WHERE CAN WISYCOM BE FOUND?

Spectrum evolution

WHY ULTRAWIDE BANDWIDTH? The reason is simple: Digital Dividend, 4G and in future 5G are progressively reducing the UHF spectrum available for radio-microphones. It’s not a secret that the 700-800MHz band will be totally gone in the close future and we do expect the 5G to be reduced too in EU as well as it is, for example in USA. This make the market asking for more flexible device and here is where Wisycom steps in.

Working smoothly in those present/future spectrum scenarios, is therefore one essential feature for the newest wireless systems: Main technical parameters involved are related to: ü Bandwidth agility (capability of wide-tuning) ü Spectral efficiency (width of my modulation or minimum channel spacing) ü Spectral clean (capability of generate low intermodulation)

NARROWBAND TRANSMISSION

100 kHz 200 kHz

Wisycom offers different options to be as most efficient as possible RF wise, optimizing it’s carriers by reducing the band occupation and being able of fitting a huge number of transmitters in a smaller amount of space. This new narrowband technology allow the user to have only 200KHz of separation between the two carriers, compared to the 400Khz that we’re used to with wide band analogue and 500 to 600KHz for the average digital system. All this, moreover, is done without loosing any sensitive audio quality as the audio is incredibly linear up to 17KHz.

Spectrum evolution

• On the right figure, the spectrum of 3 couples of microphones

using different modulation.

• Level is the minimum level that system allows to work (i.e. you

RF squelch). System robusteness: “Narrowband-dsp-FM” is at least 15 dB more robust than Digital” and 3 dB more robust than legacy FM. 15 dBuV could be a good example of noise on a TV channel after the 700 MHz shitch off: à Under this condition coverage will be heavily reduced and 15 dB of extra margin will be very important for medium to big installations (i.e. theater, studios).

Filter area under the noise level is the actual internal system interference. Wider bandwidth brings to an higher internal noise. Digital Mic have about 1/2 dB more noise than an FM system. standard FM has about 3/4 dB more noise than Narrowband DSP FM. Average digital system needs at least 13 dB S/N,

MRK980

MRK980 TRUE DIVERSITY DUAL RECEIVER

Wisycom MRK980 is a true diversity, ultra-wideband dual channel receiver. With its 1090MHz of band switching, it ensures the users an exceptional band flexibility, combined with a superb selectivity and inter-modulation immunity, for best operating performances

• f the wireless microphone systems. MRK980 also features an internal DSP processor,

Wisycom famous Multicompanding system, new Dante compatibility and a completely and renewed user interface, which make this system easy and quick to setup.

MAIN FEATURES

• Two channels True Diversity receiver (full DSP processed)
• Up to 1090 MHz bandwidth from 170MHz to 1160Mhz
• Push to talk (PTT) incorporated
• Multicompander system
• Dante machine syncronized
• Wideband and Narrowband DSP-FM operation
• Expansion boards slot for RFoF and monitor functions

MRK980 – Expansion Board EXP1

EXP1 is an optional accessory which can be mounted on MRK980 dual channel receiver. This expansion board enables three different features:

• Zoning signal distribution
• External monitoring

cascade

• Two GP OUT

This new board transform the MRK980 into a customizable and incredibly versatile receiver, with several unique options. The external audio monitoring function allows several MRK980 to be connected in cascade through the “Monitor I/O”, in

• rder

to enable an additional auxiliary audio output common to all receivers. Activated by a front panel button, it allows an additional audio monitoring interface to be obtained, in addition to the standard headphones output: this auxiliary slot consists of two mini XLR 5 pins: 1 IN, 1 OUT.

MRK980 – Expansion Board EXP1

The Zoning (or N Diversity) signal distribution function consists of connecting different MRK980 receiver audio

• utputs in cascade. These receivers are all tuned to the same frequencies and connected through 3 pin XLR
• connectors. This type of configuration results in having the audio signal shared between the MRKs, so it’s analyzed

by the receivers and the one with the best quality signal will be picked to send the audio out. In the example below we have three different zones (3x A / B antennas) connected to three distinct MRK980s. The receivers, in turn, are connected to each other through the expansion board auxiliary audio outputs. In the “master” receiver Main audio output (Unit 3) we will have the best audio signal resulting from the comparison

These two wideband receiving optical modules allow the MRK980 to receive RF over fiber signals from a source like Wisycom MFL and open the door to a completely new way of receiving antennas signals from further areas. This implementation massively enlarge the MRK980 reception possibilities by allowing to replace the regular coax cable with optical patches which have an average loss of 0.4dB per Km

MAT288 WITH LFA ANTENNAS

This slide shows how the MAT288 can turn a complex antenna system into a very reliable and controlled one. With the MAT288 we can control and monitor the RF conditions of 8 different Diversity areas, by checking the RF levels and turning ON and OFF the un needed locations to avoid the risk of non wanted interferences. Through the MAT we can also control and monitor the receiving antennas LFA (or BFA booster). This allow to have a full RF control on your computer from where you can easily modify every single device parameter and keep them monitored through the entire show. The MAT288 has three different configuration: 8:1, 8:4 (example below) and 2x4:2 which make this device very versatile.

RF over FIbre

The optical fiber that enables light transmission is actually an assembly of 3 subcomponents: The core is made of glass (or, more accurately, silica) and it is the light-carrying part. The surrounding cladding provides the difference in refractive index that allows total internal reflection of light through the core. The coating, which is usually one or more layers of polymer, protects the core and cladding from from environmental and mechanical damages that might affect their optical or physical properties. The coating has no optical properties affecting the propagation of light within the fiber. RF OVER FIBER SYSTEM

RF over Fibre

Multimode fiber has light traveling in the core in many rays, called modes. The core may have an overall diameter of 9 µm for singlemode or 50 µm or 62.5 µm for multimode transmission. The cladding has an overall diameter of 125 µm. Combining the core and cladding diameters is the source of

• ptical fiber descriptors,

such as 50/125 µm or 62.5/125 µm The core diameter and its refractive index characteristics determine the light propagation path or paths within the fiber’s core. Singlemode fiber has a much smaller core, only about 9 microns, so that the light travels in only one ray (mode.)

Example: TPC (Switzerland)

In this example all the receiving antennas are combined and controlled by the MAT288 located inside the central control room. Four of the remote areas (Studios D, E, F and G) are linked to the control room through the RF over fiber system. Studios A, B and C are connected through standard coax cable. MFL system allows you through the MUX/DEMUX system to use one single fiber patch to both receive and transmit signals from local to remote areas. Remote active antennas are all filtered thanks to the new Wisycom booster BFA which incorporates three different filtering modes.
