FIVE MAIN TYPES OF TOWERS

Cell phone communication towers are an essential part of providing Cell phone communication service. A collection of Cell phone communication towers creates a cellular network, which provides coverage to a large region. Cell phone communication companies are frequently looking to build new Cell phone communication towers in order to strengthen their service in a particular area, and these companies are often willing to rent already built Cell phone communication towers on private property. Thus, if you have the means, building a Cell phone communication tower on your property can be very profitable

Different types of cell phones towers

The Monopole Tower is a single tube tower. It typically stands between 100-200 ft. with antennas mounted on the exterior of the tower. Its primary use is telephony.

The Lattice Tower A lattice tower is often called a self-supporting tower. Lattice towers are generally made out of steel and offer the most stability of the cell phone tower types. A lattice tower can be found in either a square or a triangular shape. The lattice towers offer the most flexibility of all of the cell tower types.

The Guyed Tower is basically a straight rod supported by wires that attach to the ground as support. It’s cheapest to construct, especially at heights of 300 ft and beyond. Some guyed towers reach as high as 2,000 ft. Typical uses are: telephony, radio, television, and paging.

Concealed Towers  Concealed Tower are a particular brand of concealed towers. Another manufacture of concealed towers in Larson Camouflage. Concealed towers are deployed to satisfy zoning regulations, and can range in size to accommodate their surroundings. They are more expensive than other types of towers because they require additional material to create a “concealed appearance,” yet at the same time, they provide less capacity to tenants than other towers do. Below is one of the more interesting concealed towers, located at a church in California.

Broadcast Towers provide mounting space for FM radio, AM radio, and Television (TV) antennas. Their antennas are massive, weighing anywhere from 1,000 pounds to 15 tons depending upon the type of service they provide and the coverage they are purposed to deploy. Most broadcast towers are guyed towers with three or more guy wires attached to grounded anchors. Broadcast towers can take up a great deal of ground space – up to 300 acres, which is why they are typically found in rural areas or on mountaintops where natural elevation provides the best means of transmitting signals.

Cell phone communication towers are structures built on specific parcels of land that are designed to accommodate wireless tenants. Wireless tenants utilize cell towers to deploy various technologies to a subscriber base, such as telephony, mobile data, television and radio. Cell towers are typically built by tower companies or wireless carriers.

An Antenna Array is a platform where tenants mount antennas, which signal transmission and reception to mobile devices within a specific area. The number of antennas (typically between 3-18) is based on several factors, including the number of tenants (wireless carriers); the type (voice or data) and volume of transmission; the technology being used (eg: CDMA, GSM, LTE, WiMAX) and the frequency of spectrum (in MgH) utilized.

The Microwave Dish is a large round antenna, which is used for a specific type of transmission, and also commonly used for backhaul.

cell tower ground lease
The Ground Space is the area that wireless carriers lease from property owners, upon which they build cell towers, cell sites and place shelters, generators and additional equipment.

Base Transmitter Station
The Base Transmitter Station or BTS is a shelter or enclosed area used to house and protect communications, radio and network equipment.

The Generator is powered by gas or diesel and used as emergency back-up to keep cell sites operational during power outages.

Utilities are also necessary for the operation of cell sites. Wireless carriers will run lines or cables to the site to complement their specific technology.

Building a Cell phone communication tower

Building a Cell phone communication tower requires money, permission and outside workers.
Step1
Obtain good land. The most important aspect of being able to build a Cell phone communication tower is to have good land to build it on. Ideal land for the construction of a new Cell phone communication tower includes being far away from other towers, being in a densely populated area that uses cell phones and being in an area that your local government has zoned for the building of a Cell phone communication tower.

Step2
Find an interested Cell phone communication company. Building a Cell phone communication tower can be very expensive (upward of $318,000). Thus, you don’t want to build one unless you know a Cell phone communication company is interested in leasing your tower. Many local governments won’t even allow you to build a Cell phone communication tower unless you have a letter of intent from an interested Cell phone communication company.

Step3
Contract workers. Needless to say, the construction of a Cell phone communication tower is not an activity that can be done by a single person. While there are several different types of towers, the construction workers will build a tower that includes four basic parts: the tower itself, equipment, antennas and utilities.

We receive many inquiries from property owners who confuse the actual tower with antennas that are placed on rooftops. These antennas are more accurately described as cell “sites”, but the real definition of a cell site is: an area within a wireless service providers network that can be serviced by an antenna array. Thus, there can be multiple cell sites (and multiple tenants) on any one given tower (or rooftop). This article will help clarify the difference between the types of towers and the equipment that is placed on and used for cell site transmissions.

What’s the difference between Tubular Towers and Angular tower

What’s the difference between Tubular Towers and Angular tower

 What’s the difference between Tubular Towers and Angular tower ?

1513214189626

The question of whether to use angular or tubular towers is always at the background of every project, the answer is not straight forward, because each type of tower is suitable to certain applications. As apparent from Mer Telecom’s line of telecom towers, we have incorporated both designs in order to supply cost effective towers to a wide variety of applications.

What’s the Tubular Steel Poles

Tubular steel poles are another of the major types of transmission towers. They are made up of hollow steel poles. Tubular steel poles can be manufactured as one large piece, or as several small pieces which fit together.

What’s the Lattice Steel Tower?

Lattice steel towers are made up of many different steel structural components connected together with bolts or welded. Many different types of lattice steel towers exist. These towers are also called self-supporting transmission towers or free-standing towers, due to their ability to support themselves. These towers are not always made of steel; they can also be made of aluminum or galvanized steel.

: Angular VS Tubular Comparison Table

 

Angular Towers

Tubular Towers
Members are available in several steel grades Better weight/strength ratio
Members are available in many sizes Lower wind drag brings to smaller foundations
Material is usually less expensive More efficient cross section for buckling
Available in 90° sections, can be bent to 60° Less eccentric connections brings to smaller elements
Fabrication is less expensive (no welding) Large variety of sizes
Transportation is more efficient (better weight/volume ratio) Transportation is more expensive
All surfaces are exposed to the galvanization process All tubes must be open ended to ensure complete galvanizing on the inside

Angular sections are preferred for most small towers with relatively light loads, mainly because of the wide range of sizes, simple connections and low manufacturing cost.

For bigger towers and heavier loads, tubular sections are becoming more useful and more economical. While the costs do differ from one telecom towers manufacturer to another, it is true that the cost of manufacturing is significantly higher, mainly because of the welding process, but the weight to strength ratio is much lower than in angular sections.

Kehang steel tower company’s products mainly include communication towers, radio towers, monopole, portable signal tower, Angular and Tubular Towers,camouflage tree tower, Telecommunication Tower, Communication Tower, Microwave Tower, Angle Steel Tower, Steel Pole,steel tower lightning protection and grounding devices, electricity power transmission tower and substation infrastructure etc.

First, the advantages and disadvantages of the angle steel tower

The quadrangular angle steel tower is the most commonly used communication tower structure in China. Its advantages are simple connection structure, convenient processing and installation, easy to control quality, and a solid and thick appearance. Due to the smaller slewing radius of the angle steel, in order to control the slenderness ratio of the rod members, and to reduce the free length of the components, a sub-divisional web rod is set up and many auxiliary rods are added, thus increasing the amount of steel used. In addition, the angle coefficient of the angle steel is larger, and the auxiliary member without force increases the windage area of ​​the tower, resulting in a much larger wind bending moment than the steel pipe tower, and the amount of steel used and the basic construction cost are also relatively large.

Second, the angle tower facade selection

The communication angle tower is a cantilever structure, and the rational selection of the tower body facade is parabolic. It is generally more economical when the ratio of the bottom opening (side width) to the height is from 1/5 to 1/6. When the communication angle tower of 50 to 60 meters in height has a bottom side width of 8 to 10 meters, the overall construction cost is relatively low. If the space at the bottom of the tower is reduced due to site constraints, the material for the webbing is shortened and the weight is reduced, but the basic cost is increased. The overall cost may increase. Therefore, in determining the selection of structural facades, when the tower height is determined, the bottom span of the tower can be selected according to the geological conditions and the size of the wind load. When the foundation is poor and the wind pressure is large, the tower bottom span is large and can be reduced. Tower’s overall investment.

The width of the top side of the quadrangular angle tower is generally 600mm, so that the platform for installing the communication antenna will not be displaced too much. If the outer ladder is used, the upper side of the angle tower should be no less than 1000mm.

The shape of the angle tower should also be considered as beautiful as possible. Parabolic modeling requires that the slope of the tower be gradually reduced from the bottom to the top. The curve of the entire tower should not have a large abrupt change, and the slope of the diagonal bar is more reasonable than 45′.

Third, the angle tower tower structure

The angle steel tower pylons generally use single angle steel, the upper force adopts Q235 steel in the small town, and the lower force can use Q345 steel, which is selected according to the height of the communication angle tower and the size of the wind pressure. Theoretically, the column length to thin ratio A ≤ 150, the actual choice is best not to exceed 120, because the slenderness ratio of large plants, the stability of the compression column A is small, the increase in the column stress is not cost-effective. The use of sub-divisional web arrangements can reduce the slenderness ratio of the column.
