5G

This is the first in a 3-part blog series. Timing & Synchronization If someone played a word association game on the topic of mobile telecommunications technology, the first things to come to mind would likely be cell towers, satellites, antennas, and of course smart phones. Most people, even in the industry, would never think of […]

Gigabit LTE technology is supposed to help service providers (SPs) overcome the data tsunami until 5G technology becomes commercially ready. At the same time Gigabit LTE will allow SPs to maximize on their current network investments by delaying significant upgrade costs and improving the spectral efficiency of today’s network. If optimized well, Gigabit LTE will […]

When we talk about 5G or any other wireless technology, our brain focuses on the wireless aspect of the technology. In reality, only the last hop of the wireless network is actually wireless. Most of the data communication happens over a wired network. RF spectrum being such a precious resource, mobile operators try their best […]

On March 22, VIAVI held a webinar on real-world narrowband IoT (NB-IoT) testing. The webinar covered IoT market trends, an NB-IoT technology overview, field testing scenarios, and NB-IoT measurements. But the best part by far was the Q & A! We got so many great questions, we decided to turn them into a blog post. […]

5G Fronthaul

This is the fourth in a series of blog posts on the Evolution of Fronthaul, links to other posts below. As wireless operators announce their plans for the introduction of 5G services, ecosystem players are developing and introducing a new range of capabilities to pave the way for a smooth transition from 4G to 5G. […]

FTTH-PON Q and A

Our recent webinar with Light Reading, Lessons Learned: Efficient Deployment & Maintenance of FTTH/PON Networks, garnered several questions from the attendees. We thought that even those who may not have caught the live webinar might benefit from this Q&A. If you’d like to see the webinar recording, please visit the Light Reading Testapedia page.  Q. Is […]

The evolution to virtualization and cloud, network automation, massive traffic growth, IoT, increasing service velocity and revenue growth…together with the advent of 5G.  These are just some of the challenges mobile service providers face today. Consumers are demanding that mobile services are always on, always available, and everything is connected. In response, operators are deploying […]

Part 3 of the Evolution of Fronthaul Networks (read Part 1: Intro to Fronthaul and Part 2: Fiber Deployment in Wireless) In parts 1 and 2, I described the overall radio access network architecture and best practices for deployment at physical layer which is primarily fiber for the links between the base band unit (BBU) […]

cellular towers

Part 2 of the Evolution of Fronthaul Networks (read Part 1: Intro to Fronthaul and Part 3: CPRI ) As we learned in part 1, fiber deployment permits the placement of RRH’s closer to the antenna. Also known as light radio, this RRH placement has significantly improved the energy efficiency of cellular networks as the […]

Fronthaul? Until few years it was unknown for most involved in network deployment. Smart phones, the explosive growth in use of media reach apps and the competitive pressure for operators to offer higher data limits have changed the role of fronthaul completely. One can hardly oversee the rising number of antennas and radios mounted on […]
