It is a very wise approach to avoid being interrupted by suddenly ringing mobile phones during meetings, or to keep attendees focused on the meeting content and prevent it from leaking out.However, if you are concerned about the appearance of the meeting room and do not care about subtle cost differences, you can also choose a fixed mobile phone jammer with an internal antenna.Excluding intentional damage, if fixed in one location, this type of conference room phone signal blocker with an external antenna would have a better effect, easier troubleshooting, and often lower prices, making it relatively economical.
You can also download some auxiliary software, such as cellular, to check the signal status of the base station; If none of the above is true, the signal strength can be preliminarily determined by observing whether there is a communication base station nearby, the distance from the base station, and whether there is signal distribution in the conference room; The observation of signal strength is mainly used to select a mobile phone signal blocker with appropriate power.In addition, the built-in antenna is more aesthetically pleasing than the external antenna, and installation in a conference room will not feel awkward.
Whether there are wall partitions in the meeting room, whether the room is large or small, is also an important factor in choosing a mobile signal blocker.If the antenna is damaged, the signal blocked by the mobile phone signal blocker cannot be transmitted normally, thus losing the function of blocking the mobile phone signal.The advantage of choosing a built-in antenna is that if the phone jammer is fixed in the conference room, the built-in antenna has better resistance to damage than the external antenna.Therefore, we generally recommend using a fixed mobile signal jammer in the conference room.
Its advantage is stable interference performance and long interference distance.Overall, the above two factors determine the power selection of the conference room mobile signal blocker, which is also the first factor to consider when selecting a blocker.According to the style selection of mobile phone jammers, mobile phone jammers can be divided into portable jammers and desktop jammers, built-in antenna jammers, and external antenna jammers.The advantages of choosing a portable jammer are convenient mobility, portability, and strong maneuverability; The desktop jammer is fixed in a certain position, just like a WiFi router, and it is not recommended to move it frequently.
The external antenna is exposed, making it easy to accidentally bump the antenna during the transfer process.Like WiFi, blocked signals weaken when passing through walls; Generally speaking, for conference rooms without partitions, it is relatively easy to install mobile phone signal isolators; If there are partitions, it is necessary to consider adjusting the angle of shielding placement or using multiple shielding devices to cope.A small accessible conference room with an area of 20-50 square meters can usually be handled with a low-power jammer.
In summary, in terms of performance and price, choosing a mobile phone jammer with an external antenna is more suitable for meeting rooms.Choose to use a mobile signal blocker in the conference room.The so-called signal strength refers to the strength of the base station signal that a mobile phone can receive in a conference room, which can generally be measured using a spectrograph; Ordinary users do not have such measuring equipment.If the signal is normal, a low-power mobile phone signal blocker can be used; If the signal is too strong, a high-power signal shield needs to be used.
