  • for such RSU. Licensees must register each RSU for the smallest communication zone needed (for the DSRC-based intelligent transportation systems application) using one of the following four communication zones: RSU Class Max. Output Power (dBm) 1 Communications Zone A 0 15 meters B 10 100 meters C 20 400 meters D 28.8 1000 meters \1\ The ASTM-DSRC Standard (see § 90.379) limits output power to 28.8 dBm but allows more power to overcome cable losses to the antenna as long as the antenna input power does not exceed 28.8 dBm and the EIRP does not exceed 44.8 dBm. However, specific channels and categories of uses have additional limitations under the ASTM-DSRC Standard. Add § 90.377 to read as follows: § 90.377

  • and Information Exchange Between Roadside and Vehicle Systems-5 GHz Band Dedicated Short Range Communications (DSRC) Medium Access Control (MAC) and Physical Layer (PHY) Specifications. The ASTM standard was adopted in Amendment of the Commission's Rules Regarding Dedicated Short-Range Communication Services in the 5.850-5.925 GHz band (5.9 GHz band), Report and Order, 19 FCC Rcd 2458 (2004). See 47 C.F.R. §§ 90.379, 95.1509. Id. Under a regional planning scheme, the country is divided into regions that have autonomy to develop plans that appropriately meet their different communications needs. To facilitate the shared use of the 4.9 GHz band, each region may (but not must) submit guidelines to be used for sharing the spectrum within their respective regions. See 47 C.F.R. § 90.1211.

  • RSU must accommodate the operation of the early registered RSU, i.e., interference protection rights are date-sensitive, based on the date that the RSU is first registered (see § 90.375 of this part) and the later-registered RSU must modify its operations to resolve the dispute in accordance with paragraph (f). (f) Except as otherwise provided in the ASTM-DSRC Standard (see § 90.379 of this part) for the purposes of paragraph (e), objectionable interference will be considered to exist when the Commission receives a complaint and the difference in signal strength between the earlier-registered RSU and the later-registered RSU (anywhere within the earlier-registered RSU's communication zone) is 18 dB or less (co-channel). Later-registered RSUs causing objectionable interference must correct the interference immediately unless
