Antenna analyzer covers 600 to 999
AEA Wireless’ CellMate EX antenna analyzer has been developed to cover the 600 MHz medical telemetry spectrum, the 700 MHz auction spectrum and cellular frequencies. The analyzer provides a graphical representation of VSWR and return loss and features EL backlighting, 15 non-volatile plot memories and a signal generator mode. It also works with the company’s Analyst Director Software for high-resolution plotting and archiving.
Multiband radio offers satcom IP
Harris now has an embedded, fully secure, satellite communications Internet protocol capability for its Falcon II AN/PRC-117F multiband multimission radio. The capability can be used in conjunction with either 25 kHz or 5 kHz UHF tactical satcom channels and provides transparent IP application support with full U.S. Department of Defense Type 1 security. The radio can optimize IP throughput performance over UHF tactical satcom channels by automatically adapting to dynamic channel conditions. The capability can eliminate the dependency on external interface boxes used to link to an IP network. The radio supports a standard, point-to-point protocol interface through the front panel of the radio, which can be cabled directly to a PC, router or other network device.
Terrain software offers 24 modules
SoftWright has released version 4.4 of the Terrain Analysis Package for Windows 9x/NT/W2K. This software consists of 24 modules that, when combined, bring a broad capacity of RF system design to the PC. This software is used to perform evaluations of existing or proposed radio transmitter sites, to predict radio coverage for TV and FM broadcasting, and to design cellular, paging and two-way radio systems. The fundamental module is the basic mapping module, which handles the path terrain profiling work. The RF facilities module can also be added.
UHF radio receives type acceptance
The RPU416A from Relm Wireless has received FCC type acceptance. It is a 16-channel portable. The lightweight radio comes with a rapid rate desktop charger and an 1,100 mAH, NiMH battery. Built-in features include priority channel scanning, CTCSS, DCS and two-tone decode and encode. The Mil-Spec RP series can be programmed using Windows-based software or can be cloned from a similar RP radio.
System works in emergencies
WorldCell and IDL have launched an emergency communications system, the satellite-based backup emergency communications network (BECoN). Leveraging the Iridium satellite network, the system can be deployed in cases of total infrastructure failure because it does not rely on ground infrastructure to complete a call. The system can be permanently installed or rapidly deployed in the field during a crisis. It enables communications between command centers, field teams and landline or mobile phones outside the affected region. The system consists of the base pack and the field pack.
GPS/AVL modem allows visual tracking
The KGP-2A/2B GPS receiver and modem from Kenwood Communications are ready for use with the 80 series or 60G series trunking mobiles. Designed to make AVL readily available through affordable access to GPS technology, the receiver is installed in a vehicle, incorporating a built-in modem with microprocessor control for base station and mobile unit coordination. One receiver is used for each base station. The radio connection, for two-way communications, is provided through conventional and trunking mobiles.
Vehicle repeater teams portables, mobiles
Midland Radio’s Titan vehicle repeater mounts into the chassis of a Titan mobile radio and integrates without external cables or add-ons, which allows portable users to communicate into their system. Using the repeater function, a portable transmission is received at 2 W and is then retransmitted by the mobile at that unit’s power level that could be as high as 110 W. So a portable user could potentially communicate with another person on the system from more than 40 miles away. The repeater retransmits incoming messages at 1 W, allowing a portable user to stay in communications with the base station from more than 1 mile away from the vehicle, depending on the conditions.
Encryption plugs into Motorola radios
Midian offers plug-in encryption for Motorola’s entry-level radios, the CT-25/450, Pro-3150 and the P040/080. The MOT-TVS-2-PRO-EL is a high-level rolling code scrambler, and the MOT-VPU-15-PRO-EL is a voice inversion scrambler. Midian’s TVS scramblers use a frequency hopping type of rolling code instead of frequency sweeping for higher security.
