DS-3WF03C User Manual
3. Embedded hardware watchdog
DS-3WF03C is embedded with hardware watchdog, which is used to monitor the
working status of the device. Once the system is not working properly, the
DS-3WF03C device can be rebooted to guarantee the stability of the system.
4. Software Ping watchdog function
DS-3WF03C software ping watchdog function enable the device periodically ping
another device associated to, so that it can detect if the system is working well. If
the wireless link is lost or there is any problem, the device is rebooted. This is
important because the devices can be restored to work automatically if there is
any problem, and avoid the extra human labour to maintain the outdoor devices.
5. More Non-standard channels availability
Currently most of the WiFi devices are working at standard 802.11 5.8GHz
frequency. However, standard 802.11 5.8GHz only provide limited channels, and
there is serious interference if there are a lot of 5.8G WiFi devices nearby.
DS-3WF03C support more channels near 5.8GHz band, and spread the band to
non-standard frequency part: 5745MHz-5825MHz (4920MHz-6100MHz) 。 The
advantage of working at the non-standard band is to avoid the interference in the
standard channels, and the wireless throughput can be improved.
Note: Please confirm whether those non-standard channels are permitted locally
before using them.
6. Outdoor industrial product
DS-3WF03C device can work at all kinds of outdoor severe environments,
including -30 to 75 degree temperature, 5% to 95% humidity, while maintain good
performance.
