It is often inconvenient to manage places that need to use multiple full-band signal blocker. There are too many full-band jammers, and daily inspections are also a relatively large workload. From the perspective of customers, to facilitate customer management, topsignaljammer Technology Co., Ltd. has launched different full-band signal jammer systems, which are divided into power carrier plus 433MHz wireless management system and TCP/IP protocol management system. So what do these two management systems have in common?

1. Control functions, including the remote switch control of the full-band shielding instrument through software, and the timing switch of the full-band signal shielding instrument according to the set schedule. These most basic control functions are relatively simple to complete , and this function is also essential.

2. Check whether the full-band signal shielding device is faulty. The administrator checks the working status of the full-band signal shielding device through the software. The system of the full-band signal shielding device responds to whether there is a fault. It can also complete independent detection, and then generate a detection log for easy management. In the later stage, the staff will generate a form through the full-band shielding system to check whether there is a fault in each full-band signal shielding device. If there is a fault, it will be repaired in time to ensure the continuous and stable operation of the full-band shielding system.

3. The most common function of the full-band signal jammer system is to complete the adjustment of the transmission power of each frequency band module of each full-band jammer. This function is necessary in some places, such as prison units and school units. Wait, if there is a residential area around a unit, or a center with frequent personnel activities, and multiple full-band signal jammers are used in the unit, it will have more or less impact on the surrounding residents. In this case, the function of adjusting the transmission power of each module (adjusting the shielding range) is particularly important. It can reduce the transmission power of the shielding module for the full-band jamming instrument near residential areas, and make the full-band signal jamming instrument to the outside world. Minimize the interference to ensure that the signal in the venue can be effectively shielded, and the interference to the outside world is minimized.

The South Korean Ministry of Science, Technology and Information and Communication Technology said that the spectrum will be activated on December 1. The 3.5GHz spectrum will be available for 10 years and the 28GHz spectrum will be available for 5 years.

Keysight Technologies recently revealed that it has signed a Memorandum of Understanding (MoU) with Korea Telecom to jointly develop 5G New Radio (NR) technology and evolved version of 4G technology to accelerate the commercial deployment of 5G.

The signing of the MoU indicates that the two parties will deepen cooperation in the development of 5G NR and evolved 4G technology, and drive KT's 5G trial and commercial deployment process. Keysight will share its experience in 5G NR technology development, 5G infrastructure testing, and user equipment testing in Sub-6GHz and mmWave bands. Keysight will support the development of over-the-air (OTA) and mmWave beamforming calibration test methods, which KT will use to develop associated test procedures.

The two parties will work together to accelerate the evolution of 5G NR test and measurement solutions (including 5G network and user equipment emulation solutions that were launched earlier), including early R&D testing in the ecosystem and verification and performance testing of equipment and networks during actual deployment. KT will also use Keysight's 5G NR software solutions throughout the product design cycle, taking advantage of its advanced capabilities such as simulation, signal generation and analysis. In addition, Keysight's solution for the evolved 4G configuration provides features such as multi-band, multi-carrier aggregation and higher-order MIMO, which can help Korea Telecom transition from 4G to 5G signals more smoothly.
