CURRENT STATUS OFCEPT THE MANDATE REPORTCEPT THE MANDATE REPORT

An Early version of the Interim Report is realized. C i t t ibl ith t dditi l iti ti t h iCoexistence not possible without additional proven mitigation technics.Chapter 5.2 Possible Mitigation Technics needs to be rewritten. Initial coexistence proposals from the WiFi community are received.

One country promote “shared the burden”One country promote shared the burden , as basic principle of equal usage. The work has been split between:

CPG PTD (Conference Preparatory Group)CPG PTD (Conference Preparatory Group), technical contribution related to radio location and radio navigation.SE (Spectrum Engineering), technical contribution investigations related to the band above 5750 MHzFM (Frequency Management), collect the results and realize ECC/CEPT report. (answer to the EU comm.) A correspondence group to manage the work.


EUROPEAN FREQUENCY REGULATION

Even more important then Spectrum sharing at this time.Proposed Frequency Mask To be accepted!

Change?

Current Technology cannot support the current Frequency Mask

Liaison Statement by the ECC related to ETSI-SRdoc TR 103 083Endorsement by the ECC, WGFM results in review of the spectrum according to ECC decision and recommendation (08)01according to ECC decision and recommendation (08)01Action status: WGFM allocated coexistence investigation tasks to WGSE.


EUROPEAN FREQUENCY REGULATION

REQUIRED ACTIONS BY STAKEHOLDERS

All European Deployment Project need to request for OFFICAL use of theAll European Deployment Project need to request for OFFICAL use of the ITS channels at there Country specific Frequency regulators to support the SPECTRUM MASK change acceptance.

Concrete contribution by relevant stakeholders such as Car OEMs, y ,Infrastructure OEMs and Road Operators required to influence the Mitigation Technics chapter investigations of the CEPT SE24 report.

Coordinate with other Functional interest groups like BFWA, WIA, FSS and DAGCDAGC

Concrete contribution by Umbrella organizations, such as Amsterdam Group, CEDR, VDA, FIA, ACEA, Asecap and C2C-CC leading to political pressure needed to ensure the ITS bands in Spectrum sharing and feasiblepressure needed to ensure the ITS bands in Spectrum sharing and feasible Frequency Mask.

Almost 2 billion chips shipped in 2013. Need more spectrum for Wi-Fi

IEEE 802.11 WIRELESS LAN WORKING GROUPRegulatory Standing Committee TIGER TEAMChair: Jim Lansford (CSR) “Tasked is to propose candidate coexistence method(s) for sharing 5.9 GHz band”Approach:

WiFi i d t t ith h( ) d l• WiFi industry to come with approach(es) and proposals.• Car industry to provide information and feedback. Monitor output.Extensive work by Car Industrie expected later phases, e.g. testing.

OpportunitiesWi-Fi suggestion Detect and Avoid – same access technology

ThreatsInterference to low latency C-ITS – safety servicesHidden node problem with different power levelsToll collection 5795-5815 MHz for Europe

Car Industry inputs to Tiger Team:Car Industry inputs to Tiger Team:Harmful Interference presented at TT Nov1, 2013. DSRC Packet Error Ratio vs. Received signal strength experimental data (CAMP)


• Wi-Fi devices listen for DSRC

• When car appears, Wi-Fi detects DSRC

• DSRC detected Wi-Fi NOT ok to operate (minimum 10 second delay

CISCO PROPOSAL

• No DSRC Wi-Fi ok to operate• Continues to listen while WLAN operates

R ti TTReaction TT (No formal position)Unofficial concerns expressed include: Too “polite” to DSRC. Would eliminate effective use of band by Wi-Fi in too many places; Requires 802.11ac silicon changes – delay and $

Some see Cisco might have an advantage


• Move DSRC safety from

QUALCOMM PROPOSAL• Move DSRC safety from

Ch. 172 to upper band (non-overlap portion)

• Cancel highest 20 MHz Wi Fi (Ch 181)Wi-Fi (Ch. 181)

• DSRC use 20 MHz channels in overlap portion instead of 10 MHz

Reaction TTNot consistent with Part 15 (FCC unlicensed device) sharing rules. Places burden primarily on ( ) g p yDSRC to change, Incorrect premise that all “critical” DSRC traffic can fit in upper band. Incorrect that 20 MHz is better than 10 MHz..Profoundly disruptive to DSRC deployment: research and testing needed. Placing BSMs spectrally close to Public Safety raises cross-channel interference concerns. Sharing in lower band forecloses DSRC innovationUS-specific, will not work with EU spectrum allocation. Outside scope of FCC NPRM 13-49All of above concerns are documented in comments to FCC

Drafting and IEEE approvals will take about one month

N t StNext Steps:Asking for more proposals, and more details on existing proposals. Use cases to consider for simulation and testing. Simulation and testing resultsAttempt to reach consensus on one or more approaches to recommend for fieldAttempt to reach consensus on one or more approaches to recommend for field testing and FCC consideration. New contributions have been slow in coming
