Two purpose electric appliance for lighting and communication

Abstract

This invention relates to a double-use appliance in illumination and communication including an illumination electric appliance and a radio communication base station antenna, which is composed of a transceiver and an antenna, the base station antenna takes illumination appliance as the carrier and integrates them together, in which, the transceiver is parallel to the illumination appliance, which can be various illumination lamps, the transceiver can be integrated in the illumination device or out of it and the antenna can be set in or out of the illumination device, which solves the problem that it is difficult to select addresses for base station at present and shortens the distance of access points and mobile stations.

Description

technical field [0001] The utility model relates to a lighting and communication dual-purpose electric appliance, which belongs to the field of wireless communication, and relates to a wireless communication base station antenna technology with lighting appliances as carriers. Background technique [0002] The existing wireless communication base station antennas are mainly built on the roof of high-rise buildings. Taking a CDMA base station as an example, the average transmission power is 0.25W and the coverage radius is 100m to 500m. The antenna is mostly made of copper or copper alloy, and its shape is mainly straight line and flat plate. [0003] Traditional base station antennas have many problems: [0004] 1. Since there are already various base stations on the roofs of urban buildings, it is difficult to select new base stations for network optimization. [0005] 2. Since the average distance between the traditional base station and the mobile station is 250m, the t...

AI Technical Summary

Problems solved by technology

[0004] 1. Since there are already various base stations on the roofs of urban buildings, it is difficult to select new base stations for network optimization

[0005] 2. Since the average distance between the traditional base station and the mobile station is 250m, the transmission power of the base station and the mobile station are relatively large

[0006] 3. Due to the large coverage of traditional base stations and the complex terrain of buildings, the signal attenuation in some places may be large

[0007] 4. All kinds of base stations affect the image of the city

[0012] 1. If infrared is used as the signal carrier, infrared can be divided into the following three bands in practical applications: near infrared: wavelength 0.77 ~ 3.0 μm, mid infrared: wavelength 3.0 ~ 30 μm, far infrared: wavelength 30 ~ 1000 μm, The wavelength of GSM or CDMA (if both use 1.8G as the carrier) is 16.7cm, so it cannot be used for current GSM or CDMA wireless communication

[0013] 2. If infrared is used as the signal carrier, all existing base stations and mobile stations based on GSM and CDMA must be redesigned, and all equipment and algorithms will be discarded

[0017] The disadvantage of this method is that in a limited space, increasing the antenna to improve the coverage effect will inevitably affect the appearance and increase the difficulty of site selection for the base station
