IWR1443: 75-85 GHz Regulations for non automotive applications

Alvaro Querido
Prodigy 60 points
Part Number: IWR1443

In our company we are developing a sensor for detecting parked cars in parking buildings and on street parking slots.

The sensor will be placed on the floor and have to be detected a car parked over it.

My question is about if it is allowed to use 75-85 GHz band to these application in USA and Europe.

Reading the following regulations it seems that 75-85 GHz is not allowed for our application.

Can you help me for these question?

For Europe:

CEPT/ERC Recommendation 70-03: "Relating to the use of Short Range Devices (SRD)".

ANNEX 6: RADIODETERMINATION APPLICATIONS

75-85 GHz -41.3 dBm/MHz e.i.r.p. outside the enclosed test tank structure

Only for or Industrial Level Probing Radar (LPR) or for Tank Level Probing Radar (TLPR) applications?

ANNEX 13: INFORMATIVE ANNEX COVERING THE APPLICATIONS OPERATING UNDER GENERAL AUTHORISATION REGIME WHICH ARE NOT COVERED BY THE ANNEXES 1 TO 12 OF THIS RECOMMENDATION

77-81 GHz Only for or automotive Short Range Radars?

For USA:

FCC 47 CFR 15.253 – Operation within the bands 46.7-46.9 GHz and 76.0-77.0 GHz.

Operation within the band 76.0–77.0 GHz is restricted to vehicle-mounted field disturbance sensors used as vehicle radar systems and to fixed radar systems used at airport locations for foreign object debris detection on runways and for monitoring aircraft as well as service vehicles on taxiways and other airport vehicle service areas that have no public vehicle access. FCC Report and Order – Radar services in the 76-81 GHz band, ET docket No. 15-26.

FCC 47 CFR 15.256 - Operation of level probing radars within the bands 5.925-7.250 GHz, 24.05-29.00 GHz, and 75-85 GHz.

Operation under this section is limited to level probing radar (LPR) devices.

Part 15 Operations in the 76-77 GHz Band Compliance Requirements

Fixed radar operation is limited to airport locations only

    Hello Alvaro,

    For unlicensed usage, you are correct that there are some restrictions to how this frequency band may be used depending on the region. If you are unable to get the licensing necessary for your application and your region, I believe there may be other options you can explore.

    Looking at FCC 47 CFR 15.256 and ETSI EN 302 729 v2.1.0, I see that there are openings for how a device operating as a LPR (level probing radar) may be positioned. If you have flexibility on installation of the sensor in order to match the downward orientation, mounting height, and field of view specified for an LPR, perhaps your sensor could be positioned as a LPR? You will need to check with the respective regulating bodies to confirm.

    Regards,

    Keegan

    Hi, folks,

    I'd recently searched for the legislation in India, which is although not completely relevant, worth sharing here.

    To quote the notification, named "Use of Very Low Power Radio Frequency Devices or Equipments for Short Range Radar Systems (Exemption from Licensing Requirement) Rules, 2015", "No licence shall be required by any person to establish, maintain, work, possess or deal in any wireless equipment for the purpose of usage of very low power Radio Frequency devices or equipments for short range radar systems in the 76 to 77 GHz frequency band on non-interference, non-protection and shared (non exclusive) basis, with the maximum Effective Radiated Power Limits as specified". The limit is 5 W (37 dBm).

    It does mandate that prior approval of the equipment is necessary, and that "any performance degradation, misinterpretation, or loss of information" in a licensed system arising due to "the effect of unwanted energy due to one or a combination of emissions, radiations or induction" would invite action against interference.
