Multi-Point Digital Link (MDL)

General 
The MiMOMax Network Digital Link (NDL) and Multi-Point Digital Link (MDL) is a family of software flexible, low latency, digital radio links designed for providing mission critical linking for, DATA SCADA and back- haul type applications  

The MDL product family utilises licensed narrow band radio channels and MiMO technologies in 2x2 and 2x4 MiMO configurations to provide industry leading spectral efficiencies of up to 12.8 b/s/Hz or greater enabling raw data rates (including link overhead ) of up to 320kbps in 25Khz channels.   

Utilising licensed spectrum ensures that the link operates in an interference free environment and is capable under right conditions of providing a reliable low-error data transport service (<1x10-7 bit error rate) over long distances.  For data and voice linking applications the MDL will provide a number of industry standard data interfaces at link end points.
 
MDL
The MDL solution describes a radio network that consists of one or more Base Radio Units (BRU) providing reliable duplex point to multi-point communications with a number of Remote Radio Units (RRU) throughout a design coverage area.
 
High performance multi-access protocol provides rapid access to the system by RRU’s  A MiMO antenna (or antennas) provides both vertically and horizontally polarized signals at each ends of the link to provide a high performance and diverse MiMO link over up to 64km with some near line of sight and non line of sight capabilities over shorter distances.

The addition of a second optional diversity MiMO antenna and receiver, operating in a 2x4 configuration may be used to provide additional link robustness. A number of interfaces are available to support various applications and the system is capable of simultaneously supporting remote outstations on different modulation schemes to accommodate various data rates and link paths.   A specific high quality site interface card supporting up to 6 x 32k ADPCM audio channels plus a signalling channel is available to support analogue interface requirements. 

With these applications in mind the MDL is designed to have ultra low latency and low jitter and fit into the usual channel allocations allocated to fixed radio links.  Multiple links can be cascaded or combined with NDL’s to cope with difficult terrains or very long links.  Download complete data sheet at.
