Insight: SDN Deployment Considerations

Memorial Day is over, and it's back to business as usual--which includes pondering a number of factors related to deploying Software-Defined Networking (SDN). 

For one thing, there's a lot of buzz about not only SDN but "software-defined everything" or SDx. SDxCentral pointed out that for most of networking's history, changes came mostly through hardware-based innovations. Now, software is driving adaption, forces dramatic changes.

Insight: Google Fi QoS and QoE Implications

Google recently announced its beta Google Fi (aka Project Fi) service, a mobile plan with pricing based on actual data usage. This is a potentially disruptive move in the U.S. where carriers mostly offer "bucket" plans. While on the surface, Google Fi seems like great news for consumers (at least those who get invited and use the Nexus 6 smartphone, the only device on which it's currently supported), the service does present some network performance and user experience issues worth exploring.

Webinar Tomorrow: Preparing for VoLTE

There have been a lot of false starts with VoLTE, mostly related to issues with synchronization and timing where requirements are especially tight. There are also problems with packet loss and backhaul quality. Unlike with circuit-switched calls where quality can degrade, VoLTE is either on or off: if there's unreliable bandwidth, or bandwidth is just on the edge when capacity increases, calls get dropped.Roaming handoffs between towers requires exceptionally tight precision.

Before committing to developing a region for VoLTE, operators can and should check to make sure their network is ready. Load testing the network, simulating traffic types, and using MOS is an method of understanding if and where there are network pinch-points so they can be addressed. This way, the operator can have confidence when rolling out VoLTE that they won't disappoint subscribers.

Accedian's VP of Solutions Development and Marketing, Scott Sumner, dives into this topic in a micro webinar (15 minute presentation, 15 minute Q&A) May 14, 2015, at 11:30am ET. (Register here.) Part of our Low Latency Learning Series, this webinar looks at the architectural and performance assurance challenges operators face as they plan for and deploy VoLTE services.

Insight: Small Cell Business Models and Opportunities

In response to customer needs, there's a growing focus in the wireless industry to improve indoor coverage using distributed antenna systems small cells, (DAS), Wi-Fi, and other technologies. But, RCR Wireless notes, spreading capacity and coverage through large buildings is often an engineering challenge. 

A recent Mobile Experts report, RCR Wireless said, predicted the in-building wireless market will double in the next three years, driven by growth in twisted pair cabling and low-cost signal sources. There's a convergence underway of DAS and cloud radio access networks. Small cells and carrier grade Wi-Fi are also influential. 

In another recent RCR Wireless article, SpiderCloud Wireless SVP and CMO Ronny Haraldvik stressed the importance of understanding how DAS and small cells differ, to be clear on their role in improving coverage. Although some vendors have started marketing DAS products as small cells, they are different technologies. 

A small cell, he explained, is an operator-controlled, low power radio access node. Some, but not all, small cells are based on femtocell technology (standards, software, etc.). DAS systems, on the other hand, are spatially separated antenna nodes connected to a common source. 

The similarity between DAS and small cells is their purpose: to provide wireless service within a geographic area or structure. Customers don't care what technology is used, so long as it works. Modern small cells tend to be less expensive and provide faster ROI than traditional DAS. 

Coverage challenges aren't limited to indoors, of course. 

Atlantic-ACM senior partner Aaron Blazar noted in an RCR Wireless Analyst Angle article that the best way to resolve outdoor densification deployment economics remains a big question in the wireless infrastructure market. Consolidating the value chain between site and fiber businesses has great potential.

The way that's traditionally been done, Blazer explained, is to have partnerships between leasing entities and fiber network infrastructure providers. The economics of that model, though, are hard to pull together. Finding the right combination of assets for cost-efficient deployments is the key. 

As carriers search for workable business models, RCR added in another article, they'll need to abandon the macro mindset before small cells can really take off. Adding capacity to network using small cells can be very effective, but the investment is often hard to justify.

Attaching small cells to existing structures in urban areas--like street light poles--are an opportunity for carriers to create mini cell towers where they are most needed, said Crains Cleveland Business. Carriers are increasingly taking advantage of that, despite the cost and effort involved. The number of small cells in the U.S. is predicted to jump from 40,000 to 52,000 this year--an increase of 30%.

And, the opportunity for small cells isn't limited to major carriers expanding coverage in cities. Mobile World Live interviewed Small Cell Forum CEO Sue Monahan, who said there is a wealth of opportunity for this technology, with applications ranging from transport (e.g. ships and planes), to disaster recovery, to industry (e.g. mines and oil rigs). 

Basically, Monahan's stance is that small cells can and should be used any place there isn't wireless coverage already. 

Indeed, as RCR Wireless editor Martha DeGrasse pointed out, applications for small cells include home use (femtocells), urban outdoor deployments, indoor enterprise deployments, high-capacity venues like sports arenas and convention centers, and rural deployments. 

What other application opportunities do you see for small cells?

Insight: What is MOS and Why Does it Matter?

Mean Opinion Score, or MOS, was originally developed to assess the quality of voice over IP (VoIP) calls using a scale of 1-5 (5 being the highest quality). That ranking system was developed by having thousands of people listen to the same playback and rate their quality subjectively. 

Over time, scientific MOS models have evolved, and it is now a quantifiable calculation. Packet loss, delay, jitter, and other basic metrics are examined to estimate--with a high degree of accuracy--what the sound quality will be like for any individual user. MOS calculated this way correlates very well with human experience.
