System Description
The office building has strong shielding. In order to solve the problem of blind spots in wireless intercom signals on each floor and pass the acceptance of the radio management bureau, a distributed networking solution must be adopted. After on-site investigation and testing, our company provides the following solutions to solve the communication problems in your main work area and meet the relevant requirements of the radio management bureau for reference:
Using the relay station's inter frequency communication method, the communication distance of the handheld walkie talkie is extended. The relay station uses one Motorola relay station, which has reliable performance and rich functions< br /> Install duplexers inside the relay station 2, sharing a single antenna for transmission and reception to save costs and eliminate interference between signals< br /> Three antennas will be used, with one installed on the north and south sides of the main building for outdoor use. High gain suction cup antennas will be used indoors, while high gain suction cup antennas will be used on the north side and high gain fiberglass antennas will be used on the south side. The reason for using different antennas is that there may not be enough space indoors to install fiberglass antennas, and there is no suitable place to install fiberglass antennas in the northern outdoor environment. This plan adopts simple distributed cabling to meet the requirements of the Radio Management Bureau that the signal field strength within 50 meters of your unit's area should be less than -105dB< br /> Considering the high usage of feeders, it is necessary to use low loss and high conductivity shielded cables to connect the relay station and antenna< br /> Five antennas are connected to each other using a power divider The office building usually requires the use of two communication systems, one for security and the other for internal communication, and then a combiner is used to merge them. The Motorola type relay station selected in this plan can use one system to meet the usage requirements of two departments. This allows for the use of one host, one antenna, and one feeder, saving costs and eliminating interference issues between the two systems< br /> Motorola's hardware design is to have multiple channels on the same frequency, with a maximum of 16 channels that can be distinguished by audio compression. Therefore, one system can provide two relay channels for your company< br /> Two channels use the same frequency, which can save a set of frequency occupation costs and facilitate frequency application at the radio management bureau; By using relay channels, the blind spot problem of handheld walkie talkie communication is basically guaranteed< br />
