While the rollout of HSPA dramatically increases capacity available to end users to up to 14M, this increased bandwidth has serious backhaul repercussions – demanding an average increase in site connectivity by the equivalent of up to 7 E1/T1s. While existing backhaul networks can carry current high QoS traffic (like voice) and current "best effort" data traffic - the addition of this HSPA traffic promises to drastically increase network CapEx and OpEx.
HSPA traffic can be carried by lower cost networks, which carry best effort traffic only. These are usually either Ethernet/IP based network over xDSL, Metro Ethernet services or Ethernet microwave solutions.
DynaMate-based solutions from Celtro enable the separation of HSPA best effort traffic from the 3G R99 QoS traffic, sending HSPA over Fast Ethernet or Gigabit Ethernet to a more cost effective and separate best effort network.
