Brand new Wilson 867501 Cellular RF Signal Detector!

Friday, June 29th, 2012

The RF Signal Detector helps you find the strongest available signal for your cellular devices!

The RF Signal Detector from Wilson Electronics is a quad-band detector that finds the available cellular signals in any location and displays signal attributes on the detector’s LCD screen. This signal detector can be paired with a variety of Wilson antennae to map the local cellular frequency environment and find the direction of the cell tower that provides the strongest signal. This allows you to precisely point a directional antenna, so that a Wilson signal booster can maximize indoor cellular coverage.

The Signal Detector’s LCD screen displays the frequency of a detected signal, the range of pass bandwidth in megahertz (MHz) and the signal strength in decibels (dB). Easy-to-use button controls located just under the screen allow t he user to move between frequency bands and channels. This devices works with the 800 MHz (Cellular), 1900 MHz (PCS), 2100 MHz (AWS), and 700 MHz LTE (bands 12 and 13) frequency bands. The RF Signal Detector is the perfect tool to help you optimize a Wilson signal booster installation, or tune a directional antenna.

Sprint Nextel LTE launch set for July 15

Thursday, June 28th, 2012

Sprint Nextel’s LTE network is set to officially launch July 15, with initial coverage to include portions of Atlanta, Houston, Dallas, Kansas City, and San Antonio. The carrier has been hyping its LTE moves since last October, with the network deployment included as part of its ambitious Network Vision initiative. The initial launch markets were included in Sprint Nextel’s previous announcement for its initial 10 markets.

The LTE launch will place the carrier on equal footing, at least in basic marketing, with larger rivals Verizon Wireless and AT&T Mobility, which have been aggressively expanding their respective LTE coverage. The move also puts Sprint Nextel into the LTE game ahead of an expected fall launch of Apple’s latest iPhone device that most predict will include LTE capability.

The launch also keeps Sprint Nextel on track for its planned mid-2012 launch, followed by 250 million potential customers covered by the end of 2013. The carrier announced earlier this week that it was set to re-hire 240 employees that had previously been moved to Ericsson as part of a network reorganization plan. A Sprint Nextel spokeswoman said the transfer should be complete by the end of July. Ericsson, which is handling the Network Vision work with Alcatel-Lucent and Samsung, is on the hook for the network upgrade for most of the initial LTE launch markets.

Sprint Nextel’s LTE network will initially rely on 10 megahertz of spectrum in the 1.9 GHz G-Block spectrum band. The carrier said it plans on eventually re-farming other spectrum bands in support of the service, including plans to use its 800 MHz spectrum. The band is currently supporting its iDEN network, which is set to be shuttered by mid-2013, as well as recently launched CDMA2000 1x-Advanced services.

The carrier has already been seen seeding the market with LTE-enabled devices, including smartphones and wireless modems.

Sprint Nextel’s LTE network is crucial to its ability to compete at least on a marketing level with larger rivals Verizon Wireless and AT&T Mobility. As was seen with its initial move into the “4G” marketing space with its WiMAX offering, a significant segment of wireless consumers are drawn to the latest and greatest technologies, even if they have no idea what they are or how they benefit them.

Sprint Nextel’s next battle will be to prove that its LTE service is on par with its larger rivals despite the use of approximately half the spectrum assets. Improving coverage will also be key in terms of marketing and customer satisfaction, which could prove a challenge in the short term due to the carrier’s use of 1.9 GHz spectrum for the initial LTE rollout.

T-Mobile and Verizon swap AWS in 218 markets

Tuesday, June 26th, 2012

T-Mobile USA, one of the most vocal critics of Verizon’s $3.9 billion AWS purchase, appears to have reached a truce with its larger competitor.

The two operators said today they will swap AWS spectrum in 218 markets, a deal giving T-Mobile a “net gain” of spectrum to use for its forthcoming LTE network.

“This is good for T-Mobile and good for consumers because it will enable T-Mobile to compete even more vigorously with other wireless carriers,” T-Mobile CEO and President Philipp Humm said in a statement, calling the spectrum “critical.”

T-Mobile has repeatedly asked the FCC to stop Verizon from purchasing a nationwide swath of AWS spectrum from four cable operators, arguing the deal will prove anticompetitive by concentrating too much spectrum in the hands of a single company. T-Mobile has also attacked Verizon for not using AWS spectrum it purchased in 2006, and says Verizon isn’t using its spectrum as efficiently as it claims.

The agreement between the two companies will likely remove T-Mobile as an opponent to Verizon’s spectrum deal with the cable providers, since it is contingent upon FCC approval of the larger AWS transaction.

The agreement includes licenses Verizon is working to purchase from the cable operators and spectrum from a separate deal with Leap Wireless International. The contract also depends on the closure of the Leap deal.

Verizon is working to close the transaction with its cable partners by late summer.

Some critics of Verizon’s AWS purchase from cable operators have asked the FCC to force Verizon to divest some of the licenses. T-Mobile may have been able to benefit from the forced divestitures, but its arrangement with Verizon gives it an amount of certainty it would have otherwise lacked.

If its new deal with Verizon goes through, T-Mobile will gain spectrum covering 60 million people in Philadelphia; Washington, D.C.; Detroit; Minneapolis; Seattle; Cleveland; Columbus, Ohio; Milwaukee; Charlotte, N.C.; Raleigh-Durham, N.C.; Greensboro, N.C.; Memphis, Tenn.; and Rochester, N.Y.

In turn, Verizon will gain spectrum covering 22 million people and an unspecified “cash consideration.”

The contract between the two operators also includes spectrum swaps in a number of markets “to create more contiguous blocks of spectrum and re-align spectrum in adjacent markets.”

Verizon previously offered to sell off its 700 MHz A block and B block licenses if the AWS deal closes, an offer T-Mobile rejected on the grounds that the A block licenses faced too many problems with interference to be viable.

WCDMA voice gets another look as HSPA+ takes off

Thursday, June 21st, 2012

Circuit-switched voice is starting to seem so passé, but it’s going to be around for quite awhile. That’s why companies such as InToTally and Qualcomm are developing methods to make WCDMA voice more efficient so operators can wring out additional spectrum capacity to make room HSPA and HSPA+ data services.

Though they are taking different approaches, both companies are looking to limit the amount of power used by voice communications over WCDMA so there is more spectrum available for HSPA and HSPA+. “There is a huge amount of data coming and the voice is occupying most of the spectrum,” said InToTally’s CEO Alvaro Lopez-Medrano.

The mobile communications industry is migrating toward VoLTE and VoHSPA, “but it will take some time before those services have the quality and ubiquity of circuit-switched voice,” said Rasmus Hellberg, Qualcomm’s senior director of technical marketing.

“4G is frequently promoted as the way to meet the huge demand for mobile capacity. But by 2016 only about 26 percent of subscribers will have moved to 4G networks and a hybrid solution with 3G will be essential to ensure adequate coverage for voice and data,” said Sue Rudd, director of service provider analysis at Strategy Analytics.

While InToTally and Qualcomm agree on the need to improve WCDMA voice efficiency, they are tackling the issue from different angles. Further, while InToTally’s proprietary approach is already available for licensing, Qualcomm is working to get its approach included in the planned Release 12 of specifications for 3GPP technologies.

Going after the outer loop

InToTally’s solution is based upon solving outer loop power control issues found in CDMA and WCDMA. According to Lopez-Medrano, the OLPC sets the appropriate signal to interference ratio (SIR) target to maintain a given quality criterion, but traditional OLPS approaches based upon the Block Error Rate (BLER) are too slow to accommodate real-time power adaptation to different radio conditions, thus leading to voice communications inefficiencies.

For example, in a standard WCDMA voice call, the initial end-user device’s power is set high at the beginning because the handset and base station are not yet aware of the radio conditions impacting the device. That high setting can causes unnecessary interference with other users, said Lopez-Medrano, and it takes a long time for the power loop to measure the call quality and instruct the device to power down. “We have developed a new technique that looks at a different metric that gathers and processes information much more quickly,” Lopez-Medrano said.

InToTally’s ToT-OLPC technology is aimed a providing faster convergence speed for the radio link between network antennas and mobile handsets, thus improving overall voice efficiency and capacity,” said Lopez-Medrano. Field tests have shown a 20 percent capacity gain on average and 40 percent gain in highly saturated areas, said Lopez-Medrano, adding, “The room for improvement in the outer loop is huge.”
