External 4G LTE Antenna  

With the information technology network, most people use cell phones, computers. So the internet is indispensable to us. In addition to the 4G, 5G networks that people usually use, many people have WIFI installed in their homes as WIFI is a more affordable and better signal. They also meet this problem is why the router signal poor?

Some reasons are that the router not be put in the right place, some are that too many people use it, crowded, or too many surrounding tall buildings, obstacles will affect the router to receive the signal, sometimes is too far from the signal tower.

You could install an outdoor MiMo 4G Antenna where there is a better signal and connect this to your 4G router indoors. 4G signal booster is an option depending on your environment.

We are a professional 4G antenna factory, there a variety of items for your choose.

Why does 4G lte antenna have different frequencies?

Co-channel interference:

Communication system, if the same frequency band at the same time to propagate non-orthogonal signals. The receiving device (the phone) will be difficult to distinguish the signal. The bit error rate will increase (that is, the call quality or transmission rate decreases).

An example, in human terms is that a road that holds only one person cannot run two people at the same time.

In order to solve the problem of co-channel interference, the simplest and most brutal way is to artificially define the spectrum. This has led to the emergence of official radio authorities around the world. Their mission is to prohibit spectrum misuse and to define the use of individual spectrums from a policy perspective. There are other solutions such as dynamic division – cognitive radio, find their own spectrum and access it themselves.

Spectrum:

The spectrum is a non-renewable and restricted resource.

The frequencies are different. The transmission characteristics of the electromagnetic waves are also different. For wireless communication, a lower spectrum means a longer wavelength. That the attenuation will be reduced when encountering buildings. The coverage will be increased with base stations at such frequencies.

TD-LTE and LTE-FDD

As mentioned above, in order to prevent co-channel interference. the Radio Board divided the frequency to three companies: Mobile, Unicom and Telecom, to support their respective users. TD-LTE is the 4G standard of Mobile, LTE-FDD is the 4G standard of Telecom and Unicom. These three belong to different companies. They need to transmit data to users through their respective user management systems. In order to avoid interference on the same frequency, so they need to be on different frequencies.

To avoid co-channel interference, we divide the spectrum to different communication methods and different companies. That is why 4G LTE has different frequencies. Different frequency bandwidths lead to different theoretical data transmission ceilings.

Can an LTE outdoor antenna be used in areas with extreme weather conditions? such as strong winds or heavy rain? and what precautions should be taken?

Yes, an LTE outdoor antenna can be used in areas with extreme weather conditions. Such as strong winds or heavy rain. Precautions should be taken to ensure that the antenna remains stable and undamaged.

Here are some precautions to take:

You can choose a sturdy mounting location that is safe from strong winds. for example, you can mount the antenna on a rooftop or a solid structure.

You make sure the mounting bracket is secured. That to prevent the antenna from falling or moving during strong winds.

Use durable cables that can withstand extreme weather conditions.

Consider using a lightning protection device to protect your antenna from lightning strikes.

You inspect the antenna and its connections to ensure they are in good condition. And replace any damaged parts promptly.
