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).
