In addition to officially approving the new IMT subject of 6GHz spectrum, WRC-19 also officially divided 26GHz, 40GHz, 47Hz and 66Hz into IMT spectrum, which will greatly promote the coordinated development of 5G network high, medium and low frequency bands and accelerate the construction of 5G network. 5G global commercial deployment. In addition, WRC-19 confirmed at its next meeting discussions on the possible future use of the TV broadcasting spectrum (470-694 MHz) for mobile technologies.
Mobile cell phone signal jammer As the core resource for the development of mobile communication technology, spectrum resources are precious and scarce. Spectrum planning is the starting point of the industry, and will also determine the development direction, pace and pattern of the industry to a large extent. WRC-19 reached a series of consensus and resolutions on 5G spectrum, which will further accelerate the commercialization and development of 5G worldwide.
Signal jamming devices transmit on the same radio frequencies as cell phones. It interrupts the communication between the phone and the base station in the tower. Jamming is also known as a denial of service attack because it denies radio signals to users within the coverage area of the interfering device. Currently, there are different types of cell phone signal jammers on the market.
Some devices can only block one frequency, while others can block multiple types of networks at the same time. The latter can automatically switch from different networks to find open signals. High-end devices can block all frequencies at once, while others can tune to specific frequencies. In short, they emit random static or noise at various frequencies and are strong enough that devices close to them cannot connect to the connections they should. It’s a bit like opening the hood next to the engine of a sports car and trying to talk to someone on the phone. Local noise becomes too strong,
