The Concept of Cellular Base Station Antennas

Cellular antenna concepts: Cellular antennas are a familiar feature in nearly every corner of the world. In many cases, these are cellular networks that bring new connectivity where it had never before been possible – and these connections depend on cellular base station antennas. In cellular base stations, there are two basic antenna types currently […]

How To Increase Antenna Signal Strength Through Design

Vertical and horizontal antenna radiation patterns: All antennas, regardless of polarization, have three-dimensional radiation patterns. If the pattern is extended in all directions equally, the resulting shape would be a sphere, with the antenna at its center. The polarization of the antenna determines which portion of that sphere represents an antenna’s actual pattern. Slicing the […]

The Quest For A Stronger Signal Strength With Base Station Antennas

Getting the signal across: Today, the quest for a stronger antenna signal strength – or for some, any signal strength at all – has become a routine part of our daily lives. We’re always searching for a way to get more “bars” on our cell phones or faster Wi-Fi connections on our computers. Whether you’re […]

Remote Electrical Tilt Antennas

Setting and troubleshooting remote electrical tilt antennas: Of the many ways you can improve performance from a cell site’s antennas, a particularly effective method is beam-tilt. It involves physically tilting the orientation of the antennas below the horizon, placing its greatest gain – its operational power – where it’s needed most. Efficiently changing the orientation […]

Cell Site Development & Construction: Choosing Coaxial Cable and Connectors

Choosing coaxial cable and connectors: Efficient cell site operation relies on the precise pairing of components. Certain cable types are designed to work with certain antennas, those cables must interface with their systems via connectors built for certain frequencies and power levels (figure 1). An out-of-specification component or an improper installation of the correct component […]

Cell Site Development and Construction

Cell Site Development and Construction: Building a new cell site raises some of the same questions as building a new house, such as deciding what materials to use, who to entrust with the construction, and how to get the best results for your money. Of course, these problems are magnified when applied to cell site […]

RF Communications: Then and Now

RF systems, then and now: Wireless RF communications systems have been in commercial use since the 1940s. Some of the earliest implementations included community repeaters, paging systems, point-to-point links and specialized mobile radio (trunked) systems. More recent innovations and uses of the RF spectrum include cellular radio networks, which originated in the 1980s and now […]

How To Achieve A Small Cell Solution In LTE Networks

How do small cells fit into a LTE network? Like sector splitting, small cell solutions allow operators to layer on new capacity without physically building new macro infrastructure to meet growing demand. As a result, they efficiently provide coverage to high concentrations of user traffic. What are the different kinds of small cells? Technically, anything […]

The Microwave Backhaul Challenges Specific To LTE Networks

Challenges With Microwave Backhaul in LTE Networks: LTE networks exist to serve the skyrocketing demand for data. As a result, the backhaul needed to move massive amounts of data requires a solution of greater capacity and performance than for previous generations of mobile networks. What is backhaul? Backhaul is the aggregation of a cell site’s […]

A Guide To Antenna Selection And Deployment For LTE

Why does selecting the right antenna matter so much in LTE? In order to provide LTE-level capacity, antennas must support higher modulation schemes than were required by 2G and 3G networks. Modulation compresses data, improving throughput but increasing interference sensitivity. LTE also requires antennas with optimal RF containment to prevent sector overlap, because it does […]
