Question 9. What Is Rf Engineering? Answer : Radio-frequency engineering is a part of electrical engineering that deals with devices that are designed to operate in the radio frequency spectrum.
These devices operate within the range of about 3 kHz up to GHz. RF engineering is incorporated into almost everything that transmits or receives a radio wave, which includes, but is not limited to, mobile phones, radios, Wi-Fi, and two-way radios. Question Answer : RF engineering is a highly specialized field falling typically in one of two areas:. Answer : RF energy is one form of electromagnetic energy that is a component of the electromagnetic spectrum, which covers microwaves, visible light and X-rays, as well as many more kinds of energy emissions.
RF energy, sometimes called "RF emissions," "RF waves" or "RF fields," is generated when a source current, such as a transmitter, is fed to an antenna. This current excites electrons within the antenna and the energy moves outward in the form of an electromagnetic wave.
Answer : Probably the most important use for RF energy is in providing radio communication services to the public, industry and government. Radio and television broadcasting, cell phones, radio communications for emergency services, weather radar and satellite communications are examples of important applications.
Non-communication uses of RF energy include industrial heating and microwave ovens. Some consumer uses of radio communication include baby monitors, rf engineer interview questions answers pdf download, garage door openers, cordless telephones, WI-FI, remote key-less car entry devices and various medical devices, just to name a few.
As well, certain non-radio devices, including computers and other digital devices, also emit RF energy. Answer : At radio communication and broadcasting installations, you will generally find radio transmitters and receivers, transmission lines and antennas, as well as their supporting structures. Radiocommunication and broadcasting transmitters are electronic devices that generate RF signals which carry the information intended for receivers.
The signals are transmitted by antennas and then picked up by receivers via receive antennaswhich then extract the information carried, be it a cell phone conversation or a television program. This document has been adopted by many organizations across Canada and is referred to in several regulations.
Industry Canada has adopted this guideline for the purpose of protecting the general public. Answer : Exposure to RF energy at levels below the regulatory limits is considered to be safe. These limits are based on the lowest exposure level at which the potential harmful effects to humans could occur.
Safety factors are then incorporated to arrive at recommended exposure levels for protection of the general public. Answer : Health Canada's guideline document and most rf engineer interview questions answers pdf download RF exposure standards specify "time-averaged" maximum exposure limits. The purpose is to "smooth out" the short-term highs and lows of the exposure intensity to arrive at an "average" with which to compare to the limit.
The averaging time is the time period over which exposure is averaged. The averaging time should not be interpreted as the maximum allowable exposure time.
As per Health guideline document, it is permissible to exceed the recommended exposure limits for short periods of time as long as the average exposure over the averaging time 0.
Answer : A biological effect occurs when a change can be measured in a biological system after an introduction of some type of stimulus e. RF energy. The observation of a biological effect, in and of itself, does not necessarily suggest the rf engineer interview questions answers pdf download of a health effect.
Answer : A biological effect only becomes a health effect when it causes detectable impairment of health. According to the World Health Organization, health is "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity. Answer : The biological effects from laboratory studies reported in scientific peer-reviewed literature include those related to changes in temperature, blood brain barrier, melatonin, calcium efflux, DNA damage and gene expression.
However, not all these biological effects have been established or are considered to be health effects. For example, blood brain barrier and melatonin effects have not been consistently replicated. Studies on DNA strand breaks have also failed numerous independent attempts at confirmation and calcium efflux changes are considered to be more of a biological response than an adverse health effect.
Several laboratory studies have looked into whether RF energy can initiate and promote cancer. The overwhelming majority of these studies have found no evidence that RF energy damages DNA or that it is likely to act as an initiator or a promoter of carcinogenesis.
Answer : An "established effect" is one that, based upon peer-reviewed scientific reports, is demonstrated to be reproducible in more than one laboratoryconsistent within rf engineer interview questions answers pdf download same laboratory and across other laboratories and causal due to the exposure agent. Answer : An epidemiological study is the investigation of the occurrence and causes of health effects in human populations.
Answer : There have been numerous epidemiological studies on RF exposure and its impacts on human health. The majority of these studies have failed to find any association between such exposure and any adverse heath effects. Answer : Signal modulation is a process whereby certain characteristics of a radio wave are varied with transmitted information voice, pictures and data.
Answer : Different signal modulations in both analogue e. AM and FM and digital numeric formats have been used rf engineer interview questions answers pdf download radio communication. Although most radio technologies originally used analogue signals, modern wireless telecommunications use digital transmissions. Detailed scientific reviews conducted so far have not revealed any hazard specific to different RF modulations.
Answer : EHS is a term used to describe a variety of non-specific symptoms, such as headache, fatigue, nausea, ringing in the ears, digestive disorders, skin redness and burning sensations, which some individuals attribute to electromagnetic field EMF exposure. At levels normally encountered in our daily lives, EMFs are unperceived by our senses. Although EHS symptoms are real, numerous scientific studies have failed to demonstrate that they are associated with EMF exposure. In studies where human subjects including EHS sufferers were intentionally exposed to EMFs, most individuals were unable to detect whether EMFs were present, or showed symptoms that did not correlate with their actual exposure condition.
The causes of EHS symptoms are unclear. There are suggestions that they might arise from environmental factors unrelated to EMFs. Answer : The limits specified in Health RF guideline document were established from the results of hundreds of studies over the past several decades where rf engineer interview questions answers pdf download effects of RF energy on biological organisms were examined. These limits are similar to other national and international standards that are based on established effects.
All recognized standard-setting bodies use the same scientific data and a similar general approach to develop safety guidelines. Differences in interpreting the biological effects under certain exposure conditions sometimes result in small differences in rf engineer interview questions answers pdf download exposure limits. These small differences will not affect a person's health. Canada's exposure limits are among the most stringent guidelines that are based on established effects.
Answer : The precautionary principle is a public policy approach for risk management of possible, but unproven, adverse health effects. The extent of the precautionary principle ranges from monitoring scientific developments and providing information to stronger measures, such as lowering exposures. The increasing public concern over the RF health issue has led to demands for industry and regulatory authorities to apply the precautionary principle to the use of cell phones and the proposed construction of new broadcasting and radiocommunication installations.
The application of the precautionary principle should rf engineer interview questions answers pdf download proportional to the level of risk and its associated uncertainty, rf engineer interview questions answers pdf download, the severity of the outcome and the level of societal benefit.
In the context of RF energy from broadcasting and radiocommunication installations and apparatus, health risks from exposure below the limits specified in Health Canada's guideline document have not been established. Therefore, if precautionary measures are introduced to reduce exposure levels, it is recommended that they be made voluntary. Answer : RF field measurements take into consideration local terrain and structures and indicate actual levels, whereas calculation is a prediction that includes certain assumptions, erring on the side of caution.
Industry Canada requires proponents and operators of radiocommunication and broadcasting installations to take RF field measurements to demonstrate compliance where it is suspected that the regulatory limits might be exceeded. Answer : Yes multiple antenna towers and broadcast antennas safe. Answer : Radio communication, including the technical aspects of broadcasting, falls under the responsibility of the Minister of Industry, who has the power to establish standards, rules, policies and procedures regarding radio communication.
