Allgon Mobile
Stockholm, Sweden-based Allgon Mobile Communications AB introduced a dual-band antenna called “Twin,” which can be mounted on a car window. The antenna can receive and transmit Global System for Mobile communications-based digital signals at 1800 MHz and 900 MHz frequencies. Holes don’t have to be drilled in the roof of the car to install the antenna because the antenna whips are enclosed in a plastic strip that adheres to a glass surface, said Allgon. The antenna assembly includes an outer module, which is attached to the outside of the glass and sends and receives signals between the antenna whip and the inner module; and the inner module, which is attached to the inside of the glass opposite the outer module. A wire runs inside the car from the inner module to the adapter for a mobile phone. Twin is scheduled to be available this summer, and Allgon plans to introduce a glass-mount antenna for the North American dual-band standard using the 800 MHz and 1900 MHz frequencies this fall.

P-Com
A new generation of point-to-point radios introduced by P-Com Inc. uses new technology to broaden the application range of its Tel-Link series, said the company. The new radios are designed to be compatible with the Tel-Link series and other recent additions to P-Com’s product line, such as the spread-spectrum and point-to-multipoint radios, to provide the best network solutions for different customer requirements. The new generation radio design covers the market requirements of the medium- and high-capacity rates up to 16T1/16E1 and DS3. Reduced capacities of 4T1/4E1 down to a 1T1/1E1 rate also are available as simplified plug-in versions of the higher capacity. A new cost-effective version at T1/E1 rates or lower will be made available as part of the new microwave and millimeter wave generation. The first available radio will operate at 38 GHz, followed by the lower-frequency versions down to 7 GHz. (408) 866-3666.
JBRO Batteries
An 18-month warranty is included with both of JBRO Batteries Inc.’s new nickel metal hydride land mobile rechargeable batteries, announced the company. The JB-4013 is a high-capacity NiMH battery rated at 7.5 volts and 2100 mAh. JBRO said its new battery will replace Motorola Inc.’s WPNN4013, which fits the MT2000, HT1000 and MTX8000 radios. The JB-4595 NMH is rated at 7.5 volts and 2200 mAh. It is the NiMH equivalent of the JB-4595 NiCd battery that fits the Saber MX1000 radio. (630) 964-9358.
Northwood Geoscience
Canadian geographic information services mapping solutions innovator Northwood Geoscience Ltd. announced it now is shipping deciBel Planner, a radio-frequency propagation mapping solution for wireless telecommunications that is integrated with the MapInfo Professional desktop mapping software. The software is used by engineers to model RF propagation results to field tests to select transmission tower locations. Bell Mobility, a Canadian service provider, already is using deciBel Planner and MapInfo Professional to design its paging and wireless data networks across Canada, said Northwood. Industry Canada is playing a key role in the development of deciBel Planner. Northwood is a strategic partner of MapInfo Corp. (888) 886-0381.
Celwave
A log periodic dipole antenna, the Celwave Maximizer model APL 926513, was introduced for Global System for Mobile communications and Total Access Communications systems. The antenna offers a 45 dB minimum front-to-back ratio. The Maximizer operates at 870 to 960 MHz, has a 65 degree horizontal beamwidth and 13 dB gain. (800) 235-9283.
Star Micronics
The MUT-03B was added to the MUT series of transducers from Star Micronics America Inc., which are well-suited for use in cellular and mobile phones. The 03B has many of the characteristics of other transducers in the MUT family, including a small footprint, side sound port, low profile and the ability to produce various intermittent tones so users can customize the sound for different products or brands. Sound output of the MUT-03B is 87 dB minimum at 10 cm. The nonwashable transducer operates at up to 4.5 volts, with a rated frequency of 2670 Hz. The MUT-03B weighs 1 gram and measures 13 millimeters wide by 15 mm long by 3 mm high. Depending on the quantity purchased, the MUT-03B can cost less than $2. (800) 782-7636.
AirLink
Wireless Ace, a graphical user interface for configuring AirLink Communications Inc.’s Cellular Digital Packet Data service-based Raven and PinPoint modems, now is available for use with Microsoft Corp.’s Windows 95 and Windows NT operating systems. The GUI allows users who have loaded a new version of the Raven or PinPoint firmware and installed Wireless Ace on their computer to configure and retrieve status information from remote modems. Raven frequently is used to access remote terminal units in the oil, gas and water industries and other commercial applications, such as telemetry, dispatch and public-safety, said AirLink. PinPoint contains a CDPD modem and a Global Positioning System receiver for applications including automatic vehicle location and asset tracking. (513) 759-9861.
Antx
Companies with equipment at unattended operations could use the ADAS DiaLog alarm monitoring and notification system from Antx Inc. that automatically phones or pages up to 16 numbers from a one or a series of alarm conditions. DiaLog alarms would be activated by changes in conditions or controls at places like pump and compressor stations, fire and security systems, cellular tower sites, computer rooms, hatcheries, freezers and electrical substations. DiaLog continues to call, giving user-recorded messages until all alarms are acknowledged to ensure that personnel are notified of critical conditions. Features includes phone, pager, radio or modem notification, call-back alarm acknowledgement, remote programming, remote call-in for status, NEMA 4X enclosure, up to 40 alarm points monitored continuously, event logging, 24-hour battery backup, local programming through keypad, and local visual display of system and alarm status, said the company.

SmarTrunk Systems
SmarTrunk Systems Inc. introduced its SkyLink Wireless Local Loop System designed to provide last-mile connection in rural and remote areas. The modular and scalable system can be profitably installed and operated with as few as two channels and 50 subscribers or as many as 24 channels and more than 1,000 subscribers, said SmarTrunk. The WLL system employs macrocell technology that can cover a wide geographic area from a single cell site, reducing the cost of the base infrastructure in rural, low-density applications. SkyLink is available in frequency bands from 130 MHz to 800 MHz. (510) 887-1950.
