The Truth About Cell Towers

May 14th, 2014

Have you ever wondered why we need cell phone towers?
Cell phones being a low watt transmitter/receiver requires a signal repeater within range of the cell phone. The repeaters keeps moving the signal from tower to tower until it reaches the destination cell phone. For the caller to complete the cell phone call it is necessary to have a new type of telephone pole called a cell phone tower (or cell phone antenna) placed at proper intervals along our highways, byways, cities and towns. The number of towers required is directly proportional to the total human population in the area. This information is normally referenced to as “cell tower proliferation” the mathematical principle used to determine the number of cell towers required in a given area. Cell tower proliferation has become a new subject for urban ecologists. In fact, cell phone towers are radio relay stations, due to the short range of the cell phone transmitter/receivers.

cell phone towerA cellular telephone site is where antennas and electronic communications equipment are placed, usually on a radio mast, tower, building or other high place, to create a cell in a cellular network. The elevated structure normally supports antennas, and one or more sets of transmitter/receivers transceivers, digital signal processors, control electronics, a GPS receiver for timing, primary and backup electrical power sources and sheltering.

Many times a cell site is incorrectly called a “cell tower”, even if the cell site antennas are mounted on a building, or other tall structures rather than a tower. In fact, a large majority of cell sites worldwide are located on structures other than towers. In GSM networks, the correct term is Base Transceiver Station and colloquial British English synonyms are “mobile phone mast” or “base station”. The term “base station site” might better reflect the increasing co-location of multiple mobile operators and therefore multiple base stations at a single site. Depending on an operator’s technology, even a site hosting just a single mobile operator may house multiple base stations, each to serve a different air interface technology.

What is the transmitter/receiver range on a cell towers?
In practice, cell sites are grouped in high population areas that would have the most potential users. Cell phone traffic through a single site is limited by the base station’s capacity as there is a limited number of calls or data traffic that a base station can handle at once. This limitation is another factor affecting the spacing of cell mast sites. In suburban areas, masts are commonly spaced 1–2 miles apart and in dense urban areas, masts may be as close as ¼-½ mile apart.

cell phone mastThe maximum range of a mast (where it is not limited by interference with other masts nearby) depends on the same circumstances. Some technologies, such as GSM, normally have a fixed maximum range of 22 miles, which is imposed by technical limitations. CDMA and IDEN have no built-in limit, but the limiting factor is the ability of a low-powered personal cell phone to transmit back to the mast.

As a basic guide, based on how tall the mast is and how flat terrain is, it is possible to send a signal 30 – 45 miles. When the terrain is hilly, the maximum distance can vary from as little as 3 – 5 miles due to encroachment of intermediate objects into the wide center fresnel zone of the signal. Depending on terrain and other circumstances, a GSM Tower can replace between 2 and 50 miles of cabling for fixed wireless networks.

What does GSM, CDMA, iDEN and PCS stand for?
GSM Carriers like T-Mobile and AT&T/Cingular sell their mobile phones locked with their access specifications. These are referred as to as Locked Phones.

concealed cell tower sitesCDMA stands for Code Division Multiple Access. It uses several protocols in second generation (2G) and third generation (3G) wireless communications. CDMA is a form of multiplexing which allows numerous signals to occupy a single transmission channel optimizing the use of available frequencies. This technology uses both the PCS and Cellular signals.

iDEN transmit on the 806 to 866 MHz frequency ranges. This range is used by carriers like Nextel/Sprint, Mike, Southern LINC and Boost. It’s a stand-alone mode.

PCS stands for Personal Communication Service. Sometimes referred to as the Digital Mode, it represent the signals that transmit between frequencies of 1850 to 1992 MHz (megahertz). These frequencies are used by Mobile Phone Standards like CDMA, TDMA and GSM. Most carriers including AT&T, Telus, T-Mobile, Qwest, Verizon Wireless, US Cellular, Alltel and Bell Canada uses PCS network in combination with Cellular.

cell phone tower disguised as a cactusWhat do cell phone towers look like?
A cell phone towers can be a tower or it can be inconspicuous and blend in with the surrounding area. These installations are generally referred to as concealed cell sites or stealth cell sites, where cell towers are often hidden. Some cell sites are camouflage as palm trees, ponderosa pine trees, cactus, large crosses at a church and on buildings and light poles. They also act as radio relay stations, due to the short range of cell phone transmitters/receivers.

Electricity To Your Light Bulb

May 8th, 2014

How many times a day do you flip a light switch on or off? We all know the answer to that… many, many times. Have you ever wondered what happens between point A and point B to get the electricity from its source to the light bulb?

Light BulbFirst, an Electrical Generating Plant must be built to harness the electricity needed for the surrounding area. Once the power plant is built, the electric distribution power lines will move the electricity from the power plant to a building using an aboveground or underground electric power line. When the power line is connected to a building, an electrician will install wires going to every outlet, light fixture and light switch. Finally, you can flip a light switch and a light will turn on.

RP Companies is a full service electrical contractor that specializes in getting electricity from the source to your light bulb. They can complete everything from building an electrical generating plant, to running the distribution power lines, to connecting the power lines to a building. They have the equipment and skilled manpower to provide a project with all aspects of the installation from the underground to all the above ground electrical services.

We are very proud of our outstanding experience and expertise in all aspects of electrical construction and in our ability to complete a project on time and within budget, better serving our Arizona customers.

RP Companies electrical division consists of 3 different types of contractors:

  1. ”Outside” or “line” electrical contractors. These contractors are responsible for high-voltage power transmission and distribution lines. They build and maintain the infrastructure required to transport electricity generated at a power plant through a series of high-voltage lines and substations before it is used to power facilities, buildings and homes.
  2. “Inside” electrical contractors. These contractors provide electricity to any structure within a property’s boundary lines, including outdoor lighting or substations. Under current construction specification guidelines, “inside” electrical contractors can serve as prime contractors for all electrical and cabling design, installation, and maintenance for commercial, institutional, and residential buildings. Projects also include Database Centers/Infrastructure and Pharmaceutical Work.
  3. “Integrated building systems” (IBS) or “Voice/Data/Video” (VDV) electrical contractors. These contractors work primarily with low-voltage installations such as back-up power, climate controls, wireless networks, energy-efficient lighting, telecommunications, fiber optics and security systems. IBS contractors are particularly skilled at integrating these system controls to work together for maximum energy efficiency and building performance.

Electrical Panel InstallationAbove all, RP Companies electrical division ensures that safety is strictly enforced at all our locations and construction sites. We are required to follow the National Electrical Code (NEC) to ensure every system works in a safe manner.
