ith data rates up to
72Mbps, the Solectek
SkyWay 5000 delivers more data
capacity per sector than ever
before, extending 5.8 GHz range.
Users can now download large
data files, high-resolution
images, video clips, and MP3
files within a matter of seconds.
Even streaming multimedia can
now be delivered seamlessly.
The introduction of
Orthogonal Frequency Division
Multiplexing (OFDM) tech-
nology brings increased spectral
frequency and higher data
rates while providing multiple,
nonoverlapping channels.
Many users will find that OFDM
is capable of performing near
or non-line-of-sight (NLOS)
links. OFDM is also much
more immune to multipath
problems and resistant to poten-
tial interference.
The SkyWay 5000 Series is
fully integrated: digital baseband,
radio and antenna are all com-
bined into a single, weatherized
outdoor chassis, complete with
Power over Ethernet (PoE)
support. This product can be
installed at any convenient
outdoor location without worry-
ing about cabling difficulties.
Inexpensive Ethernet CAT5
(up to 300 feet) is all that is
required for connecting your
indoor network switch. Full-
function bridge/router software
and extensive network protocol
and network management
support are included. Visit
TESSCO.com or call 800-472-7373

Simplifying BOA Installations
uilt-in test equipment
(BITE) has long been an
integral part of many electronic
systems and CSI has now intro-
duced this concept into in-build-
ing systems.
Proper installation of an in-
building amplifier requires that the
installer bring to the site additional
equipment such as a spectrum
analyzer, power meter, or laptop
computer, along with the cables
necessary to connect them. The
new LCD two-line by 16-character
alphanumeric readout display and
navigation pushbuttons on the
models 510, 510-75 and 610 pro-
vide many key system benefits.
Now, by using this simple, intu-
itive interface, the installation
technician can observe uplink and
downlink power and AGC activity,
reducing the need for additional
equipment. Amplifier gain is set
by simply navigating through the
menus and directly setting the
gain desired—no more error-prone
calculation of attenuation values.
System troubleshooting is
also greatly enhanced by this
capability. Power and AGC levels
can be compared to identify sys-
tem changes. Accurate measure-
ments can even be obtained
from nontechnical staff at the
end-user’s site, minimizing
unnecessary site visits. To help
the installer ensure a successful
installation, these models also
incorporate an oscillation detec-
tion and suppression feature.

software for complete network
power management and con-
trol. The SmartPro1050SLT
and 1500SLT models feature
advanced automatic voltage
regulation, plus up to 18 min-
utes of battery runtime at
half-load. The SmartPro 750XL
offers expandable runtime
capability with additional
external battery packs.

It’s still a land grab for service providers—
whether you are a traditional wired ISP or a
WISP. The faster and cheaper you can build
out your network, the more business you
can go after. And nothing lets service
providers do this better than theTsunami
MP.11a from Proxim. Capable of trans-
mitting greater than 20 Mbps or distances
up to 11 miles away, the Tsunami MP.11a
lets you scale quickly and offer economical
residential solutions that can compete with
DSL and cable. The solution is self-installable
and provides remote management
capabilities to keep your deployment and
maintenance costs at a minimum. It also
features a Radius client that lets you offer
multiple service options to business and
residential customers. Tsunami is so cost-
effective that many businesses are already
using it to replace leased lines between
buildings, network whole campuses, and
even deploy outdoor surveillance systems.

Tsunami™ MP.11a offers service providers the most economical point-to-multipoint solution on the market.
multi-output (MIMO) radio systems
are able to asses the real time chan-
nel conditions and adjust how data
is sent to multiple transmit anten-
nas and how best to extract symbols
from multiple receive antennas.
Progress in this area is rapid, but the
complexity of multi radio designs
prevents such an approach from
being cost-effective today.
It has been demonstrated that
a high-power OFDM radio is able
to open many more potential
client sites as compared to older
technology with little to no cost
penalty. The wideband OFDM
engine provides all of the benefits
described previously, including
tolerance of multipath fades, elim-
ination of delay spread and
Doppler effects. A 400 mW RF
stage creates the link gain to work
through many instances of shad-
owing effects and absorption
through obstructions.

power OFDM radios, please see the
