XBee/XBee-PRO DigiMesh 2.4 RF Module User Guide

Worldwide acceptance

We manufacture and certify the XBee/XBee-PRO DigiMesh 2.4s to certain industry standards. These
standards enable you to understand what the devices can do and where you can use them.
The Federal Communications Commission (FCC) approves the devices for use in the United States. For
details, see United States
inherits Digi's certifications.
The devices are certified to operate in the industrial, scientific, and medical (ISM) 2.4 GHz frequency
band.
We manufacture the devices under International Organization for Standardization (ISO) 9001:2000
registered standards.
We optimize the devices for use in the United States and Canada. For a complete list of agency
approvals, see Regulatory

Antenna options

Digi devices come in a variety of antenna options. The options that allow you to connect an external
antenna are reverse polarity standard subminiature assembly (RPSMA) and U.FL. Typically, you make
connections with either a dipole antenna with a U.FL connection, or a U.FL to RPSMA antenna adapter
cable.
RPSMA is the more traditional antenna connector, however, if the device is going to be inside of an
enclosure, you would need to locate the device near the edge of the enclosure to allow the connector
to pass through an available bulkhead. The RPSMA connector uses the same body as a regular SMA
connector, but changes the gender of the center conductor. The female RPSMA actually has a male
center conductor. We equip the XBee devices with an RPSMA female plug, while the antenna is an
RPSMA male jack.
The U.FL connection allows for connectivity to an external antenna. U.FL is a small antenna connection
for use with a pigtail connector. A pigtail is a short (typically 4 - 6 in) cable that either terminates into
an external antenna port such as an RPSMA, N or TNC connection or an antenna. You would attach the
RPSMA connector to a bulkhead. These options allow you to mount the device away from the edge of
the enclosure in your product and centrally locate the radio. U.FL is fragile and is not designed for
multiple insertions without a specialized tool to separate the pigtail without damaging the connector;
for more information, see
ND/513034.
The other available antenna options are printed circuit board (PCB) and wire antennas. We form the
PCB antenna directly on the device with conductive traces. A PCB antenna performs about the same
as a wire antenna.
An integrated wire antenna consists of a small wire (about 80 mm) sticking up perpendicular to the
PCB. It uses a 1/4-wave wire that we solder directly to the PCB of the OEM device.
All Digi devices with antenna connectors have less than 0.1 dB loss; we do not consider one to be
"better" than the other in terms of reliability or insertion loss. RF device specifications such as -110
dBm receiver sensitivity, +3 0 dBm TX power, and so forth, already include any insertion loss due to
the soldered RF connector.
