Case Study: Coin Parking Challenges At Company C, a coin parking operator, the traditional handset intercom was being handled clumsily by users, leading to frequent malfunctions. Additionally, the handset system required users to get out of their cars to use it, and due to the need for installation inside a box to protect against rain and wind, users had to open the door to operate it, which was particularly problematic during rainy weather as users would get wet. The intrusion of rainwater and deterioration of equipment due to outdoor installation were also serious issues, resulting in skyrocketing maintenance costs. Implementation Effects With the hands-free calling feature of the CIT-200, users can now make inquiries and calls while remaining in their cars, allowing for comfortable use even in the rain without getting wet. The automatic answering function ensures that when a call comes in from the call center, it automatically switches to hands-free mode, enabling communication with users and allowing them to make calls without confusion. The IP65 waterproof standard has completely eliminated malfunctions caused by rainwater intrusion, and the stainless steel housing maintains stable performance even with long-term outdoor use. The I/O functionality allows for automatic reporting of equipment abnormalities in conjunction with the payment machine, and simple troubles can be resolved by users themselves through voice guidance, contributing to a reduction in the burden on the call center.

Case Study: Demand Bus Call Service Challenges In urban G city, the awareness of the demand bus service was low, and improving convenience became urgent. The traditional reservation system was not facilitating usage among the elderly and inbound tourists, and phone reservations took time to specify locations, making real-time responses difficult. Improving access in densely populated areas, around existing bus stops, and near subway stations was also a challenge. Implementation Effects By installing the CIT-200 in densely populated areas within the demand bus operation range, at some bus stops, and near subway stations, users were able to contact the demand bus dispatch center with a single touch whenever needed. Orders from the intercom allowed for location specification, making real-time responses at the call center easier and enabling quick instructions to the optimal vehicle. The IP65 waterproof standard ensured stable operation even when installed outdoors, establishing a system available 24 hours a day.

Issues At the cable car of tourist spot Mount F, the location in a mountainous area made it difficult to lay wired telephone lines, and securing emergency communication means within the vehicles had been a long-standing issue. Additionally, the rapid changes in weather conditions made the durability of the equipment an important requirement. While communication via radio was also considered, there were problems with the complexity of operation and voice quality. Implementation Effects By installing the CIT-200 in each cable car vehicle, passengers can now report directly to the operation management center in case of emergencies. With 4G/LTE support, stable communication is ensured even in mountainous areas. The stainless steel casing and IP65 waterproof standard provide sufficient durability to withstand vehicle vibrations and changes in weather conditions. Hands-free dialing allows for easy operation even in emergencies. Voice guidance provides instructions on how to use the system, alleviating passengers' anxiety. Remote management enables the operation management center to continuously monitor the communication equipment status of all vehicles.
