Many of the GlobeSurfer installations are in remote sites where there is rare or no human presence. The device has to be remotely accessible 24/7 without interruption. A watchdog feature to monitor the connection will highly increase the reliability of the network connection and will decrease the frequency of on site human intervention.
The way it works is that if the modem is not receiving data after a pre-defined idling period, the Connection Watchdog will do domain name look ups to the DNS server of the service provider. If this operation fails, the 3G modem will be reset and the firmware will try to re-establish the connection.
As a complement to the Connection watchdog feature, the remote device control by SMS can further enhance the availability of the device.
In case the GlobeSurfer gets blocked due to unknown reasons, with the existing setup, the only way to remediate the connection is to manually power off and on again. This needs on site human intervention. In case the device can still respond to SMS, this feature can remotely restart the device by sending a SMS with the REBOOT command.
With this feature, the device can also achieve connection on demand through the START and STOP SMS commands. Principal applications are:
Security – network is only accessible by authorized people
Traffic limitation – traffic is only established during desired period
The Option XYFI is the world’s smallest personal 3G WiFi hotspot with 14.4 Mbps download and 5.76 Mbps upload, concealed within the form factor of a USB 3G modem. The unit can be used either as a regular USB modem, or can optionally be used to provide wifi coverage to additional clients when connected to a PC, or can be used as a standalone wifi router without the need for a PC. Also featuring a microSD slot the XYFI can be used as a portable storage device and media server.
At a glance
When combined with its wide range of accessories, the XYFI quickly becomes
a WiFi router
a Wifi repeater
a file server
Ideal for use in a number of scenarios, including:
Collaborative studying, playing, gaming
Secondary or temporary homes
The WiFi network created by the XYFI can operate in two modes, providing different levels of access to “trusted” users than to “guest” users, allowing trusted users to access the microSD storage whilst only allowing guests to browse the Internet, for example.
WiFi connections can be secured using WPA2 encryption and established using WPS so users do not need to remember SSID or passkey information. A maximum number of client connections can also be specified to ensure adequate Internet connection speeds.
SMS text messages can also be composed and managed via the XYFI’s web interface, providing pop-up notification of new messages.
The XYFI can also connect to other wireless networks, rather than mobile networks, to act as a wireless repeater, effectively extending the range of your existing wireless coverage.
The Media Server feature of the XYFI allows files to be uploaded to and downloaded from the microSD storage, providing mobile instant sharing and collaborative working possibilities.
The XYFI can also be administered from a mobile device, ideal for administrators if the unit is being used standalone without a connection to a PC. The built-in administration web interface re-sizes automatically to display on Smartphone browsers, be it iOS, Android, BlackBerry or Windows Phone.
Option XYFI will be available via our global and EU online stores in the coming weeks:
