Radiation Warnings
Microwave Radio Radiation Warning
Under normal operating conditions, N2­limits for human exposure to radio frequency (RF) fields adopted by the Federal Communica­tions Commission (FCC). All Wireless, Inc. microwave radio equipment is designed so that under normal working conditions, microwave radiation directly from the radio is negligible when compared with the permissible limit of continuous daily exposure recommended in the United States by ANSI/IEEE C95.1-1991 (R1997), Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz.

radio equipment complies with the
Microwave signal levels that give rise to hazardous radiation levels can exist within transmitter power amplifiers, associated RF multiplexers, and antenna systems.
Never look into the open end of a Waveguide as eyes are particularly vulnerable to radiation. Do not disconnect RF coaxial connectors, open microwave units, or break down any
microwave screening while the radio equipment is operating.
vi
Microwave Antenna Radiation Warning
Designed for point-to-point operation, an N2-
X Ethernet Extender
microwave radio system will use directional antennas to transmit and receive microwave signals. These directional anten­nas are usually circular or rectangular in shape, are generally located outdoors, and are usually mounted on a tower or mast.
Referencing OET Bulletin 65 (Edition 97-01, August 1997) from the Federal Communication Commission’s Office of Engineering & Technology, limits for maximum permissible exposure (MPE) to microwave signals have been adopted by the FCC for both Occupational/Controlled environments and General Population/Uncontrolled environments. These limits are 5.0 mW/ cm2 and 1.0 mW/cm2, respectively, with averaging times of six-minutes and thirty-minutes, respectively.
The closer you are to the front center-point of a microwave antenna, the greater the power density of its transmitted microwave signal. Unless you are very close, however, microwave exposure levels will fall far below the MPE limits. To determine how close to a microwave antenna you can be and still remain below the MPE limits noted above, “worst case” predictions of the field strength and power density levels in the vicinity of an N2-
X Ethernet Extender
TM
microwave antenna can be made from the following calculations. The equation is generally accurate in the far-field of an antenna, and will over-predict power density in the near-field (i.e. close to the antenna).
S = PG/4πR
2
where: S = power density (in mW/cm2)
P = power input to the antenna (mW) G = power gain of the antenna in the direction of interest relative to an isotropic
radiator
R = distance to the center of radiation of the antenna (cm)
Note that G, the power gain factor, is usually expressed in logarithmic terms (i.e., dB), and must be converted using the following equation:
G = 10
dB/10
For example, a logarithmic power gain of 24 dB is equal to a numeric gain of 251.19. Assuming (1) maximum output power from the N2-
(2) no signal loss in the cable connecting the N2-

(+3.5 dBm [2.238 mW]),
to the antenna, and (3) the use of a 27 dBi gain parabolic antenna, the 5.0 mW/cm2 and 1.0 mW/cm2 MPE power density limits would be reached at distances of approximately 4.22 cm and 9.44 cm, respectively.
Wireless, Inc. fully supports the FCC’s adopted MPE limits, and recommends that personnel maintain appropriate distances from the front of all directional microwave antennas. Should you have questions about N2-

1.0 General Overview
1.1 N2-ACCESS Series Product Family
All N2-X Ethernet Extender radios are members of the N2-ACCESS Series radio product family. The N2- ACCESS Series is designed to provide an economical wireless solution for local access telecommunication requirements.
The N2-ACCESS Series radio product family consists of several product offerings, to include both the N2-ACCESS Link. This manual addresses, in detail, the operation of the N2-X Ethernet Extender. For detailed information on other N2-X Ethernet Extender radios or other members of the N2-ACCESS Series, please refer to the appropriate Operation Manual(s).
1.2 Introduction to the N2-X Ethernet Extender
The N2-X Ethernet Extender series of radios are designed for operation in two of the Unlicensed National Infrastructure at frequencies of 5,250 - 5,350 MHz or 5,725 - 5,825 MHz.
Each N2-X Ethernet Extender is comprised of a pole mounted RF/antenna unit. Each link is powered by means of a AC wall transformer (optional DC powering available) located with the indoor terminal unit. The system has a data transmission capacity of 16 Mb/s. Refer to the N2­X Ethernet Extender data sheets for information relating to product offerings and specifications.

1.3 Regulatory Information
In January 1997, the FCC made available 300 MHz of spectrum for Unlicensed National Information Infrastructure (U-NII) devices. The FCC believes that the creation of the U-NII band will stimulate the development of new unlicensed digital products which will provide efficient and less expensive solutions for local access applications.
The U-NII band is divided into three sub bands at 5.15 - 5.25, 5.25 - 5.35 and 5.725 - 5.825 GHz. The first band is strictly allocated for indoor use and is consistent with the European High Performance Local Area Network (HIPERLAN). The second and third bands are intended for high speed digital local access products for “campus” and “short haul” microwave applications.

N2-X Ethernet Extender Installation and Operation Manual
2.0 N2-X Ethernet Extender Product Profile
2.1 General Overview
The N2-X Ethernet Extender series of microwave radio products provides digital capacities for 16 Mb/s data rates for short-haul applications up to 10 km. The radio terminal operates in the newly allocated Unlicensed National Information Infrastructure (U-NII) spectrum with a revolu­tionary Split Modulation system architecture that provides full duplex operation in the 5.3/5.7 GHz U-NII frequency bands.
The N2-X Ethernet Extender series provides the unique advantage of a very robust digital transmission scheme.
Split Modulation uses two separate 100 MHz bands within the U-NII frequency spectrum. Within these bands, the N2-X Ethernet Extender series operates in one of many independent channels providing for frequency reuse and network flexibility, ideal for dense network applications.
Synthesized RF channel selection is field configurable, as are the power output options for the selection of antenna sizes. Frequency coordination and installation guidelines are provided in the appendix section of this manual.
Complying with all aspects of FCC Rules Subpart 15.401-15.407, the transmission character­istics of the N2-X Ethernet Extender series are ideally suited to meet the peak power spectral density requirements of the U-NII 5.250 - 5.350 and 5.725 - 5.825 GHz bands.
Note: From this point on in this Operations Manual, unless specified otherwise, the term N2-
X Ethernet Extender refers to the 5.3/5.7 GHz N2-X Ethernet Extender radio.
The N2-X Ethernet Extender as been designed for complete front access to all interfaces, controls and displays. Information in this manual will familiarize you with all of these items. Figure 2.1 illustrates two (2) N2-X Ethernet Extender terminals in a point-to-point configuration.
