About Microwave
Radios With modern microwave
technology, you can connect two or more facilities quickly and
easily. Because you own your own network, we can design the system
to meet your specific requirements. Such competitive technologies as
fiber, LEC, T-1s, and xDSL all require third party service for
transmission, so the user is subject to the availability and quality
of the service provider. In contrast, the microwave user can
establish connectivity quickly and need not rely on the political
"right of way" access permission associated with fiber or LEC T-1
connectivity. With modern microwave technology, you also benefit
from the relatively low fixed costs associated with constructing the
link or links and the rarity of recurring service costs.
The Market The traditional markets for microwave
are long distance telephony carriers, private network operations,
utilities, and the military. More recently, cellular operations,
CLECs, and ISPs have become strong users of microwave.
Cellular, PCS, and GSM Cellular carriers often
face aggressive schedules to provide expanded service for their
customers and continue generating immediate return on investment. In
order to expand their networks, cellular carriers must connect their
cell sites to switching stations. To make these connections quickly
and easily, carriers often choose microwave because it is reliable
and can be rapidly deployed. We can often commission such a system
in one day.
Local Distribution Many businesses
use microwave technology in their private networks because it offers
the fastest digital communications installation. Microwave systems
are a low cost, high security alternative to many traditional
communications system options.
Control and
Monitoring Public transport organization, such as railroads,
and other public utilities are major users of microwave. These
companies use microwaves to carry control and monitoring information
to and from power substations, pumping stations, and switching
stations.
Long Distance Carrier Connection
Long Distance Carrier Connection A significant portion of the cost
of a long distance telephone call is the cost associated with the
connection to and from the long distance carrier. Microwave radios
can connect the end user to the long distance carrier and
significantly reduce cost. In areas where long distance service is
available but local lines are not, microwave can provide the "last
mile" connection. See our section on wireless local loops.
Disaster Recovery Natural disaster can wreak
havoc on a telephone network and its supporting infrastructure.
Utilities often use microwave systems to restore communications
while replacing damaged infrastructure.

400-I Specifications
The 100, 200 & 400 Series I wireless terminals provide a
highly reliable, full-duplex data link between points located as
many as 40 miles apart. Available for operation in the unlicensed
2.4 GHz and 5.7 GHz ISM bands (industrial, scientific and medical),
the model 1050 and model 6050 both support data rates from 56Kb/s up
to 4T1/E1 data rates. The three different available user data
interfaces are V.35, DSX-1, and G.703. The data rate and clock
source are both front panel configurable. All radios use a FEC codec
for enhanced data reliability against errors caused by noise spikes,
fades, or other extraneous problems. An |
|
on-board micro controller
controls the user interface and provides intelligent operation and
numerous self-test features. Some of the self-diagnostic tools
include such built in test equipment (BITE) functions as BER, near
and far-end Loopback functions, and alarm outputs (contact
closures). The personnel in a central monitoring facility can use
the network management system (NMS) to manage large networks of
these products remotely, and the NMS is simple network management
protocol (SNMP) compliant.
Each link has at least two end
points, You can, however, develop more complicated networks. As a
minimum, each facility has the following equipment: indoor modem
unit that is installed near the users' data equipment, an outdoor RF
unit, and an antenna that is typically 2-8 feet in diameter. With
this flexible equipment configuration, you can separate the antenna
and the data equipment without any degradation of link performance,
and a single coaxial cable provides all the necessary interface
signals. Moreover, the various antenna sizes available permit link
operation over a wide range of distances. An optional antenna
alignment unit (AAU) that provides various indicators for correct
antenna pointing is available for installers. The AAU furnishes a DC
voltage proportional to the received signal, which can be read by a
meter. An audio tone with a frequency proportional to the received
strength is provides hands-free antenna alignment. The Model 400, a
4xT1 or E1 solution for voice and data applications between two
locations as far apart as 30 miles or 50 kilometers, delivers very
low BER links that are highly immune to interference. Using spread
spectrum microwave transmission, two Model 400s with line-of-sight
access create a robust wireless link. These links are ideal for
public and private networks, frame relay applications, and last-mile
feeders into fiber-optic and satellite networks. Applications
include wireless local loop (WLL), wide area networking (WAN),
metropolitan area networking (MAN, and cell-site
interconnections.
These radios incorporate direct sequence
spread spectrum (DSSS) technology. Originally developed by the US
military for its coding capabilities, DSSS radios are now
commercially available and offer the following unique
benefits:
- Because these radios have a spreading effect on the data
signal, unlicensed operation means little or no delay in building
your data network. The data stream is spread over a bandwidth ten
times normal; however; this spreading effect reduces the energy
density of the signal. The new signal resembles noise, and the
code used for spreading is usually referred to as a pseudo noise
code (PN code). This lack of energy density is quite different
than most other forms of radio communication and is a major reason
these radios can operate without licenses. Essentially, the energy
of the signal is so spread out over its larger bandwidth that it
contributes very little to background noise and can usually be
operated in the same geographic region with other similar radios
without creating interference. The level of interference is one of
the main criteria used by the regulatory government agencies to
determine rules for new services or operations.
- Extremely reliable and robust, these radios can operate
properly with extremely low input signals. The rated specification
is operation down to - 91dBm input level or a receiver level of
one-trillionth of a watt for proper operation. The spread factor
reduces the effects of noise and other interfering signals
permitting operation in extremely hostile environments.
- These radios provide data encryption. The PN code used for
spreading and de-spreading the signal also breaks the data up into
tiny pieces called chips. The spreading process encodes the
transmitted signal, and the code is virtually unbreakable without
knowledge of the PN code. Besides the tremendous benefits offered
because of the inherent DSSS circuitry, these radios incorporate a
number of high tech features that also have tremendous user
benefits including:
- Outdoor RF unit that operates in the -40 to +55 degrees
Celsius temperature range is housed in a rugged, weatherproof
NEMA-4 enclosure. The outdoor unit mounts directly next to the
antenna and eliminates costly waveguide runs and the associated
pressurization equipment. In addition, the wind loads associated
with waveguide are eliminated because inexpensive, small
cross-section coaxial cable is used to route the signals from
the indoor modem to the outdoor RF unit. The wide operating
temperature permits continuous operation for the most demanding
applications in some of the most hostile locations around the
world.
- User friendly design incorporates micro-controller
technology with an easy-to-use LCD interface with menus that you
can use to configure your radios. The self test and loopback
features facilitate identification of failed network components.
In addition the optional network management system uses code
that is SMNP compliant. Alarms at the rear of the indoor chassis
can drive other circuits in the event of a system
failure.
- With the optional NMS, you can monitor, configure, and
control the system from a remote office. The following are key
features of the NMS:
- PC-based
- Graphical point and click
- SNMP gateway
- Alarm reporting
- Remote control
- Configuration management
- Operates over dial telephone lines or in-band on the RF
channel
The 1050/6050/400 series of wireless terminals are

variety of modern telecommunications and business
applications.

The 4T1 or 4E1 model, which is
backward compatible with existing radios, is an easy and inexpensive
way to migrate from a single T1 (or E1) circuit to four connections.
Along any existing path, you need change only the upgrade because
the other parts of the link are fully compatible with these new,
higher speed models. New customers can also take advantage of this
improved capability. They can order the four-channel versions from
the start or, if they prefer, start with a single T-1 circuit and
upgrade as necessary. Either way, these radios offer the finest
technology and an excellent way to take control of your need for
high-speed data circuits without incurring a high monthly telco
bill. The Series II radios incorporate direct sequence spread
spectrum (DSSS) technology. Originally developed by the US military
for its coding capabilities, DSSS radios are now commercially
available and offer the following unique benefits:
- Because these radios have a spreading effect on the data

is operation down to - 90dBm input level or a receiver level of
one-trillionth of a watt for proper operation. The spread factor
reduces the effects of noise and other interfering signals
permitting operation in extremely hostile environments. For radios
operating in the T-1 mode, the advanced FEC circuitry provides
additional data security because the receivers circuits can
correct random data errors before the data enters the far-end
network.
- These radios provide data encryption. The PN code used for
spreading and de-spreading the signal also breaks the data up into
tiny pieces called chips. The spreading process encodes the

other circuits in the event of a system failure.
- The radios have built-in performance monitoring. By monitoring
some of the various performance parameters, a maintenance engineer
or technician can see a failure occurring before it becomes
catastrophic. For example, the T-1 radios have a feature with
which operators can monitor the Bit Error Rate (BER) of the
circuitry before the FEC circuit. This parameter, called pre-FEC
BER, can be very useful because it yields a figure of merit
concerning link operation. Under normal operation, this value is
very low, often zero. If you keep a simple log of this parameter,
any rise in the historic value may indicate that the link is
beginning to fail. Other parameters can help determine the cause
of the failure, so that you can repair or replace the failing
portion. When properly used, these features can by provide the
necessary maintenance information and minimize downtime.

Family of Licensed Microwave
Radios We use a custom application specific integrated
circuit (ASIC) that has a consistently repeatable design and uses
high spectral efficiency modulation schemes. The ASIC contributes to
the overall robustness of the communication link. Systems that use
separate digital interface units (DIUs) and indoor or outdoor RFUs
are the ultimate in system flexibility and the efficient use of
microwave power because, in most cases, short, low loss jumper
cables replace long, expensive waveguide installations. This feature
eliminates the waveguide purchase cost and its associated
connectors, mounting hardware, pressurization equipment, and
installation. In addition, it eliminates tower loading because you
can install it on towers that might otherwise be unusable because of
their capacity. Many existing towers have little or no additional
headroom for tower and wind loading, and the upgrades to increase
the capacity are very time consuming and expensive.
Other
features include triple error correction, wide dynamic range
receivers modular design with built-in diagnostic and test
capabilities, and digital orderwire and service channel options. In
addition, you can order an integral NMS that complies with SNMP or
the commonly used TBOS so that you can continuously monitor critical
system performance parameters from remote locations. Regardless of
your licensed radio application, our family of licensed radios has a
product designed for your requirements.

Typical Product
Applications
Bridge and IP/IPX Router
Functionality SPEEDLAN 10
comes from the factory as a transparent, MAC layer, self learning
wireless bridge with customer configurable IP and IPX routing
capability that will connect two or more Ethernet LANS. The bridge
can pass all Ethernet-like protocols including IP, IPX, and
Appletalk.
3 in 1 Bridge and
Router Four ports are
available as ethernet, 2 Mbps or 4 Mbps wireless at 2.4 GHz or 900
MHz, and 10 Mbps at 2.4 GHz. In a multi-point wireless network,
SPEEDLAN uses one or more wireless ports with omni directional 360
degree antennas or long range directional antennas. Three different
frequency sets may segment as many as three wireless networks for
maximum throughput and availability. Each wireless segment can
accommodate multiple connections to remote locations. This ability
to operate three different wireless segments from the same chassis
reduces cost and increases configurability and usefulness of the
system for a wide range of applications.
Repeater
Functionality If you use
two radios in a single chassis, you can create a 2 or 10 Mbps
repeater and use it to extend distance or obtain line of sight.
Dynamic Bandwidth Allocation
Wave wireless changes the
normal random timing of wireless communication to a time division
polling protocol and significantly improves multi-point
communications. Multi-point wireless network performance usually
degrades because multiple satellite locations compete for the time
of a single radio at a central location. You can configure SPEEDLAN
products to eliminate these performance problems associated with
retransmissions and acknowledgments

application. Network managers see and manage wireless connections
remotely with a single graphical interface. They can view statistics
for wireless packets transmitted and received from each location and
the ethernet interface to the network. Windows 95 tools include
point-to-point and multi-point antenna alignment utilities, complete
remote configuration, management, and reboot capability. They can
also monitor equipment temperature and other metrics.
Ease of Support and
Management You can
administer SNMP wireless and wired link management from any ethernet
network or remotely from the Internet. You can upgrade software and
service the system from the Internet or through a SLIP "out of band"
management port and external modem. SNMP MIB II, Bridge MIB,
Ethernet interface MIB, and proprietary MIBs are included for the
bridge and router.They include RF signal level, quality, and noise
level.
