Your world is about to change. 5G is coming. Whether you are a wireless carrier, a handset maker, an app developer, a mobile TV provider, a worker, investor or consumer, your world is about to undergo a major transformation. AT&T recently announced plans to start testing 5G technology this year. Wireless data transmissions could be 10 to 100 times faster over 5G than on current 4G networks.

AT&T on Friday announced plans to start testing 5G technology, with a possible limited commercial rollout before the end of 2016. 5G offers the promise of besting the speeds of today's fastest wireless networks by a factor of 10 to 100, through the use of millimeter waves, network function virtualization, and software-defined networking. AT&T is collaborating with Ericsson and Intel on the effort.

T-Mobile's 700-MHz rollout has given its mobile users some of the fastest data speeds in the U.S. market, according to a report OpenSignal released Tuesday. OpenSignal crowdsources data on carrier signal quality from users who have its consumer mobile application installed. T-Mobile has the fastest 4G LTE download speeds in the country, overtaking Verizon by a slight edge.

T-Mobile's Binge On streaming video service violates Net neutrality rules, according to a report authored by Barbara van Schewick, director of The Center for Internet and Society at Stanford Law School. Among the reasons the Binge On service may be problematic: It doesn't offer unlimited video streaming, raising transparency concerns; and it gives participants a competitive advantage.

Sprint plans to lay off about 2,500 employees, including five vice presidents, according to news reports this week. About 2,000 of the cuts are in customer service. The company reportedly will close or reduce operations at six customer care centers: at its Overland Park headquarters in Kansas and in Colorado, New Mexico, Tennessee, Texas and Virginia.

AT&T on Tuesday began offering unlimited mobile data to its pay TV customers. New or existing DirecTV and U-Verse TV subscribers can get unlimited talk, text and data for $100 per month. AT&T will charge $40 for two additional phones, and a fourth phone will be free. Subscribers can add smartwatches and certain connected devices to their unlimited plans for $10 per device.

John Legere, T-Mobile's loquacious CEO, has apologized to the Electronic Frontier Foundation for what he described as a "color commentary" that drew sharp criticism. "I am a vocal, animated and sometimes foul mouthed CEO," Legere wrote in a blog post. "I don't filter myself and you know that no one at T-Mobile filters me either." Legere offered a mea culpa for "offending EFF and its supporters."

T-Mobile last week introduced its latest promotion aimed at attracting subscribers from rival mobile phone carriers: 12 months of Hulu streaming service for Verizon customers who switch to T-Mobile. In addition to a year's worth of Hulu service, T-Mobile will give Verizon customers who switch up to $125 off in-store accessories such as smartwatches, speakers, fitness trackers and headphones.

T-Mobile on Wednesday announced Binge On, a plan that lets qualified customers Netflix and chill as much as they want. It's the type of move meant to shake up the wireless industry and to cultivate more T-Mobile loyalists. Beginning this Sunday, certain customers can consume streaming content from several popular services without having it count against their data plans.

Karma Mobility last week unveiled Neverstop, an all-you-can-eat data plan for its mobile hotspot. There are no data caps, and the service, which runs on Sprint's 4G LTE network, is available in more than U.S. 450 cities. For $50 a month, customers get unlimited data minutes at speeds of up to 5 Mbps for both downloads and uploads. When LTE isn't available, the hotspot runs at CDMA speeds.

Nokia will test Artemis Networks' pCell technology, which promises speed boosts in bounds for wireless broadband without requiring new handsets, the companies announced Monday. Nokia plans to work with wireless carriers to test the technology in the U.S. and other countries starting in 2016. It has entered into a memorandum of understanding on pCell tech with Rearden, parent company of Artemis.

Rumors that T-Mobile plans to introduce an unlimited data plan for streaming video services circulated Thursday following a Twitter post from journalist Evan Blass, who tweets under the handle @evleaks. The company would allow unlimited high-speed data to be used to watch select streaming from services such as Netflix and HBO under its "Uncarrier 10" campaign, he suggested.

Project Loon, part of Google's parent company, Alphabet, on Wednesday announced that it has signed agreements with three mobile network operators in Indonesia -- Indosat, Telkomse, and XL Axiata -- to begin tests of its balloon-powered Internet service in 2016. Only about one in three of Indonesia's 250 million residents is connected to the Internet, according to Project Loon.

The European Parliament on Tuesday passed Net neutrality legislation to a chorus of boos from Net neutrality proponents. The European Union has found consensus on the common principles of Net neutrality -- no blocking, no throttling and no prepaid prioritization -- said Commissioner Günther H. Oettinger. However, the rules have three major loopholes, Net neutrality supporters said.

Verizon has announced it will begin sharing customer data with its AOL Advertising Network, triggering concerns about privacy and customer tracking. AOL will use Verizon's supercookie -- which is difficult to get rid of -- to track users. "This is a huge privacy problem, but carriers have never really cared that much about customer satisfaction," said tech analyst Rob Enderle.

Instead of bidding for the low-band spectrum that will be on offer, Sprint -- which is running neck-and-neck with T-Mobile, the self-styled "Un-Carrier" -- will focus on improving its network. It could be the last low-band auction the industry sees for decades, T-Mobile CEO John Legere said this summer. Up for grabs at the next auction are 600-MHz bands.

Putting this burning issue on the front page is great. Everyone should know the problems caused by wireless data thieves. The reason is simple. Data hogs are threatening to spoil things for everyone. Yes, that means for you and your business. Data hogs threaten T-Mobile's growth because they spoil things for regular wireless data users. This is also a larger problem for the entire industry.

Verizon is accelerating its efforts to boost wireless connections to 50 times faster than current offerings. The company has begun putting the components in place to enable it to begin field testing a new, speedier wireless technology, known as "5G," next year. "5G is no longer a dream of the distant future," said Roger Gurnani, chief information and technology architect for Verizon.

Sprint last week announced it was celebrating the AT&T/DirecTV merger by extending a truly valuable offer to DirecTV customers. "The Sprint network is winning awards across the country for reliability and speed, and our customers have never been more satisfied," crowed Sprint spokesperson Kristin Wallace. "We are simply giving DirecTV customers a compelling reason to experience Sprint."

CEO John Legere has publicly declared war on data hogs who threaten to ruin T-Mobile for regular consumers. "This week I am taking aim at a select group of individuals who have actually been stealing data from T-Mobile," he wrote. "If their activities are left unchecked, their actions could eventually have a negative effect on the experience of honest T-Mobile customers. Not on my watch."

It appears both AT&T Mobility and Sprint deserve congratulations on their great performances, based on two just-released studies on the wireless wars. J.D. Power and RootMetrics revealed some interesting and surprising new information on this changing marketplace. For the fifth time, AT&T won first place with J.D. Power. For its part, Sprint showed significant performance improvement over the last year.

The National Security Agency considered its relationship with AT&T unique and particularly productive, accordingto a report published Saturday. The information about the company's close ties with the agency came from the trove of documents released by NSA whistleblower Edward Snowden. NSA lauded AT&T for its "extreme willingness to help," giving it access to billions of emails among other things.

Sprint continued to make progress in its turnaround during Q1, it said Tuesday. However, it apparently wasn't enough to keep the company from slipping to fourth place among major wireless carriers, exchanging places with T-Mobile, which climbed up to third. Among other things, Sprint cut postpaid customer losses in the quarter to 12,000 -- the lowest ever.

AT&T's acquisition of DirecTV is more than a merger -- it is a transformational event that could change the entire television space. It has the potential to create such intense competition that it very well could transform the entire television space -- meaning cable TV, satellite TV and IPTV -- and blend it with wireless. It means more choice and more innovation.

Apple is in discussions to become a mobile virtual network operator in both Europe and the United States, where it's already running a trial of its service, according to a media report. The MVNO idea may not advance beyond the test phase -- and if it does, it likely won't happen for some time -- at least five years. However, Apple on Tuesday issued a denial that it has held MVNO discussions.

AT&T on Monday announced its first-ever nationwide package of TV and wireless services. The new bundle, which is being offered for US$200 per month, will be available beginning Aug. 10. It will include HD and DVR service for up to four TV receivers, along with unlimited talk and text for four wireless lines. Subscribers to the plan will get 10 GB of shareable wireless data.

We have just seen quarterly earnings reports from AT&T and Verizon, and they continue to grow at a healthy pace. Sprint and T-Mobile also have started to grow once again. However, the larger wireless marketplace is splitting into smaller segments. Understanding this is one of many keys to success for any wireless carrier going forward. The larger wireless marketplace is changing.

Sprint's Direct 2 You program seems to be another home run in its recovery-and-expansion effort. It follows the success of Sprint's Cut Your Bill in Half plan over the last few months. Direct 2 You started out in Kansas City, Miami and Chicago. It is now in 28 cities and expanding rapidly. Sprint just announced its expansion into New York, Los Angeles, San Francisco and Denver.

An Electronic Frontier Foundation survey published last week gave AT&T, Verizon and WhatsApp the thumbs down when it comes to protecting user privacy. Google and Twitter also got a black eye. The five were among 24 companies the EFF evaluated on criteria worked out over the past four years. WhatsApp, now owned by Facebook, also took criticism in the EFF's fifth annual report, "Who Has Your Back?"

There seem to be two distinct sectors forming in the wireless industry. One side is wireless as part of a bundle of services. The other is wireless as a standalone product. This is not a case of one side being a winner and the other a loser -- they're just different. The rules for success seem to be changing as well. That means how we measure and track companies on both sides may have to change.
