D t ti f t t H b St t l ti iDocumentation of spectrum use at Hamburg State election in 2008 and 2011. LTE Range was cleared partially already.




Despite production size was only one third in 2011 compared with 2008 use of wireless links increased drastically because ofwith 2008 use of wireless links increased drastically because of cost saving effect. Remark: 2011 was an unplanned election!



Maintaining achieved production qualityMaintaining achieved production quality

C-PMSE Project to maintain reliability of wireless productions in a spectrum with increasing user densityproductions in a spectrum with increasing user density



Increase of user density in the remaining UHF rangeIncrease of user density in the remaining UHF range

Regulators are requested to support the C-PMSE project by assigning frequency ranges instead of fixed frequencies. This will make spectrum use more efficient as also small

spectrum gaps can be used.
