Market Trend: Cellular Operators move the
Tradtional RAN to IP
-
RAN, Why?


Backhaul of BSS/UTRAN is one of the major contributors to the
high cost of building out and running a mobile network.



Cellular operators have massive deployment of PDH/SDH traffic,
most reliable solution for GSM and R’99 UMTS backhaul.



PDH/SDH Mobile Backhaul solution does not seem flexible
enough to efficiently deliver statistical/bursty traffic.

Cellular operators would like to maximize revenues and
margins by converging mobile flows over a unified
Packet
Switched Network

infrastructure in order to reduce both
Capex

and
Opex

by using PW.

What is PW?



Pseudowire is a mechanism that emulates the essential attributes of a
telecommunications service over a packet
-
switched network


TDM leased line, ATM or ETH


It defines a way to packetize and encapsulate data and create a logical link
between two network entities


Pseudowire technology is an enabler for the migration scenarios, with circuit
and service emulation of legacy services over packet networks

Why emulate the ETH
-
Node over
PW?


ETH PW allows the ACE
-
3000 to backhaul ETH/IP traffic coming from
NodeBs

toward
the RNC over IP/MPLS networks


ETH PW on the ACE
-
3000 can be used together with TDM and ATM PW mechanisms in
cases where 2G BTS and 3G Node are collocated on the same site

Benefits
:


Unified ATM/TDM/ETH services over IP/MPLS


Automatic provisioning to all Cellular Backhaul services
