MicroStation is needed in 5G Era
"4G changes life and 5G changes society". Since the official launch of 5G business in China last year, people are full of expectations for 5G.
As we all know, 5G has the advantages of enabling thousands of industries. The three scenarios of 5G(including eMBB, URLLC, and mMTC) are applied in fields such as driverless driving, industrial Internet, distance education, and telemedicine.
5G is mainly reflected in network capability, including transmission rate and delay. For the deployment of 3.5GHz band, the passive compartment may not meet the needs of 5G deployment and 5G services.
The advantages of 5G small base station are prominent. As an effective extension of macro base station signal, it enhances the network coverage ability, and combines with MEC and other technologies to become the best solution for indoor and outdoor coverage.
MicroStation "big function"
The millimeter wave band adopted by 5G is distributed between 2515MHz and 4900MHz. The higher the frequency, the shorter the wavelength and the weaker the diffraction ability, the smaller the radiation range when encountering obstacles.
5G "MicroStation" came into being, filling the gap of "macro station", playing the role of "relay", forming a full coverage of the whole network. The "body" of the "MicroStation" is smaller than that of the macro station, and its transmission power and coverage are also smaller than that of the macro station. The MicroStation spacing will be reduced to 10-20 meters (compared with the spacing of at least 500 meters between the macro stations).
As the three major operators accelerate the large-scale construction of 5G network, the number of MicroStation will usher in a period of large-scale development!
As a professional power supply manufacturer, Evada has crossed from PHS, 3G, 4G wireless communication power solutions to the 5G era. Evada power has accompanied the development of China's communications! Evada independently researched and developed integrated power supply / blade power supply (AC to DC) for 5G MicroStation, outdoor cast aluminum natural heat dissipation, IP55 protection grade, high efficiency and energy saving, convenience and simplicity, configuration of lithium battery energy storage, modularization, flexible expansion and other characteristics. It can be installed in a variety of flexible ways, such as pole, flag, wall hanging, etc., and can be quickly deployed without land occupation and less engineering exploration. It can be applied to all kinds of outdoor scenes to escort the rapid coverage of 5g network.
