Investor’s primary concerns in adopting new technologies is the cost of deploying and operating the systems in terms of capital (capex) and operational (opex) expenditures, as well as the time taken to see a return on investment.
Investors are always challenged to address the changing needs of technology and customers while fulfilling their own goals, since changes necessitate system upgrades, and updating inflexible existing systems might jeopardize an investor’s financial aspects.

By dramatically improving throughput and communication quality through the use of MIMO antennas and beam-forming algorithms, 5G wireless technology has been able to achieve its one of the key objectives. With MIMO it is possible to achieve the higher throughput by combing the signal collected from multipath as shown in figures. Digital beamforming helps in improving the signal quality by combining the multipath signal and generates beam patterns required to mitigate the interference.
Faststream Technologies Active Antenna System (AAS) improves the radio quality and realizes the stable quality of service by full digital beamforming technology.
Fastsream’s Sub 6 GHz Massive MIMO with fully digital beamforming is ideal for improving coverage and capacity in densely populated areas.
Sub 6 GHz has wider coverage than that of mmWave, and in order to improve radio quality, it is essential to control its coverage and mitigate interference, by inserting the product horizontally into buildings.
mmWave secures a wider bandwidth and have a high traffic capacity. Utilizing this feature, the installation of mmWave is primarily anticipated in city centers to strengthen the network in specific areas where traffic is concentrated by dense population. However, mmWave radio waves suffer from high propagation loss and are not appropriate for long-distance transport.
In order to provide adequate coverage, numerous pieces of equipment must be installed at numerous locations close to end users, such as street furniture where there is a severe lack of space. The mmWave Massive MIMO RU from Faststream is made small and light, which makes installation easier, increases the number of possible sites and lowers operating costs with its low power consumption feature.
