The following section and its Table 18 provide details and discussion of the associated calculations.

11.3.1Details of Exposure Separation Distances Calculations and Power Compliance Margins

Limits and guidelines for RF exposure come from:

US FCC limits for the general population. See the FCC web site at http://www.fcc.gov, and the policies, guidelines, and requirements in Part 1 of Title 47 of the Code of Federal Regulations, as well as the guidelines and suggestions for evaluating compliance in FCC OET Bulletin 65.

Health Canada limits for the general population. See the Health Canada web site at http://www.hc-sc.gc.ca/rpb and Safety Code 6.

ICNIRP (International Commission on Non-Ionizing Radiation Protection) guidelines for the general public. See the ICNIRP web site at http://www.icnirp.de/ and Guidelines for Limiting Exposure to Time-Varying Electric, Magnetic, and Electromagnetic Fields.

The applicable power density exposure limits from the documents referenced above are

10 W/m2 for RF energy in the 5.7/5.8-GHz frequency bands.

Peak power density in the far field of a radio frequency point source is calculated as follows:

S =

P ∀ G

where

S = power density in W/m2

4 # d2

P = RMS transmit power capability of the radio, in W G = total Tx gain as a factor, converted from dB

d= distance from point source, in m

Motorola has long been a key player in the wireless communications market, known for its innovative solutions that cater to various connectivity needs. Among its diverse product range, the Motorola PMP 100 and PTP 200 series stand out as robust solutions for both point-to-multipoint (PMP) and point-to-point (PTP) applications, utilizing advanced modulation technologies such as OFDM (Orthogonal Frequency-Division Multiplexing) and FSK (Frequency Shift Keying).

The Motorola PMP 100 series is designed for wireless broadband access, enabling operators to provide high-speed internet connectivity to rural and underserved areas. Its capability to support multiple users makes it an ideal choice for ISPs looking to deliver last-mile connectivity. The PMP 100 operates in the 2.4 GHz and 5.7 GHz frequency bands, ensuring flexibility and compliance with various regulatory requirements. One of its key features is the use of OFDM technology, which enhances spectral efficiency and minimizes interference, resulting in reliable data transmission even in challenging environments.

On the other hand, the PTP 200 series focuses on point-to-point communication, offering high-capacity backhaul links between two locations. The PTP 200 is optimized for performance in line-of-sight scenarios, featuring advanced antenna options and narrow beam width capabilities. This product also leverages OFDM technology, which provides increased data rates and improved capacity, supporting applications such as video surveillance, voice over IP, and enterprise connectivity.

In addition to the PMP and PTP 200 series, Motorola also offers the PMP 400 and PTP 100, which utilize FSK modulation. The PMP 400 series further advances the capabilities of wireless broadband access, featuring enhanced error correction, allowing for better performance in adverse conditions. This series is particularly well-suited for environments with high noise levels, making it a reliable choice for industrial applications. The PTP 100 series, on the other hand, operates effectively in point-to-point scenarios with lower bandwidth requirements, ensuring cost-effective solutions for dedicated leased line services.

In summary, the Motorola PMP and PTP series represent a comprehensive suite of wireless communication solutions, utilizing advanced modulation technologies like OFDM and FSK to deliver high-speed, reliable connectivity. These products demonstrate Motorola's commitment to innovation, addressing the diverse needs of users ranging from ISPs to enterprise customers, all while ensuring robust performance and ease of deployment in various environments.
