Professional testing is key in ensuring high QoE for VoLTE

This guest blog post was written by Kai Ojala, CTO, Anite Network Testing

The requirement for VoLTE is to offer high-quality voice calls and video calls, which as a baseline requires wide LTE coverage. LTE networks fulfill this aspect – especially lower carrier frequencies are deployed globally (e.g. 700 and 800 MHz frequency bands). Operators will benefit from customers switching to VoLTE services by harmonizing voice services and getting better capacity out of the spectrum.
Voice calls in LTE networks can be handled using Circuit Switched Fallback (CSFB) and Voice over LTE (VoLTE). CSFB provides a mechanism to transfer an initiated voice call to legacy circuit-switched networks. VoLTE, on the other hand, is a fully packet switched technology which uses Voice over IP (VoIP) technologies. With the SR-VCC functionality voice calls made with VoLTE can be switched over to legacy networks when the user moves out of the LTE network coverage.

Adding Capacity Is a “Small Cell” Matter

Everybody’s talking about them, but what exactly is a small cell? In many people’s minds, a small cell is a very low power femto cell, installed in a home or office. It’s a radio device. In my mind (and in many others, too), a small cell is anything that is not a typical macro site, deployed to solve a network capacity problem.

Small cells can be indoor or outdoor. They can vary in power level. Some are carrier grade, some are for consumers. But what defines a small cell is not one of these characteristics, but rather what a small cell is trying to do-add capacity in some manner besides a standard macro site.

What is Unknown RF Antenna position costing your company?

This guest post was written by John Vetter, VP of Business Development, Sunsight

Directional RF antenna installations are not always dantennaone to carrier RF design specifications for azimuth, mechanical tilt and roll.  Some before/after audits have shown that as many as 40% of antennas are installed more than five degrees off target.  Using this audit data, simulations are possible with RF network propagation software and any market final design project.  These results will prove that even when using conservative misalignment changes that induced network interference can be costly to carriers specifically for newer interference prone LTE technologies.  Focusing just on carrier spectrum capital investment this number can easily become surprisingly high when considering large nationwide RF spectrum investments.   The cost of ‘wasted’ spectrum due to interference does not, but could consider additional costs of ‘unused’ BTS/RAN infrastructure, unnecessary network performance troubleshooting efforts, less the credible output from RF propagation, ACP and SON tools , and more important, the effects of poor customer data experiences  -all caused by misaligned RF antennas.

In our work with mobile operators to accelerate small cell systems inside medium to large enterprises, we have learned much over the last five years to create win-win formulas for enterprise IT and our mobile operator customers. It is hard-earned knowledge that only a seasoned executive team could have anticipated and managed by an experienced field team.

So, in the spirit of sharing our knowledge, here are “5 Small Cell System Do’s and Don’ts of Enterprise.”

Ericsson made a splash at Mobile World Congress, describing and demonstrating their vision for 5G, and all the different use cases they envision for the technology.

Ahead of 5G Forum USA in Palo Alto in a couple of weeks, we had the opportunity to catch-up with Don McCullough, Director of Strategic Communications at Ericsson. During the interview, Don shared Ericsson’s work in innovating and defining the 5G landscape, their objectives and likely use cases for this next generation.
