As SOFTBANK MOBILE began to advance the installation of wireless LAN spots in homes and stores, KDDI will become the largest public wireless LAN service in Japan "Au Wi-Fi SPOT"As mobile phones companies are proceeding with the installation of wireless LAN spots to respond to the increase in traffic volume due to the spread of smartphones, etc., it is clear that Kyushu University and others succeeded in making the whole area of ​​underground shopping mall a wireless LAN became.

We succeeded in lowering the installation cost, and handover was also realized.

Reduce the cost of WiFi throughout the underground shopping street with original radio relay technology | Press Release / MIMO-MESH Project


Research on low-power radio communication system that can be introduced at low cost, with Kyushu University, Kurume National College of Technology, Kyushu Institute of Technology, and several companies participating, with Professor Hiroshi Furukawa of Kyushu University Institute of Systems Science as a research representative According to the press release announced by the MIMO-MESH Project, the entire area of ​​the underground shopping street "Tenjin underground shopping street" located at the center of Fukuoka city (1.2 km, the number of users per day is 400,000 people) He seems to succeed in spotting.

This is a wireless LAN access point with wireless relay function adopted "Professor Hiroshi Furukawa's" wireless backhaul technology "where access points mutually relay each other on a wireless LAN"PCWL-0100Although it took a lot of LAN cable wiring to construct a wireless LAN spot in a wide range, it became unnecessary to wire wired between the devices, so that it was necessary to lay LAN cables Reduce this cost to one-seventh or less.

"PCWL - 0100" main unit. Compatible with IEEE 802.11 b / g, the housing size is 142 mm × 118 mm × 39 mm and the weight is 450 g and compact.


Building a network is very easy. "PCWL - 0100" can be connected by wireless with one button.


You can add an area with only one button. The "L2 handover function" is implemented in "PCWL - 0100", and even if you move to the different "PCWL - 0100" area, you can maintain connection without disconnection. It covers the weak point of "It will expire when moving to another access point" of the wireless LAN access point.


The wide area wireless LAN spot constructed this time can absorb the mobile communication traffic which is rapidly increasing with the spread of smartphones, contribute to the quality improvement of the existing mobile phone network, and furthermore as future prospects, By using it to operate applications for new mobile devices, we will support the revitalization of the next generation content market.
