The signal jammer can block 5g. According to the 5G frequency band zoning, China Telecom and China Unicom mainly use 100MHz frequency band resources in the 3.5GHz frequency band, and China Mobile mainly uses 160MHz frequency band resources in the 2.6GHz frequency band and 100MHz frequency band resources in the 4.9GHz frequency band.
1. The working principle of the signal jammer is to use more output power to release stronger signals in the corresponding frequency range of the mobile network to suppress normal interference signals, thereby achieving the purpose of blocking malfunctions.
2. A doctor at the School of Microelectronics, also said that communication technology is constantly upgrading, and the 5G signal system is also different from the original 4G system. It may also be common that older audio equipment cannot completely affect 5G signals.
3. Currently, mobile phone wireless network signal jammers on the market are mainly divided into 5G versions and non-5G versions. The 5G wireless signal jammer can block 2.3.4.5G mobile phone wireless network signals in the full frequency band, while the mobile phone wireless network signal jammer without 5G can only block 2.3.4G signals.
4. According to online shopping customer service, shielding power will also affect the signal screen effect. In addition, the shielding effect of the shield is closely related to the signal strength on the field. If the signal strength is high, the signal may not be suppressed, so the disadvantages of a higher output power screen must be considered.
