Vehicle-mounted general-purpose radio transceiver / Licensed station 'TCM-D244SR/GSR'

Vehicle-mounted general-purpose radio transceiver / Licensed station 'TCM-D244SR/GSR'

Compact and affordable wireless device.

In analog business radios, there were issues with not being able to hear the other person's voice clearly due to noise, and it became difficult to hear as the distance increased. The TCM-D144/D244/D344 series adopts a highly rated 4-value FSK digital method. Compared to conventional analog radios, it allows for clear voice communication with less noise even at greater distances. Additionally, due to dual-mode compatibility (with some exceptions), it can flexibly accommodate a gradual transition to digital based on budget. By integrating with GPS location management systems, it supports the efficiency of various operations such as transportation, logistics, and delivery. 【Features】 ○ Digital communication without white noise ○ Clear and easily understandable digital communication with distant parties ○ High sound quality due to the adoption of DSP, with minimized delay ○ Adjustable sound quality according to the usage environment ○ Secret communication function to prevent third parties from overhearing calls For more details, please contact us or download the catalog.

[Case Study of Radio Equipment Introduction] Pharmaceutical Manufacturing Related *Digitalization & Communication Efficiency in Hazardous Areas

[Case Study of Radio Equipment Introduction] Pharmaceutical Manufacturing Related *Digitalization & Communication Efficiency in Hazardous Areas

Efficient communication within explosion-proof areas! A case study utilizing existing wireless devices effectively.

We would like to introduce a case study of the wireless devices we handle for businesses in the pharmaceutical manufacturing industry. They faced challenges such as wanting to digitize their wireless communication and having two devices: an explosion-proof device and a registered station, and wanting to communicate with both using a single device. Therefore, we proposed the digital-compatible explosion-proof wireless device "NX-330EXCT" for the explosion-proof area, and "TCP-D751" for the office and non-explosion-proof work area. As a result, the clarity of communication was achieved through digitization, enabling communication between the explosion-proof and non-explosion-proof areas. [Case Overview] ■ Industry: Pharmaceutical Manufacturing ■ Manufacturer: JVC Kenwood Corporation ■ Models Introduced: Intrinsically Safe Explosion-Proof Wireless Device "NX-330EXCT" Digital Simple Business Wireless Device "TCP-D751" ■ Number of Units Introduced: 15 units *For more details, please refer to the PDF document or feel free to contact us.

[Case Study of Radio Equipment] Muto Gakuen Yuai Kindergarten - Real-time Information Sharing

[Case Study of Radio Equipment] Muto Gakuen Yuai Kindergarten - Real-time Information Sharing

The audio is clear without any noise! It is also possible to communicate disaster prevention information over a wide area.

We would like to introduce a case study of the wireless devices handled by our company that were implemented at Muto Gakuen Yuyai Kindergarten. Due to the rich natural environment, communication was hindered by the mountains. In a situation where analog radios were discontinued and a transition to digital radios was unavoidable, careful consideration of communication methods led to the "EVOLVE" product. After implementation, it has been fully utilized for information sharing and communication. With clear sound quality, location information can be easily utilized and shared, making time management for pick-ups and drop-offs easy and providing peace of mind and convenience for parents. [Case Overview] ■ User: Muto Gakuen Yuyai Kindergarten ■ Industry: Kindergarten ■ Model Introduced: 4 units of WAVEPTX wireless device EVOLVE ■ Usage: Operations at the kindergarten and on the school bus *For more details, please refer to the PDF document or feel free to contact us.
