Multi-application wireless antennas
Pulse Engineering introduced the W1000 series of omni-directional antennas designed for original equipment manufacturers and which are 802.11a/b/g/n, Bluetooth and ZigBee compatible. They also are compatible with other devices operating on the ISM band and are RoHS-compliant, the company said. The dipole antennas provide 360 coverage to improve point-to-multipoint transmission and reception between devices on WLANs. Six models are available, with frequency ranges of 2.4 GHz to 2.5 GHz and 5.15 GHz to 5.85 GHz, with impedance of 50 ohms, resonance of ¼ wavelength and vertical polarization.

Features added to system controller
Zetron has added an interface to its Project 25-compatible Series 4000 communications control system that lets users connect to Nextel’s nationwide Direct Connect push-to-talk network. In addition, the company has added an application that lets users create a remote console position that connects to the main switch over an IP network. The information depicted on the remote console screen is the same as what is seen by operators in the main communications center, according to the company.

Base station/repeater
Tait Radio Communications unveiled the TB7100 base station/repeater, which provides continuous duty operation at 25 W, 40 W (UHF) or 50 W (VHF) power output. It is designed for use with an external DC power supply and comes in a 19-inch 1U rack bin, which can be wall-mounted. With an optional internal duplexer, the TB7100 is capable of full duplex operation for a voice or data channel and offers data rates up to 19.2 kb/s, the company said.

UHF/VHF portables
Vertex Standard introduced the VX-920 Series of UHF (400 MHz to 470 MHz and 450 MHz to 512 MHz) and VHF (134 MHz to 174 MHz) portable radios. The radios offer programmable channel widths of 12.5 kHz, 20 kHz and 25 kHz, a 700 mW audio output, 48 or 512 channel capacity, a sub-receiver for cross-band operation, a submersible external microphone and power output of 5 W. The radios also offer several scanning options, and are rated IP55 (water projected by jets in any direction) and IP57 (submersible to a depth of 3 feet for 30 minutes) for dust and water intrusion, the company said.

4.9 GHz/Wi-Fi mesh network
Proxim Wireless Corp. announced a wireless municipal mesh network solution that operates in the 2.4 GHz and 4.9 GHz bands and offers broadband connectivity to municipalities where it is cost-prohibitive to install network wireless edge access devices. According to the company, the key component is a dual-radio node that offers four built-in antennas that offer both horizontal and vertical polarizations, which increases range in both the 2.4 GHz and 4.9 GHz bands. Three channel sizes are available — 5 MHz, 10 MHz, and 20 MHz — which provides greater flexibility to municipalities, particularly those whose footprint includes both urban and rural areas, the company said.

RFID reader wins Gen 2 certification
Symbol Technologies announced that EPCglobal has given Symbol’s XR400 radio frequency identification reader Generation 2 certification. The reader provides dense reader mode performance, which reduces interference between the XR400 and other readers operating in close proximity, a requirement for Gen 2 certification, according to Symbol. Baltimore-based MET Laboratories conducted the tests using rules established by EPCglobal for its hardware certification program. EPCglobal is a standards organization consisting of manufacturers, technology solutions providers and retailers.

Next-generation RoIP software
Catalyst Communications Technologies introduced Version 4.42 of its software that adds capabilities designed to let users better control and manage their RoIP dispatch and interoperability systems. The new capabilities include: the ability to link up to eight different radio systems regardless of manufacturer or frequency; the ability to transmit pre-recorded .WAV files over the air; and the ability to “cross mute” audio from a neighboring remote client, which reduces feedback into the neighboring remote client’s microphone during a transmission, the company said. Another new application lets dispatchers “tag” calls with lines of text, which is useful when trying to retrieve calls from an archive that includes thousands of calls. This feature, along with automatic time stamping of calls, provides a “simple electronic event records system,” the company said.

2.7 GHz service monitor
Aeroflex unveiled a new service monitor that extends the operating range to 2.7 GHz for analog and digital RF signals. Based on the IFR 3901 1 GHz radio test set, the IFR 3902 not only extends the operating range but also includes full analog duplex test capabilities as a standard feature. The IFR 3901 also can provide this functionality via an upgrade to firmware release 1.1. Both the IFR 3902 and the IFR 3901 support an optional site-monitoring application that analyzes the system’s noise floor and the effective receiver sensitivity. This monitoring option also lets engineers view interference issues with time- and date-stamped data without having to be on site.

Universal interface card
Daniels Electronics has announced the commercial availability of its Universal Interface Card (UIC), which can be integrated with Twisted Pair Solutions’ WAVE application suite to enable digital integration between all forms of land mobile radios, as well as personal computers, personal digital assistants, telephones and mobile phones. The UIC can be added at the base station to provide an Ethernet port into an IP network that allows communications between disparate radio systems, greatly enhancing interoperability possibilities between public-safety entities on different legacy networks.

Vehicle security and tracking application
Secured Digital Applications announced an integrated vehicle tracking and security application that lets fleet owners monitor vehicle use in real time. The application uses a smart card reader that identifies the driver and — by accessing a central server via wireless technology — obtains authorization for the vehicle to operate. It then monitors the vehicle for location or accidents using GPS technology and lets fleet owners establish geographic boundaries for vehicle operation. The device also will notify the fleet operator when a vehicle is being towed, the company said.
