5G Mobile Network

A New Era is here for a start with a bang. It is ‘The 5G Era’.

The 5G Era is considered to be an Era which would come with Numerous innovations and would take the world closer to the Robotics. A Glimpse of which could be witnessed now in Films and cartoon based on graphics. The inclination of the New Gen towards 5G is treme=The World’s biggest Powers are working day and Night to develop this technology to its best and are trying to create their 5G networks. The first commercial 5G-capable device has been launched by AT&T In US, named the Netgear Nighthawk 5G mobile hotspot. Talking about phones, the First 5G models are expected to be launched in the first half of 2019, i.e. we are not far off.

Thus, all those factors which would support the 5G technology are being studied upon and have been started to be implemented, viz. first 5G towers are beginning to go online. Much talked upon is that 5G will be capable of operating at much higher frequencies than current 4G LTE networks. Thus, some Customers look concerned regarding the safety purpose that whether the new technology 5G phone, would be safer at least as 4G which has been reaching to us.

Let’s Now Understand the 5G millimeter waves

So far, spectrum bands have been used by carriers anywhere from 600MHz to 2.6 GHz in order to deliver goods to us. This is the lowest microwave range. With the beginning of 5G, it is expected that some way higher frequency bands would be opened for service. This could include the millimeter waves which have been heard of sometimes. It is almost confirmed that some lower-frequency spectrum like T-Mobile’s 600 MHz or Sprint’s 2.5 GHz would be utilized for 5G transmissions. But at the same time it is expected that carriers will increasingly be taking advantage of higher bands, such as 3.5 GHz, 6 GHz, and even 30 GHz, and up! The 30 GHz is expected to sound too much. The millimeter waves actually begin here!

Still, it is unknown as to what band the AT&T’s Netgear Nighthawk 5G hotspot works on. AT&T informed that the device will be using millimeter waves. This is how we know the Nighthawk 5G, powered by Qualcomm’s Snapdragon X50 5G Modem. It would be cruising at or above 30 GHz.

Q. But the question arises that Why the millimeter waves are found in the range of 30 – 300 GHz.

Ans. This is because a wave with a frequency of 30 GHz has a length of approximately 10mm, side by side, a wave of 300 GHz has a length of 1mm. So, it could be said that even if some higher bands are eventually unlocked for 5G use even then the technology probably won’t exceed the millimeter range during its entire lifetime.

Now arises the Most important Question that whether this 5G millimetre waves safely?

Speculations and Rumours are both heard side by side every day and we all must have heard some sayings that these millimetre waves are of such high frequency that they could eventually fry our brain. But, Reality is something else! These waves, as high as 30 GHz, won’t be nearly powerful enough to do any harm to us and our brain.

The electromagnetic waves are unbelievable of higher frequencies and beyond a certain threshold, and they are something dangerous to Human beings but the good news regarding the use of 5G is that the Threshold limit is way far than 30, or even 300 GHz!

Now in order to know the actual threshold limit, we require to find out answers to some very important questions:

If we are talking about the Millimeter waves we must know that:

What lies there beyond millimetre waves?

It has now released a sense of relief as we now know that these new 5G bands of about 30 GHz or above are not powerful enough to do any harm to mankind. But now, we must know that;

What could be dangerous?

As we discussed and concluded that the millimetre wave range extends up to 300 GHz waves, which is the farthest range of the entire microwave. The wave that follows the microwaves is the infrared range, sometimes called infrared light. The infrared waves span the range of 300 GHz to 385 THz (Terahertz) and are invisible to the Human eye. The infrared waves have lengths from 1 mm (the shortest microwave length) to 780 nanometers (1000 nanometers equal 0.001 of the millimetre, just for orientation).

The Infrared radiation is used in many ways on Earth and is not considered to be of a dangerous type.

So, as these tiny waves get more and more intense, they eventually move into the spectrum and is said to be “visible light”. It includes wavelengths of 700 nm to 400 nm and frequencies of 430 THz to 790 THz. Better for the Human being that thankfully, the visible light spectrum is not harmful to us.

When do things get dangerous?

Lets now talk about, what would then be the Danger side?

The wave range that follows after visible light, falls into the harmful segment.

The wave follows, is the Ultraviolet! The spectrum features wavelengths ranging from 400 nm to 10 nm and frequencies from 790 THz to 30 Petahertz! (1 PHz = 1,000,000 GHz). The initial portions of the wave aren’t considered harmful, but the range in which this wave falls, it is here that we observe the transition from non-ionizing to ionizing radiation.

Ionizing radiation meant that the radiated particles have the energy to the extent that they can actually disrupt electrons from molecules or atoms and leading them to acquire a positive or negative charge. So, concludingly, somewhere within the ultraviolet spectrum is where things start getting dicey.

Above the ultraviolet range, there lies the x-ray range (10 nm to 0.1 nm / 30 Petahertz to 30 Exaherz). Everything ionizes above the ultraviolet spectrum and so the x-rays. Though, its small doses are used for our help and welfare through medical applications.

Finally, we would talk about the gamma rays (having wavelengths less than 0.1 nm and frequencies of more than 30 EHz). It has been known for its penetrating property and is harmful if not used in a controlled and constructive manner. They are successfully being used in the Medical fields and have applications in medicine and industry.

Radiation is categorized as per its being non-ionizing and ionizing. Non-ionizing types of radiation, like radio, microwave, infrared and visible light are considered to be safe. While the ionizing types, like ultraviolet, x-rays and gamma rays are potentially dangerous.

Apart from it being expected to employ a higher range of frequency than previous cellular technologies, 5G is still safe to be used and is within the confines of the microwave spectrum, including those millimeter waves. “Millimeter waves” are not going to be dangerous.

Thus, briefing and looking at all the aspects of the 5G implementation and its future with the Human beings, we should feel safe in this new 5G world that is about to occur and with a free mind and fully enjoying the quality of life improvements it could be considered as a part of our lives in the new Era.
