Successful Field Test of High-Power 3.2W Wi-Fi for Industrial Wireless Communication

Overview Bemap, Inc. (the "Company"), in collaboration with Kirin Brewery Company, Limited, NTT Broadband Platform, Inc., Cisco Systems G.K., and Edgecore Networks Corporation, has conducted a wireless communication field test at Kirin Brewery's Sendai Factory using high-power access points. This test aims to anticipate the upcoming regulatory changes for the 6GHz SP (Standard Power) mode in Wi-Fi, confirming its effectiveness in a factory environment.

Background and Objectives To verify indoor and outdoor wireless characteristics, the experiment utilized the "SP Mode," which has already been introduced in the U.S. and is currently under preparation for release by Japan's Ministry of Internal Affairs and Communications. While SP Mode allows up to 4W of output, this test was conducted at 3.2W, setting it well within compliance with Japan's Radio Law. After obtaining an official "Experimental Radio Station" license, the test aimed to compare communication areas and quality across different output modes.

Test Methodology The experiment compared communication characteristics among VLP (Very Low Power), LPI (Low Power Indoor), and SP (Standard Power) modes. The setup utilized Cisco's CW9179F as the main AP and Edgecore Networks' OAP101-6E as the client device, measuring range and quality (throughput, latency) both indoors and outdoors.

Results While the conventional VLP mode experiences signal drops below practical levels under 100 meters, the SP mode maintained signal levels in the -70dBm range beyond 500 meters. The experiment confirmed a throughput of 200Mbps even at 600 meters from the main AP, proving that the usable range for Wi-Fi in large-scale factory operations is significantly expanded.

Future Prospects Based on these results, the Company will provide technical evidence to contribute to the advancement of Japan's wireless communication infrastructure. Plans are underway to establish specific use cases tailored to factory operations and to extend design guidelines for high-power Wi-Fi into broader sectors, including logistics and energy.
