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 […]

Outdoor Cell Site Construction Best Practices & Considerations

How do cell site construction practices relate to LTE? LTE performance depends on having the right infrastructure in the right places. While many LTE deployments involve adding technology to existing macro cell sites alongside 2G and 3G infrastructure, there are still opportunities to construct entirely new sites in areas with growing demand and population density. […]

Implementing Distributed Antenna Systems (DAS) In LTE Networks

How do Distributed Antenna Systems (DAS) fit in LTE Networks? Often called the original small cell technology, distributed antenna systems (DAS) allow operators to offload wireless traffic from a particularly user-dense environment from the macro network. Distributed antenna systems (DAS) are also an effective way of bringing reliable, high-quality LTE data service to hard-to-cover areas, […]

What is Fiber To The Antenna (FTTA), & How Does It Figure In LTE Networks?

FTTA Implementation For LTE Networks Fiber to the antenna (FTTA) wireless site architecture is characterized by remote radio units (RRUs) and other components located at the top of the tower rather than at the traditional base location. This configuration allows for enhanced energy efficiency, increased bandwidth and improved flexibility—all essential ingredients for a successful LTE […]

How To Avoid PIM Interference Within LTE Networks

Why is PIM a LTE challenge? As LTE networks are overlaid on legacy 2G and 3G network infrastructure, interference becomes a real challenge — particularly passive intermodulation, or PIM. PIM interference has been a known issue for as long as RF communications have involved more than one component. However, LTE is particularly sensitive to its effects. […]

Co-Siting Solutions For Combining Existing Technologies With LTE Deployments

What Is Co-Siting? Co-siting, also called co-location, is the practice of sharing site resources between base station radios. On a practical level this generally means multiple technologies, radios and/or channel elements sharing space on a single tower. In some cases, it even includes multiple operators sharing the same radio equipment and RF path, separating services […]

Interference Mitigation Techniques in LTE Networks

Why Is Interference A LTE Challenge? Distinct from the broadband disruption of noise, interference is a discrete issue more prevalent in urban and suburban areas where pattern-controlled antennas are the norm. Because LTE performance is so significantly impacted by any kind of interference, it’s important that the network’s signal-to-noise-plus-interference ratio (SNIR) must be higher than […]

Noise Mitigation Techniques For Optimising LTE Network Performance

Why is ‘noise interference’ a challenge for LTE? LTE’s growth is rooted in the ever-growing demand for data speed and throughput. To meet this demand, LTE technology uses a number of methods and practices that can boost capacity—but leave it susceptible to stray noise interference. Because optimal LTE performance requires a higher signal-to-noise-ratio (SNR) than […]
