At present, 5G networks have been deployed on a large scale, and 5G base stations have been built on a large scale across the country. The corresponding 5G mobile phone signal jammers have also been continuously upgraded and iterated, adding the function of shielding 5G signals. Careful users may find that the new version of the 5G mobile phone signal jammer has more antennas than the previous shielding devices. So, why are there more antennas, and can the number of antennas be reduced?<\/p>\n\n\n\n

To understand the increase in the number of antennas in the current mobile phone 5G signal jammer<\/a>, it is necessary to take into account that the 5G communications of different operators use new frequency bands such as 700MHz, 3400MHz, 3500MHz, and 4800MHz, and some frequency bands have also been adjusted to better compatibility with 5G applications. For example, China Mobile’s 4G frequency band was originally 2555-2655MHz, and in order to meet 5G requirements, it has been expanded to 2515-2675MHz. In order to effectively shield 5G mobile phone signals, the new version of the 5G mobile phone signal jammer must add shielding modules for the newly added and adjusted frequency bands. Each module requires an independent antenna, and the original 2G, 3G, and 4G shielding modules and antennas must also be retained. In this way, the total number of antennas can only increase.<\/p>\n\n\n\n

Can 5G mobile Cell Phone Jammers<\/a> reduce the number of antennas? One method is to combine the output signals of the selected shielding module with a combiner, and then transmit the shielding signal through an antenna. The combiner can be two inputs and one output, or three inputs and one output. But there are two disadvantages to using a combiner. First, the bandwidth of the combined shielding signal will be wider, which will require higher antenna standing wave performance and affect parameters such as standing wave ratio; secondly, this method increases the hardware cost, and the cost of a single antenna is significantly lower than that of a combiner.<\/p>\n\n\n\n

In summary, considering the production cost and technical indicators of the shielding equipment, most 5G mobile phone signal jammer<\/a> manufacturers will give priority to using one shielding module for each transmitting antenna, unless the customer has special requirements, so reducing the number of antennas is not a top priority at present.<\/p>\n\n\n\n
