The lower a frequency, the longer its range. That is why 700 MHz will be key in the expansion of 5G. However, the middle band between the 3,4 y 3,8 GHz is playing a key role at present, since it is where 5G signal is being deployed and emitted at present by the large operators in Spain.
Double the frequency per antenna – faster deployments
Now, at these mid frequencies, Samsung has developed a new radio technology which increases the bandwidth available to operators, increasing the capacity and speed of 5G deployments, and improving the user experience.
Thus, currently, the bandwidth used by 5G antennas is 200 MHz, but Samsung’s innovation will double that figure to 400 MHz. With this, it is possible to maximize the utility of the mid-frequency bands using less equipment.
Among the situations in which this is a great advantage we find, for example, when an operator has 400 MHz of non-contiguous bandwidth. Besides, it is also a great solution for the RAN, where one operator shares infrastructure with another. Thanks to this, where there was now one operator per antenna, now there can be two using the same antenna and the same 200 MHz spectrum as before.
If we take into account that operators currently have almost 400 MHz of spectrum between 3.4 and 3.8 GHz, we have that all operators can offer 5G using the same antenna, something ideal to accelerate deployments in towns and areas where there is only an antenna.
The first compatible antennas will be on sale in 2022
This improvement will only apply to the mid-frequencies, which currently offer the best balance between speed, range and low latency, key characteristics of 5G. The first commercial devices with this technology will be available early 2022.
Samsung recently announced another upgrade to 5G called Mobility Enhancer. This AI-based technology improves beamforming performance in 5G antennas, being able to direct the signal more efficiently towards mobile devices and improving performance by 30% in antennas with the same characteristics.
Thus, Samsung continues to demonstrate that it is one of the most advanced companies in terms of 5G, where the company already has hundreds of millions of devices and products in the world that have this key connectivity for the coming years.
