Will 5G Safe in order to Use at home?
If you're wondering whether 5G is safe to use, you've arrived at the right spot. Focused energy from digital beamforming or 3D-scanning is no more harmful than 4G or 3G and it poses no security or environmental risks. But, before jumping onto the 5G train, it's essential to know what this new technology does and how it operates.

5G is a method of concentrating energy using 3D as well as digital beamforming
Beamforming makes use of multiple transmit antennas in order to direct radio power into a small sector, which increases bitrate and SINR at the equipment used by the user. In 5G NR up to an arbitrary 256 transmit antennas can be used per BS (or base station). Massive MIMO antennas use beamforming in conjunction with spatial multiplexing. is 5g safe operate at frequencies below 6 GHz.

Beamforming techniques have been developed for mm-wave bands, that differ from conventional spectrum of bands ranging from 900MHz and up to 5 GHz. The short frequency of these waves implies that antenna arrays need to be compact. The beamwidth is also very small, allowing only about a hundred metres between the base station (BS) and the user.

It's just as dangerous than 4G or 3G
The latest 5G mobile cell network operates at higher frequencies than 4G and 3G networks. This allows more people to simultaneously connect to the internet. It also enables these waves to travel shorter distances in urban areas. However, 5G has also been associated with increased risks for health issues, such as cancer. However, it is the World Health Organization has determined that there is no proof that 5G is any more risky than 3G or 4G.

The Federal Communications Commission (FCC) regulates wireless devices. While health and safety groups have interpreted some reports to suggest that wireless devices can cause cancer, there isn't conclusive evidence that 5G is any more or less dangerous. There is also no evidence to suggest that there should be an additional threshold to stop cancer from forming. Even though mobile phones are known to emit radiation, they don't cause the same amount of damage as boomboxes, portable radios and TV sets.


It's non-harmful to the environment.
In recent years residential real estate developers have centered on environmental issues and have started implementing energy-efficient technology. These include wireless connectivity, smart windows, along with lighting devices that use less energy when they are not being used. In 5G the efficiency of energy is likely to become a bigger issue. Companies are working to make 5G as green as is possible.

However, the latest technology could still have negative effects on the environment. For instance, the introduction of 5G will require removal of older smartphones, creating massive quantities of electronic waste. This waste could harm ecosystems and alter natural cycles. Additionally, the frequency of 5G may alter the circadian rhythms of animals that regulate reproduction and sleep. A study has shown that sparrows exposed to radiation from cell towers for between five and 30 minutes produced eggs that were deformed. In a different study, which was conducted in Spain researchers discovered that wireless frequencies disrupted the habits of breeding birds and affected their navigational systems.

It's an issue for security
FiveG-based networks represent the next phase in wireless technology. although this technology comes with advantages but it comes with serious security concerns. First of all, 5G does not use central hardware-based switching but uses an open software that defines routing. This means that there are fewer centralized points of control for hackers. This means that if a skilled hacker finds an avenue to access these networks, they could cause chaos. Some 5G security vulnerabilities are also user-facing because millions of devices are expected to connect to networks. This means that users and businesses must be prepared to protect the devices from the beginning.

While 5G promises faster speeds and less latency, security experts recommend be cautious when implementing the technology. They are concerned that 5G networks could be vulnerable to security weaknesses which could increase the severity of known attacks, and resulting in new ones.
