1 Short introduction on PMSE Alain Richer APWPT France WM08 - PMSE Workshop at EuMW2015

2 What is APWPT? The APWPT promotes on an international level the efficient and demand-driven provision and use of production frequencies for professional event productions It also safeguards production frequencies for the users on the long run. APWPT is an independent association, working for the benefit of all professionals who use the radio spectrum. September 7,

3 What does APWPT for French users? APWPT France is involved in any frequency discussions about PMSE with: Administrations ARCEP, ANFR, CSA.. Ministry of Culture and Industry Unions, lobbying groups: SEINEP, FICAM, HD Forum, Synpase, Prodiss End users: TVs, radios, PMSE rental companies September 7,

27 What are the PMSE spectrum requirements? September 7, Systems Solution Channel 07/09/2015

28 September 7, 2015 First, how PMSE works?

29 How PMSE works? PMSE is a wireless system that uses a portion of spectrum There is a transmitter and a receiver, they can be fixed or mobile September 7, 2015

30 How PMSE works? Audio PMSE mainly use the UHF band, sharing spectrum with TV transmission Softwares enables to know which frequency is TV free September 7, 2015

32 How PMSE works Unfortunately, intermodulation happens when several PMSE are used at the same time, in the same place, making frequency allocation quite complex September 7, transmitters

33 How PMSE works September 7, transmitters

34 How PMSE works Frequency calculation is needed to plan frequency of each PMSE

35 How PMSE works? And the more PMSE you use, the more spectrum you need September 7, 2015

36 And PMSE needs are growing Analysis Mason study on PMSE links in TV production September 7,

37 While spectrum is shrinking PMSE spectrum September 7,

38 In conclusion: How PMSE works? Calculating frequency allocation is complex The more PMSE you use, the more spectrum you need The increase of spectrum needs isn t linear with the increase of PMSE links Spectrum will become a scarce ressource for PMSE September 7, 2015

39 Conclusion PMSE are everywhere in our cultural life No production could be made today without them Securing spectrum for PMSE is mandatory, otherwise our culture will be in danger September 7, 2015
