Introduction
The Xeta Radio family is a small form-factor data radio designed for transmitting low to moderate speed
data across distances of up to 100 miles. Thus, this radio family has a much longer range than Wi-Fi or
other short distance radios, but at a lower data rate capacity. The radio also has several unique features
including the ability to operate from 406.1 to 430 and 450 to 512 MHz, 470 MHz maximum for Canada.
The radio has a guaranteed delivery licensed mode. In fact, since the radio is software defined, as
changing environmental conditions can cause variations in performance, the radio will automatically
adjust its operating parameters to maximize performance. Thus, if the signal quality degrades, instead
of stopping all transmissions, the radio will reduce data rates, change modulation methods, increase
power levels, change frequencies, or enact other modifications to maintain the best data link possible
given the conditions iaw the licensee’s allowed conditions. The design of the radio also includes a
physically small size, low weight and very low power consumption while maintaining a robust design
over extremes in environmental conditions.
XETA4
The XETA4 is the 400MHz version of the Xeta family.
The XETA4 includes standard modulation methods such as GMSK, 2-level FSK, 4-level FSK, 8-level FSK as
well as 2-level, 4-level and 8-level PSK and 16-QAM. Because the Xeta series radios have a software
defined modulation and detection system, additional modulation methods may be added in the field
allowing the radio to benefit from future advances in the industry.
The OEM board has two connectors: one MMCX for the RF signal and one 24-pin header for the user
data interface and power. The user data interface connector includes the 4.0-7.5V power for the radio,
one standard speed diagnostics/control serial interface of up to 921kbps, one high-speed data serial
interface with hardware flow control and several user-definable digital signals.

Master terminology indicates the control station or control point for a network.
XETA4 Installation
The XETA4 is a board level radio that is intended to be integrated into a customer package. As such the
antenna placement must be done in a manner that is in compliance with all local regulations.
All transceivers sold under the FCC ID PEJ-### must be installed professionally. This transceiver is only
approved for use when installed in devices produced by Xetawave LLC or third party OEMs approved by
Xetawave LLC. This transceiver must be installed in a NEMA enclosure.
