Voice over Wi-Fi: Cable versus LTE: Part II

In the article “How Big a Threat Is VoWi-Fi to the LTE Operator?”  (Video: https://www.youtube.com/watch?v=o8hgAzT073Q) I illustrated the potential threat cable voice-over-Wi-Fi is to the mobile network operator. In Part II of the LTE threat I look at this issue from the CxO’s point of view of each organization.

Cable executives see VoWi-Fi as “nothing but upside.” VoWi-Fi enhances customer bundles, adds new revenue opportunities and is technically achievable. From a network perspective, their HFC networks are widely deployed, minimize access point backhaul issues, and have a presence in millions of homes and small/medium businesses. This physical presence gives them instant Wi-Fi access points on which they can add voice services. Additionally, they have a voice backend, and they are well positioned to handle the additional voice traffic throughout their network. Given these strengths, they can and will move fast, hence, “nothing but upside.”
Mobile network operator (MNO) executives see Voice over Wi-Fi as “nothing but threats” to subscriber relationships, top-line revenue and profits and CAPEX flexibility. These threats are visualized in a number of ways. MNOs lack a physical presence in the home beyond the end-user devices with most users already off-loading to broadband delivered Wi-Fi for performance and data cap reasons. Although LTE backhaul networks have substantial capacity it is questionable whether they can gracefully cope with an onslaught of Wi-Fi data traffic. No company will deploy a voice-only Wi-Fi network. MNOs that do not own fixed network assets have a more daunting competitive environment; however, those that do have fixed network assets still have substantial challenges.
Cable is not without its own challenges. Given that they will be a new entrant to the mobile voice market they must meet certain baselines of quality of service, which will add to the deployment time, cost and complexity. Cable companies will never build out an LTE network. Never is a long time but, this is a safe bet. True, they can become MVNOs or be bold and buy Sprint or T-Mobile. Without LTE cable companies will not be able to offer the coverage MNOs can.
New Wi-Fi voice and data technologies are under development. Improvements to the over-the-air protocols to address fairness and contention are emerging but VoWi-Fi technologies are nascent and standards take time. All of this will delay cable’s first mover advantage.
MNOs have advantages as well. The biggest, as well as the most technically challenging, is intelligently leveraging their fixed and mobile networks to gain real-time insights of both networks’ end-to-end conditions such as congestion. Then, using these insights they can provide a superior quality of experience to their subscribers, particularly those deemed as high-value subscribers. For example, a default “off-load-to-Wi-Fi” strategy may not make sense for all subscribers if the Wi-Fi network is congested and the LTE network is not.
MNOs with small cells sites can upgrade them with LTE/Wi-Fi combo devices. The MNO has already solved the tough small cell site problems (real estate, backhaul, powering, etc.) so swapping out devices is manageable. Keep in mind that these small cell sites are not randomly dispersed. They are located in high-traffic, high-value locations. This enables the MNO to quickly expand its Wi-Fi network presence in these and high-value locations. Even more powerful is the ability to add Wi-Fi to its Self- Optimizing/Organizing Network investments.
The MNOs have a bold strategy available to them. They can move fast too, and because they have a carrier-class LTE network on which to fall back they don’t have to start with a gold plated Wi-Fi network. They state that they want to be more like web companies and deploy services fast and improve them over time. On this point, they can walk the talk and rapidly deploy a data-only Wi-Fi network that’s “good enough” and let their subscribers use it for free until they attain the level of quality they really want. A lesson from the web world is capturing customers quickly, which is paramount to success.
Voice-over-Wi-Fi has the real potential to be a major disruption to the service provider industry. Cable companies see this as nothing but upside, whereas mobile network operators see this as nothing but threats. Both have advantages and challenges. Cable has the footprint, voice backend and potential first mover advantage. Yet, as a new mobile voice entrant they have minimum quality thresholds they must meet to be credible. MNOs, on the other hand, lack a strong physical presence in the home and may face network capacity challenges with the addition of massive amounts of Wi-Fi data traffic. However, they have the ability, if bold enough, to take a page out of the web company playbook and move even faster to deploy a “good enough” data-only Wi-Fi network using today’s technologies and their current installed infrastructures.

The Future of Broadband CPE: Part I


At Stake: Who Controls the entire home, the service provider or the web company?
The network-terminating CPE device provided by the access network service provider is at an inflection point: it’s at the intersection of service providers’ business drivers and emerging technologies. What’s at stake is control of the entire home and all the revenue generating up-sell opportunities, including emerging Internet of Things services. Access network service providers must decipher this paradigm or risk being usurped by the web companies.
Customer Premise Equipment or CPE historically meant customer owned equipment. In the case of a T1 circuit the service provider would terminate the network with a CSU/DSU and would connect to the customer-owned access router. If there was an issue, the SP would perform a loop-back test to the CSU/DSU and if it passed the test they were done with support. The same is true with legacy home telephony. If there’s a dial tone at the Network Interface Device, the gray box attached to the outside your home, the telco is “done.” If you still have issues beyond that it’s your home wiring, which the ILEC’s no longer manage (for free anyway).
In the early days of broadband, the service provider, telco and cable company would terminate their connections with a DSL or cable modem. The premise facing interface was Ethernet (Layer 2 interface). When consumers wanted to connect more than one device to the Internet they would acquire a Wi-Fi router (Layer 3) through the retail channel.
Today, service providers are combining the modem functionality with the Wi-Fi routing functionality in to a single device. Interesting to note is the SP is taking ownership of the Wi-Fi network, something historically they were loathed to do and could not do for regulatory reasons. The more functionality an SP takes ownership of the more they are responsible for. This leads to the inevitable increase in help calls.
Competition is forcing them take ownership of the total customer experience. A poor experience combined with lackluster customer support is the number one reason for customer churn. Now the CPE or broadband gateway is taking on the dual role of terminating the network and controlling the home network and ultimately the devices and things in the home.
This is not without precedence. The set-top box has always had this dual personality. It terminated the SP’s video network and controlled the home video experience. This is even more prevalent with whole home DVRs. As far as cable companies were concerned the STB was part of the network when it was convenient and CPE when that was convenient.
Now and in the future the SP provided CPE device needs to do two things well. First, it must terminate the access network (Layers 1 and 2), hence the term “network terminating CPE”. Second, it must control and manage the entire home experience (Layers 3-7+). It can and will do the network terminating part well, but it also MUST do the home experience well or risk churn where competition exist or having a web company usurp them.
In future articles I will address numerous issues including:
1. Virtualization Options and Realities
2. IoT and Smart Home Implications
3. Distribution of Intelligence (Cloud, Network and CPE)
4. Distribution of Intelligence (CO/HE, Outside Plant and CPE)

Wi-Fi – “the toy that grew up”

Reprinted from the Wireless Broadband Association: Industry News Roundup
Wi-Fi – “the toy that grew up”
Historically, Mobile Network Operators (MNOs) looked at Wi-Fi as a toy, a low-end technology that was great to off-load data from networks. Now Wi-Fi is having a strategic impact on MNOs across the globe. Now the question is LTE or Wi-Fi: remind me which one’s for off-load?
Yet, as with many technical innovations, the low-end always wins. Wi-Fi is a classic example of this theory. Through a combination of Moore’s Law, economies of scale, R&D investments and free market dynamics Wi-Fi is king of the hill. In most developed countries people and things can access a Wi-Fi network in 80% of locations. Companies, such as Devicescape, have created virtual networks based on “ambient’ Wi-Fi networks. Hotspots are so ubiquitous that Opensignal launched an application to find the best one out of the many available.
Wi-Fi and Hotspots are becoming strategic to all carriers (fixed and mobile) as they have realized the importance of keeping traffic on their network for quality of experience and billing purposes. The market for carrier Wi-Fi gear continues to grow as carriers look to exploit these opportunities.
Today, high- speed access to the Internet is as fundamental as indoor plumbing. People expect it and city and national governments view it as mandatory for many economic development and quality of life issues. With the ubiquity of Wi-Fi enabled devices and the simplicity of Wi-Fi deployments it is no surprise that Wi-Fi is a leading candidate to achieve this. Even in remote,rural and under-developed regions, Wi-Fi leads the ways.
Even with fierce competition from ZigBee and other alternatives Wi-Fi is also a leading network technology for applications using IoT technologies. Wearables are no exception. LG smart watches use Wi-Fi and researchers are looking to Wi-Fi for an entire body network. We could all become Wi-Fi access points.
Yet success breeds challenges. Wi-Fi uses attractive unlicensed frequency bands and the licensed crowd wants in as the LTE community is looking to use the same 5 Ghz frequency band. Trying to head off a battle royale, the U.S. FCC has already entered the fray.
Wi-Fi, the toy that grew up, continues its momentum to solve real problems for consumers, businesses, service providers and governments. It was often said never to bet against Ethernet, I’d like to add never bet against Wi-Fi.

Access Insights™ At the Intersection of Service Provider Business Drivers and Emerging Technologies

What is “access”?  Simply put, it’s people and things accessing the cloud and each other. 
Access is no longer Fixed or Wireless.  Access is about connecting people and things to each other and to applications and service in “the cloud”.   Thus, access is about Fixed and Wireless.  It’s about having the right combined architecture on a neighborhood-by-neighborhood basis.  This “combo” trend is having, and will continue to have, major impacts and disruptions in the access market and in the entire service provider ecosystem.  New technologies, architectures and business models will emerge. Market realities are forcing carriers to offer (up to) gigabit speeds and incumbents have billions of dollars in deployed assets and architectures.  All this makes Access challenging for both technical/architectural and business decision making.    
I’ve determined that attention deficit disorder (A.D.D.) is a truly global phenomenon.  Therefore, I will present my points in terse salient bullets :-)
Top Access Insights to Ponder
  1. The future of Access is Fixed and Wireless… not “or”
    1. SPs need to adapt organizations, so do vendors!
  2. Gigabit Deployment Strategy
    1. Is timing everything? Plus...real strategic implications to the @$# Speed Test.
  3. Next Gen Broadband CPE architecture and business models are being disrupted...
    1. Big risk to incumbent service providers and Vendors
  4. Wi-Fi: The “toy” that grew up: Strategic implications abound
    1. Wi-Fi: Further proof that the “low end always wins”
  5. Voice over Wi-Fi
    1. Nothing but upside to Cable Companies. Nothing but threats to MNOs.
  6. LTE vs. Wi-Fi
    1. Remind me which one is for off-load?
  7. Next Gen Cable Access Networks …
    1. PON Greenfield is redundant, DOCSIS Greenfield is an oxymoron
  8. CPE vs. Carrier Gear (Plastic vs. Metal)
    1. Plastic companies building metal?
  9. SDN-NFV in Access
    1. It’s coming… contemplations begin…
  10. What’s the value of vendor incumbency at inflection points?
    1. Is Access different from any other industry?
There’s, hopefully obviously to the reader, a lot of thought behind each of these points.  I’d welcome the opportunity to discuss them in more detail.  Please contact me if you’d like to schedule some time explore how these insights impact your strategies and how we can create actionable plans to address and exploit them.

Broadband Regulations: Be Careful What You Wish For!

Regulations are a critical factor in the access network. Unlike the “rest of the network” the access network is burdened with federal, state and local regulations and this is only getting worse. I’ve written extensively in the past that net neutrality is a bad idea and that Title II is a gigabit killer.

Why is regulation bad for everyone, including Google? The regulated monopoly “phone companies” depreciated equipment over 30 years. With asset-based pricing regulations you want to keep your asset base as high as possible. Thus, the innovation cycle of the regulated voice industry was 30 years. In the unregulated data networking industry the desired depreciation cycle is five to seven years with three to five years being a more common life span of equipment. Thus, the innovation cycle is three to five years. Today, service providers want to accelerate their innovation cycle to less than one year and ideally three to four months to be more competitive with the “web companies” such as Google and Facebook.
Until recently the net neutrality debate was focused on adverse traffic impacts such a throttling P2P traffic. It’s widely reported that as few as 10 percent of users consume upwards of 80 percent of capacity. The numbers have changed with the proliferation of streaming video but the issue remains. Mobile network operators have solved this problem with data caps. They also have program where web companies can pay so their traffic doesn’t count against subscribers’ data caps. (This may be illegal soon as well.) When an analogous program (for example, paid fast lane) was implemented in the broadband access market there was outrage.
Traditional content delivery networks (CDNs) can bypass much of the public Internet to improve quality of service. Companies that want to provide a better user experience can use CDNs and cache their content in select Tier 1 locations across the country. This helps; however, from the Tier 1 cache to the user is best-effort delivery. Once the traffic enters the local exchange carriers’ (LEC) network in a large metropolitan area the “last 50” miles are best effort.
With this model OTT companies cannot ensure the quality of their service. Why shouldn’t they be able to pay the LEC for better traffic treatment? The argument is that this benefits the large companies at the detriment of start-up companies. It’s just another challenge innovative start-ups must overcome. This actually benefits consumers as only those companies with a compelling offering will make it over the hurdle. Marginal companies with a marginal offering won’t flood the market and the network with garbage. This is a good thing. Isn’t the FCC all about protecting the consumer?
Can capitalism and the free market address the issue of a “digital divide”? Yes, a case in point is Comcast in the Boston area. The company offers $10/month broadband service to any family that has children on the free or subsidized school lunch program in the city of Boston. No laws, no regulations just a solid business driven move by Comcast.
Service providers have invested billions of dollars deploying and managing broadband networks. Data rates have continuously increased. Gigabit networks are being deployed around the world by a range of companies and organizations. The free market is driving them. It’s counter intuitive to expect them to spend limited CAPEX if their return on investment is regulated or uncertain. Today, regulators are faced with conflicting priorities. On one hand they want to spur gigabit investments but on the other hand they want to regulate broadband access. It’s obvious that you can’t get both.To repeat: Title II is a gigabit killer.

Nokia and Alcatel-Lucent: Who Should Buy Who?


Seeking Alpha reported that Nokia confirmed it is in talks to acquire all or part of Alcatel-Lucent and it is no surprise the companes are quibbling over valuation. Alcatel-Lucent has gone through some tough times and appears to be executing well on its Shift plan. Arguably, they are undervalued but investors are waiting for more tangible results, which will indicate that the plan is working. Current shareholders and employees can sense this positive momentum and are remiss to “sell-out” before the results of their hard work and commitment are fully realized. 
Consolidation in the equipment market is not unexpected. Communication service providers are consolidating too and are getting bigger. When this occurs large equipment providers tend to consolidate as well as they have fewer large customers and need economies of scale to be successful. This is truly a zero-sum game. Either you get 70 percent of the business, 30 percent as a second, keep the first one honest, source or you get zero percent. With the inherent complexities of SDN, NFV and virtualization, particularly in multi-vendor integration, it may be years before the “second’ source is even added.
Driving this buyout could be Huawei. The company is disrupting the entire global telecommunication equipment market. The industry has been aware of the company’s “grey area” business practices such as outright appropriating technology and intellectual property to giving eNodeBs away for free, with customers just paying the yearly maintenance fees (with a bonus of dozens of undocumented back doors). Although this is disturbing to the industry what really is of concern is Huawei’s huge product portfolio, their ability to throw “armies” at initiatives and their ability to take a long-term view to market (and global) domination.
The big issue for either Nokia or Alcatel-Lucent is who is going to compete with Huawei? Communication networks are a fundamental asset to nation states. They drive economic development, entertainment, education, national security, etc. Perhaps it’s time all governments treat them as national assets.

Voice over Wi-Fi: Cable versus LTE: Part II
