The use of any antenna not listed above may damage the reader or adversely
affect performance.
Operation in Other Global Regions
For operation and use in the Rest of the World (ROW), there are two models, GX1 or GX2.

Installation
Because Speedway Revolution is capable of up to +32.5 dBm conducted power on the
housing RF connector, professional installation is required.
Operation in China, Israel, Indonesia, Malaysia, Singapore, and Vietnam
Regulations in these countries allow a maximum radiated power of 33 dBm ERP (Effective
Radiated Power) for high power RFID systems. The maximum Speedway Revolution output
power is determined by the following equation:
Maximum power setting (in dBm) = 33 – Antenna Gain (in dBd) + Cable loss (in dB)
For example, for an application with an antenna gain of 6 dBd and cable loss of 2 dB, the
reader output power can be set no higher than 33-6+2 = 29 dBm. The maximum transmit
power of Speedway Revolution is 32.5dBm measured at the RF antenna port.
Note:
It is important to apply the antenna gain expressed in dBd (dB with respect to a
dipole), which is equivalent to the isotropic antenna gain (in dBi) minus 2.15 dB. The
antenna gain used to set the output power must be the maximum linear gain of the
applicable antenna. Approved antenna vendors, model numbers, and associated gain are
listed in the following section.
Operation in Australia, Brazil, Hong Kong, New Zealand, Taiwan, Thailand, and Uruguay
Regulations in Australia, Brazil, Hong Kong, New Zealand, Taiwan, Thailand, and Uruguay
allow maximum radiated power of 36 dBm EIRP. The Speedway Revolution output power
may be increased to provide the maximum allowable EIRP subject to a maximum conducted
power allowance as well. The maximum conducted power at the antenna connector can be
no more than 30 dBm. The maximum allowable output power of the reader can be set to
satisfy both the conductor and radiated maximum criteria. The expression for the maximum
reader power setting is:
Maximum power setting (in dBm) = the Smaller of:
(36 – Composite Antenna Gain (in dBm)) OR (30 + Cable Loss (in dBm)),
where the composite antenna gain comprises the maximum linear antenna gain in dBi
minus any cable loss between the reader and antenna in dB. Approved antenna vendors,
model numbers, and associated gain are listed in the next section.
