We will exhibit at CareTEX Tokyo '24 (Summer) from July 30 to August 1.

A "portable intercom" with excellent robustness that connects via wireless LAN/LTE.

We propose a solution! It will lead to improved operational efficiency! The IP210H is a portable internal phone equipped with a transceiver function for IP telephony. It allows calls between devices on the same LAN, and by using an LTE connection, it can send and receive internal and external calls from anywhere within the mobile phone coverage area. Additionally, by utilizing the transceiver function, you can contact multiple devices simultaneously, enabling rapid information sharing. ■ Connect via LAN or LTE Devices on the same LAN can communicate with each other through an access point, and calls can also be made via an LTE connection. ■ Simultaneous calls possible You can interrupt a call with someone else without waiting for them to finish. ■ Smarter with Bluetooth functionality Using compatible earphones and microphones allows for active calls without worrying about cables. ■ Long-lasting large-capacity battery with approximately 30 hours of operation You can use it for extended periods without worrying about battery life. *In WLAN wireless device + IP wireless device mode (communication mode: wireless LAN).

• PBX/IP phone

Intercom compatible with wireless LAN/LTE connections, easy to install, and can work with various devices.

We propose a solution! It will lead to improved operational efficiency! The IP200PG is an intercom that can work with wireless mobile IP phones (IP210H, IP200H) as well as fixed and mobile phones. ■ Supports wireless LAN/LTE connections The IP200PG can be connected via wired LAN, but it also allows communication through wireless LAN access points and LTE connections. ■ Easy installation and flexible expandability By utilizing wireless LAN, it can be installed more easily without being limited by location. It can also easily accommodate expansions. ■ Can make calls with fixed and mobile phones By connecting the internal (in-house) LAN to the optical phone via the SIP server SR-8000V, it enables calls with external lines (public lines). ■ Allows calls with IP200PG installed outside or staff on the go (wireless mobile IP phone IP200H) By introducing the RoIP gateway VE-PG4 that connects LAN and LTE lines, you can make internal calls from the intercom IP200PG to an IP200PG installed outside (with SIM) or to staff on the go (IP200H).

[Instructor] Shintaro Fukasawa, President of BM Consulting Co., Ltd. Business Mathematics Educator [Key Lecture Content] There are things we somewhat think about. However, when asked for our opinions, we hesitate to speak up because we dread being questioned with "What is your basis?" This is a growing issue among business professionals. Shintaro Fukasawa, the only advocate of business mathematics in Japan and a business mathematics educator, identifies the inability of modern business people to articulate their thoughts and ideas as a "symptom." He finds commonalities between mathematical thinking and verbalization, and has developed a verbalization framework that anyone can easily practice. This content has been compiled into a book titled "How Can an Idea Become 'My Opinion'? - A Class to Turn Intuition into Logical Opinions" (2023). In this session, we will extract the essence of that book and explain how to create "logical and communicative opinions." You will take home tips that will dramatically change your business communication starting tomorrow.
