The path only supports importing nodes whose drawings are not larger than the original drawing.

The WLAN signal is not in the same frequency band as the GSM, CDMA, 3G and other signals, and the combiner has a high isolation, so the signal between different frequency bands

No interference with each other

Existing room division devices (power splitter/coupler/antenna) need to support the 2.4G frequency band of WLAN, otherwise the room division device needs to be replaced.

If the operator's signal can meet the coverage requirements, it can usually be satisfied after accessing the WLAN signal.

There must be a parallel topology relationship between the APs, and multiple APs are not allowed to be connected in series on one branch.

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

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

The office surveys the main load-bearing columns and partitions to cover the impact. If it is an overall suspended ceiling, the AP should be considered as close to the maintenance port, if it is metal

Ceiling, you can choose to place the AP under the ceiling or wall mount

If the wall of the school classroom is made of reinforced concrete, the signal attenuation is large. It is best to measure the attenuation when surveying. The teaching building should pay attention to the weak electricity room.

Set

The ward inspection scene has high requirements for coverage field strength, roaming effect, and bandwidth requirements. At the same time, it is necessary to pay attention to the interference or disallow of medical equipment.

Area with Wi-Fi signal

The stadium has a complicated environment and difficult wiring. Therefore, the weak house and the wiring should be confirmed with the property. If the distance is too far, it may be considered.

Adding an external switch, the survey should focus on mutual interference and installation methods between APs.

The purpose of 5G priority access in the AP is to reduce the 2.4G load and provide overall system performance.

Load balancing is suitable for high-density wireless network environments to ensure reasonable access of STAs.

Load balancing between APs, based on load balancing of access users or traffic, optimizing the distribution of terminals in the entire network and improving user experience.

Dynamic load balancing can be divided based on three factors: number of users, traffic, and type of service.

The APs that enable load balancing must be connected to the same AC, and the STAs can scan the SSIDs of APs that are load balanced with each other.
