• Service-driven adaptive modulation: fully exploits the air bandwidth in its entirety
by changing the modulation scheme according to the propagation availability and
allocates transport capacity, discriminating traffic by different services, which is only
possible in a packet-based environment.
Multiservice aggregation layer
The 9500 MPR aggregates and carries over a COMMON PACKET LAYER: TDM 2G, 3G,
LTE and IP/Ethernet. This allows sharing of common packet transmission infrastructures,
regardless of the nature of the traffic being carried.
Due to the nature of Ethernet, each service can be discriminated based on several parameters
like quality of service.
Mapping different access technologies over Ethernet is achieved by standardized protocols
like circuit emulation and pseudowire.
