A Handheld Test Instrument for Government and Public Safety Communications Systems

The only true method to measure coverage of the new U.S. government-mandated P25 Public Safety communications systems is to conduct Bit Error Rate (BER) analysis. Therefore, installers and maintainers of P25 systems need to use test instruments that can conduct BER measurements. Fortunately, Anritsu has introduced the S412D LMR Master®, the first handheld solution that can fully measure, demonstrate and document performance of a P25 system from the transmitter and antenna, to map BER performance throughout the promised coverage area.

A lightweight, easy-to-use battery-operated instrument, the LMR Master combines the functionality of a cable and antenna analyzer, spectrum analyzer, interference analyzer, power meter, P25 modulation analyzer, and P25 coverage mapping solution. It significantly reduces the number of tools field technicians and engineers must use, thereby saving time and money while ensuring communication system performance.

The S412D provides the full suite of measurements offered by Anritsu’s industry leading Site Master analyzers, plus P25 transmitter measurements and P25 coverage mapping. Covering the 25 MHz to 1.6 GHz frequency range, the S412D can conduct antenna, cable, transmission, and transmitter measurements, as well as interference analysis. In addition to BER, P25 transmitter measurements that can be made include constellation, EVM, and symbol deviation.

BER is the only true measure of P25 system coverage due to multipath and local interferers. Anritsu has designed the S412D to measure and log BER on the P25 1011 Hz test pattern along with GPS location and time. The measurement capability in such a compact handheld instrument significantly simplifies coverage drive testing. Fast and easy coverage mapping can be achieved with the S412D, as the handheld analyzer can internally store 8 hours of BER and RSSI testing.

The Anritsu S412D utilizes the field-proven design of the Site Master. Compact yet rugged, the S412D is specifically designed for field environments and can easily withstand the day-to-day punishment of field use. The analyzer is almost impervious to the bumps and bangs typically encountered by portable field-based equipment. The battery can be changed without tools in seconds, when necessary, to help extend measurement time in the field. The standard transmissive color display is viewable in direct sunlight and at wide viewing angles.
The LMR Master also utilizes Anritsu’s Master Software Tools. This software provides a simple and easy method to manage, archive, analyze, and print measurement reports; customize cable, antenna, and signal standards lists; and keep the LMR Master up to date with the latest instrument firmware. In addition, Master Software Tools can convert RSSI and BER measurements along with GPS location/time into a comma delimited ascii format for use with mapping software.

Larsen’s Portable Antenna’s

Nearly half the commercial communications radios sold today are portables. With the installed base increasing at an extraordinary rate, the demand for replacement antennas is growing fast. Unlike mobile and base antennas, portable radio antennas are subject to a variety of abuses leading to premature failure. Antennas are twisted off, sat on, slammed in the door and used to pull the radios out of their holsters! The result is an average need for replacement every four years.

In answer to the demand for portable antennas, Larsen offers a full line of Kulduckie® (KD) and SPOTS! antennas. Our fully molded design produces an ultra-tough antenna ready for severe handling and weather conditions.

Larsen KDs are recognized around the world as the ultimate in high-performance portable antennas. Each antenna is constructed of superior conductive materials and hand-tuned to the frequency specified by the customer. Each antenna is tuned to frequency using a mechanical radio body simulator to give the most accurate frequency response. As most portable antennas are ground plane dependent, it is important to specify the application the antennas will be used on to ensure accurate factory tuning.

Larsen SPOTS! antennas represent the leading edge in modern antenna technology. SPOTS! are built to the same high standards used in Larsen’s OEM antenna production. These antennas are the same design and construction as supplied to many of the top radio producers. For specific part numbers and applications, consult your expert at Talley.

The antenna measures 30 inches in length and provides 4 dBi gain on the 850 MHz band and 5 dBi gain on the 1900 MHz band. This heavy-duty antenna is designed for uniform coverage and excellent frequency response. The antennas are ground-plane independent and can be mounted either in-building or outside. The rugged radome will withstand harsh weather conditions.

For WiFi applications using 802.11a/b/g/n, the new ECO5-2400/5500 Omni-directional Antenna provides 5 dBi gain on both: 2400-2500 MHz and 5150-5925 MHz. The slim-line ECO Series antennas are encased in an extremely tough fiberglass radome measuring less than 11 inches tall and 1 inch in diameter at its widest point. The standard configuration terminates with an integrated N-female connector, but the antenna can also terminate with a direct connector, or a pigtail with a choice of connectors. Mobile options, with a mag-mount or trunk-lid mount, are also available.

Both the OD Series and the ECO Series antenna lines are weatherproof and durable enough for either indoor or outdoor use. These antennas are suitable for single site applications or as part of a network of antennas. With more antenna choices, network development is easy and economical.

Broadband Wireless System

Municipalities, public safety agencies, schools and hospitals are increasingly turning to broadband wireless systems to extend network boundaries, reduce ongoing operating expenses and add new applications. Here are some important things to look for when choosing a broadband wireless system.

Form Factor- Extending the network reach often implies putting IP based devices such as video cameras for surveillance outdoors where they are not sheltered from the elements. Because of this it is imperative to ensure that your broadband wireless system is rated to at least IP65 with regards to water and dust resistance. Additionally, it is important to feed the system with a standard, 802.3af, Power over Ethernet signal in order to leverage the ecosystem of PoE devices (switches, cameras, etc.).

Maximize Spectral Use- License Exempt spectrum is allocated in contiguous blocks. In order to ensure that you can always get a free channel it is important that your broadband wireless system is TDD based (uses only one channel) and that you can set the center frequency in as many places as possible. Look for systems with the smallest channel step size possible.

To support as many applications as possible, ensure your system has a dynamically adjustable uplink downlink ratio to ensure that you can use all the bandwidth in either direction (video surveillance is typically more than 75% uplink, internet traffic tends to be the opposite).

Operational Considerations- Your system should support obstructed Fresnel Zone propagation (sometimes called OLOS), in order to ensure that you make a link with the lowest possible tower height and the smallest antenna. OFDM systems for example can provide you with such capability.

Flexible Configurations- Different applications require different equipment configurations. Your system should be capable of supporting a variety of different throughputs to support users with varying bandwidth requirements. Deployment flexibility can also be achieved through the use of systems that allow configured channel bandwidth. User selectable 10, 20 and 40MHz channel bandwidth can provide added flexibility for you to optimize spectrum use, stay clear of interference, maximize throughput and achieve dense co-location needs. Additionally, systems that can support Point to Multipoint operation are preferable.

When choosing a broadband wireless system, the key features to look for is that it is OFDM based, can be fed by a standard power over ethernet feed, has adjustable TDD and can support flexible configurations.

Redline’s AN80-i

Redline’s 3.65 AN-80i is the first backhaul and premium access Ethernet product for the new licensed broadband wireless spectrum. It is available in point-to-point and point-to-multipoint mode. This will allow broadband wireless operators to take advantage of the special licensed status of the 3.65GHz band for backhaul of their networks.

The AN-80i is purposely built for backhaul and business-grade access, providing high throughput, low latency, security and reliability. It is designed to comply with the FCC Part 90 rules for the full 50MHz of the 3.65 GHz band.

It is a high capacity product that provides the same WIMAX feature set to ensure low latency and high throughput yet incorporates the same robust form factor and same software as Redline’s AN-80i. Where WiMAX is optimized for residential access, the AN-80i operating in 3.65 GHz is optimized for backhaul and business grade access.

Unlike 802.11 based systems, the core engine of the AN-80i is based on the IEEE 802.16 family of standards with proprietary extensions designed around achieving high throughput and low latency in order to optimize performance for backhaul and premium access applications. It is this core MAC/PHY engine that allows the AN-80i to achieve the best latency, highest throughput and greatest line of sight (LOS) and non line of sight (NLOS) range in the industry.

The 3.65 GHz AN80i supports 5, 7, 10, 14, 20 and 28 MHz channel sizes and up to 23 dBm output power (region specific). It is capable of sustaining very long links of greater than 50km.
