Poor In-building Coverage Leaves Valuable Licensed Spectrum Under-utilized

Signals Research Group Finds Outdoor Macro RAN Unable to Provide Coverage and Capacity Requirements of Businesses and Public buildings

San Jose, California, February 25, 2013 SpiderCloud Wireless, Inc., a leading provider of scalable small cell Enterprise Radio Access Network (E-RAN) systems to mobile operators, today announced the results of a research study by Signals Research Group into the utilization of licensed spectrum in range of in-building environments, including college and enterprise campuses, high-rise buildings, shopping malls, hotels and airports. The research found that as much as 88% of an operator's licensed spectrum was underutilized in enterprise campus buildings, while on upper floors of high rise buildings a mobile device could handover as many as 51 times, due to the constantly fluctuating signal strength between all the visible cell sites.

The results of the study reveal the limitations of serving in-building coverage primarily by an outdoor macro network and that coverage inside does not equate to sufficient capacity for an ever-growing demand for always-on broadband. With approximately 80 percent of all mobile voice and data traffic occurring indoors, the in-building mobile data user consumes a disproportionate amount of network resources, requiring the outdoor macro network to assign more resources relative to the outdoor mobile device for a given end-user data rate.

"When operators attempt to use the outdoor macro network to provide in-building coverage and targeted capacity to a relatively small geographic area, this research shows that they are falling short. Their spectrum, which is their most valuable asset and in which they've invested billions of dollars, is not only being under-utilized, in some indoor scenarios isn't being used at all," said Michael Thelander, CEO, Signals Research Group. "However, while there are indoor coverage and capacity alternatives that give the user a range of ways to obtain connectivity, the outdoor user has no other means. It is the RAN or nothing. So, by shifting the in-building mobile voice and data traffic on to an in-building solution, not only is in-building coverage and capacity improved but there is also a direct impact on the capacity of the outdoor macro network."

The construction materials used in a building were also found to have a direct impact on indoor coverage. Signals Research Group found that an unintended consequence of material designed to be more energy efficient was that it was also very effective at blocking RF signals from the outside. The material is designed to keep sunlight out and control air temperature by absorbing large amounts of radiated signals. However, the RF signals from the outdoor macro RAN were also adversely affected.

A range of in-building scenarios were tested by Signals Research Group, including college and enterprise campuses, high-rise buildings, shopping malls, hotels and airports. Highlights of the research results include:

  • Enterprise campus: The utilization of spectrum can vary immensely between buildings on a single campus site. While in some buildings 100% of available spectrum was used, SRG found that in other buildings the utilization rate was as low as just 12%. The combination of lack of an in-building solution and the construction materials used in the building all affected the indoor coverage and capacity - and this is despite the fact that one of the buildings housed over 500 employees and was the global HQ for a universally recognized brand.

  • University campus: In performance tests conducted on a university campus, on average just 30% of the spectrum was utilized indoors. On some floors of the buildings that were tested there was extremely poor or non-existent coverage, while in other buildings it was nearly 100%. Capacity requirements compounded the issue due to the propensity of students with smartphones to consume large amounts of data in a concentrated indoor environment.

  • High-rise building: Sometimes a building can also have too much coverage. High-rise buildings in particular can be exposed to a large number of visible cell sites, causing high interference level. Signals Research Group found that just walking around one floor of a high-rise building could require a mobile device to handover as many as 51 times, due to the constantly fluctuating signal strength between all the cells. This has a direct impact on the performance of the device, significantly impacting battery life. Furthermore, because the device is effectively always operating at the end of a constantly changing cell, throughput is affected in a way that is akin to the cell suffering from limited capacity. Users in a downtown high-rise environment therefore share network resources not only with outdoor users, but also with users in adjacent buildings.

  • Hotels: While larger hotels sometimes have in-building solutions, the experience between hotels was marked. A San Francisco hotel had a spectrum utilization of just 38%, in contrast to a Dallas hotel, which hit 61% spectrum utilization.

Signals Research Group points out that Wi-Fi is not always an adequate alternative to in-building cellular coverage and capacity in the hospitality sector as an acceptable alternative for cellular voice. Voice over Wi-Fi mobility and throughput falls well below the threshold that signifies a good mobile data experience as soon as many users are congregated together and connected to the Wi-Fi service.

"This research proves what people's personal experience of having poor indoor coverage at work or network congestion at the shopping mall is already telling them - the user experience of in-building coverage and capacity is at best mixed and at worst practically non-existent," said Ronny Haraldsvik, CMO, SpiderCloud Wireless. "Not only that, but recent end-user research uncovered that over one third of senior IT managers would be likely to move to a wireless carrier that could guarantee better indoor mobile coverage and capacity. This makes for a coverage and capacity double-whammy. Not only is valuable spectrum being left underutilized, but it is also directly impacting the end-user experience and creating opportunities for subscriber churn."

How do APIs and IoT relate? The answer is not as simple as merely adding an API on top of a dumb device, but rather about understanding the architectural patterns for implementing an IoT fabric. There are typically two or three trends: Exposing the device to a management framework Exposing that management framework to a business centric logic Exposing that business layer and data to end users. This last trend is the IoT stack, which involves a new shift in the separation of what stuff happens, where data lives and where the interface lies. For instance, it's a mix of architectural styles ...
We certainly live in interesting technological times. And no more interesting than the current competing IoT standards for connectivity. Various standards bodies, approaches, and ecosystems are vying for mindshare and positioning for a competitive edge. It is clear that when the dust settles, we will have new protocols, evolved protocols, that will change the way we interact with devices and infrastructure. We will also have evolved web protocols, like HTTP/2, that will be changing the very core of our infrastructures. At the same time, we have old approaches made new again like micro-services...
Connected devices and the Internet of Things are getting significant momentum in 2014. In his session at Internet of @ThingsExpo, Jim Hunter, Chief Scientist & Technology Evangelist at Greenwave Systems, examined three key elements that together will drive mass adoption of the IoT before the end of 2015. The first element is the recent advent of robust open source protocols (like AllJoyn and WebRTC) that facilitate M2M communication. The second is broad availability of flexible, cost-effective storage designed to handle the massive surge in back-end data in a world where timely analytics is e...
Collecting data in the field and configuring multitudes of unique devices is a time-consuming, labor-intensive process that can stretch IT resources. Horan & Bird [H&B], Australia’s fifth-largest Solar Panel Installer, wanted to automate sensor data collection and monitoring from its solar panels and integrate the data with its business and marketing systems. After data was collected and structured, two major areas needed to be addressed: improving developer workflows and extending access to a business application to multiple users (multi-tenancy). Docker, a container technology, was used to ...
The true value of the Internet of Things (IoT) lies not just in the data, but through the services that protect the data, perform the analysis and present findings in a usable way. With many IoT elements rooted in traditional IT components, Big Data and IoT isn’t just a play for enterprise. In fact, the IoT presents SMBs with the prospect of launching entirely new activities and exploring innovative areas. CompTIA research identifies several areas where IoT is expected to have the greatest impact.
The 4th International Internet of @ThingsExpo, co-located with the 17th International Cloud Expo - to be held November 3-5, 2015, at the Santa Clara Convention Center in Santa Clara, CA - announces that its Call for Papers is open. The Internet of Things (IoT) is the biggest idea since the creation of the Worldwide Web more than 20 years ago.
The Industrial Internet revolution is now underway, enabled by connected machines and billions of devices that communicate and collaborate. The massive amounts of Big Data requiring real-time analysis is flooding legacy IT systems and giving way to cloud environments that can handle the unpredictable workloads. Yet many barriers remain until we can fully realize the opportunities and benefits from the convergence of machines and devices with Big Data and the cloud, including interoperability, data security and privacy.
The Internet of Things is tied together with a thin strand that is known as time. Coincidentally, at the core of nearly all data analytics is a timestamp. When working with time series data there are a few core principles that everyone should consider, especially across datasets where time is the common boundary. In his session at Internet of @ThingsExpo, Jim Scott, Director of Enterprise Strategy & Architecture at MapR Technologies, discussed single-value, geo-spatial, and log time series data. By focusing on enterprise applications and the data center, he will use OpenTSDB as an example t...
The Internet of Things is not only adding billions of sensors and billions of terabytes to the Internet. It is also forcing a fundamental change in the way we envision Information Technology. For the first time, more data is being created by devices at the edge of the Internet rather than from centralized systems. What does this mean for today's IT professional? In this Power Panel at @ThingsExpo, moderated by Conference Chair Roger Strukhoff, panelists will addresses this very serious issue of profound change in the industry.
Scott Jenson leads a project called The Physical Web within the Chrome team at Google. Project members are working to take the scalability and openness of the web and use it to talk to the exponentially exploding range of smart devices. Nearly every company today working on the IoT comes up with the same basic solution: use my server and you'll be fine. But if we really believe there will be trillions of these devices, that just can't scale. We need a system that is open a scalable and by using the URL as a basic building block, we open this up and get the same resilience that the web enjoys.
We are reaching the end of the beginning with WebRTC, and real systems using this technology have begun to appear. One challenge that faces every WebRTC deployment (in some form or another) is identity management. For example, if you have an existing service – possibly built on a variety of different PaaS/SaaS offerings – and you want to add real-time communications you are faced with a challenge relating to user management, authentication, authorization, and validation. Service providers will want to use their existing identities, but these will have credentials already that are (hopefully) i...
All major researchers estimate there will be tens of billions devices - computers, smartphones, tablets, and sensors - connected to the Internet by 2020. This number will continue to grow at a rapid pace for the next several decades. With major technology companies and startups seriously embracing IoT strategies, now is the perfect time to attend @ThingsExpo, June 9-11, 2015, at the Javits Center in New York City. Learn what is going on, contribute to the discussions, and ensure that your enterprise is as "IoT-Ready" as it can be
Container frameworks, such as Docker, provide a variety of benefits, including density of deployment across infrastructure, convenience for application developers to push updates with low operational hand-holding, and a fairly well-defined deployment workflow that can be orchestrated. Container frameworks also enable a DevOps approach to application development by cleanly separating concerns between operations and development teams. But running multi-container, multi-server apps with containers is very hard. You have to learn five new and different technologies and best practices (libswarm, sy...

The Internet of Things is a misnomer. That implies that everything is on the Internet, and that simply should not be - especially for things that are blurring the line between medical devices that stimulate like a pacemaker and quantified self-sensors like a pedometer or pulse tracker. The mesh of things that we manage must be segmented into zones of trust for sensing data, transmitting data, receiving command and control administrative changes, and peer-to-peer mesh messaging. In his session at @ThingsExpo, Ryan Bagnulo, Solution Architect / Software Engineer at SOA Software, focused on desi...
SYS-CON Events announced today that MetraTech, now part of Ericsson, has been named “Silver Sponsor” of SYS-CON's 16th International Cloud Expo®, which will take place on June 9–11, 2015, at the Javits Center in New York, NY. Ericsson is the driving force behind the Networked Society- a world leader in communications infrastructure, software and services. Some 40% of the world’s mobile traffic runs through networks Ericsson has supplied, serving more than 2.5 billion subscribers.
While great strides have been made relative to the video aspects of remote collaboration, audio technology has basically stagnated. Typically all audio is mixed to a single monaural stream and emanates from a single point, such as a speakerphone or a speaker associated with a video monitor. This leads to confusion and lack of understanding among participants especially regarding who is actually speaking. Spatial teleconferencing introduces the concept of acoustic spatial separation between conference participants in three dimensional space. This has been shown to significantly improve comprehe...
