I first came across the reference to Super-PON back in 1996 at an IEEE Communications Society Conference. At that time, Super-PON was described as supporting a split ratio of 1:1024 at a range of 100km. The overall network capacity of the Super-PON was 2.5Gbit/s TDM downstream and 300Mbit/s ATM-based TDMA upstream and it introduced the concept of optical amplifiers along the fiber paths. At the time this was particularly forward thinking, as the only PON systems that had been deployed were BPON systems supporting a split ratio of 32 subscribers and a capacity of 622Mbit/s / 155Mbit/s. For reference, GPON can support a split ratio up to 1:64 at a range of 20km with a network capacity of 2.5Gbit/s / 2.5Gbit/s ...

The ITU recently announced the formation of Focus Group Network 2030 (FG NET-2030) with the goal to study the requirements for networks beyond 5G. Targeting the year 2030 as the timeframe when forward-looking scenarios such as holographic type communications, volumetric video and haptic applications will be commonplace, this new focus group hopes to answer the question: What will this network architecture look like and what are the enabling mechanisms to enable these scenarios?

The worlds of entertainment and telecommunications continue to blend as technology has enabled a wealth of applications and services that cross both industries. The introduction of broadband services gave rise to internet TV – most notably, streaming video services such as Netflix. While the introduction of smart devices, such as the iPhone, forever changed the landscape of entertainment. These devices have enabled every individual to become a content creator – while apps such as Instagram, Facebook, and YouTube have created an entirely new ecosystem for content distribution and the revenue generated by it ...

Fixed wireless access (FWA) is experiencing a resurgence, as a growing number of operators in all regions of the world are leveraging their investments in mobile infrastructure (particularly 4G LTE and forthcoming 5G) to provide fixed broadband services. Why the resurgence? If one can recall, there have been two major industry attempts at this space. The first was wireless local loop (think LMDS from the late 1990s), but equipment was expensive and proprietary. The other major attempt was WiMAX, which never gained the promised market momentum or capabilities and was quickly overshadowed by a rapidly advancing mobile market with the introduction of LTE. But enough about the past …

Multi-access edge computing (MEC) is expected to play a strategic role as networks transform, bringing new levels of performance and access to mobile, wireless, and wired networks in support of future services and applications. A key goal of MEC is to reduce network congestion and improve application performance by moving functions, content and processing closer to the subscriber. By doing so, network operators will be able to better utilize network resources while also improving the delivery of content and applications to provide end users with a better quality of experience through lower latency and higher bandwidth ...
