The compact SMT module, measuring about 22 x 34 mm, operates in the 863 - 870 MHz frequency band (K, L, M, N, Q/R) and combines tuned Surface Acoustic Wave (SAW) filtering as well as intelligent Listen Before Talk / Adaptive Frequency Agility
(LBT/AFA) technology to avoid connectivity issues caused by external radio interference.
The frequency agility
of SCRN-220 provides investment protection to mobile operators if they ever need to change the spectrum being used for enterprise LTE small cell networks.
The Department of the Navy is investing in new technologies and developing updated policies that will facilitate maximized spectrum efficiency, including improving the ability to coexist with other systems in the same band, and increasing radio frequency agility
The new wireless RF AMI network will leverage best-in-class signal range and unparalleled frequency agility
to serve as a powerful platform to support advanced functionality including remote meter disconnects, pro-active outage notification and prepay metering.
AESA radar offers greater frequency agility
than conventional radar systems, including Passive Electronically Scanned Arrays (PESA), which delivers unpredictable scan patterns that are difficult to detect by radar warning receivers (RWRs), particularly older systems.
Among other interesting features is the uPoint Robot Radio, which, said the company, leverages frequency agility
-- the ability to automatically switch away from congested frequencies -- power management, and mesh networking to form a robust network in which robots, operators, and observers work seamlessly together.
Hayes, "Microstrip antennas with frequency agility
and polarization diversity," IEEE Trans.
is typically provided by scaling the antenna dimensions physically or electrically.
An intrinsically narrowband antenna with dynamically controlled frequency response easily achieves the frequency agility
The company said that its low cost, low-power module is based on Analog Device's ADF7023 transceiver and includes Listen Before Talk (LBT) and Adaptive Frequency Agility
(AFA) technology, which allows channels to be automatically changed if interference is detected and automatically finds the best channel to improve network performance.
These radios now also include Time Division Multiple Access (TDMA) capabilities for advanced Battle Management Systems (BMS), providing simultaneous time-critical situational awareness and voice communication across networks of 64 radios, as well as a Free Channel Search capability for enhanced frequency agility
in high-noise or jammed environments.
By operating above the regular CATV signals and providing frequency agility
between 800 MHz and 1500 MHz, additional network controllers can be added to support even more clients to the network.
