    The spectrum that makes up the wireless spectrum is called the wireless spectrum. This Spectrum can be considered both air and land-based, as it can be found in both buildings and outdoors.

    The Fcc refers to this as the “air-ground” or A-G mobile radio frequency (MHz) system. As you can guess, this includes frequencies between 2.4 and 2.6 GHz, or the range of a mobile phone signal.

    The FCC has defined what property owners must have to legally use the wireless spectrum for landline phones on their website under the heading “Propertyowner Requirements”.

    Definition of radio waves

    the wireless spectrum, as defined by the fcc, spans between which two frequencies?

    Radio waves are electromagnetic waves. These can be static electricity-free or heavy electrical currents-inducing.

    Electromagnetic waves can travel through space and time, making them a universal transmission method. They are used in broadcasting, cellular phone signals, radar signals, etc.

    Different radio frequencies exist based on how close they come to the designated electromagnetic wave frequency. The designated frequency is called the middle ground between black and white electricity standards. The lower end of this is referred to as red and the upper end is referred to as blue.

    These middle ground frequencies are what defines which two bands of unlicensed communications spectrum the Fcc classifies as “Wireless Spectrum” and “Other Spectrum.

    Ultra high frequency (UHF)

    the wireless spectrum, as defined by the fcc, spans between which two frequencies?

    The UHF frequency range spans from 500 to 750 MHz. This is the same frequency range as the cellular phone and cable TV channels, but in a different format.

    These channels are located in the lower portion of the DVB-T signal. This signal is found inside television signals, including those for television and digital TV.

    The UHF channel grid is present in all shapes and sizes. It can be a single-digit number or a five-digit number, it can be left or right-justified, and it can be embedded or non-embedded.

    The only difference is whether or not it is preceded or followed by an A or an H.

    High frequency (HF)

    the wireless spectrum, as defined by the fcc, spans between which two frequencies?

    The frequencies above the radio band are called the high frequency bands. These include the microwave, infrared, and ultraviolet frequencies.

    Most of these frequencies are reserved for military and scientific applications, making them expensiveresources. These applications include radar, television broadcast signals, and signal transmission devices like phones and televisions.

    The majority of homes do not have a signal in one of these bands! This is because our environment trick us into thinking there is something broadcasting a signal when thereis not.

    These bands aren’t completely absent of technology either- many early electronic devices used the radio spectrum! Some used in this article use the term wireless spectrum to describe their usage range, showing both how rare this technology is today as well as its historical popularity.

    Medium frequency (MF)

    the wireless spectrum, as defined by the fcc, spans between which two frequencies?

    The medium frequency (MF) spectrum was originally designated as the UHF television broadcast frequencies in the early 2000s. At the time, consumers had TVs that emitted a high-definition signal called UHD or ultra-high-definition.

    These consumer televisions produced a medium-frequency signal called HDTV or high-definition television. This spectrum was once used to produce classic television signals such as those found in the 1950s and 1960s.

    These signals were referred to as standard definition because they did not feature any higher quality video than standard television broadcast signals. These signals were typically used in restaurants and clubs to display more crisply displayed video content, especially during gaming events.

    This medium frequency (MF) spectrum is typically not used for broadcasting content now, though some local TV stations use it for historical purposes.

    Low frequency (LF)

    the wireless spectrum, as defined by the fcc, spans between which two frequencies?

    The LF spectrum includes radio frequencies below 30 Hertz (30 kHz). These are the radio frequencies that determine what songs and messages can be communicated through television and internet broadcasts.

    LF frequencies include those in the middle of the range from 30 to 30,000 Hz (cycles per second). This range of frequencies includes those in the broadcast television and premium television channels! Most people don’t know that there are these high-quality channels because they are not placed very prominently on a TV set.

    The reason these middle-range frequencies aren’t used more often is because they cost more to operate than the higher Hz frequencies. It costs more to make and program a broadcast on a middle-range frequency than a higher one does!

    Aside from being too expensive to use in our modern society, another problem with these low-frequency waves is health concerns. Because they are so small, no one has been able to fully research their effects on health, but studies have shown minor health issues such as headaches or fatigue when using them.

    What are the different types of spectrum?

    the wireless spectrum, as defined by the fcc, spans between which two frequencies?

    The Fcc describes two types of spectrum: licensed and unlicensed. Licensed spectrum is occupied by a single company and is marked off in squares on a map. Unlicensed spectrum is not marked as a space for licensed frequencies, but it can be used for radio transmissions.

    Unlicensed spectrum ranges in frequency from channelized TV channels to mobile phone towers! Many of the times, unlicensed spectrum is used for radios, leading to issues like cord-cutting and lost subscriptions.

    Most of the time, unlicensed Spectrum does not reach into our home territory! But when it does, then problems arise!

    More people realize that this space exists so they try to use it instead of cable or satellite TV because it is free.

    ) Why is the wireless spectrum so crowded?

    the wireless spectrum, as defined by the fcc, spans between which two frequencies?

    There are a number of reasons that the wireless spectrum is so crowded. One of the biggest reasons is that large companies control much of the infrastructure that supports cell phones and wireless broadband.

    The largest mobile phone providers in the United States are subsidiaries and joint ventures of large Internet and cable company owners. This means that these companies have a lot of power to market their services, as they can use their financial strength to persuade Congress to approve new spectrum licenses.

    Another reason why there is so much spectrum is that there is so much it can be used on. Because new licenses can range from 100 MHz to 1 GHz in size, having enough spectrum for all the newly assigned licenses has been a challenge.

    Who regulates the wireless spectrum?

    the wireless spectrum, as defined by the fcc, spans between which two frequencies?

    The FCC Regulates the Wireless Spectrum

    The Federal Communications Commission (FCC or Commission) regulates the airwaves that are called the wireless spectrum. The wireless spectrum is divided into two parts: a Lower Mobile Radio Frequency (LMR) band and a Higher Mobile Radio Frequency (HMF) band.

    The LMR band includes channels 6 through 9, but includes no more than 3 channels in each configuration. For example, channels 6 and 7 are combined into one channel called 1, which is then split into 2 channels called 1.1 and 1.2, respectively.

    The HMF band includes channels 20 through 39, with some configurations having more than 37 channels.
