Preguntas más frecuentes

Q1: How does Point-to-Multipoint (P2MP) work, and how many receivers can connect to one transmitter?

UN: Our COFDM video transmission system operates in a broadcast mode, similar to a TV broadcasting station. One transmitter can send the same wireless signal to multiple receivers simultaneously.

As long as the receivers are within the effective signal coverage area and configured to the same frequency and parameters, they can all receive the signal at the same time.
En teoría, there is no fixed limit to the number of receivers; por lo tanto, the maximum number cannot be precisely specified and depends on practical deployment conditions.

Q2: Is the IVCAN COFDM system compatible with third-party or existing transmitters and receivers?

UN: Compatibility depends on multiple technical factors, incluida la frecuencia, ancho de banda, modulación, and transmission protocol. Without detailed specifications or actual testing, compatibility with third-party or existing equipment cannot be confirmed. To ensure accurate results, compatibility testing is required before we can provide a definitive answer.

Customers are welcome to share detailed technical information about their existing devices so we can evaluate potential compatibility or recommend appropriate testing solutions.
