Webinar of the Week Blog Series | Ever since the FCC opened up wireless spectrum bands in 1985, Wi-Fi has kept evolving. The availability of low cost unlicensed Carrier-grade spectrum and its widespread use make Wi-Fi the technology of choice for offloading cellular networks at the dawn of “The Internet of Things”. The fact that Wi-Fi is a well-known mature technology, that it is easy to deploy and does not interfere with cellular networks further secure its lead.

Did you know that it took 25 years to transition from DSn/PDH to SONET/SDH (1962 -1987), 14 years to transition from 2.5G to 40G (1990 – 2004), but only 5 years for 100G to go from definition to mass deployment (2009 – 2014)? High Speed is happening faster than any other rate deployment. Here is an infographics that illustrates how quickly networks are evolving and some tips on how to get ready for what will happen next.

One of my areas of interest is mobile technologies and services. As you know, the mobile network is experiencing a paradigm shift: instead of delivering services via a wide Radio Access Network (RAN), operators and the general mobile industry is now looking at another approach: densification.

Cable-Tec Expo is just around the corner and I am happy to announce that one of my papers has been selected to be presented at the event on September 22. The paper, entitled Optical spectral planning for 40G/100G deployments: tradeoffs and their impacts, covers the definition of coherent vs non-coherent, as well as greenfield vs brownfield and their respective tradeoffs in terms of bandwidth, scalability, and impact on the quality of service. It also explores some avenues for network upgrade for greenfield and brownfield next-generation technologies.

Webinar of the Week Series | Copper is not dead. In fact, with an increasing number of people working from home, residential DSL technologies still have long days under the sun. The very high speeds recently achieved over copper pairs help DSL stand its ground firmly against the more costly fiber alternative.

When it comes to bringing triple-play services to businesses and residential customers, DSL is still the most widely deployed broadband access technology across the globe. This is not surprising, given that the copper plant is one of the most economical options available for the delivery high-value broadband services.

Customer churn hurts. Losing customers is bad enough, but the negative word-of-mouth that often ensues adds insult to injury by damaging opportunities with prospective customers. In today’s customer-centric telecommunications market—characterized by high demand for new services and fierce competition—a damaged reputation is baggage that mobile network operators can’t afford.
