WiFi Communication Plan for Robot Performances

WiFi network setup guidelines for robot standby and performance areas, including AP placement, channel configuration, and quality assessment (Chinese below).

WiFi Communication Plan 🔧

Network Coverage

Full coverage of robot standby and performance areas. Bandwidth ≥ 1G.

AP Quantity Guidelines

• AP coverage radius: 8 m; distance between two APs must be ≥ 16 m.
• Adjacent APs must use different channels.
• Example: a stage 10 m wide × 20 m long requires only 2 APs.

Network Quality Assessment

• Wireless side: channel interference < 3%; channel utilization < 40% (with no active downloads on-site).
• If current channel metrics do not meet the above requirements, manually change channels until utilization drops below 40%.
• Walk the entire area while continuously pinging the gateway; packet loss must be fewer than (number of APs − 1) packets.

Troubleshooting — If Issues Persist

1. If the robots and APs support 5 GHz channels 100 / 104 / 108 / 112, use them as first priority. Disable 2.4 GHz on all devices; set 5 GHz channel bandwidth to 20 MHz.
2. If the robots and APs support 6 GHz band, use 6 GHz as first priority. Disable 2.4 GHz on all devices; set 6 GHz channel bandwidth to 40 MHz.

Brand reference: ARUBA 635 supports 6 GHz + 5 GHz; ARUBA 535 supports 5 GHz.

Placement Notes

Line of sight:

• No obstructions between AP–AP or AP–robot pairs.
• Materials that do cause significant interference: glass, metal, solid brick.
• Materials that do not significantly affect signal: gypsum board, fabric curtains, cardboard boxes.

Mounting height:

• APs must not be placed beneath the stage; mount them at stage level (e.g., beside speaker cabinets).
• If suspended overhead, the AP must be no more than 4 m above the stage surface.
• Exceeding 4 m requires boosting transmit power, but results are not guaranteed.

WiFi通讯方案 🔧

网络覆盖

机器人候场及表演区域全覆盖。带宽1G及以上。

AP数量判断

• AP覆盖半径8m，两个AP之间距离大于等于16m。
• AP和AP之间信道一定不能一样。
• 比如：舞台宽度10米，长20米，需要2个即可。

网络质量评估

• 无线侧：信道干扰少于3%；信道利用率低于40%（现场无人下载的情况）。
• 如果当前信道指标不满足要求，需手动更改信道，使利用率低于40%。
• 全程走动，持续PING测网关，丢包数少于（AP个数 − 1）个。

如果解决不了，可采用以下方式

1. 如果机器+AP支持5G的100、104、108、112信道，优先使用；关掉所有设备的2.4G；5G频宽设为 20 MHz。
2. 如果机器+AP支持6G频段，优先使用6G网络；关掉所有设备的2.4G；6G频宽设为 40 MHz。

品牌参考： ARUBA 635支持6G+5G，535支持5G。

摆放注意事项

视距要求：

• AP和AP之间、AP和机器人之间无遮挡。
• 影响较大的障碍物：玻璃、金属、实心砖。
• 影响较小的障碍物：石膏板、布帘、纸盒。

安装高度：

• AP不能放在台下，需放在舞台平面上，例如音响边上。
• 如果悬挂于空中，距舞台台面不能超过4米。
• 超过4米需调大发射功率，但效果不一定理想。
