5G Challenges Current Timing & Sync Standards Investment in the mobile ecosystem is driven by seemingly insatiable consumer demand for mobile bandwidth. Supplying it to them is arguably a great business to be in. Mobile operators will continue to compete for market share by deploying 5G for more bandwidth capacity, and adding more radio towers […]
This is the fifth in a series of blog posts on the Evolution of Fronthaul, links to past posts below. Preparing for Massive MIMO and 5G As CPRI technology is increasingly being deployed in cell densification and CRAN projects, eCPRI is starting to receive the attention of the global wireless community. As I outlined in […]
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. […]
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. […]
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 baseband unit (BBU) and […]
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 […]
