Selecting APs and antennas based on site conditions

13

Huawei APs include indoor, indoor distributed, and outdoor APs. Select appropriate APs and antennas based on customers' requirements for signal coverage and site conditions.
- Use indoor settled APs with omnidirectional antennas in indoor environments with small areas, dense users, and high capacity demands, such as meeting rooms, offices, airports, and bars. Use indoor distributed APs to provide hotspot coverage in indoor environments with a small number of users, such as office buildings, hotels, and dormitories. Select APs based on customer requirements.
- In outdoor scenarios, use high-power outdoor APs with high-gain directional or omnidirectional antennas. Directional antennas are usually placed on building roofs to provide signal coverage for opposite buildings. Omnidirectional antennas can be placed in open areas such as parks and residential communities.

How are APs and antennas selected based on site environments
Huawei APs include indoor APs, indoor DAS APs, and outdoor APs. Select appropriate APs and matching antennas based on customers' requirements for signal coverage. In indoor environments with a small area but a high user density, such as meeting rooms, offices, airports, and bars, we can choose indoor APs with omnidirectional antennas. In indoor environments with a low user density, such as office buildings, hotels, and dormitories, use indoor DAS APs to provide hotspot coverage. When outdoor coverage is required, use high-power outdoor APs with high-gain directional or omnidirectional antennas. Directional antennas are usually placed on a building's roof to provide signal coverage for opposite buildings. Omnidirectional antennas can be placed in open areas such as parks and residential communities. Select AP models and antennas based on the onsite environment and customer requirements.

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.

What's Site Selection Requirements
The TR should be At least 5 kilometers away from heavy pollution sources such as smelteries and coal mines. At least 3.7 kilometers away from medium pollution sources such as chemical, rubber, and galvanization industries. At least 2 kilometers away from light pollution sources such as packinghouses and tanyards. Away from industrial and heating boilers. Away from dusty roads or sand fields. If this situation is unavoidable, the doors and windows of the TR should not be facing the pollution sources. Away from livestock farms. If this situation is unavoidable, the TR should be in the upwind direction of livestock farms. Note that an old livestock room or fertilizer warehouse should not be used as the TR. NOTE: If one or more of these requirements cannot be met, ensure that the TR is situated in the upwind direction of the pollution sources. The air vents of the TR should be located far away from the exhaust of city waste pipes, large cesspools, and sewage treatment tanks. The TR should be in the positive pressure state. Otherwise corrosive gases will enter the TR and corrode components and circuit boards. The TR should be at least 3.7 kilometers away from the seaside or salt lakes. If this situation is unavoidable, the TR should be airtight and equipped with air conditioners. In addition, the salt-affected soil cannot be used as construction materials. It is recommended that the TR be on or above the second floor. If this is impossible, the ground for equipment installation in the TR should be at least 600 millimeters above the highest local flood record.

Can antennas in an antenna group on APs that support MIMO technology be used independently
Yes. When using independently, antennas using the MIMO technology cannot achieve the optimal performance. Multi-antenna MIMO technology can increase AP throughput and provide diversity receiving capability, improving the receive SNR.

Can I upgrade a specified AP
For V200R005 and earlier versions, you can only batch upgrade APs of the specified type or APs of the specified type in the same AP region. During AP login, if the software versions on the AP and AC are different, the AP is upgraded automatically.
