4400MHz—4500MHz频段IMT与航空无线电导航业务共存研究
|
摘要
WRC-15为国际移动通信系统新增了三段频率,对于其中的4400MHz—4500MHz频段,工作在该频段的IMT系统与4200MHz—4400MHz频段的航空无线电导航业务会存在共存的问题。针对两种业务的邻频共存干扰情况进行研究,研究结果表明:在飞机平稳飞行状态下二者可以共存,但是在起飞降落状态下需要保证基站距离飞机着陆点至少2.1 km。
The WRC-15 has newly supplemented three frequency bands for the IMT. For the band 4 400 MHz—4 500 MHz, the problem of coexistence between the IMT system at the band and the aerial radio navigation service at the 4 200 MHz—4 400 MHz would happen. The coexistence interference of these two services is studied. The results show that these two services can coexist in the steady fl ight for aircrafts, and the base station should be at least 2.1 km away the landing point in the landing or taking state for aircrafts.
