Why are they doing that? Incompetence or dishonesty?

Companies ALWAYS say "may". "May experience drowsiness" etc. Its a psych thing.

Friends speed test wasn't able to START on iphone 5 while my VZW iphone 4 got 1mbps. Marketing is gonna get people onto the network but if they can't load Facebook, they're gonna leave very quickly. Sorry but network matters.

That's the cumulative capacity of channels in 5MHz FDD not even the peak theoretical rate of ONE user. That's across 25 (said AJ) EDGE channels. That's 480kbits/sec per channel.- 4,425 replies

Carriers are deploying LTE for CAPACITY not individual throughout. They deployed it to keep up with demand and have decent data speeds per user, not to give each user 50mbps average speeds. Not sure if you were implying that Sprint might be able to compete with ISPs but don't. A cell tower is shared so the download speeds are divided by number of users. Take Netflix stream, 2.6-3.8mbps, multiply by 100 users and what do you get? More than Sprint will be able to support for a long time.

Neither TMO not Sprint will get into a bidding war with ATT and Verizon. There will be an effective carve-out for non-ATT/VZW carriers but once that is consumed, the rest will be bid up, up, up by VZW/ATT. No duh I don't want duo to get that most. I also want marshmallows to grow on trees. Sprint and TMO can aim as high as they want to but it's tough to argue with 191bil and 146bil market cap. And if the reverse auction doesn't raise enough spectrum, guess who's gonna it all? Mr 191bil and mrs 146bil.

There's always gonna be some people who only use dumb phones AND M2M always need the lowest cost solution. That means WCDMA+ will still be useful to TMO. Think of the data capacity in 5 MHz FDD: for wcdma vs EDGE: 21mbps vs ???1mbps???- 4,425 replies

They don't need 10x10 600. ATT is running 5x5 on 700 in Chicago so I think Sprint will manage with 5x5 600 in addition to PCS once its all reframed. Why do you think they need 10x10 in 600? Even if they use 800 entirely for voice, they still don't need 10x10 LTE. The only people who are only gonna be within reach of 600 or 800 are: deep within buildings and way out in country. In both cases, its not gonna be a lot of people PER SECTOR.

Up above (I think) Neal said WCDMA+ will be useful in freeing up voice capacity so that GSM can be replaced by WCDMA+ as the new baseline for M2M.- 4,425 replies

If they refuse to make more CDMA, what choice will Sprint have? With Verizon's 100mil gone, it's a losing game for Sprint. Qualcomm, if it can, will raise rates for CDMA chips to make up for !poof! departure of 100mil potential customers. Who else in the world is still marketing CDMA service? As an engineer, it is sad to see an inferior voice technology win out. According to http://d1sxb0xfyrci7y.cloudfront.net/asset_files/0001/5119/99f87820-4045-012d-1e0f-123136004881/v6/1XAdvanced_Web_08162011_NA_EXT_original.pdf pg 12/16, 1xA has 4/2.1 = 1.9 the capacity of VoLTE. Then again, the network-side engineers must pine for the day when they only have to deal with one network technology.
