There must be a survey of the construction environment and know the corresponding scale

Label the obstacle information as detailed as possible, keeping it consistent with the actual environment.

The customer's needs must be clear, and the actual number of people needs to consider the concurrency rate according to the actual situation.

For some unclear information, the surveyor is required to estimate relevant information for surveying.

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.

The joints on the AP/power splitter/coupler/combiner/antenna are generally N-type male heads, and the two ends of the feeder are generally N-type female heads, and the two are connected to each other.

Under normal circumstances, the indoor system or the longer distance (greater than 50 meters) uses 7/8 lines, and the tributary or short-distance transmission uses 1/2 feeders.

1/2 super soft feeder is very thin and flexible. It is generally used in the case where the gap is small or the turning angle is large.

When the actual project calculates the feeder, the short feeder can directly calculate the number of standard feeders. After the long feeder needs to confirm the routing path, reserve 10%.

AP8030DN cannot be connected to an external antenna.

AP6610DN supports PoE power supply

AP8130DN has 4 RF ports

AP6510DN supports 11a/b/g/n/ac protocol

The number of antennas in a single AP band is 4~8, and it is recommended that no more than 10 antennas under normal circumstances.

Under normal circumstances, the distance between the AP and the far-end room sub-antenna is controlled within 50 meters, and it is recommended not to exceed 60 meters.

In a typical room sub-scenario, it is recommended that the output power of each antenna be basically the same, and the output power is controlled at 12~18dBm. The specific power selection and field

Strong demand is related to the wall structure

There is interference between the room division antennas of the same AP, so it cannot be placed intensively according to requirements.
