How to select antennas for APs

Antennas receive and send radio signals. Select antennas for APS by referring to HUAWEI Access Points Antenna Quick Start. Contact Huawei local offices to purchase antennas. Antennas from other vendors are not recommended for working with Huawei APs.
Consider the following points when selecting antennas:
1. Usage scenario and purpose
Indoor antennas are generally used to provide signal coverage in indoor scenarios while outdoor antennas are used to provide signal coverage and bridging backhaul in outdoor scenarios.
2. Local standards and regulations
The transmit power and maximum gain of antennas must strictly comply with local standards and regulations.
3. Shape and distance of the coverage or backhaul area
- Coverage: Directional antennas are recommended in long and narrow areas while omnidirectional antennas are recommended in round and square areas.
- Backhaul: Directional antennas are usually used. If the backhaul distance is long, use high-gain antennas; if backhaul targets are concentrated, use small-angle antennas.
4. Signal transmission band (2.4 GHz/5 GHz)
- Coverage: To provide 2.4 GHz and 5 GHz signal coverage, use 2.4Gand 5G antennas in the same area or use dual-band antennas.
- Backhaul: Only 5 GHz antennas are used for backhaul.
