and controlling as many of these variables as possible， the results of an RF range test will leave more questions than answers.
