The UMG8900 supports satellite transmission over the Mc and Nb interfaces. This featurem enhances the networking flexibility of the UMG8900, and enables the UMG8900 to fit long-distance and physically different networks.

In obscure mountainous areas or underpopulated plains, it is costly to lay optical fibers or other transmission devices. Unrestricted by terrain or distance, satellite transmission, which features wide coverage, long transmission distance, and low line cost, can improve the flexibility of office networking in these remote areas.

 In obscure mountainous areas or underpopulated plains, it is costly to lay optical fibers or microwave transmission devices. Unrestricted by terrain or distance, satellite transmission features wide coverage, long transmission distance, and low line cost. Therefore, satellite transmission is the perfect choice for transmission in such areas. Satellite transmission refers to taking the earth satellite as the repeater to transfer microwave signals for communication between two or multiple earth stations. In fact, satellite transmission can be considered as a special form of microwave transmission. Satellite transmission mainly differs from terrestrial transmission in delay. The radio wave is transmitted at the speed of light, and the satellite is about 80000 km away from the earth. Therefore, the unidirectional delay of satellite transmission is 270 ms, and the bidirectional delay (called a hop) is 540 ms. The delay mainly refers to the time for spatial microwave transmission.

This feature is applicable to the VMSC, GMSC, and TMSC.

This featurem enhances the networking flexibility of the UMG8900, and enables the UMG8900 to fit long-distance and physically different networks.

 

.....Its a huge revolution for UMG to connect by far difference introduced by Huawei.

Therefore, the unidirectional delay of satellite transmission is 270 ms, and the bidirectional delay (called a hop) is 540 ms.

 

How can we indentify unidirectional & bidirectional delay?

great presentation

Keep it up guys
