HSB backup can be divided into real-time backup, batch backup, and scheduled backup.

The HSB jumper in the middle of the active and standby ACs is used to synchronize AP status, user information, and DHCP address pool information.

The heartbeat period of the HSB channel defaults to 1*3s, so the default service interruption time is 3s.

The heartbeat time and period of the HSB can be modified on the AC.

The CAPWAP link-off service maintenance feature enables online users to forward data packets when an AC fault occurs.

After the CAPWAP is broken, the AP allows the new user access feature to also be enabled in the tunnel forwarding mode.

AC dual-link cold backup feature can achieve 50ms carrier-class protection switching

HSB+VRRP dual-system hot backup can implement two high-reliability mechanisms: active/standby mode and load-sharing mode.

FIT AP is a traditional AP. In addition to providing basic wireless connectivity, it also provides security, management, and performance enhancements

FIT AP cannot be used in conjunction with AC

FIT AP differentiates from traditional FAT APs, providing only reliable, high-performance wireless connectivity, while stripping other features

FIT AP must be used in conjunction with AC

CAPWAP broken link service keeps the controller required to be directly connected to the network.

The CAPWAP broken link service keeps the controller required to be a side-by-side network.

CAPWAP broken link service keeps request forwarding mode is direct forwarding

The CAPWAP chain-breaking service keeps new users supporting all authentication methods online.

The WLAN and CATV signals are mixed by the signal combiner and input to the existing CATV cable, and transmitted to the CATV coaxial shielded cable.

In the room, finally separate the signals through the splitter panel to achieve indoor wireless network coverage and TV signal transmission.

The overall construction of WoC does not need to be changed too much, the construction impact is negligible, and the wireless coverage is better. It is excellent in wireless system transformation projects.

Obvious

Signal combiner and WoC panel, need to be customized separately from the partner

At present, the cable commonly used by CATV is SY(W) V75-5 coaxial cable, which is specially produced for cable TV. The transmission frequency of 2.4G is very small, so the distance from AP to terminal panel can be longer, but it is recommended not to exceed 500 meters
