Tutorial: Microwave Link Planning - Part 1: Basics

Microwave links generally operate between frequencies of 2 and 58 GHz. Initially analogue links were used, but now far superior digital microwave links are used. Digital microwave links have many advantages over the analogue microwave links, some of which are:

·         high tolerance against interference;

·         high tolerance against deep fading;

·         high signal carrying capacity ranging from 2 to 155 Mbps;

·         high frequency range (2–58 GHz);

·         easy, rapid (and hence economical) installations.

As the frequency increases, the length of the link decreases. Due to the high frequency range (2–58GHz), the microwave links can be classified into three main categories:

(a) Long haul

(b) Medium haul

(c) Short haul

Long Haul

The frequency of operation of these links is usually 2–10 GHz. In the best of climatic conditions and

frequency of operation, the distance covered by the links could range from 80 km to 45 km. These links

are affected by multipath fading (explained later).

Frequency band 2 GHz

·         Maximum path length 80 km

·         Multipath fading

·         Antenna diameters up to 370 cm for an antenna gain of 36 dB

·         Both vertical and horizontal polarisations used

Frequency band 7 GHz

·         Maximum path length about 50 km

·         Multipath fading

·         Antenna diameters up to 370 cm for an antenna gain of 46.8 dB

·         Both vertical and horizontal polarisations used

Frequency band 10 GHz

·         Maximum path length about 45 km

·         Multipath fading

·         Antenna diameters 60–120 cm for a gain range of 34–40 dB

·         Both vertical and horizontal polarisations used

Medium and Short Haul

The frequency of operation of these links is usually from 11 GHz to 23 GHz. Depending upon the climatic

conditions and frequency of operation, the hop length can vary between 40 km and 20 km. These links

are also affected by multipath fading and rain fading.

Frequency band 13 GHz

·         Maximum path length about 40 km

·         Multipath fading

·         Antenna diameters 60–120 cm for a gain range of 36.4–42.4 dB

·         Both vertical and horizontal polarisations used

Frequency band 15 GHz

·         Maximum path length about 35 km

·         Multipath fading

·         Antenna diameters 60–120 cm for a gain range of 38–44 dB

·         Both vertical and horizontal polarisations used

Frequency band 18 GHz

·         Maximum path length 20 km

·         Rain and multipath fading

·         Antenna diameters 60–180 cm for a gain range of 39–49 dB

·         Both vertical and horizontal polarisations used

·         Atmospheric attenuation 0.1 dB/km.

·         Attenuation due to rain about 1 dB/km at a rain rate of 20 mm/h

Frequency band 23 GHz

·         Maximum path length about 18 km

·         Rain and multipath fading

·         Antenna diameters 30–120 cm gain for a gain range of 35.5–47.3 dB

·         Both vertical and horizontal polarisations used

·         Atmospheric attenuation 0.1 dB/km

·         Attenuation due to rain about 3 dB/km at a rain rate of 20 mm/h

Before an into explanation is given of various factors that affect the performance of the microwave

links, an attempt will be made to explain the fundamentals of functioning of microwave links.

Microwave-Link-Design ppt

Link : Microwave-Link-Design ppt

This ppt describes the Microwave Link design basics for Transmission Engineers.

Microwave Link Networks

A microwave link is a communications system that uses a beam of radio waves in the microwave frequency range to transmit information between two fixed locations on the earth. They are crucial to many forms of communication and impact a broad range of industries. Broadcasters use microwave links to send programs from the studio to the transmitter location, which might be miles away. Microwave links carry cellular telephone calls between cell sites. Wireless Internet service providers use microwave links to provide their clients with high-speed Internet access without the need for cable connections. Telephone companies transmit calls between switching centers over microwave links, although fairly recently they have been largely supplanted by fiber-optic cables. Companies and government agencies use them to provide communications networks between nearby facilities within an organization, such as a company with several buildings within a city.
One of the reasons microwave links are so adaptable is that they are broadband. That means they can move large amounts of information at high speeds. Another important quality of microwave links is that they require no equipment or facilities between the two terminal points, so installing a microwave link is often faster and less costly than a cable connection. Finally, they can be used almost anywhere, as long as the distance to be spanned is within the operating range of the equipment and there is clear path (that is, no solid obstacles) between the locations. Microwaves are also able to penetrate rain, fog, and snow, which means bad weather doesn’t disrupt transmission.

 A simplified rendering of a microwave link. A microwave link is a communications system that uses a beam of radio waves in the microwave frequency range to transmit information between two fixed locations on the earth.
A simple one-way microwave link includes four major elements: a transmitter, a receiver, transmission lines, and antennas. These basic components exist in every radio communications system, including cellular telephones, two-way radios, wireless networks, and commercial broadcasting. But the technology used in microwave links differs markedly from that used at the lower frequencies (longer wavelengths) in the radio spectrum. Techniques and components that work well at low frequencies are not useable at the higher frequencies (shorter wavelengths) used in microwave links. For example, ordinary wires and cables function poorly as conductors of microwave signals. On the other hand, microwave frequencies allow engineers to take advantage of certain principles that are impractical to apply at lower frequencies. One example is the use of a parabolic or “dish” antenna to focus a microwave radio beam. Such antennas can be designed to operate at much lower frequencies, but they would be too large to be economical for most purposes.
In a microwave link the transmitter produces a microwave signal that carries the information to be communicated. That information—the input—can be anything capable of being sent by electronic means, such as a telephone call, television or radio programs, text, moving or still images, web pages, or a combination of those media.
The transmitter has two fundamental jobs: generating microwave energy at the required frequency and power level, and modulating it with the input signal so that it conveys meaningful information. Modulation is accomplished by varying some characteristic of the energy in response to the transmitter’s input. Flashing a light to transmit a message in Morse Code is an example of modulation. The differing lengths of the flashes (the dots and dashes), and the intervals of darkness between them, convey the information—in this case a text message.
The second integral part of a microwave link is a transmission line. This line carries the signal from the transmitter to the antenna and, at the receiving end of the link, from the antenna to the receiver. In electrical engineering, a transmission line is anything that conducts current from one point to another. Lamp cord, power lines, telephone wires and speaker cable are common transmission lines. But at microwave frequencies, those media excessively weaken the signal. In their place, engineers use coaxial cables and, especially, hollow pipes called waveguides.
The third part of the microwave system is the antennas. On the transmitting end, the antenna emits the microwave signal from the transmission line into free space. “Free space” is the electrical engineer’s term for the emptiness or void between the transmitting and receiving antennas. It is not the same thing as “the atmosphere,” because air is not necessary for any type of radio transmission (which is why radio works in the vacuum of outer space). At the receiver site, an antenna pointed toward the transmitting station collects the signal energy and feeds it into the transmission line for processing by the receiver.
Antennas used in microwave links are highly directional, which means they tightly focus the transmitted energy, and receive energy mainly from one specific direction. This contrasts with antennas used in many other communications systems, such as broadcasting. By directing the transmitter’s energy where it's needed—toward the receiver—and by concentrating the received signal, this characteristic of microwave antennas allows communication over long distances using small amounts of power.
Between the link’s antennas lies another vital element of the microwave link—the path taken by the signal through the earth’s atmosphere. A clear path is critical to the microwave link’s success. Since microwaves travel in essentially straight lines, man-made obstacles (including possible future construction) that might block the signal must either be overcome by tall antenna structures or avoided altogether. Natural obstacles also exist. Flat terrain can create undesirable reflections, precipitation can absorb or scatter some of the microwave energy, and the emergence of foliage in the spring can weaken a marginally strong signal, which had been adequate when the trees were bare in the winter. Engineers must take all the existing and potential problems into account when designing a microwave link.
At the end of the link is the final component, the receiver. Here, information from the microwave signal is extracted and made available in its original form. To accomplish this, the receiver must demodulate the signal to separate the information from the microwave energy that carries it. The receiver must be capable of detecting very small amounts of microwave energy, because the signal loses much of its strength on its journey.
This entire process takes place at close to the speed of light, so transmission is virtually instantaneous even across long distances. With all of their advantages, microwave links are certain to be important building blocks of the world’s communications infrastructure for years to come.

1+1 Protected Microwave Radio Link Block Diagram

Link Block Diagram

This diagram is from an NEC 500 series microwave link system (circa 1983) and shows one path. The "return direction" block is the reverse of that detailed in the main diagram.

Regulatory and Licensing

Each country has a varying requirement for the licensing of microwave radio links. In most cases this license only addresses the transmitter, but in the same instance, it offers regulatory protection to any inteference that may affect the microwave receiver.
License costs are usually linked with the size of the spectrum occupied by the transmitter signal - and are often directly influenced by some of the spectrum lease costs realized by the local regulator, eg FCC, ACMA, PTT's etc.
A safety aspect of microwave radio EMR radiation is also defined by standards and guidelines, and often human exposure 'exclusion' zones exist around the front of microwave dish antennas, horns and dielectric antennas. Personnel safety must also be considered around open waveguide ends and waveguide switches with unterminated ports. Refer to other material at the GHN on EMR Safety.

Frequency Planning

Sample extract of micrwave band frequency planning

In the older FDM microwave radio link systems, only a single pair of frequencies were allocate to the whole link network, with an alternating polarisation isolation arrangement from more distant stations in the network. This meant that at a single microwave repeater station, the link transmitters operate on the same frequency, but with antennas pointed in different directions, and with opposite antenna polarisation.

Link Planning

The design and construction of a microwave radio link network is based on a numner of factors. These include:

• Distance between microwave radio terminals
• Terrain properties, eg bodies of water, cliffs, forests, snow
• Frequency of operation, often governed by licensing costs, frequency availability, planned distances and even suspectibility to rain fading.
• Fading, dispersion and multipath distortion.
• Size of antennas, feedline properties, need for towers and masts.
• Council and community development permissions governing visual intrusions.
• Cost of equipment and cost benefit analysis including equipment maintenance.

WiMAX Network Survey:Guideline

In a series on how to plan a city-wide wireless WiMAX network.

Companies or cities that have decided to or are considering building and operating wireless broadband networks have several important issues to consider in terms of how to proceed. Once demographic, competitive, financial, commercial and/or residential market analysis is complete, the operator must conduct a thorough engineering site survey of the area to be served. Once that is completed, the data learned and gathered during the survey will aid in the development of a preliminary network design.

The initial spectrum for WiMAX in the US is unlicensed spectrum in the 5GHz range. Given that this spectrum is 'open to the public', it has inherent interference issues and risks which need to be studied carefully. A quality site survey can provide an invaluable insight into current or potential interference issues. As will be discussed in the WiMAX network design document, there are many effective ways to minimize interference in unlicensed WiMAX networks both from a site selection and equipment selection perspective.

The In-field Site Survey
A site survey is required, in short, because the operator wants to minimize the "unknowns" regarding the network prior to construction and the operator wants to develop a vision of "how" the network will work once it is built.

A site survey provides the necessary information for a complete WiMAX network blueprint, or design, which is needed in order to minimize hurdles and costly mistakes as the network is being built-out. A quality site survey will be precise to the last frequency, spectrum analysis, connector, nut & bolt.

There are many tools, online databases and mapping resources available that were developed specifically for wireless broadband technologies and applications. Much of the pre-survey and post-survey planning can be done with reasonable accuracy hundreds of miles away. There are "predictable" formulas that can be applied to the variables on any network rollout. But unlike copper or fiber networks, there are variables in a wireless network with which trained and experienced network engineers and administrators are quite often unfamiliar.
These wireless network variables include:

• The impact of the fresnel zone on signal propagation
• The difference between passive gain and powered amplification, and when use of each is appropriate
• The orchestration of sector, space, frequency and polar diversification(s)
• The use of a Front to Back ratio
• How many channels are available for use and where are potential interferers located
• The +/- 3dB rule and how it influences the link budget
• How and why "application" must drive the hardware
• Lastly, what to do when the light just won't come on

All these engineering variables apply to site-specific situations, scenarios and topology. Most represent only a fraction of the "issues" that will be encountered, and must be addressed during the deployment of a wireless network.
Quality wireless network engineers will have years of in-the-field experience recognizing and solving these issues. As wireless network planning is concerned, more information equals higher engineering and performance accuracy, which minimizes the total cost of network deployment. The operator's goal is to design a quality network with no surprises at the end.
Some elements of a standard RF site survey:

• A quality site survey starts several days before the site visit by documenting tower and other attachment sites available. Once these sites have been researched and documented, they should be geo-coded on a topological map to assist in selection of best candidates once on the ground. This prep work and mapping work will also reduce the time on the ground, thus reducing the overall site survey costs.

Geo-code and photo-document the target locations (mounting points, cable runs, electrical closets, etc.) This allows the engineering firm to recommend what components are needed in the network, not what is generally or historically needed.

• Perform and document multi-spectrum (900MHz, 2.4GHz, 4.9 GHz, 5.3 and 5.8GHz) activity by utilizing a spectrum analysis, as appropriate to the application. This allows engineers to work around potential frequency issues before the fact, not onsite during installation with tower rigger crews charging by the hour as they wait for the solution.
• Spectrum analysis can be accomplished with varying degrees of precision. A scan of a frequency can be done in 10 minutes (with minimal collection of data) or in 10 hours (with considerably more data collection). It's even recommended to sweep both horizontal and vertical polarities, something most firms do not do.
• Detect and document existing wireless networks including SSID and frequency info.
• Verify available mounting locations/altitudes which aids in an accurate site parts list.
• Initial verification and planning for available A/C power helping eliminate onsite power issues.
• Verify visual LOS to target feeder tower's (potential tower bearings having already been determined pre-survey). This is a redundancy check against engineering software for potential manmade obstructions not represented in the software calculations.
• Verify available space on recommended towers (expedites the lease process by getting it right the first time) and the type of tower utilized. This information is provided to the tower owners during the lease process, and to the tower riggers and/or equipment vendor to insure that the right kind of mounting brackets are ready before installation.
• Deploy and evaluate a temporary test link to verify RF functionality for less than certain solutions. For all the recent science and technology, nothing works as dependably as installing and testing a system first.
• A detailed view of the operator's current or planned backhaul location and documentation of potential hand-off requirements.
• Identify many more location-specific issues that must be addressed and resolved in the final deployment plan.
• Identify the general tree foliage environment and document the estimated losses needed to apply to the coverage propagation software. Inputting reasonable losses for foliage will provide a more accurate picture of the overall coverage capability.

ITU-T Recommendations and Practical Applications in PDH/SDH Networks

ITU-T Recommendations and Practical Applications in PDH/SDH Networks pdf


Telecommunications networks are not built from technologies that are individually specified by each
service provider. If they were, imagine how hard it would be to connect from one service provider to
the next! The logical solution is to have a universal organization (or organizations) specifying transmission
methods that are universally applicable to all service providers. One of these bodies is the
International Telecommunication Union 􀀀 Telecommunication Standardization Sector (ITU-T)
formally known as CCITT. The ITU-T is responsible for studying technical, operating and tariff questions
and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide
basis.

Many telecommunication networks use network elements that are specified by ITU-T Recommendations.
The Advanced Network Tester (ANT-20) recognizes these Recommendations and carries out measurements
to qualify them. This note will directly quote Recommendations from ITU-T and then apply them
to practical applications performed on the ANT-20.
