2015 Through the Looking Glass

2015 Saguna on the Rise2014: Saguna on the fast lane

The past year has been an eventful and exciting one at Saguna. As we reflect on 2014, we are already caught up in the action that 2015 brings with it.

In 2014 several pilots and field trials were deployed around the world. As a result our solution made a tremendous step forward and was certified for general availability and sales by a leading network equipment vendor. To support the momentum, our team grew by 17%, and we moved to new offices.

As you know, Saguna targets leading global mobile operators and network equipment vendors. A pioneer of Mobile Edge Computing (MEC), Saguna is bringing content, applications, and a variety of Internet services into the RAN (Radio Access Network), as close as possible to mobile users. This means that every integration, every trial and, certainly, every deployment  is a significant endorsement to our approach and that our solution can live up to its promise: serving mobile broadband users in the fastest best way possible.

As  we consider the development of trends in mobile network infrastructure, Saguna’s outlook for 2015 is very exciting. In a world where mobile usage keeps increasing exponentially, there are many ways to grow, improve and profit.  Here are the main ones:

 Through the looking glass: the acronyms that matter

The promise of MEC – In Q3 of 2014 Saguna joined the European Telecommunications Standards Institute (ETSI) new Mobile-Edge Computing (MEC) Industry Specification Group (ISG), partnering with industry vendors, mobile operators and content providers to create a new standard.  The concept behind Edge Computing in general, is to bring computational power as close as possible to the user – but not on the user equipment (UE) itself. In Mobile networks, the Radio Access Network (RAN) is the part of the network that is closest to mobile users. Until now, however, the mobile network “brains” resided inside the core network far from the mobile user.

 In MEC, computational power is distributed and brought into the RAN, speeding up content delivery to the users, while reducing the amount of data traversing the network. To learn more about MEC and our involvement, take a look at the Q&A post with our CTO, Danny Frydman.  We expect the MEC standardization efforts and work to continue into 2015 and conclude in early 2016.

HTTPS on the rise – in the US, Europe and LATAM – the share of secured mobile data is on the rise and its growth is expected to continue.  While secured data is a good thing, it has its effects the user experience. These include the time needed for the HTTPS handshake, mainly additional roundtrips that dramatically degrade the user experience, and the lack of real time information regarding network conditions, which prevents creating an enhanced user experience.

Here, as well, Saguna comes to the rescue, bringing content closer to the users, yes, even https content.  The Saguna CODS CDN-Extend enables CDN providers to integrate a server-side CDN application into the mobile base station, running on the Saguna CODS Open-RAN platform.

NFV – virtualization is here.  The idea behind virtualization is to make mobile networks faster and more flexible, so that it is easy to introduce new services and applications. Network Functions Virtualization (NFV) essentially separates the physical underlying infrastructure and the software computational level.

In mobile networks NFV implementations can be adopted across the entire network; from the Radio Access Network (RAN) to the Core network.

Saguna is a true fan of NFV, and as we describe in a post dedicated to NFV and content delivery. Leveraging the inherent flexibility of NFV, our solution operates inside the mobile base station or RAN aggregation point. It creates fast track connections to mobile users, while preserving user mobility and core network functionality.

LTE all around us– LTE shows a significant increase in subscriber numbers. The first LTE deployments occurred in Finland and Sweden, and the world’s largest LTE network is in the USA, but emerging APAC and LATAM have the highest number of planned LTE networks, according to research firm Analysys Mason.

LTE Growth

At first, the majority of mobile operators deploying LTE offered unlimited data usage to their subscribers. Soon enough, it became clear, that the networks become congested again, and the big players started throttling data speed for users. Earlier in the year, we shared with our blog readers how Saguna can help solve this conflict; operating an Open-RAN platform that delivers content and applications to mobile users directly from the 4G RAN.

So, it sure looks like 2015 brings with it exciting news for us at Saguna, presenting challenges, big and small. As the year starts, we are looking forward these challenges and many more as we make our mark in our Mobile-First world.
