FOR IMMEDIATE RELEASE
ElvaLink Announced Availability of Gigabit Ethernet Mm-wave
Links
ElvaLink demonstrated the New 1.25Gbps Full-Duplex Radio Link
Solon, OH,
USA - March 28, 2005 - ElvaLink LLC, an associated partner
with ELVA-1 and innovative supplier of millimeter wave
wireless network equipment, is announcing the availability of
a new PPC-1000 series of Gigabit Ethernet point-to-point
millimeter wave radio links.
The
Gigabit ElvaLink radio bridge was designed for a wide range of
applications such as mobile backhaul, business network, FSO
backup, IP network and emergency recovery network. The
operating frequencies cover 71-75 GHz, 81-86 GHz, and 92-95
GHz. These are FCC licensed bands recently released by the FCC
for commercial use in wireless point-to-point communications.

ElvaLink's
PPC-1000 is a full-duplex Gigabit point-to-point link
especially designed according to FCC requirements. It provides
interconnection between remote LAN segments at ultra high
speed and utilizes Gigabit Ethernet protocols, which is the
evolving standard for switches and routers available from a
variety of telecommunication equipment manufacturers. One
full-duplex Gigabit Ethernet link provides 1.25
gigabit-per-second connectivity that is the equivalent of
approximately 650 T1 lines or 1,000 DSL connections. The
PPC-1000 product has 1000 Base-SX connections at each end of
the wireless link and transparently establishes the link
outputs. The resulting connection can replace a fiber-optics
cable physically connected end-to-end. The wireless mm-wave
Gigabit link provides fiber equivalent performance,
reliability and security but with no high deployment cost
associated with outdoor fiber installations.
PPC-1000
links have remote management as well as parameter monitoring
capabilities. A twisted pair patch cable connected to any
RJ-45 socket within the LAN will allow remote SNMP management
and parameter control of a set of PPC-1000 links from a
central location.
The
Gigabit Ethernet point-to-point millimeter wave radio links
have been designed with compact parabolic Cassegrain antennas
of 30 and 60 cm diameters. The 60 cm antenna has a 0.4° beam
width and 50 dB antenna gain parameters, which are fully
compliant with FCC specification requirements for E-band
communication. Note, the FCC recently allowed the use of
smaller, less expensive antennas with a minimum antenna gain
of 43 dBi and a 1.2 degree half-power beamwidth available on
the PPC-1000 ElvaLink systems as well.
The
PPC-1000 operating distances vary from 1 to 4.5 miles or 1.5
to 7 km for varying weather conditions depending of the link
frequency and rain intensity. One can calculate the distance
versus rain attenuation using FCC Bulletin Number 70,
“Millimeter Wave Propagation: Spectrum Management Implications”
July, 1997. Namely, for example, in the so called B-zone of
the US rain map the relevant guaranteed PPC-1000 link
distances will be from 1.2 mile (2.0 km) for 99.995% weather
availability up to 6.5 km for 99.9% availability. Meanwhile,
the carrier-class 99.995% availability corresponds to 0.4-hour
outage per year caused by weather factors, and the
enterprise-class 99.9% availability means 8.8 hours outage per
year.
It has
been proven experimentally that in actual practice the
operating distance for a mm-wave link could be longer for the
same availability than the above mentioned theoretical
distance estimations. The explanation is that the distances
are generally calculated assuming that rain intensity is equal
along the entire distance. But rain cloud intensity varies
along the distance between the link antennas. For instance,
there might be heavy rain at one end of the link and it may
not be raining at all at the other end. This natural factor
improves overall link performance during actual rain
conditions and allows extending the operating distances while
keeping the same level of link availability.
“The first
PPC-1000 link has already been sold to an undisclosed
international telecom giant, and their representatives even
participated in PPC-1000 commissioning tests in Feb 2005,”
said Daniel Korneev, President of ElvaLink. “We are optimistic
and we expect a good response from the market to our new
PPC-1000 Gigabit Ethernet links. We appreciate the opportunity
to bring to thousands of US commercial customers online
fiber-like capacity using ElvaLink millimeter-wave wireless
links”.
