Field of Invention

The engineering relating electrical communication engineering and

telecommunication engineering, in particular to the tower mounted booster for a base station.

Background of the Invention

The tower mounted booster for a wide coverage area base station is an electronic and electrical arts that is implemented on the mobile networks in all frequency bands and all systems, such as 2G, 3G, 4G or 5G, without the limitation to any one of the frequency bands. The said invention is provided to be used with base station equipment to amplify the frequency signals, whereas both of the uplink and the downlink frequency signals are amplified to increase the power, wherein the said tower mounted booster for a base station of the prior arts available will combine the frequency signals of both the uplink and the downlink and send them into the same antenna terminal for the ease and convenience of the installation thereof However, with that configuration, noise will be generated over the downlink and then transmitted into the uplink, directly affecting the efficiency of the tower mounted booster for the base station.

The components according to the prior invention is shown in Fig. 1 illustrating a tower mounted booster of lTx/2Rxtype and Fig.2 illustrates a tower mounted booster of 2Tx/2Rx type that combines the uplink and the downlink 45 altogether by connecting them to the base station 44 through terminals 47, 48 at least at one location. Inside the base station, there are provided receiver modules or low noise amplifiers (LNA) 57 , 58 functioning as an uplink, and a power amplifier module or multi-carrier power amplifier modules 59, 60. The two said components are assembled with signal guiding and blocking units 55, 56. Further, the said components also provide signal guiding and blocking units 61, 62 at least at one location and RF switches 5 1 , 52, 53, 54 at least at one location. Those said components are provided for receiving and transmitting frequency signals in the same terminal of the antenna via terminals 49, 50 at least at one location to antenna 46 With the signal guiding and blocking units 7 , 8 for demodulating the signals, the isolation Tx/Rx between the uplink and the downlink is about 90 dBs. When the power of the downlink is above +46 dBm (+46 dBm) or 40 Watts, the power of the generated coupled signal is approximately -44 dBm, causing the uplink or low noise amplifier (LNA) to amplify the said signals, resulting in the interference of the sideband noise and the power of active inter- modulation being above - 90 dBm, interfering the uplink signal channel, wherein the receiver Sensitivity is below -1 15 dBm.

Another problem with the device according to Figs. 1 and 2 is the thermal noise. That is, when the temperature of the uplink module or the low noise amplifier is increasing, it causes higher noise as well. The increased temperature is caused by the downlink since the component set in the downlink cannot convert the electrical energy into radio frequency power at 100% of full scale. As a result, surplus energy is produced, causing heat accumulation within the enclosure of the component set. In particular, in the geographical areas located near the equator, the average daytime temperature in summer is in the range of 35 40 degrees Celsius This sometimes causes the temperature inside the enclosure higher than normal or above 50 degrees Celsius, resulting in the higher thermal noise and the malfunction of the uplink or the low noise amplifier

As aforementioned, when the devices transmit frequency signal to the devices of the base station, the received signals will be mixed with the noise, resulting in the degraded efficiency in signal decoding of the base station. When the amount of the noise increases, the coverage area of the mobile networks or the receiving networks become less. As a result, a tower mounted booster for a wide coverage area base station is developed to reduce the signal noise on the uplink, to be in par with applications, in order to make a high efficient base station and to increase the coverage area Summary of the Invention

The tower mounted booster for a wide coverage area base station is a device used as a supplementary installation with the devices of the base station. It is to make the base station efficient in increasing the coverage area. It is a device of the type transmitting data on both the uplink and the downlink at the same time (Frequency Division Duplex: FDD) It also helps in solving problems and facilitating the usages by the target clients and reduces costs, on the service operator side, of the installation of more base stations in the areas where the frequency signals of the networks cannot be reached. Moreover, it can enhance the quality of the signals for the network users, enabling them to receive and transmit data in a better quality and improved efficiency manner. This, in turn, makes the users satisfied with the service provided by the operators of the mobile networks and other networks. On the service operator side, the delivery of their services can be fast with less costs. The present invention separates the uplink and the downlink apart by using the band pass filter and separate the uplink and downlink antennas. The components of the present invention produce the total isolation Tx/Rx of more than 130 dBs to reduce the amount of frequency signal from coupled signal of the uplink down or below -84 dBm. To enhance the efficiency of the signal improving devices, thermal noise has to be reduced by separating the uplink and the downlink apart to reduce the heat of the uplink or low noise amplifier (LNA) caused by the lost energy of the downlink amplifier module.

The tower mounted booster for a wide coverage area base station according to the present invention comprises a base station connecting to the tower mounted booster for a wide coverage area base station that is separated into downlink that is connected with a transmit antenna, and uplink that is connected with a receive antenna, wherein the downlink at the entry point is provided with an input signal detecting unit while at the output point of the downlink, there is provided an output signal detecting unit.
