Hello, Saving Costs on 3G/UMTS Deployment
The business case for 3G still has to be made, however. Investments in 3G infrastructure will have to be undertaken in such a way as to minimize additional debt. 3G services, moreover, have to be rolled out without cannibalizing highly profitable SMS and voice applications. Incremental Deployment
of 3G Cutting Costs through
Traffic Aggregation RAD's new ACE-3000 line of products is aimed specifically at reducing cellular transport costs through traffic aggregation. Inverse multiplexing over ATM (IMA) capabilities enable the ACE-3000 products to collect traffic from several 3G sites and aggregate multiple circuits over n x E1/T1 IMA links or thicker STM-1/OC-3 pipes to the ATM access network. They also can deliver CES services over AAL1 to connect GSM equipment over ATM, allowing service providers to minimize costs by installing Node Bs alongside 2G base stations and use the same device for flexible aggregation and cost-effective transport towards the core cellular network (BSC/RNC). The devices offer the lowest price per port to and smallest size compared to existing solutions in the market. Adding to these advantages, ACE-3000 products provide a future-proof migration path, by providing Ethernet uplinks to be used over next generation Ethernet/IP/MPLS transport networks. This protects investment in equipment when the 3G network migrates to future cost-effective IP-based backhaul or when new revisions of the UMTS standards (i.e., 3GPP rev. 6) will be implemented. RAD Closes 2003 with Growth in Worldwide Sales RAD Data Communications has announced that its
global sales in 2003 reached $132 million, an increase of 3% over
2002, while orders were up 8% over 2002 figures, indicating increased
profitability in the year ahead. Full

RAD Equipment Connects Hundreds of Train Stations
in Integrated Railway Information System RAD's MAP and Last Mile solutions provide voice
and data connectivity among Romania Railways' 400 train stations. Complete Range of Products for Ethernet-over-SDH/SONET Solutions RAD's RIC-155 is the simplest and most economical way to transport Fast Ethernet protocol over SDH/SONET infrastructures. RIC-155 replaces expensive STM-1/OC-3 router interfaces or ATM devices, saving thousands of dollars. More details on RIC-155 The IMXi-4 intelligent inverse multiplexer transports
LAN or high speed data traffic across multiple, low cost TDM E1/T1
or SHDSL links by splitting the traffic onto multiple E1/T1 or SHDSL
links, accommodating transmissions of up to 8 Mbps over E1/T1 or
SHDSL lines. The IMXi-4 transfers Ethernet packets transparently,
enabling service providers to use their next generation equipment
in a TDM environment. The FCD-155 Ethernet-over-SDH/SONET access devices
also uses a type of inverse multiplexing -- virtual concatenation
-- to map Ethernet traffic into SDH/SONET virtual containers in
increments of n x 2 Mbps (VC-12) or n x 1.5 Mbps (VT1.5), up to
full wire-speed Fast Ethernet.

Sincerely, |
The
last three years have been a roller coaster ride for 3G mobile communications,
from the boom of optimism that led to fantastic auction prices paid
out for 3G licenses to the bust of recession, mountains of debt
and lack of investment capital for 3G infrastructure. The industry
is finally moving forward with 3G, characterized by the slow rollout
of 3G services, the growth of 3G applications and the increased
availability of 3G handsets. 
Cellular
backhaul - transporting traffic within the operator's network -
is one place where cellular operators can cut costs. Operators can
reduce line costs by aggregating traffic from several sites on to
the same link, thus enabling the operator to lease fewer lines to
deliver the traffic. Furthermore, implementing the same transport
link for the co-located 2G base station (BTS) TDM traffic and 3G
Node B ATM traffic also reduces costs. 
RAD
Data Communications' IPmux TDM over IP (TDMoIP®) gateway
has been selected by one of the largest institutions of higher education
in the United Kingdom, St. Helens College, which is based in the
north of England. The IPmux will provide high quality converged
voice and data services to the college's three main sites, whose
approximately 500 telephone extension handsets are used by between
13,000 and 20,000 students at any one time.
Carriers
today are faced with explosive growth of Ethernet-based traffic
on the one hand, and extensive deployment of SDH/SONET rings on
the other, which are engineered primarily to handle voice traffic.
RAD has developed a complete range of converters for cost-effective
delivery of Ethernet and Gigabit Ethernet services over the reliable,
widespread SDH/SONET network.
