4G as a mobile telecommunications technology has been bandied around for over a decade or so and has appeared prematurely in several guises, predominately due to industry rumors, gossip and, alas, hype ...

The new “enhanced” primary reference time clock (PRTC) recommendation from the International Telecommunication Union (ITU), G.8272.1, looks set to be one of this year’s key innovations in the world of network synchronization. Aimed at producing the levels of accuracy necessary for 5G, enhanced PRTCs (ePRTCs) go far beyond the current technology. While the time output of today’s PRTCs should be accurate to within 100ns of Coordinated Universal Time (UTC), this new generation of clocks promises to deliver time to within just 30ns. ePRTCs also offer a greater level of reliability – unlike current PRTC technology, which has no holdover specifications, the emerging enhanced clocks are able to hold time accurately for 14 days, ensuring time service performance during GNSS outages ...

Most of us enjoy our broadband connectivity through traditional methods of fixed (DSL, cable, fiber) or wireless (3G/4G, satellite, FWA). However, there remains a significant portion of the world’s population where those methods of connectivity are either impractical or simply too expensive to pursue ...

After many ambitious starts by operators hoping to build gigabit networks, the reality sets in. Building out fiber to all premises is difficult, slow, complicated and expensive. In order to achieve a reasonable ROI, many operators avoid locations that are difficult to serve, resulting in these high-speed, high-quality networks going to only a chosen few. This not only widens the digital divide but also makes the goal of a “gigabit society” difficult to achieve ...
