ACT Communications Inc. developed two personal communications services and cellular protection products. The ACT 452-120-400L is a two-line, single phase surge arrestor that provides all-mode protection. The company said it is ideal for cabinet and PCS applications. It is rated to withstand up to 125,000 surge amps per phase. The ACT 422 is a bi-directional transient voltage surge arrestor, which protects equally against positive and negative surges on T1, telephone and data lines coming into the cell/hut site. Its breakover voltage is set from 17 volts for T1 to 265 volts for telephone, which allows for tight suppression voltage for each type of communications circuit, the company said. (903) 961-2300.

AccessLink, manufactured by Wireless Access Inc., is a narrowband personal communications services two-way messaging device that allows users to send, receive and reply to e-mail. The product allows users to create custom messages directly from the device using an integrated keyboard. Messages may be sent to other two-way devices, one-way pagers or any Internet e-mail address. Users also can respond to messages using one of several preprogrammed responses. The device is similar in size to typical one-way pagers, the company said. (408) 653-1555.

M/A-Com Inc. announced its family of drop-in ferrite products for cellular, Digital Cellular System and personal communications services markets. The products enable design engineers to anticipate board placement of passive devices in pre-development stages of wireless design, the company said. The drop-in products are designed to provide output protection on cellular base station subsystems such as combiners and amplifiers, in the duplexors on the output of each cellular base station’s transceiver and in interstage isolation in cellular base station high power amplifiers. (800) 366-2266.

Real Time Strategies introduced Load Sentry, a product designed to guard against paging system traffic overload and abuse. The system monitors incoming traffic and identifies traffic trends and abrupt changes in calling patterns, messages of excessive length, an unusual number of messages entered from any source and an unusual number of messages sent to any subscriber. Load Sentry’s configurable parameters allow system managers to define normal traffic in both peak and off-peak periods. Traffic found to violate established norms can be flagged for administrator intervention, trickled-out to prevent instantaneous overload, segmented into multiple transmissions or deferred until off-peak periods. (516) 939-6655.

Atlantic Solar Products Inc. introduced its SunMate solar electric generators, which are designed to provide continuous, reliable power in areas where conventional electricity is non-existent or unreliable. Typical applications are microwave repeaters, cellular phones, radio transmitters, fiber optics, cell enhancers and battery maintenance. The generators can be mounted on poles, towers, trailers, rails or on the ground. They are available in AC or DC configurations. (410) 686-2500.

Lightbridge Inc. unveiled its Retail Management System for converged retail environments. The point-of-sale tool is designed to help telecommunications retailers increase sales force productivity, accelerate and streamline customer acquisition and activation and analyze retail channel performance. The front office component of the system provides customers with credit screening, transaction and payment processing, service activation and cash drawer management. The back office component manages retail work flow including customer, inventory and purchasing management and store management reporting. (617) 441-4000.

Allen Telecom Group designed a repeater to improve fringe area and indoor coverage for Code Division Multiple Access systems. The EAC-800 CDMA Repeater provides coverage in areas such as tunnels, sports and convention centers, airports and parking garages. It also improves coverage in large buildings such as hospitals, apartments and office towers. The digital repeater picks up the downlink signal from an existing CDMA base station, amplifies it and re-transmits it to the desired area of coverage. Simultaneously, the repeater receives uplink signals from the handset, amplifies them and passes them on to the base station receiver over the same link. (216) 349-8400.

Illinois Superconductor Corp. will introduce two new base station filters for cellular and personal communications services at Wireless ’97 this week in San Francisco. The company said the filters address the need for range extension and site selection flexibility. The filters increase rural and suburban cellular base station coverage by 20 percent and extend cell site range and cell site number reduction by as much as 25 percent. (847) 391-9400.

Hewlett Packard Co. introduced a silicon monolithic amplifier that combines 21.5 dB gain and +8dBm output power at 1.9 GHz with unconditional stability and a special special positive-gain-slope characteristic. The gain of the amplifier has a positive-slope response over the 1 GHz to 2 GHz frequency range. This response can compensate for the gain `roll-off’ characteristics commonly found in receiver systems, the company said. (800) 537-7715, extension 9911.

Mitsubishi Wireless Communications Inc. introduced its MobileAccess phone, which provides circuit-switched Cellular Digital Packet Data in areas where CDPD service is not available. Created by the company’s Personal Mobile Communications division, the phone integrates an Advanced Mobile Phone Service cellular telephone with a wireless Internet Protocol modem, Internet/intranet applications and two-way paging. The handheld unit incorporates Interim Standard 91 authentication. (408) 774-3621.

Mitsubishi also introduced its AH-350 analog cellular phone, which provides three hours of talk time and 28 hours of standby time using a high-capacity nickel metal hydride battery.

The phone includes large `Send’ and `End’ keys, a three-line backlit display with double character height and two rows of icons and a battery level indicator. Features of the AG-350 include a built-in rapid charger, simulated dial tone and multiple language menu selection. (706) 654-9500.

Advanced Fox Cellular announced its Smart Travel Wall Charger. The OEM-style charger uses switching circuitry to maintain low temperatures and insure longer battery life. Models are available for the Motorola MicroTac and Elite, NEC P700, Nokia 101, Ericsson 237/337 and Oki 1335. (215) 322-4600.

SpectraLink Corp. announced a digital interface between its Pocket Communications System and Lucent Technologies PBX and key telephone systems. SpectraLink users now can access Lucent’s advanced calling features from their SpectraLink wireless pocket telephones, including directory lookup, calling line ID, calling party name, conferencing and multiline appearances. SpectraLink’s digital integration with Lucent systems is the latest in a series that includes digital interfaces with telephone systems from Nortel and Comdial. (303) 440-5331.

Motorola unveiled its PageWriter 250, the newest and smallest member of the PageWriter family of compact two-way pagers that communicate wirelessly with Internet e-mail addresses, fax machines and other one-way or two-way pagers.

The new model, featuring PageWriter’s signature QWERTY keyboard, allows users to create and send complete messages and customized responses. The company said the PageWriter 250 two-way pager is smaller than a deck of cards and is ideal for active, mobile users who not only need to receive pages, but also to respond to messages or even initiate messages directly from their pagers. Motorola said the pager’s keyboard makes it quick and easy to send messages, either to an individual or a group.

The pager also can access a range of information on demand from the Internet, scanning for important business-related data or information of personal interest, such as headlin
e news, stocks, movies, airlines and more. The text-entry pager op
erates on Motorola’s ReFLEX two-way paging protocol network. Future upgrades include group messaging, voice mail and dictated test messages. (817) 245-2000.
