 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.

100/200/400 Series I Digital Microwave Radios
Model 100-I Specifications
Model 200-I Specifications
Model 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:

  1. 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.

  2. 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.

  3. 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:
  1. 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.

  2. 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.

  3. 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 highly reliable, easy-to-use, flexible communications paths for a variety of modern telecommunications and business applications.



1100/200/400 Series II Digital Microwave Radios
Model 100-II Specifications
Model 200-II Specifications
Model 400-II Specifications

The 100/200/400 Series ll Microwave Radios, which operate in the 2.4 GHz and 5.7 GHz ISM bands (industrial, scientific and medical) support up to 4T1/E1 data rates, and you can use them for wireless links with path lengths over 40 miles. All T1 radios use forward error correction (FEC), for short-term data errors caused by noise spikes, fades, or other extraneous problems. An on-board micro-controller controls the user interface and provides intelligent operation with liquid crystal display (LCD), numerous self-test features, alarm outputs, and its NMS complies SNMP.




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:

  1. Because these radios have a spreading effect on the data signal, unlicensed operation means little or no delay in building your data network. The T-1 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.

  2. Extremely reliable and robust, these radios can operate properly with extremely low input signals. The rated specification 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.

  3. 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 DSSS circuitry, these radios incorporate a number of high tech features that include the following benefits:

  1. Outdoor RF unit that operates in the 30 +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 wind loads they would place on the tower. The wide operating temperature permits continuous operation for the most demanding applications in some of the most hostile locations around the world.

  2. 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.

  3. 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.

Licensed Frequencies - FSK    QAM    Compact
Our high performance, spectrally efficient, digital microwave radios are designed for medium to long haul applications. These radios operate in the 2 GHz to 38GHz frequency bands and are available in a wide range of data rates. Typical applications include cellular infrastructure, cell site backhaul and backhaul voice traffic, campus internet working and private networks. Available in both protected and non protected configurations, these radios will carry up to a full E3+E1 or DS3. Protected systems provide fully redundant transmitter and receiver components.


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

WIN 95 SNMP Monitor and Configurator
You view important network tuning statistics with an easy-to-use Windows 95 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.
