How Can We Help?
Which network or protocol is SyncSign using?
- The Hub is using both Wi-Fi (802.11b/g/n) and ZigBee (802.15.4), while those Displays is using ZigBee (802.15.4) only.
- 7.5-inch comes with both ZigBee (802.15.4) and Wi-Fi (802.11b/g/n) built-in; Thus, it can download images resources on the Internet directly. It will support working without the Hub in upcoming firmware update (the battery life depends on how frequently it refreshes for new data).
