Spread-Spectrum Radios
Spread-spectrum radios are very popular for creating wireless communication links to and between data loggers. These low-cost devices provide robust links ranging in speeds from 10 to 200 kbps and distances of 3 to 50 miles, depending on the radio model and operating conditions. These radios consume little power and are easy to install and maintain, as they have been designed for low-power, non-licensed operation.

Frequency Hopping Spread Spectrum
FHSS
Futaba introduced FHSS (Frequency Hopping Spread Spectrum) systems in 2010, to offer modelers a less expensive way to enjoy 2.4GHz dependability. Other advantages include extremely low latency, exceptionally fast frame rates, transmitters with no external antennas and low-cost receivers with Easy Link convenience.As the name implies, the transmitter signal of an FHSS system literally hops from frequency to frequency in a pseudorandom sequence. The combination of frequency hopping with Futaba's advanced algorithms creates 100% frequency security.

SAR Testing
RF transmitters used in close proximity to the human body must be evaluated against human Exposure standards which set basic restrictions for the Specific Absorption Rate (SAR) of RF energy by any part of the human body. This may include two-way radios, cellular phones, smartphones, spread spectrum, Bluetooth devices, wireless EFTPOS terminals and WLAN devices used in PDA/notebook/laptop/tablet computers. In Australia and Europe, virtually all devices exceeding the power threshold of 20mW (13dBm) and used in close proximity to the human body must comply with SAR requirements. There is no such blanket exemption in the USA and Canada where each product must be assessed against frequency/power level criteria.

Vantage PRO2 Davis
6152 & 6152C
*Refresh Rate – A packet of data is sent from the outdoor transmitter to the receiver every 2 1/2 seconds! This means when you look out the window and see the wind blowing, the weather station will reflect it almost immediately.*Transmission Distance (wireless models) – The first in its consumer price range to use frequency hopping spread spectrum radio technology, the Vantage Pro2 can transmit and receive data up to 1000′ (300 m) line of sight. This is a much greater distance than most other weather stations. This technology also provides improved reception through multiple walls and greater immunity from RF interference.

PCIE Module For PCIe Bus Expansion
PCI113
PCI113 is VadaTech second generation PCIe expansion module. The PCI113 is a high-speed 20Gbps bridge from the host PCIe bus to VadaTech’s carrier and Rear Transition Module (RTM) products such as the ATC104/114/118/117/119, ART114, μTCA chassis, etc. The different carriers host different I/O modules such as PMC/PrPMC, AMC, PCI-X and PCIe edge modules. This concept allows any of the available I/O modules in these standard form factors to be integrated quickly and easily into an AdvancedTCA or μTCA subsystem. The PCI113 allows expansion among multiple μTCA chassis or expansion into other chassis that are not ATCA or μTCA based.The PCI113 is a single module PCIE based on the PCISIG specification. The PCI113 provides a PCIe x4 link infiber/copper via front panel QSFP. The dual front I/O allows expansion into two separate systems independently. The upstream port must not have spread spectrum PCIe clock enabled.

Silicon Oscillators
Analog Devices silicon oscillators are frequency programmable via pin-strapping, or through the resistor connection or serial interface (SPI or I2C). These solid-state clocks are well-suited for general-purpose usage, such as PGAs, ASICS, microprocessors, or UARTS, and they operate from 1 kHz to 170 MHz. Silicon oscillators are also ideal switching regulator clocks as they provide synchronization and EMI reduction (via spread spectrum).

Acoustic Modem Option for Control Module
Gavia AUVs can be fitted with the Teledyne Benthos ATM-900 Acoustic Modem. The ATM-900 Series Acoustic Telemetry Modem is the most advanced, multipath and noise tolerant, modem available. They are designed to meet both the high data rate requirements of commercial users, and the higher reliability, lower data rate requirements of the military. The modems employ two modulation techniques: phase shift keying (PSK), which provides the highest bit rate, and multiple frequency shift keying (MFSK), which provides reliability in a multipath environment, or when the modems are required to operate in a low signal-to-noise (SNR) environment. The ATM-910 Series can transmit data using PSK modulation for reception by a Gavia Modem Deckbox, but receives data using MFSK modulation only. MFSK modulation is a spread spectrum modulation process that transmits multiple tones simultaneously.
