"mcAccess e+" is a service that enhances disaster-resistant MCA radio communication by adding IP radio, thereby doubling the communication capabilities and expanding the coverage area. By utilizing NTT Docomo's LTE and 3G service areas, users can communicate without being aware of which radio they are using, as both can be operated with the same simple controls as MCA radio. Furthermore, by utilizing both the private network of MCA radio and the public network of IP radio, the two networks can complement each other in the event of a failure, allowing for more reliable communication. This service has made it easier to connect in areas where MCA radio previously had limitations, such as tunnels, mountainous regions, and urban canyons, by leveraging the coverage area of IP radio (mcAccess e+). 【Features】 ■ Communication coverage that connects anywhere ■ No additional communication fees, monthly usage fees remain the same ■ Existing radio equipment can be used as is ■ Simply attach a circuit board to the MCA vehicle-mounted unit ■ No changes to the current operating methods *For more details, please refer to the PDF document or feel free to contact us.
