Without dramatic changes in wireless pricing and more careful usage, owning a smartphone will cost an average of $119 a month per phone by the year 2019.

Ever since the largest players in the wireless industry decided to monetize wireless data usage by ending unlimited use data plans, the average monthly phone bills of smartphone users have been on the increase. In 2013, the average cell phone bill was $76 a month, according to Bureau of Labor statistics. That’s up 50% from the $51 a month customers paid in 2007, the first year the iconic Apple iPhone was offered for sale.

Although wireless companies claim their current 4G (largely LTE) networks are robust enough to sustain the growing demand for wireless data until more spectrum becomes available, the transition to next generation 5G technology will dramatically increase the efficiency of wireless data transmission, delivering up to 40 times the speed of existing 4G networks. But if providers are not willing to slash prices on 5G data plans, average usage and customers’ phone bills are likely to soar to new all-time highs, costing a family of four smartphone owners an average of $476 a month.

A study by Wafa Elmannai and Khaled Elleithy at the Department of Computer Science and Engineering at the University of Bridgeport found wireless carriers have given up on monetizing voice and texting services, including unlimited minutes and text messages as part of most basic service plans. The real money is made from wireless data plans which traditionally cost customers between $10.79-16.72 per gigabyte, depending on the carrier and whatever fees, surcharges and required add-ons are necessary to get the service.

Wireless carriers defend their pricing, claiming they have cut prices on certain data plans while granting some customers extra gigabytes of usage at no extra cost. Some evidence shows that carriers have indeed reduced the asking price of delivering a megabyte of data by 50 percent annually. But their costs to deliver that data have dropped even faster, particularly as networks shift traffic away from older 3G networks to 4G technology, which is vastly more efficient than its predecessor.

The end of unlimited data plans by AT&T and Verizon Wireless was key to shifting the industry towards monetizing data usage. The more a customer consumes, the more revenue a carrier earns. But as web pages and applications become more complex and bandwidth intensive, customers will naturally consume more and more data each month, forcing regular usage plan upgrades to avoid confronting overlimit fees. Unless providers pass along more of their savings on traffic costs to consumers, bills will rise.

At current usage estimates from Cisco, the average customer will consume at least 57% more wireless data by 2019 than they do today. To sustain that usage, wireless providers are bidding for additional spectrum rights and are working towards upgrading to next generation 5G technology. But some carriers, including AT&T and Verizon, are also investing in new applications for their networks that include in-car telematics, home security and automation, and online video. Using some of these technologies guarantees an even greater amount of data usage, particularly for online video. Unless customers are careful about their usage and avoid high-bandwidth applications, they are in for a much bigger bill in the future, much to the delight of wireless providers.

While most analysts expect wireless companies will choose to give customers a larger data allowance instead of resorting to fire sale pricing, Elmannai and Elleithy expect that will not be enough to keep cell phone bills stable.

“We will need to reduce the bit rate to (1/1000th) of today’s level in order to receive x1000 of data capacity [at the] same cost [we see today],” the authors conclude. That would mean a low end 1GB data plan on a 4G network would cost just $0.03. Larger allowance plans would cost less than one cent per gigabyte.

The authors of the study expect carriers to price 5G data plans more or less the same as 4G plans, but will probably boost usage allowances to deliver a perception of greater value. But as web applications continue to gravitate towards higher data usage, bills will continue to rise, assuring providers of growing returns even with modest to moderate levels of competition.

At the moment, despite some evidence of price competition, some carriers are still raising prices. Verizon increased the price of its 10GB plan by $20 to $100 a month and T-Mobile raised the price of its unlimited data plan by $10 a month last year.

The CTIA is the wireless industry’s lobbying group

The wireless industry is threatening to withhold upgrades to 5G service unless the United States adopts a spectrum policy that provides wireless carriers with more frequencies.

CTIA president Meredith Baker told attendees at the Accenture conference that the wireless industry wants a new national spectrum plan to clear more frequencies for the exclusive use of mobile providers.

“When and how we introduce 5G in the United States depends, in part, upon whether we keep our spectrum policy as forward-looking as our industry,” Baker said. “The question we face is will the U.S. continue to embrace licensed spectrum – the approach that has made us the global leader in 4G.”

Baker is frustrated with the FCC’s ongoing effort to create “shared-use” spectrum that can be cleared for mobile use in certain sections of the country while still being used for other purposes elsewhere. In some cases, spectrum identified for possible dual-use is used by various government agencies, but only in certain parts of the country. The wireless industry generally does not favor shared-use spectrum policy because it can complicate wireless network buildouts.

Baker

Baker continues to advocate a more forceful approach of “spectrum clearing,” which can force users off existing frequencies to clear it for mobile exclusivity.

“Clearing spectrum will never look easy, particularly years before an auction,” she said. “To be fair, it will never be easy. But it can be done and needs to be done if we are to remain the global leader in mobility.”

The FCC is currently involved in an effort to repack the UHF television dial into a smaller space to make room for more spectrum for the wireless industry. Some companies, notably AT&T, are growing impatient about the process and want faster exclusive use of those frequencies after an incentive auction is held in 2016.

In a filing sent to the FCC, AT&T objects to creating more spectrum rights for secondary and unlicensed users and applications on the frequencies they intend to use. Once the auction is complete, it could take three years or more for AT&T and other spectrum winners to upgrade their networks to use the new frequencies in the 600MHz band. In the meantime, the FCC has proposed allowing low-power television stations and translators, wireless microphones, and other similar unlicensed equipment to continue using those frequencies until the new license holders are ready to become operational.

AT&T considers that an intrusion on its spectrum and has told the FCC it strongly objects allowing any secondary or unlicensed user to use their spectrum “without so much as [paying AT&T] a lease” or getting consent from AT&T. AT&T wants everyone off their frequencies no later than 39 months after the issuance of a Channel Reassignment Public Notice that will identify new channel assignments for full power and Class A television stations that have been reassigned to different channels. AT&T also wants the right to jump ahead of the proposed three years of transition for licensed stations and make it possible to start kicking off all unlicensed users of its frequencies within 120 days notice.

The wireless industry argues without wireless-friendly policies, there will be insufficient incentive to invest in 5G network upgrades.

Critics contend that is just another of the wireless industry’s empty threats. Opponents contend AT&T will invest in network upgrades the moment the company believes it will generate additional profits.

With billions of dollars in new revenue and royalties to be made, Qualcomm and some members of the wireless industry are pushing regulators to quickly approve a new version of LTE wireless technology that will share many of the same frequencies used by home and business Wi-Fi networks, creating the potential for speed-killing interference.

Wireless operators believe LTE-Unlicensed (LTE-U) could be used to offload much of the growing wireless data traffic off traditional 4G LTE wireless data networks. With the cost of securing more wireless spectrum from regulators growing, LTE-U technology would allow operators like AT&T, Verizon, Sprint and T-Mobile to use the U-NII-1 (5150-5250MHz) and U-NII-3 (5725-5850MHz) unlicensed bands currently used for Wi-Fi to deliver high-speed wireless broadband traffic to their customers.

Qualcomm and Ericsson, behind the newest iteration of LTE, have a vested interest promoting it as the ideal choice for metrocell, indoor enterprise, and residential small cell applications. Every manufacturer incorporating LTE-U technology into everything from carrier-owned microcells to smartphones will owe royalty payments to both companies. With billions at stake, Qualcomm is doing everything possible to tamp down fears LTE-U signals will create harmful interference to Wi-Fi signals.

At the Consumer Electronics Show in Las Vegas held in January, a Qualcomm representative went as far as suggesting LTE-U will improve home Wi-Fi service. (5:42)

RCRWireless News:

[Qualcomm] set up a screened room with eight pairs of access points occupying the same channel and added Wi-Fi access-point terminals in one room and LTE-U terminals in another. The results show the average throughput of 3.3Mbps with Wi-Fi alone more than doubled to 6.7Mbps when the LTE-U access point was introduced.

In another test to show that LTE-U is a better neighbor to Wi-Fi than Wi-Fi itself, they took eight Wi-Fi nodes and replaced four of them with LTE-U nodes, the result of which showed a 1.9Mbps increase in average Wi-Fi throughput. In almost every test, the LTE-U enhanced network outperformed traditional Wi-Fi.

Burstein

Industry observer Dave Burstein is concerned advocates of LTE-U are trying to rush approval of the technology without verifying Qualcomm’s non-interference claims.

“The telcos are considering 40 and 80MHz channels that could easily swallow half of more of the Wi-Fi spectrum,” Burstein writes in response to an EE Times article about the technology. “If Wi-Fi is important, that’s a mistake to allow. Advocates are trying to rush it through even though there is not a single independent test or field trial.”

Qualcomm dismisses the interference complaints pointing to its own research showing the two standards can co-exist adequately. But multi-billion dollar wireless companies with nationwide Wi-Fi networks at stake are far less confident. In fact, LTE-U has already divided the two largest wireless carriers in the United States. Verizon Wireless is an original proponent of LTE-U while AT&T has expressed “concern,” a polite way of saying it isn’t happy. What separates AT&T and Verizon Wireless? AT&T has invested in a nationwide network of more than 34,000 Wi-Fi hotspots. Verizon offers just over 5,000, most for FiOS customers or those in especially high traffic venues.

A Stanford University professor with no ties to Qualcomm or the wireless industry privately shared his belief allowing 5GHz Wi-Fi signals to commingle with LTE-U is going to cause problems.

The development of “Wild West” Wi-Fi has always tracked differently than the licensed cellular/wireless business. Over more than a decade, evolving Wi-Fi standards have come to expect interference from other nearby Wi-Fi signals. In a densely packed city, more than two dozen Wi-Fi signals can easily be found all competing for their own space across the old 2.4GHz and newer 5GHz unlicensed bands.

Wi-Fi proponents credit its robustness to its “politeness protocol.” Before a wireless router or home hotspot fires up its Wi-Fi signal, it performs several tests to check for other users and constantly adjusts performance by backing off when it discovers interference from other signals. That is why a user can receive strong Wi-Fi signals but still endure reduced performance, as the hotspot accommodates nearby hotspots and other traffic.

It works reasonably well, according to Rupert Baines, a consultant at Real Wireless.

“But [Wi-Fi signals] are delicate, and they rely on implicit assumptions that there aren’t other things there (or aren’t too many),” Baines told EE Times. “In effect, they behave as though the unlicensed band were not technology neutral but were Wi-Fi only.”

The intrusion of LTE-U changes everything.

[flv]http://www.phillipdampier.com/video/Wireless Week Tuesdays with Roger LTE-Us Gain is Wi-Fis Loss 3-24-15.flv[/flv]

On the March 24, 2015 episode of Tuesdays with Roger, Recon Analytics’ founder Roger Entner talks with Wireless Week about the questions raised as major carriers, including T-Mobile and Verizon Wireless, plan to launch LTE into unlicensed territory. Concerns abound, particularly for consumers and companies who rely on Wi-Fi and don’t want licensed use in unlicensed bands to interrupt that service. (7:31)

Change in and of itself is not necessarily a bad thing, especially if LTE-U is superior to Wi-Fi, and some proponents suggest it is. Jag Bolaria, an analyst at The Linley Group, argues LTE better manages data/call handoff better than Wi-Fi access points can. LTE is also a more efficient spectrum user than Wi-Fi.

Last week, South Korea’s LG U+ demonstrated LTE-U was capable of 600Mbps speed, eight times faster than traditional LTE. But to accomplish that level of speed, LG U+ had to occupy 60MHz of bandwidth in the 5.8GHz band and allocate an extra 20MHz from its traditional LTE service. The company plans to further expand its use of South Korea’s 5.8GHz unlicensed band by occupying 80MHz of it to further boost speeds to 750Mbps. But the company did not say how the tests affected others sharing the same frequencies.

If LTE-U is superior, then why not gradually move every user towards the technology and away from Wi-Fi?

Aptilo Networks AB CEO Torbjorn Ward answers LTE-U is a solution in search of a problem.

“I think LTE on unlicensed sounds like a good idea if it wasn’t for the fact that there are four billion devices on Wi-Fi out there,” he told Light Reading, noting that 802.11ac can already run at 100Mbps, so there’s little need for the LTE boost. “I think when it comes to unlicensed, you can do a longer range with LTE, but I don’t see the full benefit.”

That does not seem to matter to LTE-U’s developers or cell phone companies that lack robust Wi-Fi networks of their own.

In the original Qualcomm/Ericsson proposal, both companies promote the fact they could launch LTE-U in the unlicensed Wi-Fi bands “as-is.” That is a big problem for AT&T and other Wi-Fi users because LTE-U evidently employs few, if any protection protocols in its initial specifications for other traffic. Verizon Wireless is reportedly lobbying against the development of interference protection protocols and has publicly asserted its interest in deploying LTE-U regardless of other users.

“In [the] USA, there are no requirements for unlicensed deployment that require changes to LTE air interface,” Verizon stated in its proposal: “New Band for LTE deployment as Supplemental Downlink in unlicensed 5.8GHz in USA.”

LTE-Unlicensed has been characterized as “rude” for not avoiding interference to other users.

Clint W. Brown, business development director of mobility wireless connectivity at Broadcom, and a vice-chairman of the Wi-Fi Alliance counters it is premature to approve LTE-U in the unlicensed Wi-Fi band without more testing and information about its interference protocols.

“We’ve heard about the tests they’ve done, but it’s not factual,” Brown told EE Times. We haven’t seen the data and we don’t know how the tests were set up. First, I’d like to see if [LTE-U] can detect low-level signals. Second, I want to make sure it features a ‘Listen before Talk’ decision process so that LTE-U will wait for an opening rather than barging into the conversation already taking place in the unlicensed spectrum. Third, there should be a back-off mechanism, when it sees a collision. “We aren’t aware of any publicly available documents explicitly stating those attributes.”

The Federal Communications Commission has also now taken an interest and issued a public notice asking stakeholders and consumers to share their thoughts on LTE-U and a companion technology known as Licensed Assisted Access (LAA) that would hand off data sessions between a wireless carrier’s traditional 4G LTE network and LTE-U.

The makes the discussion political as well as technical. The FCC traditionally permits industry groups to define standards, but Republican Commissioner Mike O’Rielly now worries the FCC might butt into that process.

“The decision to jump into this space rather casually causes me great concern,” O’Rielly said. “In particular, any step that could insert the commission into the standards work for LTE-U comes with great risk. I will be vigilant in ensuring that the commission’s involvement does not result in taking sides with various stakeholders, hindering technological innovation, or having any say about what technologies should or should not be deployed.”

For the moment, O’Rielly’s concerns about the FCC are premature as long as a division exists over LTE-U among many of the industry players:

• Companies FOR LTE-U: Verizon, China Mobile, Qualcomm, Ericsson, NTT DoCoMo, T-Mobile USA, Deutsche Telekom, TeliaSonera, and China Unicom.  Equipment manufacturers also in support: Nokia, NSN, Alcatel-Lucent, LG, Huawei, ZTE, Hitachi, Panasonic, and others;
• Companies AGAINST LTE-U (as now defined): Orange, Telefónica, Vodafone, AT&T, Sprint, SouthernLINC, US Cellular, DISH and a handful of vendors.

Burstein also uncovered evidence the wireless industry may be stacking the deck against increased competition and consumers. He found 11 of the world’s largest wireless companies (including AT&T, T-Mobile, and Sprint) quietly colluding on a proposal that would block anyone other than currently licensed LTE users from being able to use LTE-U on a standalone basis. The opaquely-titled proposal, “Precluding standalone access of LTE on unlicensed carriers,” is at least frank about its reasoning: “Standalone deployment in unlicensed spectrum implies drastically different business models from nowadays and might impact the value chain.”

In other words, if consumers are able to get savings from LTE-U using a new generation of non-traditional providers like Republic Wireless or Cablevision’s Freewheel that do not depend primarily on cellular networks, it could cost those 11 traditional wireless companies billions in lost revenue. To stop that, the companies propose requiring a special LAA “guard signal” to stop standalone access of LTE-U. Since only licensed cell phone companies have access to those frequencies, it automatically locks out new upstarts that lack mobile spectrum of their own.

Sneaky insertions like that may be exactly why the Obama Administration’s FCC is being more activist about monitoring the wireless industry, potentially cutting off anti-competitive proposals before they can become adopted as part of a formal technical standard.

RCRWireless News gets deep into the development of LTE-Unlicensed and how it will impact cellular infrastructure, Wi-Fi and small cells. (25:39)

A Verizon executive told investors there is no wireless spectrum shortage in the United States and Verizon has historically purchased and warehoused spectrum it had no intention of using immediately.

Fran Shammo, chief financial officer of Verizon Communications, drew attention to Verizon’s controversial spectrum acquisition policy as part of a conversation with investors about the recent FCC auction that sold 65 megahertz of wireless frequencies for an unprecedented $44.9 billion, far and away the highest ever seen in a spectrum auction.

“In every purchase of spectrum up to this auction, the scale was that it was more efficient to buy spectrum than it was to build capacity because the scale was spectrum was cheaper to build on capacity,” Shammo said.

Before the auction, there were significant differences in Verizon Wireless’ network capacity in different cities. In New York City, Verizon controls 127MHz. In Los Angeles and San Francisco it manages with 107MHz, but only has 97MHz to work with in Philadelphia, San Diego and Chicago.

Verizon Wireless has always held spectrum it acquired at auction but never put into widespread use on its network. But bidding during the FCC’s most recent Auction 97 made bidding and warehousing unused frequencies an expensive proposition, more expensive than beefing up Verizon’s existing network with additional cell towers, microcells, and other technology to make the most use of existing spectrum assets.

“This auction flipped [our acquisition] equation in certain markets,” Shammo said in reference to Verizon’s bidding strategy. “And so we became much more diligent on what markets we strategically wanted and [which] we were willing to let go because when you looked at it, if I was to get what I wanted initially when I went in, I would have spent an extra $6 billion when I could create the same capacity with $1.5 billion by building it.”

In the most recent auction, Verizon Wireless considered spectrum acquisitions crucial in California, where it added frequencies in Los Angeles, San Diego and San Francisco. But Verizon gave up bidding on spectrum for densely populated New York and Boston where the asking price grew too high. That forces Verizon Wireless to increase the efficiency of its existing network in those cities. It will do so by deploying more cell towers to divide the traffic load, as well as adding microcells and other small-area solutions in high traffic urban areas.

Despite not getting everything it wanted, Verizon took the auction results in stride, claiming its network was fully capable of handling growing traffic loads even in areas where it failed to win new spectrum.

“People think that spectrum is the Holy Grail and if you don’t have enough spectrum, you can’t have the capacity,” Shammo said. “But actually that’s not true now because technology has changed so much. If you look at small cell technology, diversified antenna systems, and when you think [about] Chicago, if you walk down the street, you see small cells on lamp posts. So, the municipalities are starting to open up to that small cell technology.”

AT&T paid $18.2 billion for nearly 250 licenses, compared with $10.4 billion Verizon will spend on 181 licenses. The presence of Dish Networks in the bidding clearly irritated AT&T and Verizon, primarily because the satellite dish provider incorporated two “designated entities” — SNR Wireless LicenseCo and Northstar Wireless — as bidding partners, winning up to 25% off their bids as part of a “small business discount.” The two DEs won over $13 billion in licenses with $3 billion in savings.

AT&T accused Dish of circumventing auction activity rules and distorting the bidding.

“As a result, Dish the corporate entity won no licenses,” said Joan Marsh, AT&T’s vice president of federal regulatory matters. “The Dish DEs, who each enjoyed a 25% discount, won substantial allocations.”

Marsh complained Dish already controls around 81MHz of spectrum that remains unused for wireless telecom services.

Dish also made life difficult for large carriers who have learned to predict the likely bidding strategies of their competitors based on experience. Many were surprised Dish managed to both bid up prices and win a substantial percentage of spectrum, all for a wireless business it has yet to build.

T-Mobile was not happy either. CEO John Legere called the auction “a disaster for American wireless consumers.” T-Mobile suffered considerably in the auction, outspent by Dish & Friends 132 times for important wireless licenses.

“Three companies alone spent an insane $42 billion between them, grabbing a ridiculous 94 percent of the spectrum sold at this auction,” Legere wrote, referring to AT&T, Dish Network and Verizon Wireless. “This whole thing should scare the hell out of you and every other wireless consumer in the U.S., because there is another important auction next year, and the results have to be different if wireless competition is going to survive.”

With the auction over, Verizon Wireless will continue to shift its spectrum usage around to accommodate network changes. Verizon will continue to emphasize enlarging 4G LTE services while gradually reducing the percentage of its network used for other purposes. Verizon expects to shut off its CDMA voice network in the early 2020s and is reducing the amount of spectrum dedicated to supporting its legacy 3G network.

Verizon’s FiOS expansion is still dead.

Verizon Communications signaled today it plans further cuts in investments for its wireline network, which includes traditional copper-based telephone service and DSL as well as its fiber-optic network FiOS.

“We will spend more CapEx in the wireless side and we will continue to curtail CapEx on the wireline side,” Verizon’s chief financial officer Fran Shammo told investors this morning. “Some of that is because we are getting to the end of our committed build around FiOS.”

Instead of expanding its FiOS fiber to the home network to new areas, Verizon is trying to increase its customer base in areas previously wired. It is less costly to reconnect homes previously wired for FiOS compared with installing fiber where copper wiring still exists.

Verizon continues to lose traditional landline customers, so the company is increasingly dependent on FiOS to boost wired revenue. The fiber network now accounts for 77% of Verizon’s residential wireline revenue.

Wherever FiOS exists, it has taken a significant number of customers away from cable competitors. FiOS Internet has now achieved 41.1% market penetration, with 6.6 million customers, up 544,000 from last year. Of those, the majority want broadband speeds they were not getting from the cable company. At the end of 2014, 59% of FiOS Internet customers subscribe to broadband speeds above 50Mbps, up from 46% at the end of 2013.

Despite the success of FiOS, Verizon’s senior management continues to devote more attention to its highly profitable Verizon Wireless division, spending an even larger proportion of its total capital investments on wireless services.

In 2014, Verizon spent $17.2 billion on capital expenditures, an increase of 3.5% over 2013. But only $5.8 billion was spent on maintaining and upgrading Verizon’s landline and FiOS networks, down 7.7% over 2013. Verizon Wireless in contrast was given $10.5 billion to spend in 2014. The company is using that money to add network density to its increasingly congested 4G LTE network. In many cities, Verizon Wireless is activating its idle AWS spectrum to share the traffic load and is accelerating deployment of small cell technology and in-building microcells to deal with dense traffic found in a relatively small geographic area — such as in sports stadiums, office buildings, shopping centers, etc.

Verizon Wireless is branding its network expansion “XLTE,” which sounds to the uninitiated like the next generation LTE network. It isn’t. “XLTE” simply refers to areas where expanded LTE bandwidth has been activated. Unfortunately, many Verizon Wireless devices made before 2014 will not benefit, unable to access the extra frequencies XLTE uses.

With Verizon increasing the dividend it pays shareholders, the company is also cutting costs in both its wired and wireless divisions:

• Verizon Wireless’ 3G data network will see a growing amount of its available spectrum reassigned to 4G data, which is less costly to offer on a per megabyte basis. As Verizon pushes more 4G-capable devices into the market, 3G usage has declined. But the reduced spectrum could lead to speed slowdowns in areas where 3G usage remains constant or does not decline as quickly as Verizon expects;
• Verizon will push more customers to use “self-service” customer care options instead of walking into a Verizon store or calling customer service;
• The company will continue to move towards decommissioning its copper wire network, especially in FiOS areas. Existing landline customers are being encouraged to switch to FiOS fiber, even if they have only landline service. Copper maintenance costs are higher than taking care of fiber optic wiring;
• Verizon has accelerated the closing down of many central switching offices left over from the landline era. As the company sells the buildings and property that used to serve its network, Verizon’s property tax bill decreases;
• Verizon will continue cutting its employee headcount. Shammo told investors in December, Verizon Communications cut an extra 2,300 employees that took care of its wired networks.
