PARIS, Nov. 16, 2015 /PRNewswire/ -- Alcatel-Lucent
(Euronext Paris and NYSE: ALU) is to introduce a radio interface
for distributed antenna systems (DAS) to allow mobile operators to
improve signal performance while reducing power consumption, space
and operational costs by as much as 90 percent when connecting
subscribers at large public venues, such as shopping malls, hotels
and office blocks.
Alcatel-Lucent has launched the Distributed Antenna System Radio
Frequency Module, a wideband low-power LTE interface card which
removes the need for bulky radio technology in a public
installation. Working together with Alcatel-Lucent's LTE radio
access portfolio, the DAS RFM connects to Alcatel-Lucent's 9926
digital baseband unit, working directly with the analog DAS through
RF signals that consume just one-eighth of the power and heat
dissipation of an average remote radio head, reducing space
requirements and optimizing costs.
The launch of Alcatel-Lucent's DAS RFM comes at a time of rising
use of distributed antenna systems, particularly by mobile
providers in the United States and
China, as demand grows for
high-speed, ultra-broadband access in busy public locations. In
order to connect to a DAS today, service providers must deploy
remote radio heads alongside duplexers and attenuators to reduce
output power, as well as cooling equipment in areas where there is
often limited space.
Bell Labs has completed a study
on the cost savings delivered by the new DAS RFM, compared to a
traditional RRH and associated equipment. The study shows that by
reducing equipment and power requirements, service providers can
realise:
- Up to 30 percent cost savings in terms of the wireless and DAS
equipment required
- Up to 81 percent cost savings in terms of power and
cooling
- Up to 91 percent cost savings in terms of construction
- Up to 78 percent cost savings in terms of energy
- Up to 91 percent cost savings in terms of space
By connecting the DAS RFM into Alcatel-Lucent's distributed
radio access network architecture, operators can also take
advantage of scalable technology. The 9926 digital baseband unit,
connecting into a number of distributed radios, can divert capacity
where needed when there are spikes in traffic, redistributing
capacity to other radios when no longer required.
Commenting on the launch, Nick
Marshall, Research Director of ABI Research said:
"Alcatel-Lucent's new DAS RFM solves a major problem for operators
and building owners alike. In the most densely populated areas
where DAS technology is commonly deployed, space is a premium and
lease costs are high. Alcatel-Lucent's product will reduce the
amount of equipment needed and with neutral host capabilities it
can connect to any DAS."
Key Facts:
- By providing a simple RF signal, the Alcatel-Lucent DAS RFM
maintains the host neutrality of a DAS system, allowing multiple
operators to share a DAS system and recognize associated
cost-savings.
- Alcatel-Lucent's compact (half rack unit size) low-power DAS
RFM, significantly reduces space, power and cooling requirements
when connecting to a Distributed Antenna System. It operates in
both indoor and outdoor racks. Up to 40 radio sectors with the
associated baseband processing, can be fitted into a standard 19
inch indoor cabinet. The Alcatel-Lucent DAS RFM is offered in two
wideband hardware versions, one for low band and one for high band
radios. Each radio covers between 6 and 10 bands. Based on the
latest Alcatel-Lucent RF platform it leverages common hardware and
software and can quickly be adapted to various market frequency
demands using pluggable cards.
- Configurable parameters enable better alignment across the
system on the uplink and downlink power used at the DAS remote unit
to improve radio performance. First live tests have shown up to
10dB improvement in uplink noise which equates to greater cell
coverage or data speeds and allows the radio to serve more
end-users.
- Filter cards will be made generally available by end of
December 2015 in selected frequency
bands.
Glenn Booth, Senior
Vice President and General Manger of Alcatel-Lucent's LTE Business
Unit said: "Alcatel-Lucent has been working closely with
operators on how to improve LTE deployment in dense urban
environments by leveraging their DAS infrastructure. This product
was developed on the latest leading edge RF Platform that operators
use for their Macro today allowing them full benefit and feature
parity with their Macro sites. It is designed for use with any
vendors' analog DAS."
