2. Q: how to distinguish between Wi-Fi and non-Wi-Fi phone?

A: From the appearance of the nameplate Wi-Fi phone with W and WAC, W supports 802.11g 2.4G band, WAC supports 802.11ac protocol 2.4G + 5G dual band. Wi-Fi settings can be detected from software,, the first time power-up Wi-Fi can be configured.

3. Q: How to use the bridging function?

A: In the normal network situation,telephone LAN port connected to the network cable, from the PC port cable to the computer, computers and phones can be simultaneously networked. This function can be used under the network cable only.

4. Q: Will Wi-Fi phones be unstable due to signal interference?

A: 2.4G interference will be more band interference, in addition to the interference of Wi-Fi channel itself, there are Bluetooth, microwave ovens, game consoles and other interference, Wi-Fi channel itself interference also less. However, due to the relatively small amount of voice data usage, the impact on voice calls when interfered is relatively small. If you follow our company's deployment instructions to deploy Wi-Fi phones and APs, stability will be better.

5. Q: How to choose the 2.4G and 5G band to deploy the phone?
A: 5G relative 2.4G advantage is less interference, the disadvantage is that the signal attenuation is relatively fast, the transmission distance is relatively close, so pure 5G band deployment costs will be higher, the stability will be better, 2.4G deployment costs lower, the stability will be slightly worse than 5G. According to a large number of actual use cases, 2.4G deployment will be more flexible in single AP environment.
If you use our dual-band phones, dual-band AP at the same time, 5G band used in the place that’s closer to AP, 2.4G band used to far away from AP, you can get the best results.
