Small-Cell Power Amplifier Family

Power amplifiers optimized for WCDMA, HSPA, and LTE small-cell applications are available from ANADIGICS, including picocells, enterprise-class femtocells, and high-performance customer premises equipment (CPE).  The AWB7122 and AWB7124 operate in the 1805 MHz to 1880 MHz and 728 MHz to 768 MHz band, respectively, delivering integration and good performance to help manufacturers develop compact wireless infrastructure solutions that consume less power and provide higher throughput with greater coverage.

By offering a broad portfolio of high-performance ¼-Watt and ½-Watt linear power amplifiers optimized for 3G and 4G frequency bands, ANADIGICS enables wireless network equipment manufacturers to meet this infrastructure challenge.

The AWB7122 and AWB7124 power amplifiers provide 16 percent and 14.5 percent efficiency, respectively, to minimize power consumption and offer greater flexibility in the choice of network power sources.  Both the AWB7122 and AWB7124 deliver linearity of -47 dBc ACPR at +24.5 dBm output power and 30 dB of RF gain to provide higher data rates with a greater coverage area.  The power amplifiers are available in a 7 millimeter x 7 millimeter x 1.3 millimeter surface mount package with integrated RF matching to reduce PCB space requirements.  www.anadigics.com

DISH, Ntelos Test LTE-to-the-Home

It’s easy to find people that don’t trust DISH Network’s Charlie Ergen, but it’s hard not to get titillated by some of the technology plays that he brings to Sprint and Clearwire. To Sprint, he brings a multimedia package – mobile and fixed video, voice, and data. Additionally, his company brings a fixed-broadband wireless play using spectrum in the 2.5 GHz band, which would complement the spectrum holdings of both Sprint and Clearwire.

The week, DISH and nTelos Wireless, a rural wireless provider, announced the commencement of a fixed broadband wireless test in rural Virginia using LTE technology, with speeds ranging from 20 Mbps to more than 50 Mbps.

As part of the demonstration, two wireless tower test sites were activated in the Blue Ridge Mountains near Waynesboro and Afton, Va. BandRich ruggedized outdoor routers with built-in high-gain antennas were installed on the roofs of the homes to receive the signal. Ericsson and Alcatel-Lucent provided equipment and assisted in the installation.

The final story has yet to be written of the DISH/Sprint/Clearwire/Softbank merger-palooza. But with a significant portion of households in rural America underserved by wireline broadband, a fixed wireless LTE solution just might find a home in the country, no matter who provides it.

OpEx to Overtake CapEx by 2015 — U.S. LTE Forecast

As network build outs begin to taper off and subscribers take up LTE devices, carrier operating expenditures will surpass capital expenditures by 2015 according to a report released by iGR Market Research last week.

“Most of the largest U.S. operators are already well advanced in their LTE network rollouts,” Iain Gilliott, president and founder of iGR, wrote in a press release. “Others may lag behind, but LTE deployments overall are still progressing quickly – perhaps more quickly than could have been foreseen 12 to 18 months ago.”

The major operators have been investing capital expenditures in LTE over the last two to three years and now as their LTE subscriber base is growing, they are incurring increased LTE operating expenses, according to the report.

Based on the anticipated rapid growth of LTE subscribers and data traffic on the networks, total U.S. LTE infrastructure OpEx projected to be $57.4 billion, while CapEx is expected to be only $37.7 billion between 2012 and 2017.

“Operators are striving to provide sufficient coverage to be competitive and sufficient capacity to meet the needs of the growing subscriber base, while minimizing unnecessary CapEx and OpEx,” said Gillott. “This report clearly shows there remains a limited amount of time for significant CapEx expenditures in the U.S. LTE infrastructure market, and that the operators’ LTE OpEx levels will overtake LTE CapEx levels in two years.”

1Q Signals Start of Phase 2 of LTE – Moreland

The next wave of tower leasing, network densification, has taken root, Ben Moreland, CEO, president and director of Crown Castle International, told the company’s first quarter earnings call.

With all four major U.S. wireless carriers engaged in major network upgrades, Crown experienced a significant amount of activity in the first quarter, logging more than 75 percent of the 2013 leasing activity into its application pipeline.

Application volume by revenue in the first quarter grew at twice the pace of last year, and 60 percent of that number was from new tenants collocating on towers they were not previously on.

“This is a trend we have been anticipating for some time, as some of the carriers are nearing completion of their LTE nationwide build out,” Moreland said. “We have been expecting to see in-fill sites, or densification, as a second wave of LTE network deployment, providing us with a longer runway of expected future growth as the carriers strive to maintain network quality and reliability through cell splitting in the face of exponential growth in mobile technology demand.”

Given the location of 74 percent of Crown’s sites in the top 100 markets, the company expects to benefit from the majority of network densification through new leases. Overall, LTE deployment should be the gift that keeps on giving to the tower industry into the future, Ted Abrams, Abrams Wireless, told AGL Bulletin.

“Working with clients deploying LTE, and those responding to major carrier requests, I see strong indications that LTE deployments are only just beginning. Evidence indicates demand growth for wireless network infrastructure — assets that support and connect small cells and macros – continuing for many years to come,” Abrams said.
