Wi-Fi – “the toy that grew up”

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.

A Telco Energy Strategy Should Demand ZERO Impact on Service

 As energy strategies reach the boardroom, service provider management should insist on “zero-impact” on services.  The stakes are too high in the competitive zero-sum game they participate in.  Customer satisfaction, reduced churn and a strong brand are paramount in this environment.  By treating energy as a strategic initiative they will achieve the benefits of lower OPEX, enhance brand and more efficient end-to-end operations.  Tactical energy initiatives will not get funded if they have a perceivable adverse effect on consumer and business services.  These adverse effects could be short lived, as during installation, or long term, if, for example, latency is introduced.   Thus, their energy strategy should demand zero impact on services.

Note the emphasis on “services” instead of “network”.    It would be unreasonable to demand zero impact on the network if you are deploying a new architecture or energy aware protocol.  Yet, with IP (Internet Protocol) the impact on the network should not cause the perceivable impact on services. 

Is zero-impact unreasonable and wouldn’t “minimal impact” be a better goal?  The challenge here would be to define what “minimal” means?  Would it mean X amount of video anomalies per 30 minutes?  Why not X+1?  Would it mean Y dropped calls/tower/minute?  Why not Y+1?  Also, who defines X and Y? Would the CEO, CTO, or CMO define them?  Would international standards organizations set them? 

 Setting the goal of “Zero Impact” sends a clear message throughout the organization of what is expected.  Terms such as “sustainability” and “green” will have clearer meaning.  Green projects that make people feel good but have no financial justification will fail fast so the real winners can progress.  Therefore, telcos and service providers should demand Zero Impact on services.

Service Provider Energy Efficiency (SPEE) is Inevitable!

Network traffic is increasing exponentially and energy efficiency is increasing linearly.  Yet, network engineers are focused on, and measured on, scalability and availability.  They don’t see their energy expenses.   However, given the simple math of exponential verse linear growth it is inevitable that energy efficiency and energy management will be a primary driver in the near future. 

Energy Management: Focus of Nokia Siemens Networks

Nokia Siemens Networks (NSN) announced their Technology Vision 2020 recently.  Energy management was one of six major pillars.   The six pillars are:

1. Support up to 1000 times the capacity
2.  Reduce latency to milliseconds
3. Teach networks to be self-aware
4.  Flatten total energy consumption
5. Reinvent telcos for the cloud
6. Personalize network experience.

The key point regarding energy is illustrated in the following chart.

  

As shown, electricity alone accounts for 15% of total OPEX.  In developing markets this can be as high as 50% with a high percentage of off-grid sites.  If energy management is ignored the cost of power will continue to rise with the expected exponential growth in traffic.  The next chart illustrates that while traffic grows exponentially, energy efficiency grows linearly.  Thus, the amount and cost of energy will rapidly increase. 

Other key facts that NSN articulated are that the RAN (Radio Access Network) accounts for 80% of energy consumption and that current installed base-stations are 50% less efficient than new ones. 

As with any energy management and energy efficiency program there is no silver bullet or one solution to solve this.  However, there are numerous solutions when taken together add up to real savings in energy and money.  This area is too large for this short post.  For now, consider four main areas to investigate

1. Devices: Components, Moore's Law
2. Network Architectures
3. Network Management and Operations
4. Marketing and Services

By focusing on energy management and energy efficiency the end results will be meaningful OPEX savings, reduced carbon footprint and an enhance brand for sustainability conscious consumers.

Introduction

The focus of Greywhale Research is Energy Management in IP Networks, both the service provider and the large enterprise.  We focus on the technologies, markets and business issues in this emerging area.

Energy Management in IP networks is a nascent marketplace.  Why focus on this area?  First, the Internet is expected to consume 4% of the world’s electricity up from 2%.  Reductions in this area can have tremendous economic and environmental benefits.  Currently IP Traffic growth is exponentially outpacing energy efficiency in both fixed and mobile networks.  A small percentage of energy savings translates into $Billions in energy cost.  Savings here, as in any OPEX, results in cash delivered to the bottom line. 

Second, sustainability for service providers and large companies is moving beyond saving money to becoming a strategic competitive advantage.  Consumers demand “green” and sustainability enhances the brand.  With a “bit” being a “bit” and a “packet” being a “packet” the brand image is critical to capture and retain customers.  Additionally, the global financial markets now link sustainability to management sophistication.

Given these reasons, the time is right to examine energy management and efficiency in large IP networks.  Please join us in the new journey.
