AT&T Enhances Mobile Internet Coverage In The Detroit Marriott Renaissance Center

New 4G LTE Distributed Antenna System Provides Additional Wireless Capacity for Customers

DETROIT, Jan. 4, 2013 /PRNewswire/ -- As part of its continuing network investment to support growing demand for advanced wireless devices and services, AT&T* has improved its mobile Internet coverage at the Detroit Marriott Renaissance Center by completing the installation of a new 4G LTE-capable Distributed Antenna System (DAS).  


A DAS installation consists of multiple strategically-placed antennas that distribute AT&T's wireless network coverage throughout the Marriott, providing for more efficient management of wireless capacity in heavily-trafficked areas including guest rooms, the hotel lobby, ballrooms, guest circulation areas, meeting rooms, executive offices, fitness club, and more. DAS has the ability to provide enhanced, more consistent wireless coverage to customers in indoor or outdoor spaces where geographical limitations – terrain, building construction, etc. – or crowd density might otherwise prevent the optimal wireless experience.

"We want our customers to have a great network experience wherever they are, no matter what they're doing – whether that's making a call, checking email, downloading apps or surfing the Internet," said Jim Murray, president of AT&T Michigan. "We're committed to our investment in the local wireless network, and providing enhanced wireless coverage at Renaissance Center is just one way that we're investing in Detroit."

The additional capacity is expected to help improve call reliability, boost data traffic capacity and enable more consistent network access so customers make the most of their AT&T devices.

This unobtrusive network solution is just one innovative approach AT&T is taking to ensure it provides a seamless and effortless customer experience.  AT&T's innovation and investment have resulted in the nation's largest 4G network, covering more than 285 million people with ultra-fast speeds and a more consistent user experience. That's coverage in 3,000 more 4G cities and towns than Verizon.**

AT&T has deployed two compatible 4G technologies to deliver more speed to more customers, which means AT&T customers can get 4G speeds outside of 4G LTE areas on 4G HSPA+, unlike competitors, where smartphone customers fall back to slower 3G technologies when outside of LTE coverage. Our 4G LTE network delivered faster average download speeds than any of our competitors in PCWorld's most recent 13-market speed tests.

AT&T's 4G LTE network delivers speeds up to 10 times faster than 3G***, as well as multiple innovations that optimize the network for performance.  Our network's radio components are placed close to the antenna at most cell sites, instead of inside the base station, which helps minimize power loss between the base station and antenna and, in turn, improves the performance of our 4G LTE network. The network also is designed with its core elements distributed across the country, which helps reduce latency, or the delay when using the Internet, because your request isn't traveling as far.

AT&T's focus to deliver the best possible mobile Internet experience goes beyond 4G and DAS to embrace additional connection technologies.  AT&T operates the nation's largest Wi-Fi network**** including more than 31,000 AT&T Wi-Fi Hot Spots at popular restaurants, hotels, bookstores and retailers across the country.  Most AT&T smartphone customers get access to our entire national Wi-Fi network at no additional cost, and Wi-Fi usage doesn't count against customers' monthly wireless data plans.

Over the past five years, AT&T invested more than $115 billion into operations and into acquiring spectrum and other assets that have enhanced our wireless and wired networks. Since 2007, AT&T has invested more capital into the U.S. economy than any other public company.  In a July 2012 report, the Progressive Policy Institute ranked AT&T No. 1 on its list of U.S. "Investment Heroes."

Continuous processes around the development and deployment of applications are both impacted by -- and a benefit to -- the Internet of Things trend. To help better understand the relationship between DevOps and a plethora of new end-devices and data please welcome Gary Gruver, consultant, author and a former IT executive who has led many large-scale IT transformation projects, and John Jeremiah, Technology Evangelist at Hewlett Packard Enterprise (HPE), on Twitter at @j_jeremiah. The discussion is moderated by me, Dana Gardner, Principal Analyst at Interarbor Solutions.
With all the incredible momentum behind the Internet of Things (IoT) industry, it is easy to forget that not a single CEO wakes up and wonders if “my IoT is broken.” What they wonder is if they are making the right decisions to do all they can to increase revenue, decrease costs, and improve customer experience – effectively the same challenges they have always had in growing their business. The exciting thing about the IoT industry is now these decisions can be better, faster, and smarter. Now all corporate assets – people, objects, and spaces – can share information about themselves and thei...
Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
The Internet of Things is clearly many things: data collection and analytics, wearables, Smart Grids and Smart Cities, the Industrial Internet, and more. Cool platforms like Arduino, Raspberry Pi, Intel's Galileo and Edison, and a diverse world of sensors are making the IoT a great toy box for developers in all these areas. In this Power Panel at @ThingsExpo, moderated by Conference Chair Roger Strukhoff, panelists discussed what things are the most important, which will have the most profound effect on the world, and what should we expect to see over the next couple of years.
Discussions of cloud computing have evolved in recent years from a focus on specific types of cloud, to a world of hybrid cloud, and to a world dominated by the APIs that make today's multi-cloud environments and hybrid clouds possible. In this Power Panel at 17th Cloud Expo, moderated by Conference Chair Roger Strukhoff, panelists addressed the importance of customers being able to use the specific technologies they need, through environments and ecosystems that expose their APIs to make true change and transformation possible.
Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem" in this scenario: microservice A (releases daily) depends on a couple of additions to backend B (re...
Growth hacking is common for startups to make unheard-of progress in building their business. Career Hacks can help Geek Girls and those who support them (yes, that's you too, Dad!) to excel in this typically male-dominated world. Get ready to learn the facts: Is there a bias against women in the tech / developer communities? Why are women 50% of the workforce, but hold only 24% of the STEM or IT positions? Some beginnings of what to do about it! In her Day 2 Keynote at 17th Cloud Expo, Sandy Carter, IBM General Manager Cloud Ecosystem and Developers, and a Social Business Evangelist, wil...
PubNub has announced the release of BLOCKS, a set of customizable microservices that give developers a simple way to add code and deploy features for realtime apps.PubNub BLOCKS executes business logic directly on the data streaming through PubNub’s network without splitting it off to an intermediary server controlled by the customer. This revolutionary approach streamlines app development, reduces endpoint-to-endpoint latency, and allows apps to better leverage the enormous scalability of PubNub’s Data Stream Network.
The cloud. Like a comic book superhero, there seems to be no problem it can’t fix or cost it can’t slash. Yet making the transition is not always easy and production environments are still largely on premise. Taking some practical and sensible steps to reduce risk can also help provide a basis for a successful cloud transition. A plethora of surveys from the likes of IDG and Gartner show that more than 70 percent of enterprises have deployed at least one or more cloud application or workload. Yet a closer inspection at the data reveals less than half of these cloud projects involve production...
Apps and devices shouldn't stop working when there's limited or no network connectivity. Learn how to bring data stored in a cloud database to the edge of the network (and back again) whenever an Internet connection is available. In his session at 17th Cloud Expo, Ben Perlmutter, a Sales Engineer with IBM Cloudant, demonstrated techniques for replicating cloud databases with devices in order to build offline-first mobile or Internet of Things (IoT) apps that can provide a better, faster user experience, both offline and online. The focus of this talk was on IBM Cloudant, Apache CouchDB, and ...
Container technology is shaping the future of DevOps and it’s also changing the way organizations think about application development. With the rise of mobile applications in the enterprise, businesses are abandoning year-long development cycles and embracing technologies that enable rapid development and continuous deployment of apps. In his session at DevOps Summit, Kurt Collins, Developer Evangelist at, examined how Docker has evolved into a highly effective tool for application delivery by allowing increasingly popular Mobile Backend-as-a-Service (mBaaS) platforms to quickly crea...
I recently attended and was a speaker at the 4th International Internet of @ThingsExpo at the Santa Clara Convention Center. I also had the opportunity to attend this event last year and I wrote a blog from that show talking about how the “Enterprise Impact of IoT” was a key theme of last year’s show. I was curious to see if the same theme would still resonate 365 days later and what, if any, changes I would see in the content presented.
Cloud computing delivers on-demand resources that provide businesses with flexibility and cost-savings. The challenge in moving workloads to the cloud has been the cost and complexity of ensuring the initial and ongoing security and regulatory (PCI, HIPAA, FFIEC) compliance across private and public clouds. Manual security compliance is slow, prone to human error, and represents over 50% of the cost of managing cloud applications. Determining how to automate cloud security compliance is critical to maintaining positive ROI. Raxak Protect is an automated security compliance SaaS platform and ma...

We all know that data growth is exploding and storage budgets are shrinking. Instead of showing you charts on about how much data there is, in his General Session at 17th Cloud Expo, Scott Cleland, Senior Director of Product Marketing at HGST, showed how to capture all of your data in one place. After you have your data under control, you can then analyze it in one place, saving time and resources.
The Internet of Things (IoT) is growing rapidly by extending current technologies, products and networks. By 2020, Cisco estimates there will be 50 billion connected devices. Gartner has forecast revenues of over $300 billion, just to IoT suppliers. Now is the time to figure out how you’ll make money – not just create innovative products. With hundreds of new products and companies jumping into the IoT fray every month, there’s no shortage of innovation. Despite this, McKinsey/VisionMobile data shows "less than 10 percent of IoT developers are making enough to support a reasonably sized team....
Just over a week ago I received a long and loud sustained applause for a presentation I delivered at this year’s Cloud Expo in Santa Clara. I was extremely pleased with the turnout and had some very good conversations with many of the attendees. Over the next few days I had many more meaningful conversations and was not only happy with the results but also learned a few new things. Here is everything I learned in those three days distilled into three short points.
