目前,四种主要宽带技术较为流行,它们分别是DSI.、光缆、卫星和陆基无线技术。 这四种技术各有优劣。在DSI。技术中,不对称DsL(ADSI。)目前在英国和世界很多地方都有采用,这种宽带技术在现有的电话线路上使用新的数据压缩方式,这是该技术的主要优势所在。
Currently, four major broadband technologies are popular: DSI, fiber optic cable, satellite and land-based wireless technologies. The four technologies have their own advantages and disadvantages. At DSI. In technology, asymmetric DsL (ADSI.) Is currently used in many parts of the UK and the world, and this broadband technology uses new data compression methods over existing telephone lines, which is a key benefit of this technology.
