Embodiment Construction

[0040] The method of the invention avoids the frequency spectrum resource used by the existing wireless access network by using 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 access 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...

Abstract

The invention discloses a method for regional coverage of wireless signals and a wireless access network for realizing the method, which are used to solve the problem of relatively large interference to signals outside the region and high coverage costs when the existing wireless access network performs regional coverage question. The method includes: the base station transmits a downlink wireless signal at a set frequency point other than the frequency band occupied by the wireless access network, and receives an uplink wireless signal; the repeater receives the downlink wireless signal of the base station, and the downlink wireless signal Convert the working frequency to within the frequency band occupied by the wireless access network and transmit, or receive the uplink wireless signal transmitted by the terminal in the frequency band occupied by the wireless access network, and convert the uplink wireless signal to the device and transmit at a fixed frequency point, so that the wireless signal transmitted between the base station and the repeater works at the set frequency point. The network includes a base station working at a set frequency point and a repeater station for frequency conversion.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to coverage technology of a wireless access network, 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 ...
