Conversation about Sprint Moving to UMTS

Everyone, meet Josh... AJ -
Conversation about Sprint Moving to UMTS
WiWavelength replied to telefunken's topic in Network, Network Vision/LTE Deployment
Sure. The source is me in the Google "time machine" from about seven years ago... http://www.howardforums.com/printthread.php?t=788064&page=2&pp=15 AJ -
Conversation about Sprint Moving to UMTS
WiWavelength replied to telefunken's topic in Network, Network Vision/LTE Deployment
That was limited to American Personal Communications (APC) dba Sprint Spectrum in Washington-Baltimore about 15-20 years ago. It is a long story, one that I have written up many times previously... AJ -
Network Vision on 1x Only Towers
WiWavelength replied to zodiac12345's topic in Network, Network Vision/LTE Deployment
SMR 900 MHz is currently in use for paging, dispatch, and iDEN 900. Maybe there will be discussions with the FCC following the iDEN shutdown but not until then. Plus, if you want "low data rate" usage, well, you already have paging in the band. So, there you go. If you want broadband operations instead, you would have to kick out all other SMR 900 MHz users. To understand the interleaved nature of the SMR 900 MHz band, I think that you really need to read the following thread: http://s4gru.com/index.php?/topic/390-how-much-of-the-900-mhz-band-being-used/ AJ -
Network Vision on 1x Only Towers
WiWavelength replied to zodiac12345's topic in Network, Network Vision/LTE Deployment
Nope. Sprint transferred its BRS/EBS 2600 MHz spectrum to Clearwire about five years ago. Clearwire then wholesales WiMAX to Sprint and other operators. AJ -
Network Vision on 1x Only Towers
WiWavelength replied to zodiac12345's topic in Network, Network Vision/LTE Deployment
A licensee cannot just unleash licensed spectrum for unlicensed access. That would make the licensee liable for any improper or illegal use of said spectrum. Plus, as I mentioned previously, almost no one these days wants narrowband, interleaved spectrum. AJ -

BRS 2600 MHz is attributable to Clearwire, not Sprint. AJ -
iDEN and CDMA2000 are two very different animals. iDEN uses 25 kHz channels. CDMA2000 uses 1.25 MHz carriers -- the same bandwidth as 50 contiguous iDEN channels. Coordinating one 25 kHz channel here and there across the international boundary is feasible; coordinating 50 contiguous channels is downright impractical. AJ

COUNTDOWN!!! Nextel iDEN Shutdown
WiWavelength replied to S4GRU's topic in Network, Network Vision/LTE Deployment
Stop, drop, shut 'em down, open up shop. Oh, no, that's how Ruff Ryders roll. AJ -
Yes! Loose the dogs of war, EV-DO, and LTE. AJ

Report: Sprint Deal Unlikely to Get Past Clearwire Shareholders

Maybe there would be a few fries left in the bag for you. AJ -
Report: Sprint Deal Unlikely to Get Past Clearwire Shareholders
WiWavelength replied to cletus's topic in General Topics
If Clearwire were to go into BK, that would be quite the whopper. It could cause a feeding frenzy, but I wonder who would be left holding the bag. AJ -

Report: Sprint Deal Unlikely to Get Past Clearwire Shareholders
WiWavelength replied to cletus's topic in General Topics
Megaphone. Maybe that would be a good rebranding for Sprint if Ergen somehow wins this bidding war. AJ -
First of all, maximus1987, both CDMA1X and EV-DO are "3G." Roaming agreements do not generally make a distinction between the two. Many official Sprint PRLs contain EV-DO ACQ indices for most/all SIDs. So, the issue is not the airlink but the actual data roaming usage. As long as users do not violate Sprint's Ts and Cs by exceeding the 300 MB monthly data roaming quota, then CDMA1X or EV-DO is immaterial. Second, my post that you quoted was in response to another post, which actually turned out to be citing data usage of a large multi user account on VZW. I did not appreciate that member posting those stats as almost some badge of honor, but that data usage was not due to a single user, nor was it on Sprint. Thus, it has practically zero relevance here. AJ

COUNTDOWN!!! Nextel iDEN Shutdown
WiWavelength replied to S4GRU's topic in Network, Network Vision/LTE Deployment
Yeah, those Southerners do not think highly of broadband. They want their frequencies to remain separate but equal. AJ -
COUNTDOWN!!! Nextel iDEN Shutdown
WiWavelength replied to S4GRU's topic in Network, Network Vision/LTE Deployment
The irony regarding anti iDENism is that the stronghold for iDEN long has been and still is the South. AJ -

Network Vision on 1x Only Towers
WiWavelength replied to zodiac12345's topic in Network, Network Vision/LTE Deployment
Actually, SMR 900 MHz is based on 12.5 kHz FDD channelization. Nextel paired adjacent channels to deploy iDEN 900. Some uses still require narrowband spectrum. Paging is one, and refarming the SMR 900 MHz band would require relocating a big portion of the paging industry. AJ -
Sprint to buy spectrum, customers from USCC
WiWavelength replied to bigsnake49's topic in General Topics
It is being leased back to USCC for a transition period. AJ -
Network Vision on 1x Only Towers
WiWavelength replied to zodiac12345's topic in Network, Network Vision/LTE Deployment
No, you cannot look at an unlabeled frequency, such as "900 MHz," and jump to a conclusion. The GSM 900 MHz band does not exist in North America, but the ISM 900 MHz and SMR 900 MHz bands do. The former is an unlicensed band that has been used for cordless phones, garage door openers, etc. The latter is a paging band that Nextel adapted for iDEN for added capacity. No, it is not useful for any broadband operations. As for selling it, who wants to buy it? Likely, no one. Paging and iDEN 900 took care of that. AJ -
The only way that is possible is if their MSCs are harmonized. And I am not aware of that elsewhere, so it seems out of place here. I suppose one possibility is that -- because this area outside of Charlotte is a former affiliate market -- AirGate PCS could have contracted to use USCC's MSC as its own. But even if that were the case, I would have expected Sprint to take that in house with its affiliate acquisitions several years back. AJ

Straight talk offering LTE on the Sprint network w/ GS3
WiWavelength replied to coorsleftfield's topic in General Topics
I am not quite sure why you are asking. WCS A/B blocks are each 5 MHz FDD, hence already paired. WCS C/D blocks are 5 MHz TDD, but those are the blocks presently being sacrificed as de facto guard bands to protect adjacent SDARS operations. So, since the WCS A/B blocks are those being pressed into service for LTE in a few years, FDD operation was already established. By purchases from or acquisitions outright of BellSouth, NextWave, and Comcast, AT&T has consolidated most of the WCS band under its own control. The largest outstanding licensee is, poetically enough, Sprint. AJ
