Embodiment Construction

[0040] The method of the invention avoids the frequency spectrum resource used by the existing wireless network by utilizing the principle of frequency staggering, achieves the purpose of area coverage through the frequency conversion of the repeater, and reduces the interference to the network. The method of the present invention can be applied to all wireless networks. If the cost of building base stations is considered, the method and network described in the method are especially suitable for residential areas with relatively dense building groups, and simultaneously realize indoor coverage of multi-point areas. In the following, the implementation of indoor coverage by a 3G broadband access network will be described in detail in conjunction with the accompanying drawings.

[0041] The working frequency band of the 3G wireless signal transmitted by the 3G broadband network is about 2.1 GHz. This embodiment takes the 3.5 GHz frequency point outside the 3G frequency band as a...

Abstract

This invention discloses a region covery method of radio signals and a radio access network for realizing it including: a base station emits down-radio signals on a set frequency point outside of the band occupied by said radio network and receives the up-radio signals, a playover station receives the down radio signals of the base station to convert the working frequency point of said radio signals to the inside of the band of the radio network and emits to receive said up radio signals in the band occupied by the network of the terminal and converts them to said set frequency point and emits them, thus, the radio signals transmitted between the base station and the playover station work on said set frequency point and said network includes a base station working on set frequency point and a playover station for frequency transformation.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to wireless network coverage technology, and discloses a method for area coverage of wireless signals and a wireless access network for realizing the method. Background technique [0002] At present, when mobile operators provide broadband services through the third generation mobile communication system (3G, The Third Generation), one of the difficulties they face is the problem of indoor coverage. Usually, the method of using outdoor base stations to cover indoor scenes is very difficult and complicated in technical implementation. It cannot provide suitable wireless signals for indoors to realize indoor wireless broadband services. In order to solve this problem, the scheme of adding transmission units or increasing the number of repeaters in the room is generally adopted at present. The specific methods include the following four types: [0003] The first method is to build ...
