1.6 AT command support
The ODIN-W2 series modules support AT commands as described in the ODIN-W2 AT Commands Manual [1].
See also the s-center software, which is an easy-to-use tool from u-blox for evaluating, and configuration of
u-blox Short Range modules. The s-center tool is available for download on the www.u-blox.com website.
1.7 IEEE 802.11d and additional regulatory domains
The ODIN-W2 series modules support IEEE 802.11d. IEEE 802.11d is an amendment to the IEEE 802.11
specification that adds support for "additional regulatory domains". IEEE 802.11d allows ODIN-W2 based
devices to self-configure and operate according to the regulations of the country in which they operate. Its
parameters include country name, channel quantity and maximum transmission level. The country information
feature simplifies the creation of 802.11 wireless access points and client devices that meet the different
regulations enforced in various parts of the world.
1.7.1 ODIN-W2 IEEE 802.11d implementation description
When ODIN-W2 is used as a Wi-Fi station, the scan is used to detect which regulatory domain it is currently in.
Passive scan is used for channels that are not available in all regulatory domains. The device supports the
following three domains, where WORLD means all channels that are supported both by FCC, ETSI and most
other countries in the world:
•WORLD
•FCC
•ETSI
See Table 3 for detailed information on channels that are supported in the different regulatory domains. The
state transition diagram below (Figure 2) describes the algorithm for selecting the current regulatory domain.
Figure 2: ODIN-W2 series IEEE 802.11d state transition diagram
Initial regulatory domain is WORLD. At start up a scan is initiated to detect beacons containing country
information IEs.
If at least one scan result contains country information indicating FCC and no country information indicates ETSI,
then the regulatory domain is set to FCC.
If at least two scan results contain country information indicating ETSI and no country information indicates FCC,
then the regulatory domain is set to ETSI.

If the scan result contains country information indicating both FCC and country information indicating ETSI, then
the regulatory domain is set to WORLD. In the state transition diagram this is the state WORLD_FINAL. This state
will not be exited until the device is reset.
A new scan is performed every hour to update the regulatory domain.
If the current regulatory domain is ETSI and at least one scan result contains country information indicating FCC
and then the regulatory domain is set to WORLD. In the state transition diagram this is the state WORLD-FINAL.
This state is will not be exited until the device is reset.
If the current regulatory domain is FCC and at least one scan result contains country information indicating ETSI
and then the regulatory domain is set to WORLD. In the state transition diagram this is the state WORLD-FINAL.
This state is will not be exited until the device is reset.
At restart of the device the algorithm is restarted. It is not possible to override the algorithm described by
reconfiguration the device.

Table 3: Channel list for supported regulatory domains
The maximum output power is reduced on some channels depending on regulatory requirements. For example,
frequency band edge requirements can limit the output power on channels close to band edges.

2Interfaces
2.1 Power management
2.1.1 Module supply input (VCC)
The ODIN-W2 series modules must be supplied through the VCC pin by a DC power supply. Voltage must be
stable, because during operation the current drawn from VCC can vary significantly based on the power
consumption profile of the Bluetooth/Wi-Fi technologies.
2.1.2 Digital I/O interfaces supply output (V_INT)
The ODIN-W2 series modules provide a 1.8 V supply rail output on the V_INT pin, which is internally generated
when the module is powered on. The same voltage domain is used internally to supply the generic digital
interfaces of the modules. The V_INT supply output can be used instead of an external discrete regulator. See
the Electrical specification section for maximum output current.
2.2 Antenna interfaces
The following two different antenna options are available in the ODIN-W2 series:
•ODIN-W260 equipped with dual U.FL. coaxial connectors for external antennas. Different types of
external antennas are available and can be used.
•ODIN-W262 equipped with an integrated dual-band antenna
While mounting the unit, ensure that it does not interfere with radio communication. The ODIN-W262
equipped with an internal surface mounted antenna should not be mounted in a metal enclosure. No
metal casing or plastics using metal flakes should be used. Avoid metallic based paint or lacquer.
See ODIN-W2 series System Integration Manual [2] for information on the external antennas that can be used
and for other RF and antenna design advices.
2.2.1 Antenna connectors and internal antenna
The ODIN-W260 module has two RF antenna U.FL. coaxial connectors with a characteristic impedance of 50 Ω.
The main antenna connector supports both Bluetooth and dual-band Wi-Fi. The second (MIMO) antenna
connector adds support for 2x2 MIMO 2.4 GHz single band Wi-Fi.
The ODIN-W262 module has an internal dual-band PIFA antenna and supports Bluetooth and dual-band Wi-Fi
(SISO).
