摘要: 將5G移動(dòng)通信技術(shù)應(yīng)用于海面覆蓋,不僅僅要解決建站困難的問(wèn)題,還要解決海面超遠(yuǎn)覆蓋下的參數(shù)配置及覆蓋距離估算。首先對(duì)海面超遠(yuǎn)覆蓋進(jìn)行信道建模,考慮空氣介電常數(shù)變化對(duì)無(wú)線電波傳播的影響,給出了等效的地球模型;其次,對(duì)5G中影響小區(qū)覆蓋半徑的幾個(gè)關(guān)鍵參數(shù)進(jìn)行了詳細(xì)分析;最后,分別對(duì)三大運(yùn)營(yíng)商的主流頻段進(jìn)行仿真,給出了不同頻段下最大覆蓋距離與路徑損耗的關(guān)系曲線。

Abstract: When 5G mobile communication technology is applied to sea coverage, it is not only to solve the problem of difficult station construction, but also to solve the parameter configuration and coverage distance estimation under ultra-far sea coverage. In this paper, firstly, the channel model of sea surface ultra-far coverage is built, and the equivalent earth model is given considering the influence of air permittivity change on radio wave propagation. Secondly, several key parameters affecting cell coverage radius in 5G are analyzed in detail. Finally, the main frequency bands of the three operators are simulated, and the relationship curves between the maximum coverage distance and the path loss in different frequency bands are given.
Key words : 5G; sea coverage; cell coverage radius; path loss

隨著海洋資源開(kāi)發(fā)進(jìn)程的加快及5G技術(shù)的飛速發(fā)展,沿海區(qū)域、海面航線及海上島嶼等場(chǎng)景的無(wú)線通信需求越來(lái)越強(qiáng)烈。海面覆蓋與陸地上的無(wú)線覆蓋相比,具有用戶(hù)密度低、容量需求小、無(wú)線電波傳播條件簡(jiǎn)單、多為視距傳播等特點(diǎn),屬于超遠(yuǎn)覆蓋場(chǎng)景中的典型應(yīng)用[1]。在海面上建站,存在難度大、成本高、不易維護(hù)等問(wèn)題[2],運(yùn)營(yíng)商通常會(huì)選擇使用陸地上的基站對(duì)海面進(jìn)行超遠(yuǎn)覆蓋。因此,研究海面無(wú)線信號(hào)的超遠(yuǎn)覆蓋具有十分重要的意義[3]。
本文首先對(duì)海面超遠(yuǎn)覆蓋進(jìn)行信道建模,并給出了可用于計(jì)算覆蓋距離的等效地球模型;其次,對(duì)5G中影響小區(qū)覆蓋半徑的幾個(gè)關(guān)鍵參數(shù)進(jìn)行了詳細(xì)分析;最后,分別對(duì)三大運(yùn)營(yíng)商的主流頻段進(jìn)行仿真,給出了不同頻段下最大覆蓋距離與路徑損耗的關(guān)系曲線。
