The increase in cellular traffic raises challenges for mobile operators. Past experience shows that cost-per-bit grows in direct proportion with the growth in capacity. No less troubling is the erosion in revenue per transported bit which will only worsen with new media-rich services. Decoupling cost and capacity becomes the major theme in the industry, driving the shift towards all-IP networks.
This paper describes some of the common myths - and basic facts - regarding mobile backhaul networks migration to IP. 1. Myth: “The migration to all-IP backhaul requires building and
maintaining two separate networks – one for TDM and another for pure IP”
Fact: There’s simply no business case that can justify building two parallel networks.
Although all-IP networks are the end-game for mobile backhaul, the migration phase will
take several years. During this time both TDM and IP equipment within will coexist within
the operator’s network.
The Native2 concept, also referred to as “offload” or “hybrid”, suggests a gradual
Ethernet phase-in with a later phase-out of TDM by delivering native Ethernet alongside
native TDM. Two different transport paths, TDM for voice, IP for data, will be maintained
during this time, taking advantage of a single platform that supports both native TDM
and native Ethernet. The beauty of the Native2 concept is that a single device can be
used not only throughout the entire migration process, but also later as a pure
IP/Ethernet solution.
The aim of IP migration for backhauling traffic is to reduce costs rather than increase
them. Hence, re-use of existing infrastructure is essential. Native2 from Ceragon, means
no future replacement of equipment is required, capping legacy investments and
protecting CAPEX for years to come.
