5G 微基站與智能路燈
5G MICRO BASE STATION AND INTELLIGENT STREET LAMP
5G 網(wǎng)絡(luò)與物聯(lián)網(wǎng)推廣為智慧路燈發(fā)展契機(jī)。5G 網(wǎng)絡(luò)與 3G、4G 網(wǎng)絡(luò)有較大的不同，除了滿足以往的增強(qiáng)型移動寬帶場景外，還增加了低延時通信和海量機(jī)器通信兩個場景。也就是說，5G 網(wǎng)絡(luò)除了提高人與人的通信速度外，還要滿足通信所需要的低延時和高密度的性能。由于 5G 使用的頻率高于 4G，雖然提高了傳輸速度，但是信號傳輸?shù)木嚯x變短，因此單位面積內(nèi)基站的需求量提高。相對比宏基站，小基站具備體積功耗小，集成度高，部署便捷等優(yōu)點，因此，5G 時代將會催生小基站很大的需求。小基站的安裝方式主要有三種：抱桿安裝、樓面安裝、地面安裝。智慧路燈上安裝小基站為可行的抱桿安裝方式之一，將會催生智慧路燈大量需求。目前物聯(lián)網(wǎng)已經(jīng)廣泛應(yīng)用于智能停車、智慧城市、智能生產(chǎn)、智能家居等領(lǐng)域，物聯(lián)網(wǎng)的發(fā)展，將使智慧路燈“更加智慧”。利用物聯(lián)網(wǎng)無線通信技術(shù)，通過物聯(lián)網(wǎng)，所有的智慧路燈形成一張相互聯(lián)結(jié)的網(wǎng)絡(luò)，通過軟件平臺對各個路燈上傳的大數(shù)據(jù)進(jìn)行整理和分布式處理，實現(xiàn)城市的實時管理。
The promotion of 5g network and Internet of things is an opportunity for the development of smart streetlights. 5g network is quite different from 3G and 4G network. In addition to meeting the previous enhanced broadbａnd scenarios, it also adds two scenarios of low delay communication and mass machine communication. In other words, 5g network not only improves the communication speed between people, but also meets the requirements of low delay and high density performance. Because 5g frequency is higher than 4G, although the transmission speed is improved, the distance of signal transmission is shorter, so the demａnd of base station per unit area is increased. Compared with the macro base station, the small base station has the advantages of small size, low power consumption, high integration and convenient deployment. Therefore, 5g era will give birth to a huge demａnd for small base stations. There are three main installation methods of small base station: derrick installation, floor installation and ground installation. The installation of small base stations on smart street lamps is one of the most feasible installation methods for holding poles, which will lead to a large demａnd for smart street lamps. At present, the Internet of things has been widely used in intelligent parking, smart city, intelligent production, smart home and other fields. The development of the Internet of things will make the smart street lamp "more intelligent". Using the wireless communication technology of the Internet of things, through the Internet of things, all the intelligent street lamps form a huge network connected with each other. Through the software platform, the big data uploaded by each street lamp is sorted out and distributed, so as to realize the omnidirectional real-time management of the city.
