Is it unavoidable for the connection to drop when using Wi-Fi while walking?

Is it unavoidable for the connection to drop when using Wi-Fi while walking?

[Application Case] Demonstrating the Truth and Lies of Wi-Fi

In an office with multiple Wi-Fi access points (APs) that have the same SSID, I connected to an AP at my desk after arriving at work. After that, when I moved to the conference room, I automatically connected to the AP in the conference room without having to perform the connection operation again. This process of moving between multiple APs with the same SSID while carrying a device is called roaming. 【Product Introduction】 ■ Radio Shielding Box MY1530 ■ High-Speed Programmable Attenuator MAT810 *For more details, please refer to the PDF document or feel free to contact us.
