Using Calibration to Optimize Performance in Crucial Measurements
The week starting September 15th will no doubt go down in history for the global turmoil set off by the near meltdown in the financial markets following the demise of investment banks Lehman Brothers (declaring bankruptcy), Merrill Lynch (selling itself to Bank of America) and precipitous plunge in stock price of Goldman Sachs and Morgan Stanley as well as insurance giant AIG. Markets worldwide seemed to be in free fall. By mid-week the US government had stepped in to rescue AIG with an $85B loan and was looking into a broader fix to stabilize the crisis. This news was hard to miss.
Amid the rash of bad news emanating from Wall Street, investors could have yet another setback to stew over. Technology stocks, once a haven from the storms roiling the financial sector, again are vulnerable. For much of the past year, investors have considered technology companies something of a safe harbor from the credit crunch and the soaring price of oil and other commodities. As the crisis worsened, tech companies' values were boosted (BusinessWeek, 9/10/07) by their stores of cash, paucity of debt, and substantial overseas sales that benefited from a weak dollar. Yet a rally by the dollar since mid-July is quickly erasing currency gains at many tech outfits, while layoffs, tight access to credit, and slumping profits exact an even greater toll on companies' IT budgets. As a result, the argument for buying tech stocks is getting thinner, according to analysts.
That said, technology stocks surged in late trading Thursday, lifted by a broad market rally that was triggered by hope regulators would step in to help solve the credit crunch and after a range of actions to curb short selling. The Nasdaq Composite Index, home to many leading tech stocks, rose more than 100 points to 2,199 after falling 85 points, or almost 5%, Wednesday.
Nothing coming across our desks this week reflected the colossal news coming out of Wall Street, which may be just as well. We did receive news on a new report on the role of Picocells and Femtocells in the initial LET architecture roll-out, a report on the world’s mobile infrastructure market and a report on RFID adoption across a broad range of verticals (all three reports from ABI Research) Other news concerned partnerships (AWR and Mentor Graphics, RMI and CSR, SiGe Semi), new products and more.
From ABI Research came three market reports. The first “Picocells and Femtocells Part of Initial LTE Architecture” claims that it is likely that femtocells and picocells will form an integrated part of the initial rollouts of Long Term Evolution (LTE) networks.
These cellular mini-base stations, which offer improved wireless coverage indoors, have been generating considerable interest in mobile wireless markets, and according to senior analyst Nadine Manjaro, LTE deployment is expected to boost shipments and revenues. “In most parts of the world, LTE will be deployed using higher frequency bands. Higher frequencies penetrate structures less effectively than low frequencies, so femtocells and picocells offer an attractive way to compensate for lower indoor signal strength and provide LTE’s touted bandwidth. Our forecasts show an upswing in femtocell and picocell penetration that coincides with the expected LTE deployment timeframe.” In Europe and other regions, LTE will operate in the 2.6 GHz band, although in the US it will largely be found in 700 MHz range, and in China TD-LTE will be most likely be deployed in the 1880 to 1920 MHz and 2010 to 2025 MHz bands, so the need for femtocells may be considered less pressing in those areas.
In contrast to other 3G technologies that preceded the introduction of femtocells, when LTE arrives these products will have been available for some time, and will be included in the original planned LTE architecture. “We will see some macro network deployment of LTE,” says Manjaro, “but not to the same extent that we saw with previous technologies. I think a large portion of it will deployed via femto and picocells alone, with macro deployments following later.” Some observers even suggest that all LTE deployments will initially use femtocells alone. ABI has also stated that while Ericsson leads the world’s mobile infrastructure market, it faces stiff competition from Nokia Siemens Networks and Alcatel-Lucent as well as from some Asian vendors, especially a buoyant Huawei.
“As of 1Q 2008, Huawei owned almost 8 percent of the world’s cellular infrastructure market, compared to Ericsson at nearly 29 percent and Nokia Siemens at more than 23 percent,” said ABI Research senior analyst Nadine Manjaro. “But don’t be deceived by that disparity: Huawei is the vendor to watch, given its overall increase in market share over the last six quarters. And squarely in its sights is the number three vendor, Alcatel-Lucent, with a market share just over 13 percent.”
In the second quarter of 2008, Alcatel-Lucent suffered one of its worst quarters since its merger. During the first half of 2008, the company’s wireless infrastructure shipments decreased 63 percent compared to the second half of 2007. Two of its top customers in North America – Sprint and Verizon Wireless – completed EV-DO Rev A deployments, which led to decreased CDMA spending. Sprint alone reduced CAPEX by $1 B compared to 2Q 2007.
“China is the leading wireless market and its top three operators plan to spend close $80 B on infrastructure over the next three years,” continued Manjaro. “This, along with strong growth in India and Africa, might catapult Huawei into the lead within three to five years. At the very least, Ericsson is not likely to be in any kind of ‘comfort zone’ as it tries to face down the growing threat from the muscular Chinese giant.”
An online end-user survey recently completed by ABI Research has found that RFID is being used or evaluated for a growing number of applications across a wide range of vertical industry sectors. Over 180 organizations worldwide responded to the survey, providing a detailed picture of the current state of RFID adoption and identifying key markets trends, system requirements, expenditures and more.
According to ABI Research director Michael Liard, “The survey results validate ABI Research’s view that RFID opportunities are broad in today’s market. Virtually every economic sector and industry where data needs to be collected or objects need to be tracked holds the potential for RFID applications.”
End-user respondents cite the use and evaluation of RFID technology across multiple application segments, ranging from security-based applications to supply chain management to multiple flavors of asset tracking and more. Organizations of all kinds are increasingly using and evaluating RFID systems to improve the tracking of objects, assets, goods, and materials within the “four walls”, in yards and campuses, open loop environments and beyond.
Liard continues, “The research also reveals that end-users are looking for a total solution. This requirement is leading large percentages of users to secure their systems direct from RFID manufacturers as well as from systems integrators that can provide all solution components via a partner network.” The results reveal that respondents feel these vendors and integrators have a deeper understanding of RFID technology, as well as vertical and/or application market specialization.
