LightSquared Says It Has Cheap and Easy GPS Fix
LightSquared today announced that it has figured out an inexpensive way to solve the GPS interference issues created by its L-band Long Term Evolution 4G mobile broadband network. LightSquared said it signed an agreement with a company called Javad GNSS, which "can be adapted to work with high-precision GPS devices including those already in the agriculture, surveying, construction and defense industries." Javad GNSS has taken its equipment and refreshed the filter and amplifier settings so that they are compatible with the 10MHz swath of spectrum LightSquared plans to use to operate its LTE 4G network. LightSquared says the fix is so simple and inexpensive that it will not increase the price of consumer equipment. The Javad GNSS equipment is expected to be ready for testing late this year, with deployments expected in the first half of 2012. LightSquared has been battling the Federal Communications Commission and the GPS industry for the better part of a year over its planned network, which many believe interferes with GPS signals. The FCC has told LightSquared that more testing is required before a final verdict can be rendered.
T-Mobile Says It Will Start Using 600 MHz Spectrum This Year
"T-Mobile now has the largest swath of unused low-band spectrum in the country," said T-Mobile CEO John Legere about the company's 600 MHz auction winnings. The company successfully won an average of 31 MHz (ranging between 20 MHz and 50 MHz) of the 70 MHz low-band spectrum auctioned off by TV stations and the FCC.
Samsung Reveals Exynos 7870 for Mid-Range Phones
Samsung today announced the Exynos 7 Octa 7870, a new mobile processor that targets mid-level handsets. The 7870 is manufactured using Samsung's 14nm FinFET process and consumes 30% less power than the previous generation 7xxx chip.
Qualcomm Develops 5G Test Platform
Qualcomm has created what it calls a prototype 5G system and trial platform. The 5G New Radio (NR) prototype is able to function across a wide range of spectrum bands, primarily below 6 GHz, and can achieve multi-gigabit per second data rates and low latency.
T-Mobile Rolling Out LTE-U
T-Mobile today said it is beginning to upgrade its 4G network with LTE-U this spring. LTE-U allows LTE to operate on the unlicensed spectrum in the 5 GHz band, which is typically reserved for WiFi.
I found a picture for the non-techy out there
Look at the graphic halfway down the page. The orange 'McDonald's" symbol on the left is where LightSquared wants to broadcast. They have compromised to only using the left lobe labelled "10L" for now.
The Yellow is a higher-grade GPS reciever, and the Blue is a modern-day consumer GPS reciever (Cell phone, Garmin, TomTom, etc.)
The Black is the new (not-stupid) JAVAD GPS filter design.
The Yellow and the Blue are only "supposed" to work between 1559 and 1591 MHz (labeled at the top of the graphic) but they built such crappy hardware that they're failing to stop accepting input from the "10...
But I noticed its from Lightsquared (hardly a reliable source in this issue)!!
The facts are that GPS exists and is in use TODAY. Bandwidth overlap and leakage are KNOWN variables and should not have come as a surprise to Lights...
what about the rest of us GPS users?
What about my GPS? Is this technology going to be applied to LightSquared's equipment so that it will not interfere with ANY other GPS equipment, or is it going to be provided or installed on major GPS equipment/groups/entities in order to overcome the interference from LightSquared?
Anyone have any clarification?
It's not clear to me in this story, what this means to ME...
