Top advantages of
high-frequency electromagnetic waves
The millimeter wave frequencies,
commonly found between microwaves and infrared waves, are high-frequency or hyperfrequency
(hyperfrequence) electromagnetic waves that have the potential of providing
solutions to the ever-growing demand for high-speed and bandwidth communication
needs. Millimeter waves have a high frequency range of between 30 GHz and 300
GHz, which is also equal to a wavelength range of 10 mm -1mm. Over the years,
affordable and advanced technologies have allowed for proper use of widespread
millimeter waves. Through this widespread use, it has resulted in effective
expansion of fast data and wireless communication applications while at the
same time reduced the pressure on lower frequencies.
Today, data rates can now reach
speeds of up to 10Gbps. This is possible through applications such as
point-to-point broadband access and WLANS, wireless and mobile networks,
high-resolution video streams and automotive radar options among others.
Generally, there are many advantages of millimeter wave frequencies. First, it
should be understood that there is an increased demand for bandwidth due to the
increased number and use of different types of communication devices. This
means that meeting the worldwide communication needs and requirements for
high-speed data transfers through the wireless network possess some challenges
because of limited spectrum.
In order to address these
challenges, most applications today are now limited to frequencies of only 30
GHz. The 30 GHz frequency range is now congested thereby restricting the proper
exploitation of new technologies. The advantage, however, is that the hyperfrequencies
(hyperfrequences) wave spectrums, which were previously only reserved for
scientific and military applications, are now being availed for commercial and
consumer applications. With such a move, it can reduce the demand for lower
frequencies and at the same time allow for the proper exploitation of
frequency-dependent applications and technologies.
Besides the restricted allocation
of frequencies in the range of 30GHz to 300GHZ, in previous years, there have
not been many applications that work at such high frequencies. Currently,
however, many manufacturers are now producing applications and components that
have the capacity of handling the Millimetre wave (millimetrique). There are
many manufacturers who are today developing very affordable applications and
components that are progressively making the use of millimeter waves more
practical in different types of applications.
The introduction of newer
technologies as well as semiconductor materials like gallium nitride, indium
phosphide and gallium arsenide are easing the way for building components such
as transistors at submicron size. The transistors being built today are
actually smaller than 40nm. But despite the potential use and applications of
millimeter waves, the components being built today are very costly.
Manufacturing such small-sized components or transistors of 40nm and below
requires a lot of care and precision. These factors significantly increase the
cost of manufacturing these components.
