The invention discloses a communication intelligent lamp post and a working method of the communication intelligent lamp post. The communication intelligent lamp post comprises a micro-station antennaand an intelligent lamp post. The micro-station antenna is arranged on the top of the intelligent lamp post and is connected with the intelligent lamp post through a prefabricated flange. The micro-station antenna is an LTE cluster antenna, and the LTE cluster antenna comprises a single-sector micro-station antenna, a back-to-back micro-station antenna, a three-sector micro-station antenna and anomnidirectional micro-station antenna. By the adoption of the communication intelligent lamp post and the working method, the conventional lighting function can be realized, meanwhile the functions of peripheral signal coverage, environmental monitoring, intelligent monitoring and the like can be realized, and at night, the light source opening and brightness can be adjusted through sensing equipment, so that the power consumption can be effectively reduced, and the energy-saving and emission-reducing effects of a street lamp are improved; moreover, conventional base station construction causes discomfort to citizens easily; the micro-station antenna is perfectly combined with the street lamp and is not likely to being discovered, and the concealment is improved; and meanwhile, the micro-station antenna relies on the street lamp as a carrier, and a communication cabinet is buried underground, so that compared with traditional base station construction, the station construction cost isgreatly reduced, and the beneficial effect is in line with the interests of municipal department.
