Suggested steps for MWL setup

The process of establishing a reliable microwave system should include the following steps. Step 1: A preliminary engineering study for feasibility and budgetary proposal purposes. Step 2: A site survey to determine equipment installation requirements. Step 3: A field path survey to verify station coordinates, path topology, and any obstructions.

Step 4: Final system engineering, utilizing verified data from the site and path survey, to address critical path clearances, reflection analysis, link analysis, and determination of required antenna heights above ground level. Step 5: Revision of the initial budgetary proposal into a firm, fixed-price quotation for the turnkey system.

1.1. The Fundamental Elements of “Line-ofSight” Microwave Radio Systems This section covers the basic technical elements that provide a foundation for understanding line of-sight radio frequency systems. The topics include:

• Frequency • Fresnel zones • Wavelength • Phase Relationships • Free-space Loss • Multi-path Reflections • Precipitation Loss • Atmospheric Refraction • Antenna Gain • Earth Bulge • Antenna Beam-width

Frecuency

Since microwave frequencies have short wavelengths, they generally require a “line-of-sight” (LOS) propagation path. They also need clearance for what is referred to as “the 1st Fresnel zone,” whose boundaries vary with the frequency and wavelength of the specific system.

Microwave Frecuency varies in between 300 GHz - 300 MHz

Wavelength Electromagnetic waves propagate at the speed of light (in freespace or a vacuum), or 300,000,000 meters per second. As a result, wavelength in meters can be calculated by dividing the number 300 by the frequency in MHz. The density of the transmission medium produces changes in radio wavelengths; similar to the way it affects speed. One 2400 MHz wavelength in free-space = 11811/2400 = 4.921 inches One 2400 MHz wavelength in normal atmosphere = 11811/2400 x .9997 = 4.920 inches One 2400 MHz wavelength in LMR 400 coax = 11811/2400 x .85 = 4.183 inches These seemingly small differences can be far more important than they seem at first, since radio link systems have path lengths that are measured in miles or kms. Over these distances, the minute differences in each wavelength become very significant, because of the vast number of wavelengths required to cover even a single mile

Free-space Loss Free space attenuation (or loss) increases as frequency goes up, for a given unit of distance. This occurs because higher frequencies have shorter wavelengths, and to cover a given distance; they must complete many more cycles than lower frequency signals, which have longer wavelength. During each cycle (wavelength) the signals propagate, some of their energy is “spent.”

Where: FSL= Decibels F= Frecuency in Mhz D= Distance betwen end points…

32.44 varies depeding on the constant of system losses and the working units for F and D.

Free-space Loss (cont) • FSL = 92.4 + 20 log d + 20 log f – d = distance in km d f = frequency in GHz GTX Power Level

Precipitation Loss Frequency and wavelength are also affected by precipitation, which comes in many forms. The detrimental effects of precipitation vary according to the physical properties of its form, as well as its wavelength relationship to that of the particular frequency involved. Basically, when an object’s physical properties approach ¼ wavelength of a particular frequency, they become highly reflective at that frequency. Raindrops can easily attain a dimension of 1/8 inch or more, effectively becoming multiple reflectors (or more accurately stated, deflectors) in the path of a 23-GHz signal, while having much less impact on a 5.8 GHz signal. However, water droplets of smaller size, including fog, can become a major consideration for millimeter wave like over 25Ghz systems.

Precipitation Loss: Rain & Fog Fading • Generally, different frequency band has different loss.

– less than 10 GHz, its fading caused by rain and fog is not serious.

– over 10 GHz, relay distance is limited by fading caused by rains. – over 20GHz, the relay distance is only about several kilometers for the rain & fog fading. Page19

Creating “RF line-of-sight” for a microwave path requires more clearance over path obstructions than is required to establish a visual “line-of-sight.” The extra clearance is needed to establish an unobstructed propagation path boundary for the transmitted signal, based on its wavelength.

The Fresnel Zones

Phase and Its Relationships

Since atmospherically propagated radio signals can take many paths between one point and another, as in the case of a multi-path reflected signal, it is possible for them to arrive at the destination in different phase states. As long as the signals travel a direct path between the antennas, they will arrive fairly closely in phase with one another, however different paths may end up with wave cancelling each other.

Atmospheric Refraction In radio engineering, atmospheric refraction is also referred to as “the K factor,” which describes the type and amount of refraction. For example: A K factor of 1 describes a condition where there is no refraction of the signal, and it propagates in a straight line. A K factor of less than 1 describes a condition where the refracted signal path deviates from a straight line, and it arcs in the direction opposite the earth curvature. A K factor greater than 1 describes a condition where the refracted signal path deviates from a straight line, and it arcs in the same direction as the earth curvature.

Atmospheric Refraction: K Factor Fading • A equivalent radius: Re=KR (R is the real radius of earth). • the value of K is depend on the local meteorological phenomena

Atmospheric Refraction – Atmosphere absorption mainly affect the microwave whose frequency is over 12 GHz. – Refraction, reflection, dispersion in the troposphere. – Scattering and absorption loss caused by rain, fog and snow. It mainly affect the microwave whose

frequency is over 10 GHz.

Multi-Path Propagation and Fading • The receiving paths includes direct path and other reflection paths. • Multi-path fading is caused by the signals interference from

different propagation paths

Physical Earth Bulge Line-of-sight radio system engineering must deal with the effects of earth curvature, or “Earth Bulge” as it is sometimes called. Physical Earth Bulge reflects earth curvature only and does not take into account the effects of atmospheric refraction. For purposes of line-of-sight radio link design, we must always combine Physical Earth Bulge with the effects of atmospheric refraction, or K. When these two parameters are combined, a modified earth bulge profile results, which is known as “Effective Earth Bulge.”

Antenna Beam-width Since antenna gain results from redirecting available radiated energy in a given direction, the higher the antenna gain of an antenna in its forward direction, the lower its gain in other directions. That’s why larger antennas with higher gain are more directional. Consequently, they are often used to solve interference problems when the interference source may be located off-azimuth from the affected system path.

Half power angle

Half power angle (3 dB beam width) From the main lobe deviates to both sides, the points where the power decrease half are half power point. The angle between the two half power points is half power angle.

Approximate calculation formula is:

Antenna Specifications (cont.) • Cross polarization discrimination (XPD) – The suppressive intensity of power received from expected polarization (Po) to the other polarization (Px). It should more than 30db. Formula is:

Link feasibility

Path Profile

A Path profile is a graphic representation of the path traveled by the radio waves between the to ends of a link. The Path Profile determines the location and height of the antenna at each end of the link. All of the previously mentionated concepts are meant so you can decicie a working frecuency or set of frecuency, Antifading methods to be applied and the required equipment to be used.

Basic Recommendations • Use higher frequency bands for shorter hops and lower frequency bands for longer hops • Avoid lower frequency bands in urban areas • Use star and hub configurations for smaller networks and ring configuration for larger networks • In areas with heavy precipitation , if possible, use frequency bands below 10 GHz. • Use protected systems (1+1) for all important and/or high-capacity links • Leave enough spare capacity for future expansion of the system
