WiMAX: A Fading Star?
As an article in The Wall
Street Journal points out, the VHS-versus-Betamax war may be a good analogy (in some respects) for WiMAX
versus LTE, which the latter is winning hands down. The article points out a good analysis of the subject on
the TechRadar website, stating that
that Intel (the original champion of WiMAX) has changed its tune. There are currently 20 million WiMaX
subscribers throughout the world and in some places it may survive – but probably not in a meaningful way in
LightSquared Decision This Month?
LightSquared says it believes the FCC will allow
it to become the first wholesale provider of LTE services in the U.S. when it makes it decision sometime this
month, according toLightSquared's
executive vice president, Martin Harriman at the Mobile Future Forward conference in Seattle, according to
FierceWireless. Sprint has already lined up journalists and analysts to hear its 4G roadmap on October 7, and
in July LightSquared gave Sprint the
option to purchase its wholesale LTE network. A week later Sprint's WiMAX provider, Clearwire, declared plans
to build an LTE-advanced network if it can get the money. This would leapfrog LTE and couldn’t be deployed
until after LTE-Advanced becomes a standard. If the FCC gives LightSquared the green light, Sprint could be
launching LightSquared's LTE network as early as next year. Regardless, LightSquared still faces the core
issue of interference to GPS, which seems almost insurmountable.
Dead Satellite to Fall Soon
A functionally dead satellite will fall back to Earth during the last week of September, according to NASA.
The spacecraft, an old NASA climate probe called the Upper Atmosphere Research Satellite (UARS), was
decommissioned in 2005 and has since been slowly losing altitude. The 6 1/2-ton satellite will make a final
uncontrolled plunge through Earth's atmosphere. The Department of Defense is one of the organizations
monitoring it.Pieces of it could land from south of Juneau, Alaska to just north of the tip of South America.
NASA estimates a 1-in-3,200 chance a satellite part could hit someone. Most of it will burn up after entering
Earth's atmosphere. You can track the spacecraft’s demise
A Message from
The Key Role of Multiband Combiners and Band Separators
I've written a lot in this column about interference and for good reason: it's a bigger issue now then
ever for commercial and public safety wireless systems -- and is getting worse. However, wireless carriers
also face the continuing challenge of reducing costs wherever possible, from the device level straight through
to the antenna. Multiband combiners and separators and bandpass combiners are invaluable components that not
only reduce costs but reduce system complexity as well. These versatile products allow the transmit and
receive signals from several wireless bands to be multiplexed into a single antenna, eliminating a variety of
components and helping to reduce the growing rat's nest of cables within single-carrier or co-located sites.
These bands can be either within a single wireless frequency allocation, such as 700 MHz, or different bands,
for example GSM and PCS, including both uplink and downlink frequencies for each network. As their core
components are cavity filters, they retain the superb performance of this filter type, including extremely
high rejection and isolation along with the ability to handle very high output power levels. Anatech has
been designing and manufacturing bandpass combiners and separators for more than 20 years have met the most
challenging requirements. In addition to standard products available at
AMCrf.com, we can quickly build custom designs to handle any
wireless band from VHF through microwave frequencies, as well as weatherproofing for outdoor installations and
other special requirements.
