MDAS Multi-service distribution system breaks through the traditional coverage solutions, and it is widely used in the following scenarios:
1) Intensive buildings, narrow roads, mostly are weak cover areas
Macro station coverage is limited. The owners are sensitive to the traditional equipment and with a strong awareness of rights. The traditional way "RF cable + antenna" is difficult to implement
With the increase of 3G users, the pressure of internet quality is higher and higher, and users not only complain but also safeguard their rights. The construction of internet is facing a big challenge.
2) Streets/ Stores
The outdoor signal is better, while inside the store is very weak.
About the traditional outdoor construction, it is difficult to coordinate all owners.
A lot of mobile phone users; huge mobile traffic; High requirements of data service
3) Hotel/Office/Apartment
Antenna is difficult to deploy according to demand. Traditional distribution system could only cover the public area. Even though antenna points install inside the room,it is still difficult to control signal leakage.
Low floors of the buildings: multi-partition wall, entrance and corridor have good signal, the signal inside room is bad
High-floor of buildings: outdoor BTS has a strong signal, difficult to control the Ping-Pong effect and pilot pollution problem
Property coordination difficulties
Antennas and RF cable laying difficulties, low property acceptance
Access lots of connectors and passive accessories, difficult to make sure the quality
Cloth coaxial cable construction difficult, long duration
Management and maintenance difficulties
Feed, power cables easy to be stolen
Passive node is difficult to monitor and maintain, the investigation difficult
Features of MDAS solution
Cable / fiber optic transmission medium, hidden construction, reduce property difficulties to coordinate
"Low-power, multi-antenna" way to achieve fixed / exact cover
RF unit close to the client, improving SNR, promoting system efficiency
Full network monitoring, maintenance and optimization to improve efficiency
Port to port design, system tuning, debugging and optimizing convenience
Multiservice solution
Reduce the requirements of multi-service for passive accessories
