Connecting DAS over existing PON Installations

Leveraging Networks for Connecting DAS Demand for higher wireless data throughput and denser wireless networks is driving the installation of distributed antenna systems (DAS) as well as small cells and Wi-Fi systems. But without existing fiber from the central office, deploying these devices can be a time-consuming and expensive proposition. At the same time, competition […]

The Benefits of Cell Virtualization For Wireless Operators

What is C-RAN and Cell Virtualization? Virtualization is a technique for wireless operators seeking to reduce capital costs and increase flexibility in their networks. To date, virtualization has focused on NFV for hardware-based functions, and cloud-RAN (C-RAN) enables NFV for mobile base station hardware. C-RAN is an acronym commonly heard in the wireless industry these […]

How Can SDN and NFV Facilitate Network Convergence?

Explore how SDN and NFV can facilitate network convergence New technologies such as software-defined networks (SDN) and network function virtualization (NFV) can facilitate network convergence. Traditionally—and often still today—dedicated access networks for wireless and wireline coexist as they each require dedicated appliances to run different protocols and services. Today, SDN and NFV allow a single […]

5G Vision With Converged Network Architecture

The 5G vision will be realized in the converged network in three fundamental ways: through densification, virtualization, and optimization of the network. Densification If 5G is really going to deliver speeds 10 or more times faster than 4G, reason dictates this will require more base stations in a given area—increasing the density of the network […]

5G: Advancing the World of Connectivity

The Main Drivers for 5G Connectivity: 5G wireless technology has many hopes and promises associated with it, including delivering up to 10 Gbps of throughput per user with much denser networks and super-low latency speeds. Although not expected to be standardized until 2018, 5G is clearly transitioning from an industry vision to a tangible, next-generation […]

Power Supply Comparison: Small Cells, Wi-Fi Hotspots, and HD Security-Camera Access

In the previous blog, we discussed the challenge of how to get power to devices in unusual places. Another consideration is the type of power supply to use for powering the cable and how to safely and properly disseminate power off the other end to ensure delivery of the right energy levels to the network […]

Power Supply Challenges with Small Cells, Wi-Fi Hotspots, and HD Security-Camera Access

We Need Power Where? The challenge of how to get power to devices mounted on lamp posts, tops and sides of buildings, security fences, and many other unusual places can often be the very last thing on an engineer’s mind. Take the case of small cells. What’s the first thing any good 4G-network planning engineer […]

Glossary of RF Path Terms

We’ve put together a blog post compiling a RF path glossary with a list of terms that are commonly used in radio frequency applications. Alternating Current (AC) An electrical current that changes polarity (i.e., direction) 50 to 60 times per second. It offers significant efficiencies when transmitted across power lines, making it the standard current […]

Maximizing Capacity With Microwave Backhaul

Network capacity and managing demand Simply put, capacity is a network’s ability to handle transmission traffic. In the case of cell communications, this traffic means voice and data – often, a great deal of data. As capacity demands continue to rise with the spread of long-term evolution (LTE) and 4G mobile devices, smart planning becomes […]

Interference Isolation Techniques for Transmitters and Receivers in Antenna Systems

Achieving sufficient isolation The correct degree of isolation between transmitters and receivers can be implemented by one of two methods: 1) Use two antennas, physically separated by a given distance, or; 2) Use the appropriate duplexer with a single-antenna system. Let’s examine the first option of two physically separated antennas. Within this option, there are […]
