2. Current Situation in the Development ofTHz Communications • Since 2008, when the IG THz was established, manytechnology and market boundary conditions have improved: • Progress in semiconductortechnology • see e.g. [1] where data rates of 25 Gbit/s over a distance of 10 m have been demonstrated using MMIC technology • WRC 2012 resulted in a stable situation in terms of spectrum activity • Worldwide manyresearchprojects on THzcommunicationshavebeenstarted, • E. g. bigGovernmentfundedprojectsarecurrentlyrunning in Germany, Korea, and Japan • Industryshowssomeinterestnow • Recently the International Wireless Industry Cinsortium (IWPC) has established a Millimeter and sub-Millimeter Wave Nanocell Working Group (http://www.iwpc.org/WorkingGroups.aspx) • CORF spectrum coexistence activity has been initiated with 802.15 Hz IG and MoGIG

3. Headingtowards a Standard on THzCommunications • It‘s time tothinkabouttriggeringtheprocessofgeneratingstandardsforTHz Communications • Presentations on possibleapplications [2],[3],[4] haveclearlyshownthatthevariousapplicationsrequire also solutionswith different technicalcomplexities • As a consequenceinstead of a singlestandardrather a setor a family of individuallyapplicablestandardsmayberequired • A reasonablestartingpointistobeginwithshortrangeapplicationsthatrequireslesscomplexsolutions, e. g. a kioskdownloadingapplication

4. PossibleApplicationsforTHz Communications

5. Pre-requisitstostart a Study Group • To start a study group, a more expanded engagement and committment withappropriatespectrum, industry and industry groups such as the IWPC would be beneficial. • Currentcontributions in the IG THzarefocussing on PHY issues. More participants with expertise on MAC, HetNet, SON, cluster radio management are welcome. • Howtoachieveenhancingawareness on THz Communications andincreaseparticipationfromindustryandexperts on MAC? • The followingmeasurehasbeentaken: • A tutorialhasbeengivenattheJulyplenary

6. What happend after thetutorial in July? • Excerpt form the meeting minutes (IEEE P802.15-12-0417-00-0thz): • Wrap-up of the Tutorial presentation from July 16: The tutorial triggered a discussion on the next steps to be followed by the IG THz and the possible applications on which a Study Group could be spinned-off from the IG THz. An intensive discussion was held on the concept of nano-cells and backhauling of wireless systems . It was decided to set-up relation with the IWPC-MoGIG WG to increase industry participation. • Discussion on a possible contribution to IEEE 802.15 WNG during the November Plenary: The IG THz chair informed the group that during the AC meeting on Wednesday the chair of WG 15 motivated the IG THz to make a presentation to WNG during the November plenary offering the creation of a study group. The preparation will be done via the e-mail reflector and phone conferences if necessary.

7. Whatistheimpact of a Presentationat IEEE 802.15 WNG? • Typically a presentationtothe IEEE 802.15 WNG isgiventopropose a new IG or SG. In order topropose a SG thispresentation will benecessary. • Anotheroption will be just topresent a status of theplans of the IG THztocreate a SG in thenearfuturetothe WNG • In order todecide on a presentationand a possibleformat a IG THzmeeting via Telco will takeplace on Oct. 31, 15 CET

8. QuestionstobediscussedduringtheTelco • Whatarethepossibleapplicationsthatcouldbesubjectto a SG potentiallystartingwithinthenext 12 months? • Whatareongoingactivities in researchandindustry, thatcouldsuppportthework in a SG and a future TG? • What is the optimum time line for these applications to trigger the creation of a SG? • Is the market ready – who will be the industry sponsors to drive the standards activity?

9. DecisionandPreparation of a Presentationto WNG • Atthe end of theTelco a decisionhastobemade on whether a presentation will bemadeto WNG. • Iftheanswerisyes, a decisonisrequired on whatshouldbepresented. • Proposalfortheprocedure: • A smalleditorialteamisset-up, which will prepare a draftofthepresentation via e-mailbeforetheplenarymeeting • The draft will bepresentedtothe IG THz in San Antonio on Tue AM2 • Presentationtothe WNG on Wed PM2
