CMR cable is Communications Riser cable. It is used in risers or shafts from floor to floor and only a riser or plenum (CMP) cable may be used for that purpose. Though CMP can be used in lieu of CMR, you cannot use CMR in a plenum space. CMR and CMP are fire resistance classifications. CM is for general purpose that may be used elsewhere not requiring special fire code considerations.
Riser
Cat6 is the current standard for new installations of ethernet cable. Depending on the space and certain building codes you need to decide between Plenum (CMP) or Riser (CMR). The difference being Riser cable is more durable, but puts out toxic fumes when caught on fire, so it is not suitable for spaces with open air flow. Dropped ceilings are generally considered Plenum spaces so therefore require plenum cable.
