Currently FCC (for operation in the US) models and CE (for operation in EU and other countries using CE certification) models are available. If in doubt, consult your local experts before ordering. The FCC model is restricted in its operation to the 3.1-10.6 GHz range of frequencies. The CE model is restricted to 6-8.5 GHz band and to stricter out-of-band emissions. Operating Walabot in conjunction with other wireless devices In some cases your projects may contain both Walabot module and an additional wireless device for communications in proximity to each other. It is best to configure the devices such that their frequencies of operation do not overlap. For example, if the FCC model of Walabot is used in conjunction with a WiFi module, it is the safest to configure WiFi to operate in the 2.4 GHz band, rather than in the 5 GHz band. If you configure Walabot to use 3.3-4.8 GHz subband or the 6.3-8.3 GHz subband (as in CE models), both 2.4 and 5 GHz bands of WiFi are safe to use. Bluetooth, Zigbee and cellular bands are all below 3 GHz and should pose no mutual interference challenges. We recommend trying to locate the modules far away from each other. If you have any issues, feel free to contact us at support@walabot.com Accessories Walabot has several optional accessories:
Case (included with the Pro model) Ferrite-loaded USB cable for a power supply. This accessory is recommended for uninterrupted operation when Walabot is powered by an external power supply and the mains voltage is prone to surges. Technology The Walabot products are multi-antenna sensors that characterize the environment in the vicinity of the sensor. It is done by collecting and analyzing propagation information between the antennas, which is affected by the environment. The propagation response information is collected by Walabot and processed at the hosting device to obtain spatial information about the environment. Installation Installation of Walabot includes the following steps Selecting a powering option Mechanical placement Connecting Software installation Selecting a powering option The Walabot Pro and Maker have two USB connectors one is used for data transfer and possibly powering the Walabot, and the other USB connector is for power only. [describe here the criteria for deciding how to power Walabot]. Select your power source for Walabot using the jumper on the back side of Walabot board. In the figures below you can see the jumper position for powering through the main (blue) or the auxiliary (green) USB port. Data acquisition RFICHost deviceEnvironment to be sensedUSBWalabot When you are at the point in your project where you would like to place the board in a case, you will need to experiment with the powering option and place the jumper accordingly. By default, the board is configured to provide power using the main USB port. Mechanical placement Eventually, as your Walabot board becomes part of your project, youll want to secure it in a safe and convenient place. Several options are possible. We supply an optional protective case, which can be used to host the Walabot board. This case comprises a magnetic mount on its back, which enables it to attach to iron surfaces. We supply a stick-on metallic ring which can be placed on your cellphone, or your robot, or the wall of your lab, so that you can attach and detach Walabot easily. You can fix Walabot to the surface of your project, or to its cover. Make sure that the front cover is nonmetallic (e.g. plastic) and preferably thin (not exceeding 2 mm). You can temporarily use the board as is, but be aware that it can get damaged, and the USB connectors may degrade due to repeated strain. In the case of temporary use of bare board, be sure to lay it on a non-conducting surface, to prevent an electric short. Mounting Walabot in the case

In most cases it will be a computer, laptop or desktop, a tablet or a cellphone. The board connects to the hosting device through a USB cable. Walabot is supplied with a short USB cable suitable primarily for attaching the Walabot to a cellphone or a tablet. Alternate cables can be used. If you prefer to use the auxiliary port for powering the board, you may attach the board to the additional power source, such as a power pack or a charger. If a wall charger is used, it is advised to use a ferrite-loaded cable [refer to exemplary model type]. Connect the data USB to a hosting device. If needed, connect the auxiliary USB port to the external power source. Software installation Walabot is operated by application software that needs to be installed on your host device. A variety of applications and software resources for developing your own applications are found on the Walabot web site at the address [ADDRESS COMES HERE]. Download the relevant applications, according to the type of your host device and its operating system (Windows, Android etc.). If relevant, download the appropriate software to begin developing your own applications. The software contains a driver through which the application software communicates with Walabot device. The driver translates your commands into Walabots actions. Moreover, the driver is in charge of enforcing certain regulatory restrictions. Be sure to communicate with the Walabot device only through the driver using the provided API. The documentation of the API is found at [ADDRESS COMES HERE].
