HDwireless RFiber system

The importance of wireless cameras for broadcasting and events is perpetually increasing. The requirements regarding efficiency of wireless camera systems that cover vast areas are on the rise, especially for live sports events. At planning complex wireless transmissions not only radio links are used. Optimal sites for RF-antennas are calculated and connected with fiberglass cross-links, depending on the requirements.

With this technology signals from various antenna sites can be linked via fiberglass inside one mobile production unit – such as the HDwireless RF1 or a mobile editing. The software „HDwireless System Overview“ offers effective observation of long or linked wireless transmissions. This way each RFiber-unit on site can be regulated transparently and intuitively. This software enables the operator not only to control the RFiber units but also the demodulators and decoders within the fiberglass network. For the user, various fiber-connection-systems like Lemo, Neutrik, LC, SC or customer-specific solutions are available.

 

System components like RFiber are used for the implementation. With the in-house developed HDwireless product RFiber, for example, high or intermediate frequency signal can be transported without loss for several kilometers before they will be demodulated by receivers and forwarded to decoders. In this case, either a high-frequency signal between 1,9 and  4GHz, or alternatively an intermediate-frequency from a downconverter between 70 – 860 MHz is converted to glass fiber.
HDwireless System Overview
RFiber comes in robust in- and outdoor units, and was developed for professional broadcasting. Every unit is equipped with a display, indicating the relevant parameters like temperature, fiber-status and voltage. In the Lemo version, the outdoor units (ODU) are supplied with power over a maximum distance of 2,500 meters. For the use of other fiber-connections, the outdoor-units (ODU) can be powered directly using a 12VDC-power supply or rechargeable batteries.
Every outdoor-unit can be connected to two separate antennas. At the indoor-unit, the transferrred signals are available on BNC-connectors for further distribution. Optionally, camera-control-transmitters, data-radios or GPS-modules for exact localization of the antenna-array can be attached to the ODUs. Within the dry-hire rental HDwireless offers all components for high frequency wireless and fiberglass transmission.
