32. Our business: Communication revolution

Global communication has shifted from being primarily voice(telephone) to being primarily data.
The reason communication charges are highis because of the excessive quality requiredfor voice (telephone calls)!

Hey hey!

Communication
fromvoice todata!

It's noisy!

Crosstalkis noisy！

Wi-Fi (IEEE802.11) will move to the 7th generation in May
2024 (low price, low carbon, ultra high speed)
Communication performance equivalent to 30 optical fibers(maximum speed is 46Gbps)

30GbpsEquivalent to 30
optical fibers!
No need forfiber optics
anymore! ?

No matter how long you wait, 5G will not come to your town!
①The installation cost is 2.5 to 3 billion yen per hectare!
②Just under 40% are Chinese patents (not adopted by the US)③ Concerns about health hazards due to high electric field strength④ Since standards differ in each country, it cannot be called aninternational standard.

WELSOC’s Business Domain 3 Division
Our business will be summarized into three categories: (1) Wi-Fi base station that realizes
inexpensive and robust regional communication infrastructure using Wi-Fi and LPWA tosupplement the existing communication environment, (2) binding services and binding that
become more effective as communication costs are reduced, and (3) HW subscription
services, a hardware subscription service that becomes feasible as communication costs arereduced.

Even between the same nodes, if the frequencies
used are different, the wireless metric will change.

Send request packets
on all Wi-Fi interfaces

Choose a Wi-Fi interface with a low
radio metric value

If the wireless metric values are
the same, select the Wi-Fi
interface with the earliest
request arrival

The radio metric value increases as
the communication distance increases.

1, Exchange radio metrics with each neighboring node

The metric value of the selectedroute is 20 (= 10 + 10)

3, Route selection by destination node2, Wi-Fi interface selection

Notification of decisionroute in response packet.

4, Route determination by response packet

Wi-Fi Base Station
DesignWe design equipment with both weatherproof and radio
frequency performance specifications to withstand long-term
utilization as IT infrastructure equipment.
Weatherability
High weather resistance is ensured for long-term use.
The design will be resistant to natural disasters, based on ourexperience (3 years) of installing and operating Wi-Fi equipment onMiyako Island, Okinawa Prefecture, where extremely strong typhoons
pass through every year. We will also take measures to prevent salt
damage in coastal areas.

Radio performance
The design shall be based on Wi-Fi6-compliant models.
Given the current trend of longer delivery times for related
equipment due to the recent semiconductor shortage, weare working to secure equipment as our own inventory.

Automation is urgent as agricultural workers are aging!
 DX of agriculture using Wi-Fi communication

The various communications based on the introduced Wi-Fi canbe used for agricultural DX.
Wi-Fi Base Station

Unmanned operation of cultivator⇒ The situation at the scene is
distributed via camera video.

agricultural drone⇒ Pesticides, fertilizers,
seeds etc.

Cooperation withshipping factories

base station camera⇒ Growth, growth, field situationAI
AI image analysis⇒ Risk analysis ofpests, etc.
