RAD introduces aggregation solutions for 3G networks
January 19, 2004
RAD's new ACE-3200 and ACE-3400 aggregation devices are designed to accommodate
the rapid expansion in cellular backhaul traffic that will inevitably
result from the widespread deployment of 3G services.
"Aggregation of E1/T1 lines is the ideal solution to simultaneously ensure
the most economical allocation of backhauling resources and the delivery
of dependable multiple 3G services to the customer," explains Gabriel
Junowicz, Senior Business Development Manager for Cellular and Wireless
Networks at RAD Data Communications.
Co-location and Aggregation Lower CapEx and OpEx
Given the initial cost of UMTS services, not all mobile subscribers will
be able or willing to upgrade immediately to 3G. "For that reason GSM
will not be replaced overnight in one fell swoop, but, instead, will continue
to co-exist side-by-side with 3G networks for many years to come," Junowicz
predicts. "Due to the lengthy transitional period between 2G and 3G, it
will not be uncommon for 3G/Node Bs to be co-located at the same site
along with 2G/BTS facilities," he notes. "A single aggregator for both
generations of technologies will not only yield significant savings on
CapEx and OpEx, but also will furnish cellular service providers with
the flexibility and dexterity to move between CES and UNI/IMA."
The ACE-3200 and ACE-3400 aggregation devices are optimised to provide
CES services over AAL1 in order to connect GSM equipment, as well as IMA
to connect UMTS, both over ATM. This solution will allow operators to
minimise costs by establishing Node Bs alongside 2G base stations and
using the same transport network for all cellular services. The ACE-3X00
products will be able to aggregate traffic from several sites and transport
them onto a single ATM link.
Flexible Devices
The ports on the ACE-3200 and ACE-3400 will be software-configurable
as TDM or ATM (UNI or IMA), enabling operators to purchase one type of
unit and adjust it as required for the co-existent environment. This feature
frees both operator and carrier from having to anticipate in advance the
number of ports required for each service and eliminates the need to maintain
an inventory of alternative ports in order to respond to changes in demand
for those services.
Future-Proof Investment The ACE-3X00 products, moreover, can be ordered
with either an ATM or Ethernet uplink. This protects the carrier's investment
and a smooth 3G and even 4G migration path to next generation backhauling
over IP/MPLS networks.
The ACE-3200 aggregates E1s at BTS/Node B locations, dramatically reducing
the number of E1 lines that the operator will need for backhaul. It can
also be deployed by carriers at their points of presence (POPs) to economise
the simultaneous provisioning of backhauling services to different cellular
operators. The product can be ordered with either 8 or 16 ports.
The ACE-3400 will be available later this year. A modular device, it
can be ordered to accommodate either 32 or 63 E1 or 42 or 84 T1 ports
and, is specifically designed for deployment at the carrier POP or the
mobile RNC site. The product's cards are hot swappable so as to provide
service continuity.
