M3 is especially tailored to provide a comprehensive and flexible coverage solution in complex coverage environments like densely populated residential area, underground areas. Tunnels, stations and terminals, hotels, meeting rooms··· ··· widely used on the mobile communication not works. The 1800M band can support DCS/LTE, and the 2100M band supports WCDM/LTE.
Our M3 system support multiple systems & services access.We can support 2G,3G,4G services in one system. Greatly avoid duplicate construction.For M3 system ,we have several advantages to introduce:
(1)M3 system is full optical distribution system, only use optical fiber as transmission medial,very easy to deploy.
(2)With our M3，compared with traditional IBS solution, there is no complicated project design for each link. As we use optical fiber as media ,the output power utilization almost reach 100%.without too much power losses.
(3)M3 solution does not use any passive component(like the couplers, combiner, splitters),it’s a complete end to end solution, our NMS can monitor the whole system、every unit without any blind area. Maintenance is very convenient.so with these advantages, our M3 system can help our customers to save budgets and greatly reduce the Project schedule.
This is the network diagram for M3 system:
MU to EU ,EU to RU all use optic fiber as transmission media.
(1)One MU have 4 optic interfaces which connecting to 4 EU by star network.
(2)One EU can support connection to 8 RU at the same time.
EU can support cascade connection to extend network. The system allow maximum 8 EU connect to each other.
So according to this architecture, Our M3 system can support 4*8*8=256RU theoretically.
Considering the influence to BTS by NF, We suggest the number of RU not more than 48 with 27dBm output.
