NTT Sees Gains in Optical Access as Fixed Voice Continues to Drag

The steady decline in revenue from fixed voice services outpaced revenue gains in optical access services, leading NTT to report a 1.8% drop in net profit during a quarter marked by recovery from Japan's historic earthquake on March 11. Quarterly revenue came in at 2.537 trillion yen for the period ending June 30, up 1.5% compared with a year earlier as the company's international business expanded.

NTT DOCOMO Now Has Over 205,000 LTE Subscribers

As of the end of July, NTT DOCOMO was serving 205,700 Xi LTE subscribers, up by 84,300 for the quarter. The company was also serving 57,508,200 FOMA 3G subscribers, up by 184,200. http://www.nttdocomo.co.jp

TELUS Q2 Revenue Rises 6.4% YoY

Driven by a nearly 10 per cent growth in wireless revenue and three per cent growth in wireline revenue, TELUS reported Q2 revenue of $2.55 billion, an increase of 6.4 per cent over the same period last year. EBITDA of $950 million increased by almost three per cent due to revenue growth, offset in part by higher costs to acquire and retain wireless customers and to support Optik TV growth. Net income and earnings per share (EPS) for the second quarter were $324 million and $0.99, representing year-over-year increases of 7.3 and 5.3 per cent, respectively.


Some highlights:


The company added 94,000 new wireless subscribers in the quarter.


Wireless data revenue surged by 49 per cent, which more than offset declining voice revenues, resulting in wireless average revenue per unit (ARPU) growth of 2.5 per cent.


In the wireline segment, the company added 46,000 TV customers to surpass the 400,000 subscriber milestone. Combined with 13,000 new high-speed Internet subscribers this performance helped generate wireline data revenue growth of 14 per cent.


TELUS boosted its guidance for consolidated revenues by $200 to $300 million based on increases in both the wireless and wireline business segments. Capital expenditures are also increased from approximately $1.7 billion to approximately $1.8 billion, primarily reflecting an increase in this year's investment in the LTE rollout.

Jobs4America: 4,000 New Call Center Jobs Per Month Enabled by Broadband

Widespread broadband deployment makes it economically feasible to bring back many call center jobs from foreign countries, according to Jobs4America – a coalition of call center operators that aims to create 100,000 new broadband-enabled, call center jobs in the United States over the next two years. The group estimates that an average of 4,000 call center jobs are already being created each month in the U.S. By their count, over 18,000 new call center jobs were created in the U.S. during Q2.


Already more than 5 million Americans work in contact centers. Currently 17 percent of all call center positions (in-house and outsourced) are home based and 80 percent of U.S. companies plan to use at home agents in the next
few years, according to figures cited from Frost & Sullivan.


On Thursday, FCC Chairman Julius Genachowski presided at an event in Jeffersonville, Indiana where 175 new call center jobs were being created. He also announced 100 new call center jobs in Newark, New Jersey, 300 new jobs in Holland, Michigan, and 4,000 new jobs in St Lucie, Florida where unemployment is 12.5 percent.


Chairman Genachowski said, "This initiative involves meaningful job creation that will have a meaningful
impact across America. Bringing broadband to your town and home in the 21st century is like bringing in
electricity in the 20th – connecting you and your community to the larger economy and opening up new worlds
of commerce and opportunity."http://www.jobs4america.net/http://www.fcc.gov

Deutsche Telekom Reports Decline in Revenue & Profitability

Citing a persistently tough economic environment, especially for its T-Mobile USA operation, Deutsche Telekom reported Q2 revenue of EUR 14.5 billion, a decline of 6.8 percent year-on-year. Revenue for continuing operations, excluding T-Mobile USA, fell by 3.3 percent. On a like-for-like basis (i.e., excluding T-Mobile UK), the drop in revenue back in the first quarter amounted to 3.7 percent. Adjusted EBITDA for the Group as a whole fell by 6.5 percent to EUR 4.7 billion. The decrease in continuing operations was 2.6 percent.

Adjusted net profit was positive, increasing by 16.8 percent in the second quarter of 2011 compared with the same period last year to EUR 951 million. Negative special factors came to almost EUR 0.3 billion more than in the same period last year, particularly as a consequence of the costs of staff reorganization, resulting in an unadjusted decrease of 26.7 percent to EUR 348 million. The Group recorded an 18.7-percent increase in free cash flow to EUR 1.8 billion.

"Although these figures are not a cause for celebration, they still give us reason to be confident that we will achieve our targets in a persistently difficult environment," said René Obermann, CEO of Deutsche Telekom. "We are now also seeing light at the end of the tunnel in Southeastern Europe."

Some highlights:

Germany



During Q2, the number of broadband lines overtook the number of conventional telephone lines for the first time.

There were 295,000 line losses, an all-time low during the quarter.

Deutsche Telekom's broadband market share held steady at around 46 percent.

The number of users connected to the Internet-based TV service Entertain increased by 34 percent to 1.3 million within a year.

Mobile Internet revenue increased by over 30 percent year-on-year to EUR 409 million, due in large part to the growth in the use of smartphones.

Smartphones now account for more than 60 percent of all devices sold, a year-on-year increase of 30 percent.

Revenue in the Germany segment fell by 3.4 percent to EUR 6 billion compared to the second quarter of 2010.

Service revenues in mobile communications declined by 3.4 percent to EUR 1.7 billion, most due to the impact of the regulatory decision to drastically cut termination charges.

Europe

Total revenue fell by 5.5 percent to EUR 3.8 billion compared with the same quarter in 2010. The decrease in the first quarter, adjusted to take into account the deconsolidation of T-Mobile UK, had still amounted to 8 percent. The situation is similar for adjusted EBITDA, which fell by 8 percent year-on-year in the second quarter, while the decrease in the first quarter of this year had still stood at 13 percent.

The best performers were Croatia, with an adjusted EBITDA margin of 45.4 percent, and the Magyar Telekom Group, with a margin of 43.9 percent, adjusted for the influence of the special tax in Hungary. A margin of 38.9 percent was achieved for mobile business in Poland, where the T-Mobile brand was launched in the second quarter in a nationwide campaign.

The economic situation in Greece and Romania remains difficult and continues to put noticeable strain on the business of the OTE Group, where revenue and earnings have fallen significantly.

Systems Solutions

Revenue increased by 1.5 percent to EUR 2.3 billion. External revenue growth stood at 1.7 percent while there was a disproportionately significant increase of 3.1 percent in international revenues. The corporate customer segment recorded a 14.7 percent decrease in adjusted EBITDA to EUR 0.2 billion, due primarily to the aforementioned start-up costs.

T-Mobile USA Sees Net Customer Loss, Higher Data ARPU

T-Mobile USA reported a net loss of 50,000 mobile subscribers in Q2 along with slightly higher ARPU for data services, leading to service revenues of $4.6 billion, consistent with service revenues in the first quarter of 2011.


"The United States remains a difficult market for Deutsche Telekom, but we see improvements compared to the first quarter of 2011. T-Mobile USA will continue its strategy with the extended HSPA+ 42 coverage and continued data growth," said René Obermann, CEO of Deutsche Telekom.


Some highlights:


T-Mobile USA served 33.6 million customers at the end of the second quarter of 2011, generally consistent with the first quarter of 2011 and the second quarter of 2010.


Net customer losses of 50,000 compared to net losses of 99,000 in the first quarter of 2011 and 93,000 in the second quarter of 2010.


The improvement in net contract customer losses was driven primarily by the introduction of new unlimited rate plans in the second quarter and faster growth in our connected device business.


Connected device customers totaled 2.3 million at June 30, 2011.


Prepaid net customer additions, including MVNO customers, were 231,000 in the second quarter of 2011, down 18% compared to 283,000 in the first quarter of 2011 and up substantially from the 199,000 net losses in the second quarter of 2010.


Blended churn, below), reflecting both contract and prepaid customers, decreased to 3.3% in the second quarter of 2011 from 3.4% in both the first quarter of 2011 and the second quarter of 2010.


The year-on-year increase in contract churn was primarily driven by competitive pressures in the US wireless industry which have continued to negatively impact T-Mobile USA's contract customer base.


Prepaid churn decreased in the second quarter of 2011 to 6.6%, from 6.7% in the first quarter of 2011 and 7.6% in the second quarter of 2010.


The sequential decrease in prepaid churn was driven by a shift in the customer base towards traditional prepaid products, which was partially offset by higher MVNO churn.


Year-on-year, prepaid churn decreased due to lower traditional prepaid product churn resulting from the success of T-Mobile USA's recently introduced prepaid monthly unlimited plans.


Blended ARPU was $46 in the second quarter of 2011, consistent with the first quarter of 2011, but lower than $47 in the second quarter of 2010 driven by a shift in the customer base towards prepaid plans.


Contract ARPU was $53 in the second quarter of 2011, up from $52 in the first quarter of 2011 and each of the previous four quarters.


Prepaid ARPU was $18 in the second quarter of 2011, consistent with both the first quarter of 2011 and second quarter of 2010.


Data service revenues were $1.4 billion in the second quarter of 2011, up 17% from the second quarter of 2010.


Data service revenues in the second quarter of 2011 represented 30% of blended ARPU, or $13.60 per customer, up from 29% of blended ARPU, or $13.10 per customer in the first quarter of 2011, and 25% of blended ARPU, or $11.60 per customer in the second quarter of 2010.


9.8 million customers were using smartphones enabled for the T-Mobile USA 3G/4G network. This represents a net increase of 50% or nearly 3.3 million customers using smartphones from the second quarter of 2010.


3G/4G smartphone customers now account for 29% of total customers, up from 27% in the first quarter of 2011 and 19% in the second quarter of 2010.

Sierra Wireless Sees Q2 Drop from Clearwire, Barnes & Noble

Sierra Wireless reported Q2 revenue of $139.9 million, a decrease of 12% compared to $159.1 million in the second quarter of 2010, and a decrease of 3% compared to $144.3 million in the first quarter of 2011. On a GAAP basis, gross margin was $39.1 million, or 28.0% of revenue, in the second quarter of 2011 compared to $46.2 million, or 29.0% of revenue, in the second quarter of 2010.


The company said its year-over-year revenue decrease was principally driven by the loss of revenue from Barnes & Noble and Clearwire, which together accounted for nearly $25 million in revenue in the second quarter of 2010.


Mobile Computing revenue in Q2 was $66.0 million, down 13% compared to $75.5 million in the second quarter of 2010.


Machine-to-Machine ("M2M") revenue was $73.9 million, down 12% compared to $83.6 million in the second quarter of 2010. Excluding sales to Barnes & Noble, the company's core M2M business increased 14% in the second quarter of 2011 on a year-over-year basis.


"Notwithstanding a slower than expected start to 2011, Sierra Wireless remains well positioned in our two target markets. In Mobile Computing, we are launching several new 4G LTE products with key operators and PC OEMs. In M2M, we continue to build on our global leadership position and successfully drive value chain expansion," said Jason Cohenour, President and Chief Executive Officer. "Our growth drivers remain intact and despite some product launch delays, we expect significant sequential revenue and earnings growth in the second half of 2011."

Looking ahead, the company expects growth to be driven by the launch of new 4G AirCard products, as well as continued steady year-over-year growth in its core M2M product lines.

Australia's NBN Goes Live in Melbourne

Australian Prime Minister Julia Gillard MP officially switched on the National Broadband Network at a ceremony in a suburb of Melbourne, marking the third NBN site on the mainland.


The fibre network in Brunswick covers approximately 2,689 premises and the first 14 homes are now connected. The trial phase is due to run until late September, after which residents in the Brunswick fibre coverage area are expected to be able to order broadband services over the NBN from retail service providers.

NBNCo noted that work in Brunswick began in October 2010 with construction partner Telstra accessing its existing underground infrastructure in order to help minimise the impact of the rollout on the local community.

"The launch today of the NBN in Brunswick and new construction activity we've announced are the latest steps towards delivery of a crucial piece of nation-building infrastructure. The National Broadband Network has the potential to deliver genuine competition in telecommunications and benefit Australian homes, businesses, schools and hospitals for decades to come," stated NBN Co Chairman Harrison Young.


In addition, NBNCo released details on the first communities in five states and territories that will become the first in the country to receive NBN Co's high-speed fixed wireless service, which promises 4G speeds of up to 12 Mbps. The fixed wireless component of the NBN rollout is expected to be completed by 2015 and aims to pass approximately half a million homes and business, four percent of the nation's total addressable premises. The rollout will require the use of around 2300 masts, including existing ones where possible. The fixed wireless service differs from mobile wireless networks in that it is designed to serve a precisely designated number of homes and businesses, each with a wireless receiver affixed to their premise.


The first to receive NBN wireless service will be homes, businesses and institutions in the less densely populated rural and regional communities that surround Geraldton (WA), Toowoomba (Qld), Tamworth (NSW), Ballarat (Vic) and Darwin (NT).


The network is designed to deliver wholesale access speeds of up to 12Mbps*. NBN Co anticipates higher speeds becoming available as technology advances and the network is upgraded. http://www.nbnco.com.au/

  • In May 2011, NBN Co awarded a 10-year contract to Ericsson to design, build and operate a 4G fixed-wireless network. The deal is valued at up to AUS $1.1 billion.

Clearwire Loses Customers in Q2, Seeks Funds for LTE

Clearwire reported Q2 revenue of $322.6 million. Retail revenue and other revenue was $191.1 million and retail average revenue per user (ARPU) was a record $47.59. Pro forma wholesale revenue was $102.6 million in the second quarter 2011, or $6.18 in pro forma wholesale ARPU. Consolidated pro forma revenue and pro forma wholesale revenue exclude approximately $16.1 million of revenue related to wholesale services provided by Clearwire to Sprint in the first quarter 2011, and approximately $12.8 million of a $28.2 million settlement amount from Sprint which relates to wholesale services provided prior to 2011. The second quarter 2011 reported net loss from continuing operations attributable to Clearwire was $160.5 million, or $0.65 per basic share, and the second quarter 2011 pro forma net loss from continuing operations attributable to Clearwire was $167.0 million, or $0.68 per basic share.


Clearwire ended Q2 2011 with approximately 7.65 million total subscribers, up 365% from 1.64 million subscribers in the second quarter 2010. The subscriber base consists of 1.29 million retail subscribers and 6.36 million wholesale subscribers. During the second quarter 2011, Clearwire added 1.54 million total net new subscribers, comprised of 39,000 retail and 1.50 million wholesale net new subscribers. Clearwire's wholesale subscribers consist primarily of users of 3G/4G smartphone devices.


"Looking ahead, we will continue to seek funding to fuel our growth with the belief that our 4G network, growing customer base, unmatched and unencumbered spectrum, and notable wholesale partners put us in a uniquely advantageous position — one that we intend to maximize," said John Stanton, Chairman and Interim Chief Executive Officer of Clearwire.

Second quarter 2011 aggregate network usage by wholesale customers increased 42% as compared to first quarter 2011, driven primarily by growth in aggregate smartphone usage, which increased 74% over the same period.


Clearwire now expects to end 2011 with approximately 10 million subscribers, with most of the new subscribers coming from its wholesale business. This is an increase from the previous guidance of 9.5 million subscribers provided in May 2011. Before any impact of an LTE deployment, the company expects capital expenditures in 2011 to be less than $400 million, and operations to generate positive adjusted EBITDA in early 2012 as a result of continued implementation of aggressive cost efficiencies aimed at improving cash flow.


Clearwire also said it is looking for $600 million in new funding for the LTE rollout. It is also seeking $150-350 million as working capital to support its existing operations.

Comcast Reports Jump in Business Service, Internet Service

Driven by a 10.3% increase in high-speed internet revenue and a 41.7% increase in business services revenue, Comcast's cable revenue increased 5.6% to $9.3 billion compared to $8.8 billion in the second quarter of 2010. Advertising revenue increased 3.7%, reflecting a slowdown in automotive advertising and lower political advertising in the second quarter of 2011. Monthly average total revenue per video customer increased 8.9% to $137.51, reflecting a growing number of residential customers taking multiple products, rate adjustments and a higher contribution from business services.


For the six months ended June 30, 2011, Cable revenue increased 5.7% to $18.4 billion compared to $17.4 billion in 2010.


For the six months ended June 30, 2011, Cable operating cash flow increased 7.2% to $7.6 billion compared to $7.1 billion in 2010. Year-to-date operating cash flow margin was 41.4% compared to 40.9% in 2010.


For Q@, cable capital expenditures increased 5.5% to $1.2 billion, reflecting increased investment in network infrastructure to enable product enhancements, including faster speeds in high-speed internet, as well as increased investment to support expansion in business services. Cable capital expenditures equaled 12.6% of Cable revenue in the second quarter of 2011. For the six months ended June 30, 2011, Cable capital expenditures increased 10.0% to $2.2 billion, representing 12.1% of Cable revenue.

Also in Q2, combined video, high-speed internet and voice customers increased by 99,000, an 18.2% increase compared to second quarter 2010 net additions. For the six months ended June 30, 2011, combined video, high-speed internet and voice customers increased by 737,000, a 9.5% increase compared to net additions in the first six months of 2010.

Clearwire Confirms Plans for TDD-LTE, Sees Capacity Advantage over Peers

Clearwire confirmed its intention to deploy "LTE Advanced-ready" technology in its 4G network while restating its commitment to its existing 4G WiMAX network, which covers approximately 132 million people while serving 7.65 million retail and wholesale customers. The company expects to end 2011 with approximately 10 million 4G customers.


Clearwire said the initial LTE deployment will target densely populated, urban areas of its existing 4G markets where current 4G usage demands are high.


Clearwire said its LTE network will be "LTE Advanced-ready," meaning that it will use spectrum configurations capable of 100+ Mbps downlink speeds. The LTE implementation plan, which is subject to additional funding, contemplates deploying Time Division Duplex (TDD) LTE technology. The plan calls for upgrading the all-IP network architecture and base station radios, as well as some core network elements. The LTE overlay will include the use of multicarrier, or multichannel, wideband radios that will be carrier aggregation capable. Carrier aggregation is a key feature of LTE Advanced that will enable Clearwire to further leverage its spectrum depth to create larger "fat pipes" for deploying mobile broadband service.


In a conference call, Clearwire said it will not use Sprint's "Network Vision" infrastructure for the LTE overlay because it substantially more expensive that overlaying its own network, but the companies are discussing the possibility of using Sprint's "Network Vision" in new markets. The WiMAX infrastructure will be preserved for a significant period. The believes its key competitive advantage is having "the deepest spectrum" on the only globally coordinated 4G band (2.5 GHz). Clearwire holds an average of 160 MHz of spectrum nationwide, more than AT&T and T-Mobile together, in one contiguous band, enabling wider channels for high-bandwidth applications. The company noted that even if LightSquared gets permission to go ahead with a 2x10 MHz LTE wholesale network, the Clearwire network eventually could offer 20x more capacity at each cell site using superior spectrum.


With the overlay initially focused on the most heavily-used urban areas, Clearwire estimate the CAPEX costs for an LTE overlay are $600 million. A typical market overlay can be completed in 12 months of initiating the build.


"This is the future of mobile broadband," said Dr. John Saw, Clearwire's Chief Technology Officer. "Our extensive trial has clearly shown that our 'LTE Advanced-ready' network design, which leverages our deep spectrum with wide channels, can achieve far greater speeds and capacity than any other network that exists today. Clearwire is the only carrier with the unencumbered spectrum portfolio required to achieve this level of speed and capacity in the United States."


Clearwire also noted that since launching its first 4G market in 2009, video has become the largest component of the company's overall data traffic and video traffic itself has increased more than tenfold since 2009.
http://www.clearwire.com
  • In August 2010, Clearwire began testing coexistence scenarios for WiMAX and LTE in Phoenix using both Frequency Division Duplex (FDD) of 40 MHz of spectrum paired in 2 x 20 MHz contiguous channels ("LTE 2X"), and Time Division Duplex (TDD) configurations using 20 MHz of spectrum. Initial tests have recently confirmed that the company's LTE 2X trial network achieved peak download speeds on commercially available equipment and devices in excess of 90 Mbps and upload speeds of more than 30 Mbps. Clearwire expects to conclude the tests in Q1 2011. The company later updated the test reports noting consistent 120 Mbps downlinks using TDD-LTE
  • Last month, Sprint and LightSquared announced a 15-year agreement that includes spectrum hosting and network services, 4G wholesale, and 3G roaming. The deal gives Sprint $9 billion in cash to build out its 4G network and provides LightSquared with a Tier-One partner for bringing its wholesale-only, nationwide LTE + L-Band broadband satellite service to market, should the FCC approve its GPS terrestrial interference mitigation proposals.

    Specifically, LightSquared will pay Sprint to deploy and operate a nationwide LTE network that hosts L-Band spectrum licensed to or available to LightSquared. As a wholesale-only carrier with separate core network operations, LightSquared can sell its 4G broadband capacity produced through this spectrum hosting relationship to Sprint, other wireless carriers, and retail partners.
  • In December 2010, Sprint unveiled its "Network Vision" for consolidating its infrastructure and spectrum into a single, more cost-effective and flexible network. The key idea behind Sprint's "Network Vision" is to operate a single network. Sprint currently uses separate equipment to deploy services on 800 MHz spectrum, 1.9 GHz spectrum and, through its relationship with Clearwire, 2.5 GHz spectrum. The New Vision blueprint calls for the deployment of multimode base stations for delivering 3G/4G services across all of these bands. New remote radio heads at the cell sites would be connected with fiber rather than coaxial risers. The consolidated cell site would be significantly more energy-efficient.
