Not anymore will network capacity and cost be a major concern for the wireless network system. A new method has been developed by the Researchers at the National Institute of Standards and Technology. This method will aid the evaluation and selection of optimal antenna designs for fifth generation (5G) devices and base stations alike.
Of course, the method will not only reduce the cost of the 5G network but also boost the network capacity.
The solution utilizes narrow beams rather than the conventional omnidirectional (360 degrees) antenna. The antenna is often crowded and its transmission loses a lot of energy leading to weak signal strength. However, the narrow pencil beam used in the solution ensures that signal interference and delays, as well as energy loss during transmissions, are reduced.
The NIST team was able to develop the method through the use of a special robot. The robot was loaded with a customised loaded sounder and other equipment to collect experimental data in the lobby and hallway of a NIST research building.
The result is that narrow beams are the solution, and a confirmation is in its RMS which showed delay spread dropping from 15 nanoseconds (ns) to about 1.4 ns. The method also gives an engineer the freedom to select an antenna that best suits an application.
It is believed that future research will extend the usage of the method to other different environments.
