solution employs a sophisticated bandwidth management capability to maintain Service Quality.
The signaling and O&M traffic is always protected from being dropped in case of WAN
congestion – this ensures that the BTS/NodeB stays connected and synchronized. The
bandwidth manager
the available WAN capacity – this mechanism maintains good voice quality while effectively
reaching the optimal target optimization rate.
Comtech EF Data's patent pending algorithm on voice packet discard is designed to minimize the
impact on the voice quality. This results in superior voice quality and improved Service Quality
even at peak hour traffic load. Implementing a RAN optimization solution without such
capability serves little purpose.
