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

The invention discloses a area covering method of wireless signal, and a wireless access network for implementing the same, which is used to solve problems that the conventional network has large interference out of the area, and high cost when covering the area. The method includes that: base station sends downlink wireless signal at a set frequency point out of occupied band of mentioned wireless network, and receives uplink wireless signal; direct amplifying station receives downlink wireless signal of base station, converts working frequency of downlink wireless signal to occupied band of mentioned wireless network and sends it, or receives uplink wireless signal sent by the terminal in occupied band of the wireless network, converts the uplink wireless signal to the mentioned frequency point and sends it, thus, wireless signal transmitted between base station and direct amplifying station works on the set frequency point. The network includes base station working on set frequency point, and direct amplifying station carrying out frequency conversion.

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 ...
