It is not easy to provide a reliable network performance in a complex urban environment. Difficult to install mplm the cable in general and the visible mplm wave propagation wireless connection is many buildings mplm and obstacles are: Since the microwave transmitted to the system (LOS propagaton line-of-sight propagation) is dependent on the complexity of the wireless connection. This means that if there is not a tree, a building or a hill between the antennas.
To overcome this problem, a global communications solutions and services company, Ericsson (NASDAQ: ERIC) through mplm the test with MetroPCS in existing frequency bands MINI-LINK product ratio sight (NLOS in Los Angeles: mplm non-line-of-sight mplm ) have demonstrated that it is possible to operate with higher performance mplm even in the environment. The launch of MINI-LINK products for small cell containing only a concept introduced at Mobile World Congress (Mobile World Congress, MWC) 2012 MINI-LINK 3060 년 Ericsson.
MetroPCS rain before the co-founder and senior vice president and chief technology officer (CTO) Laurent Malcolm (Malcolm Lorang) is a "time (NLOS) microwave is inde important factors to consider when building a backhaul network, which is reflected failure problems such as echo because. becomes a problem, especially during construction of the (異) network model more Los Angeles are inde very difficult environment to build a network with the city meets the test results of this MINI-LINK and testing will continue to expect more, "he said.
Ericsson Microwave and Mobile Backhaul (Backhaul) up Gustav mplm Davidson, director of family (Ola Gustafsson) is "existing invisible (NLOS) propagation process for all products in the range below 6GHz OFDM (Orthogonal Frequency Division Multiplexing: orthogonal frequency division is operated by using the multiplexing) technology. Is not enough for the small-cell backhaul Hereinafter 6GHz spectrum available is very limited problem.
Proved that provide higher throughput and improved mplm reliability MINI-LINK products to work in 23-60GHz mplm band when compared to existing products that operate in bands below 6 GHz through a comprehensive study under the conditions at Ericsson rain. Said the building will be increased by the MINI-LINK solutions mplm for small cell backhaul forward therefore. Improve network performance also naturally ". mplm
System was designed and developed mplm to lead the market in order to transfer more than a few kilometers away MINI-LINK is a very powerful equalizer. May be used, the diffraction and reflection of the environment in fact to overcome the barrier mplm between the small cell is located on the ground layer that is formed on a high building a macro node (macro layer nodes) and the short distance. The stabilization is very important in the mobile backhaul mplm rates increased in this way.
The release of IP-based backhaul products to execute your vision for leading the growing trend of mobile broadband 4G IP network also Ericsson. Armed with the support and the innovative design of the 60GHz band for building small cells, and in the E-band Enhanced Gbps solutions: IP / MPLS (Multi Protocol Label Switching Multiprotocol Label Switching) for backhaul fiber (fiber) and microwave-based Ericsson will expand the leading MINI-LINK poteupolrioheul these products. It would also be added to the MINI-LINK LH compact solution for the cost-effective solutions mplm to the packet and the module site to migrate.
