室內行動網路收訊品質之改善方法與探討

隨著時代的進步，科技發展與日俱增，社會大眾對於網路服務的使用也已漸漸增加其依賴，從早期的窄頻撥接，到現在的xDSL寬頻上網、光纖上網、行動上網等，有限及無線頻寬的成長似乎是無止境的，尤其行動上網更是發展神速，只因為人們總是有新的應用、新的服務需求，而無線網路技術的進步，讓網路服務的使用更為方便。無線網路技術從紅外線、藍芽和IEEE 802.11無線區域網路，行動通訊也從2G(Global System for Mobile Communications；GSM)提升至3G (Universal Mobile Telecommunications Service；UMTS)、4G (Long Term Evolution；LTE) ，近幾年4G LTE發展快速，讓許多國際大廠等，更視它為未來網路電信產品的明日之星。本文研究的目的在於了解室內3G、4G收訊品質的優劣問題，分析室內訊號收訊強度接收訊號碼功率(Received Signal Code Power；RSCP)、信雜比(Signal-Noise Ratio；SNR)及接收的信号强度指示(Received Signal Strength Indication；RSSI)，解決室內用戶收訊問題，進而研討相關因應解決方法。

with increasing progress, scientific and technological development of the times, the general public for the use of web services has gradually increased its dependence from the early narrowband dial-up, and now the xDSL broadband access, fiber access, mobile Internet access, and wireless limited bandwidth growth seems to be endless, especially the mobile Internet is developing rapidly, just because people are always new applications, new demand for services, and advances in wireless network technology, allowing the use of web services easier . Wi-Fi technology from infrared, Bluetooth and IEEE 802.11 wireless LAN, mobile communications from 2G (Global System for Mobile Communications；GSM) up to 3G (Universal Mobile Telecommunications Service；UMTS), 4G (Long Term Evolution；LTE), 4G LTE rapid development in recent years, so many international companies etc., but also see it as the future stars of tomorrow telecommunications network products. The purpose of this study is to understand the indoor 3G, 4G reception quality of the merits of the issue, analyze indoor signal reception strength Received Signal Code Power (RSCP), Signal-Noise Ratio (SNR) and Received Signal Strength Indication (RSSI), users solve indoor reception problems and then discuss solutions related response.
