Question: Is it possible to daisy-chain the Snom M5 repeaters together? and if so, how many?

Answer: You can add up to 3 Repeaters to a base. 

When you add the M5s to the DECT chain you can select manual or local automatical. Choose local automatical so that the base can create the chain. The first M5 should use the base RPN as its Sync Source. The 2nd M5 should use the 1st M5's RPN as its Sync Source and the 3rd M5 should use the RPN of the 2nd M5 as its Sync Source.

Base/ RPN00 ----->> M5/RPN01------->>M5#2/RPN02-------->>M5#3/RPN03  

                                     ^                               ^                                     ^ 

                                     |                                |                                      |                           

                      sync source:RPN00      sync source:RPN01       sync source:RPN02


The base has an omnidirectional antenna with a theoretical indoor spread pattern coverage area of 50 meters. Coverage is dependant on the physical structures over the covered area. In some environments use of M700 bases may be needed when coverage cannot be achieved using M5 repeaters.
