Over Half the World Connected to the Internet

Over Half the World Connected to the InternetNew statistics show that over half of the world’s population is now using the Internet. The 2017 Q2 Global Digital Snapshot Report on social media and digital trends released by Hootsuite, a social media management platform, and We Are Social, a social media agency, found that more than 3.8 billion people around the world now use the internet. This means that global internet penetration is 51%. The report’s author flips the number and points out that people who don’t use the Internet are now in the minority.

How are these people getting online? The report says that the total number of unique mobile users now stands at 4.96 billion. The use of a mobile phone is now ‘normal’ around the world. Almost 66% of the entire global population regularly uses a mobile phone. More and more of these users now own a smartphone too, and the latest data suggest that more than half of the world’s population now uses one of these powerful devices.

The rapid spread of smartphones has led to significant growth in the number of mobile internet users. The number of people around the world accessing the internet via mobile reached almost 3.4 billion during early April 2017 according to the author.

Additionally, 93% of all internet users now go online via mobile devices (phones or tablets), and with the majority of new internet users now ‘phone first’, mobile’s share is likely to increase even more.

With all of this increased access, We are Social, writes that global social media users total to more than 2.9 billion users. This means that social media users are still increasing at a rate of more than 1 million per day – that’s 14 new users every second.

The article observes that mobile social media continues to see the fastest growth across all our key data points. In the past 3 months, mobile social media users grew by more than 1.6 million new users every day. The total number of people around the world accessing social media via mobile devices now stands at just under 2.7 billion, representing global penetration of 36%.

Where do all of these mobile social media users go? Of course, they go to Facebook (FB). The research says that Facebook dominates the social media world. The latest data suggests that the world’s favorite social platform adds more than a million new users every day.

Asia is the center of Facebook’s growth. Much of that growth came from India. With almost 250,000 new users in the country every day, the author speculates there’s a good chance that India will overtake the US to become Facebook’s most active market by July 2017.  Bangkok is Facebook’s most active city, with roughly 30 million people in Thailand’s capital using the platform.

It should be obvious to any marketer that firms need to remake their customer engagement plans and implement real-time interaction with their customers. Simon Kemp, We Are Social said.

“Half of the world’s population is now online, which is a testament to the speed with which digital connectivity is helping to improve people’s lives … Given this latest data, it’s probably time for us to stop referring to social as new media, and integrate it more seamlessly into our day-to-day activities.”

I think Mr. Kemp is too optimistic when he says that “digital connectivity is helping to improve people’s lives.” Followers of the Bach Seat know that too much social media is bad for you.

Limes in Your Data Center

Limes in Your Data CenterTimes are changing in the data center. For decades data centers were wired with orange multi-mode fiber optic cable. MMF is the choice for the data center connections because it is smaller and faster than copper and cheaper and more forgiving than single-mode fiber optic cables typically used for long-haul transmissions. The orange flavor of MMF was pulled into data centers to deploy Gigabit Ethernet.

multi-mode fiber optic cableThis type of MMF would work with links up to 600 meters. MMF uses the 850 nm and 1300 nm wavelength to transmit data. The typical MMF is 62.5/125 µm which means it has a core size of 62.5 micrometers (µm) and a cladding diameter of 125 µm, OM1 (“OM” stands for optical multi-mode). The second generation of MMF is 50/125 µm (OM2). These cables used LED transmitters. Newer installations often used laser-optimized 50/125 µm multi-mode fiber (OM3). MMF that meets this designation has enough bandwidth to support 10 Gigabit Ethernet (GigE) up to 300 meters.

10 GigE is a great technology, but many organizations have outgrown it. New variants of Ethernet can reach speeds of 25 Gbps, 40 Gbps, 100 Gbps, and soon, up to 800 GigE is needed to keep up with the new requirements of enterprise and cloud data centers.

cloud data centersThe industry determined that a new type of fiber was needed to physically pass the bits back and forth at these new speeds and yet maintain backward compatibility with older installations. In October 2016, the international cabling standards development body International Organization for Standardization/International Electrotechnical Commission (ISO/IEC) decided that the new standard would be called OM5.

Cabling Installation & Maintenance magazine reports that the new OM5 standard was developed to meet the increasing bandwidth demands but keep up compatibility with older MMF installations, “The standard specifies 50/125-micron laser-optimized fiber that is optimized for enhanced performance for single-wavelength or multi-wavelength transmission systems with wavelengths in the vicinity of 850nm to 950nm.”

OM5 fiber is 50 micron core, laser optimized multimode fiber (LOMF)Sr. Fiber Product Manager at Legrand Randy Harris, explained that OM5 fiber is a new type of 50-micron core, laser-optimized multimode fiber (LOMF) designed to provide better performance for applications using wavelength division multiplexing (WDM). It operates over a wider window in the range of 850nm to 953nm to support at least four wavelengths. Swiss-based cabling provider R&M says OM5 fiber-optic cabling supports duplex transmission by sending four wavelengths over a single multimode fiber to create future bandwidths up to 200 Gbps.

Cindy Montstream explained in an article published in Cabling Installation & Maintenance magazine in September 2016,

The 40 GE SWDM4 and 100 GE SWDM4 specifications support transmission over duplex OM3, OM4, and OM5 multimode fiber types. Maximum reaches vary from 75 to 440 meters depending on data rate and fiber type. The group added that in the future, SWDM technology could be leveraged to enable 200-, 400-, and 800-Gbit/sec Ethernet traffic on multimode fiber cabling as well.

In June 2016, a Telecommunications Industry Association (TIA) TR-42 subcommittee approved the new standard, which specifies wideband multimode fiber. In February 2017, the TIA TR-42.12 Optical Fibers and Cables subcommittee approved lime green as the OM5 jacket color. At that time it also approved a project to develop Addendum 2 to the TIA-598-D standard.

The evolution of Ethernet is driving changes in the data center. The IEEE has developed a couple of new standards for Ethernet, which I wrote about here. The new standards include IEEE 802.3by, which covers 25 Gb/s switch interconnects for data centers.

In well-done cable installations cables can be distinguished by jacket color:

  • Orange jackets indicate legacy 62.5/125 µm (OM1) and 50/125 µm (OM2) fiber-optic cabling
  • Aqua jackets show 50/125 µm “laser-optimized” OM3 and OM4 fiber fiber-optic cabling
  • Lime-green jackets  50/125 µm “laser-optimized” OM5 fiber-optic cabling
  • Yellow jackets indicate single-mode fiber-optic cabling

It took decades to install all the orange old-school MMF, it is going to take several more decades to get it all uninstalled.

Who Owns Ruckus Today?

Updated December 05, 2017 – As predicated below, cable box maker, ARRIS International completed its acquisition of Ruckus Wireless from Broadcom in December 2017. According to reports, “Ruckus Networks, an ARRIS company,” will operate as a dedicated business under the ARRIS Enterprise Networks business segment.

Who Owns Ruckus Today?Ruckus Wireless was founded in 2004 and supplied Wi-Fi services and equipment to enterprises and service providers. At its peak, it had annual revenues of almost $400 million and more than 1,000 employees. Ruckus was the first firm to roll out enterprise 802.11ac Wave 2 AP. The company’s products powered high-profile public Wi-Fi installations, such as New York City’s LinkNYC.

Ruckus WirelessIn April 2016, San Jose, CA-based Brocade purchased Ruckus Wireless in a deal worth about $1.5 billion. Brocade is most famous for data center SAN switches and a player on the NFV and SDN scene. Brocade planned to add Ruckus’s Wi-Fi products to its enterprise networking business.

At the time of the purchase, Brocade CEO Lloyd Carney said, “The acquisition will strengthen Brocade’s ability to pursue emerging market opportunities around 5G mobile services, Internet of Things (IoT), Smart Cities, OpenG technology for in-building wireless, and LTE/Wi-Fi convergence.

Brocade Networks logoRuckus changed hands. Irvine, CA-based chipmaker Broadcom (AVGO), which supplies to phone vendors purchased Brocade for $5.9 billion. But the chipmaker said it plans to divest the Brocade IP networking business that consists of wireless networking, data center switching, and software networking offerings.

Brocade CEO Lloyd Carney wrote on the company’s website. “In terms of our IP Networking business, due to competitive overlap with some of Broadcom’s most important customers, Broadcom will seek a buyer for the business.” The Ruckus product line competes with industry titans like Cisco and Apple.

BroadcomBroadcom logo CEO Hock Tan said in a press release, “… we will find a great home for Brocade’s valuable IP networking business that will best position that business for its next phase of growth.” It seems Broadcom has found a firm willing to take Ruckus off their hands.

FierceCable is reporting that cable set-top box manufacturer Arris (ARRS) is in talks with Broadcom to pay around $1 billion for Brocade’s wireless network edge business – i.e Ruckus Wireless. The article says Arris CFO David Potts told investors that the vendor might transition into serving the wireless needs of its customers. Arris client, Comcast is developing a wireless service based on its MVNO relationship with Verizon.

Arris logoReports are that Arris does not want to buy other parts of the business being divested by Brocade. Brocade is reportedly looking for a buyer for the rest of its IP portfolio, which includes data centers, switching, and software.

Linux Turns 25

Linux Turns 25Linus Torvalds released the first Linux operating system kernel on Oct. 5, 1991. On Oct. 6, 1991, Torvalds began arguing with volunteer developers who would go on to make Linux an open-source powerhouse and eventually a household name. Today the Linux community is upwards of 86 million users strong.

Linux Turns 25As part of celebrations to mark Linux’s 25th birthday the Linux Foundation has published its annual Linux Kernel Development Report (PDF reg required). According to the Register, the report concludes that Linux is in great shape, “There may be no other examples of such a large, common resource being supported by such a large group of independent actors in such a collaborative way.”

The independent actors have a lot to collaborate on. The report notes that the first versions of the Linux kernel comprised about 10,000 lines of code. Now it’s nearing 22 million and growing at a rate of 4,600 lines a day.

Wall StreetWhile Linux may have started out as a hobby OS, that changed in the early 2000s. At the turn of the century, Wall Street banks demanded Linux support for their enterprise application servers says Tech News World.

“That was a moment that broke down resistance to Linux in the big IT vendors like BEA, IBM, and Oracle (ORCL). That hole in the dam was the start of a flood,” said Cloud Foundry CEO Sam Ramji. “Today Linux is the home of operating system innovation.

Linux user and open source advocateAporeto Virtualization Expert Stefano Stabellini, who has been a Linux user and open source advocate since the 1990s explained the transition. “… back when I started with Linux in the ’90s … [companies] did not understand it. They thought that open source was unsustainable, and Linux was niche and hobbyist.” He says that now everything has changed. Every company has an open source strategy now. “Microsoft (MSFT) was the biggest foe and now is a strong ally. Linux is the most widely adopted operating system of all times.

Dice points out that the most active contributors to the growth of Linux have included (in descending order) Intel (INTC), Red Hat, Linaro, Samsung (005930), SUSE, IBM (IBM), and various corporate consultants. Google (GOOG), AMD (AMD), and Texas Instruments (TXN) also ranked in the top 15.

So my first pass at Linux was Red Hat Linux 5.0. when Novell bought into Linux. Yeap I was a Novell CNE 5 way back in the day.

The last couple of projects I have been involved with have used Linux and not Windows, CMS, IVR, PAFW’s, and storage.

AT&T Tries Broadband over Powerline

AT&T Tries Broadband over PowerlineIt’s alive. It’s alive! BPL has risen from dead. Longtime readers of the Bach Seat, know the history of Broadband over Powerline. I covered it many years ago here, here, and here. Imagine my surprise when there were a number of articles popping up all over the interwebs touting mega-telecom AT&T’s (T) try at BPL 10 years after everybody else gave up on the technology.

Broadband over PowerlineComputerWorld described this latest incarnation of BPL from AT&T as a low-cost, high-speed wireless internet technology. This time Broadband over Powerline relies on plastic antennas positioned along medium-voltage power lines and not through the conductive materials inside the power lines. FierceTelecom says that AT&T will attach the plastic antennas to the power lines and serve as a mesh network to distribute signals to homes and businesses. The Project AirGig low-cost plastic antennas and devices will regenerate millimeter wave (mmWave) signals. Millimeter-wave technology relies on electromagnetic waves that are longer than x-rays but shorter than radio waves (they are found in the 10 mm to 1 mm range and are also known as extremely high-frequency waves according to New Atlas. The EHF waves can be used for 4G LTE and 5G multi-gigabit mobile and fixed deployments.

John Donovan, chief strategy officer and group president of AT&T technology and operations, told FierceTelecom that Project AirGig delivers last-mile access without any new FTTH technology and is flexible enough to be configured with small cells or distributed antenna systems.

Broadband over PowerlineTo test the technology, AT&T is looking for a place somewhere in the next year with a favorable regulatory environment, since the carrier would need to partner with an existing electric utility. John Donovan, chief strategy officer for AT&T said the trial could be in an area where existing broadband is expensive, even in the U.S.

The AirGig project relies on over 100 patents, according to an AT&T statement. There is no direct electrical connection to the power lines, although network components could receive their needed power through inductive wireless electricity from the near by power lines, AT&T Chief Technology Officer Andre Fuetsch explained to Computerworld.

ATT logoAT&T said the testing will decide what frequency AirGig will use for commercial deployment, which could occur sometime around 2020 after the carrier rolls out 5G wireless. The frequency AT&T uses will affect the range of the signal and the speed, as well as whether it is over a licensed or unlicensed band. This decision is important if AT&T plans to use BPL as another weapon in its fight with Google Fiber. Earlier versions of Broadband over Powerline were incapable of delivering the Google (GOOG) promised Gigabit of Internet access.

“It’s a transformative technology that delivers low-cost and multi-gigabit speeds using power lines,” AT&T’s Donovan said, “There’s no need for enhancements for new towers, and it’s over existing infrastructure.”

Google (GOOG) promised Gigabit of Internet accessAirGig has already been tested in outdoor locations on-campus settings. “We’ve had it up and running 4k video and cameras on campuses for quite some time,” Mr. Donovan said.

Besides using the AirGig technology as an alternative broadband service delivery option, for urban, rural, and under-served markets AT&T wants to convince the electrical utility industry to apply AirGig technology to their unique needs. ComputerWorld says utility companies would be able to use the technology to help spot problems on their power lines from something like a downed tree or cracks in the cable sheath.

New Atlas points out that earlier this year, a millimeter-wave technology system set a new world record for wireless data transmission by sending data at 6 Gbps. The technology is also showing up in other applications, including heart-rate monitors, car-safety systems, and luggage scanners.

AirGig could be profitable for AT&T. If they can make a deal with an electrical company, they can avoid expensive make ready. Which Google Fiber is struggling mightily with. By using power lines, AirGig avoids the cost of digging trenches to lay fiber optic cable.

Still, questions remain about how this version of Broadband over Powerline will do in the real world.

  • What impact will heavy rain, snow or ice have on the signal?
  • What if a tree branch falls on a power line or the lines are swinging in the wind?
  • Since mmWave transmissions need a direct line-of-sight between antennae, what happens when critters like birds or squirrels decide to perch on the antennae? Will that lead to an outage?

The ham radio lobby will likely be up in arms again when they find AT&T still likes the idea of BPL in the 30-300 GHz bands. The ARRL was a key player in killing BPL 1.0.
