CIS Technology provides a new tool
PEPRO, Pioneer Energy Products, has developed an innovative convergent interstitial shield technology (CIS). This enclosure, called the GAUSSBUSTER protects sensitive solid-state electronics or digital micro-processor based equipment from lightning, electromagnetic fields, and radio frequencies.
In addition to lightning protection, CIS technology also minimizes the ability of radio frequency signals to penetrate the enclosure and cause fundamental signal overload or intermodulation with an average shielding effectiveness rating of 70 DB.
Tested by internationally recognized laboratories, Lightning Technologies and National Technical Systems Lab, PEPRO’s enclosure systems are designed to power industry standards. Results show that approximately a 50,000 volt 50,000 amp lightning strike directed onto the enclosure will result in less than .5 volts penetration to the inside of the enclosure.
The GAUSSBUSTER delivers the highest level of protection at a price far less than the total installation cost of conventional unprotected enclosures. Offered with a maintenance free exterior, the GAUSSBUSTER comes in a variety of sizes, which includes both, a walk-in model or a lightweight compact, low-profile model for small site restrictions and roof top applications.
Designed with an aluminum welded unibody construction and an insulated, paneled interior, the units are factory assembled and tested prior to shipment.
The GAUSSBUSTER is available with a variety of optional features such as automatic or manual transfer switches, hydrogen detectors, air conditioners, or hi-temp alarm/shutdown switches. PEPRO’S patented technology, the GAUSSBUSTER, is the only commercially available shielded aluminum enclosure that provides this high level of security for computers, wireless technology, and other sensitive electronic equipment used in the oil/gas industry, electric utility industry, or public safety radio communications.

Quasi-Sync offers simulcast solution
The benefits of simulcast systems are well documented and time tested. However, the drawbacks of simulcast may not be as evident.
Traditionally, simulcast radio systems provide wide area radio coverage by using a number of transmitter sites all transmitting on the exact same frequency. This approach places great demands on mobile radio system components and on the linkage between sites. In some areas, reception can be dominated by a single transmitter, while in others a user may receive signals from two or more transmitters simultaneously. The result oftentimes is signal cancellation.
However, there is an alternative to traditional simulcast that promises to solve this and other issues.
The Tait Quasi-Sync system differs from others in that it uses a closed loop equalization system. That is, the signal that is being fed to each of the transmitter sites goes through an equalization process that compensates not only for differences in the transmission line, but also for variances in the transmitter equipment. This is done through the use of an off-air monitor receiver that feeds back the received signal into an equalization process. This has the advantage of allowing the Tait Quasi-Sync system to not only use different transmission mediums for each inter-site connection, but also different makes and models of transmitter equipment.
The Tait Quasi-Sync system uses high stability oscillators to maintain a very stable transmitter frequency. In addition, digital signal processing (DSP) based Line Equalizer Modules, routing audio to each transmitter, analyze the characteristics of a neighboring transmitter and adapt their own signals to match.
Superior Coverage and Enhanced Reception are two other key features that make Quasi-Sync unique. Wide area coverage is achieved with a single channel, eliminating the need for multiple licenses and releasing frequency spectrum.

Alvarion system a Breeze
Alvarion Inc. announced the commercial availability of BreezeACCESS, a traffic management system that offers public safety officials, city IS managers and service providers the ability to securely carry and manage 911 and other emergency messages in their wireless fixed and mobile networks. Comprising a complete set of traffic management tools contained in a stand-alone system extension to the BreezeACCESS product line, the TM solution enables traffic managers to accurately control the amount of bandwidth allocated to each user and the priority of each message in the link.
Building on the field-proven quality of service (QoS) capabilities of the BreezeACCESS product family, the TM system is typically deployed at the network operations center to establish up to 10 levels of overall traffic priority and to set the bandwidth throughput of each subscriber in the network as defined by minimum, maximum, guaranteed and committed burst rates. While in operation, the TM system matches each traffic session with a user and then forwards data packets according to the parameters set by the administrator for that user. As a result, bi-directional wireless network traffic for every user and application can be monitored, managed and shaped.
Because it increases network security and ensures data delivery, BreezeACCESS TM now allows carriers to sell independent and protected bandwidth to municipal organizations for public safety applications. In turn, homeland security agencies can use TM’s accounting services module, which aids the measurement of customer resource usage, to sell bandwidth to the municipality, generating extra revenue from an underused radio network.
Traffic supervision is accomplished through a user-friendly Web interface, which enables IS managers to set policies that regulate MAC address or IP address authorization and even network access, thereby allowing them to turn a specific user’s access to the network on or off.
Optimized for various customer needs and operating environments, the TM is available in four versions. Ranging from the TM-502 which supports 256 communication links of up to 2Mbps each, 12,000 simultaneous users, and 2,048 QoS policies, to the TM-1100 which supports 1,024 communication links of up to 100 Mbps each, 96,000 simultaneous users, and 4,096 QoS policies. All TM systems feature three 10/100BaseT ports, including shaping, monitoring and hardware bypass features.
