Oh, look, AT&T is whining again:
AT&T Inc. (T) Chief Executive Officer Randall Stephenson said Washington needs to figure out how to clear a regulatory logjam that’s hampering wireless growth and forcing companies to raise prices.
The industry is waiting for the Federal Communications Commission to decide on Verizon Wireless’s proposed $3.6 billion partnership with cable companies, including Comcast Corp. (CMCSA) The review of that agreement, announced in December, is holding up related deals for spectrum by AT&T and others, Stephenson said.

The popularity of the iPhone and other smartphones is putting pressure on existing networks, prompting wireless carriers to seek more capacity in crowded markets. The FCC has to sign off on each transaction, and its rate of decision making can’t keep pace with the industry’s evolving needs, he said.
“The industry is just kind of stuck and we’re all sitting here watching Verizon-Comcast waiting to see what happens,” Stephenson said yesterday in an interview at Bloomberg headquarters in New York. “You have got to make sure we put spectrum in the market. They need to become liquid spectrum markets.”

If I'm reading the tea leaves correctly, FCC will force Verizon to divest their 700MHz A&B blocks and their own AWS spectrum concentrated in the eastern part of the country. AT&T will be the recipient of most of the 700Mhz and AWS spectrum with T-Mobile and Metro picking up the rest.

Its funny. But there is a sad truth underneath all the humor. AT&T is so rediculous. And their anti-competitive nature shows through more and more every time they speak. They are just becoming more despised in the eye of the American consumer. Their punitive raising of prices is going to backfire on them. Stupid.

It will only backfire on them if Sprint offers an alternative. Maybe in a year or two when they have their NV substantially complete.

I still think that their best chance is to offer data only packages for business/individuals for both fixed and mobile/nomadic access. They don't need retail access, they can do it over the net and maybe through Radio Shack. Combo desktop modem/MiFi type devices. They need to be part of NV, end of story.

Sprint's Iyad Tarazi said at CTIA that Sprint plans to introduce Airave hardware that supports CDMA1X 800. Does anyone else see the problem with using stronger propagation and limited bandwidth SMR 800 MHz spectrum in femtocells?

Nothing different than using a 1900MHz femtocell except the interference problems extend to a larger radius. Interference cancellation and radiated power control has to be more sophisticated than the original airave.

I think its funny on those coverage charts that the descriptions are 'good - better - best - excellent', nothing negative there.
Triumph of marketing over engineering

Really, MetroPCS, Leap and USCC and a few others should merge and create a 5th national competitor. Maybe even get Sprint to host their spectrum.

How many customers would the combined company have if they did merge?
Approximately 42Million customers.

I think it will be better if Sprint acquired them. Much easier to migrate them to Sprint's prepaid brands. Keep the PCS spectrum and sell/exchange the AWS spectrum to T-Mobile/Verizon.
The other idea is to let them and Cricket become MVNO's of Sprint in exchange for their spectrum, with appropriate discounts, of course.

Deutsche Telekom AG (DTE) is discussing a merger of its T-Mobile USA unit with MetroPCS Communications Inc. (PCS) as it reviews options for the customer-losing business, according to people familiar with the matter.
Deutsche Telekom is considering a stock-swap transaction that would give the German company control over the combined entity, which would be publicly listed, said two of the people, who declined to be identified because the talks are private. Other options include an initial public offering or an outright sale of T-Mobile USA, the people said, adding that Deutsche Telekom is also in talks with other companies. MetroPCS shares jumped as much as 29 percent in New York.
How about Cricket becoming a preferred MVNO of Sprint in exchange for Cricket's spectrum? Sprint doing the same for Metro?

Agreed. Small and medium sized smartphones are disadvantaged with MIMO larger than 2x2. Even 2x2 is tough in those little guys with an ever expanding frequency set.
I'm looking forward to a larger iPhone being released. All of a sudden these iPhoniacs who loved small phones will miraculously love larger devices. Its going to be funny.

The other thing that needs to be considered is that MIMO is most effective in urban environments rife with multipaths. Not much good on a flat, suburban state like Florida. I have seen some good work on innovative antenna designs that are dynamically tunable to different frequencies. Also tree-shaped antennas where each branch+part of the trunk is tuned for a different frequency.

All things being equal in the way its deployed, HSPA+ does not out perform LTE. I guess you could argue maybe on the device side there are better performance attributes like battery life and device availability.
Robert via Kindle Fire using Forum Runner
It definitely has advantages on the basestation side where you can deploy up to 8x8MIMO. Not so clear on the device side, where if you can squeeze 2x2 MIMO you're in business. Maybe on the tablet or laptop side, but I don't see anything more than 2x2 on an iPhone sized handset, do you?
-
The future is LTE. However, I don't understand T-Mobile's rush to join the parade. They could wait couple of years and get a mature network built cheaply, rather than been on the bleeding edge. HSPA+ has plenty of headroom for them.
Both Verizon and Sprint have to move to LTE because of the lack of headroom on EVDO. Neither AT&T nor T-Mobile needed to move that fast. Oh, well...

So WiMAX would be excellent in a low humidity environment such as space?

Does anybody know if the cablecos have sold off their Clearwire holdings? I would like to see them offer some fixed modem internet access. I would not mind having them as a a backup internet provider for my wife's office.
-
I think those speeds are for stationary terminals, not mobile. Not many phones can accommodate 8x8 MIMO. But it does brings to mind that Clearwire can go after home internet connections or even bundle home and mobile access. Now, can you imagine how much power the radio amplifiers will draw for a 100MHz channel? Yikes!

Does anybody know if Sprint will participate in this auction? Basically the FCC wants to subsidize rural access to cell services (3G & 4G access) and is looking for the lowest cost producer.
-
I think there's probably just one antenna for 800MHz (SMR spectrum) and 850MHz (Verizon/ATT cellular frequencies). I thought I had read somewhere that Qualcomm was going to support just three sets of frequncies (antennas/preamps).
-
Does anybody know whether they're adding CDMA800 to very NV site or every other or what arrangement are they using?
-
You can definitely use the WiFi antenna for Clearwire frequencies. Is it optimal? No, but then very few things are. PCS antennas in handsets are tuned to the middle of the PCS band and not for each block (A-G). Simple antenna design for cellular systems is full of compromises. Try sticking 4-way MIMO antennas in a 700MHz handset! According to the formulas for a 750MHz center frequency each of them would have an optimal length of 40 centimeters (15.75") and there would be 4 of them. Try and fit that into a 4.7" handset!

LTE Carrier Aggregation is not the panacea its being heralded. It causes significant device battery drain and prevents the use of MIMO in smartphones.
I personally think deploying 5x5 LTE carriers is more than sufficient with Sprint spectrum. It performs more than acceptably and exceeds the needs of 95% of customers. Maybe even more. Sprint's 5MHz LTE is faster than most of their customers home ISP's! And it is way faster than smartphones can even appreciate and handle.
I think customers will really be more than happy with 10-15 Mbps LTE speeds. Any faster than that is just a pecker size contest. Sprint should reject carrier aggregation and just focus on more carriers (and spectrum) for capacity. Clearwire should also avoid CA and just deploy 20MHz TD-LTE carriers. They will exceed VZW speeds. That should be enough for bragging rights.
What would you rather have? A fast Sprint LTE device with a battery that lasts all day? Or a blazing fast Sprint LTE device with carrier aggregation that will last half a day?
For me the choice is easy. No carrier aggregation. I just think consumers are going to reject speeds beyond 10-15Mbps soon. It will just be bragging rights on paper only. It will have no real usable difference for smartphone users.

Robert, do you have some links on the effect of carrier aggregation on MIMO? I know that MIMO is a challenge at 700 and 800MHz because of the size of the antennas and the lack of real estate on smartphones, but I'd like to read the technical reason on why you can't have MIMO and carrier aggregation at 1900MHz.

I was borrowed my frinds Verizon LTE phone to use around Orlando and was not impressed with the density of coverage. While sppeds were excellent were there was coverage, the coverage was lacking overall. I hope that Sprint does a better job covering their markets than Verizon. If I was a cautious man, I would say stay away from anybody's LTE until the end of 2013.
-
I'm very happy that Clearwire is finally seeing the light and cooperating with Sprint. They went way overbuilid with their deployment of Wimax instead of filling in capacity holes for Sprint. All those additional sites cost money to operate.
On the other hand, a lot of the sites can accommodate both wimax and LTE at the same site with minimal additional expense.
I still think that a Dish/Sprint merger makes sense.

Duffman, I think it's free for their subscribers. I have also heard that cable MSO's are talking about free roaming on each other's networks.

I agree with you. Those leases cost money and they have not exactly been swimming in the dough. However, they could sublease them to other interested parties. I also agree with you on having more than 40 Mhz channels. The power bill alone for running more than 40MHz channel is going to be huge. Not to mention having to pay an arm and a leg for wideband amps.
