TeleDynamics Think Tank

Last week, we touched on some of the technological advances that have allowed VoIP telephony to surpass the PSTN in both quality and reliability.

Yet, even though VoIP has been around for two decades, there are still some misconceptions about what it really is. A lot of people think of VoIP as a technology that allows placing phone calls over the internet. Although this is true, such a narrow definition encompasses only a fraction of the functionality of VoIP.

The unfortunate consequence of this misperception is that VoIP is often associated with low quality and best-effort services that offer low cost or free voice calls over the internet. Those familiar with these services have experienced the frequent disconnects, jitter and stuttering on the line characteristic of this type of service. As a result, VoIP has erroneously been associated with an unreliable user experience.

The truth is, VoIP is much more (and better) than just voice over the internet.

Quantum-leap technology advancements will enable on-demand services anytime, anywhere, with ubiquitous connectivity.

Nordic Mobile Telephony (NMT) was introduced as the first 1G system in the Scandinavian countries in 1982. 2G was commercially deployed in 1992 and 3G launched commercially in 2001, allowing mobile data as a mainstream service. 4G has been deployed since 2012, and is still being deployed around the world in developing markets, and 5G is on the horizon for the early- to mid-2020s. On average, we deploy a new generation of mobile communications every 10 years. In 25 years’ time, we will have deployed 7G and be well underway with design of the specifications for 8G, where wireless high-definition video streaming and virtual reality are part of the everyday norm. We will have transformed ourselves from the Digital Era of the 1990s to 2020, to the Digital Era of Automation from 2020 and beyond, which will be an all-immersive, high-definition user experience, taking us seamlessly from Gigabytes GB = 10⁹ of data to Zettabytes ZB = 10²¹.

As one of the biggest expenses of any business, telecommunications solutions should be both reliable and cost-effective. One telephony network design aspect that can provide both is the direct connection of the IP phone system to a mobile network.

Here we explore two ways to do this, either of which not only achieves cost savings for the company but also enhances reliability by providing an additional redundant and overflow route.
