[Radio Equipment Rental Case] Ski Resort Operations *Interference Countermeasures

[Radio Equipment Rental Case] Ski Resort Operations *Interference Countermeasures

Avoiding interference with a digital simple radio using an amplification type! A case where operations became more comfortable by shortening the antenna.

We would like to introduce a case study of the digital simple radio "SR741 Amplification Type" implemented for customers operating ski resorts. Before the implementation, each team set their own user codes and communicated individually, but they faced issues with overlapping channels and simultaneous transmissions, which hindered smooth communication. By switching to a model that amplifies up to 97 channels, interference was completely eliminated, and the antenna was also changed to a shorter one. This made it easier to carry and store, improving work efficiency and mobility. [Case Overview (Partial)] ■ Challenges - Interference with other teams' radios - Unwillingness to use radios with long antennas ■ Implementation Results - Communication became smoother - Operations became more comfortable due to the shorter antenna *For more details, please download the PDF or feel free to contact us.

[Wireless Equipment Rental Case] Kineko International Film Festival *Expanded Communication Range, Cost Reduction

[Wireless Equipment Rental Case] Kineko International Film Festival *Expanded Communication Range, Cost Reduction

Establish a smooth operational system by using both digital simple radios and IP radios!

We would like to introduce a case where IP radios and digital simple radios were implemented at the Kineko International Film Festival, hosted by the general incorporated association Kineko Film. There were concerns that "communication with digital radios becomes unstable," and they were considering renting IP radios that could cover a wider range. However, they consulted us about the high costs of IP radios, making it difficult to equip all units with them. As a solution, digital radios were used for staff communication inside the venue, while IP radios were implemented for outdoor security and VIP guidance. By changing the type of radio according to the role, we were able to increase the necessary number of units while keeping costs down. 【Case Overview】 ■Challenges - Communication is unstable even over short distances due to building interference. - Radios must be rented within a limited budget. ■Proposal - Expand communication range with IP radios. - Support the film festival with sponsorship discounts. *For more details, please download the PDF or feel free to contact us.
