Wi-Fi Survey Service - Covering Allover Japan

We provide Wi-Fi measurement and diagnosis services that can be used to introduce a new wireless network solution, replace an existing wireless network, improve the current environment, and conduct surveys.
Using professional tools, we provide a report that visualizes site survey results in real-world measurements and drawings.

RSSI	SNR

Network Issue (Chnanel Interfere)	Comment
	・Both RSSI and SNR were good to captured in the various points. ・In the 5GHz band, points of high channel interference were seen. ・The 2.4GHz band is disabled on your Access Points. But some leakage signal from out of office have been captured. ・We present two suggestions for Wi-Fi tuning: 1. There are a lot of devices and APs in your office, and the channel bonding to the 80MHz bandwidth is enabled. If the devices use prior to Wi-Fi 5 (IEEE 802.11ac), it will become less effective. We recommend to disable it as the high-density design recommendations. 2. We recommend to set limits of strength on radio wave output for each AP since high channel interference were seen.
