T-Mobile looking to acquire Sprint?

deafclimber said:
that is correct. in usa at&t mobilty uses 850 mhz and 1900 mhz wcdma. tmobile usa uses 1700mhz wcdma. wcdma is under GSM. wcdma can runs data and voice at same time. cdma or evdo cant run data and voice at same times.

you guys shdnt be worried about that because we all depend on data network. :)

verizon and att will roll out with LTE next few years. i dont know where Tmobile will stand since it just released 3G last friday and Sprint has delayed some times with WiMax network.

I foresee LTE will be de-facto standard for 4th Generation but I wouldn't expect to see it available for public use until after 2010-2012 and more likely will be on 700 Mhz system.

Unforunately, I wont get pleasure to work with it as ALLTEL didnt win any 700Mhz bids. But I wouldn't be suprised if we go LTE around 2012 or so.. We usually follow after big carrier.. We rather see big carrier experence with new technology before we do it to ensure the technology will success.
 
Honestly, I aint exciting about tmobile want to bid the sprint. My main concerning is between the tmobile and the sprint try to be merger. its my worrying. :)

a) Wouldn't it be SunCom you were thinking of?

It has been several months since I heard of rumours involving Deutsche Telekom/T-Mobile buying out Sprint/Nextel. I don't know how it would be. I highly doubt that T-Mobile would want Sprint Relay included in the package.

Vodafone (parent company of Verizon Wireless) probably will want get their hands on Sprint/Nextel.

a) Oh yeah, yes! thats right.. SunCom, its! thank you, brian! ;)

Honestly I have no clue about sprint/Nextel stuffs and services.

I don't know If t-mobile wanted CDMA and GSM as combo?

what is "WCDMA" stand for?

WCDMA = Wideband Code Division Multiple Access

It is not in good business sense to operate two CDMA/GSM network within same market or region. Most of the time when a CDMA carriers buy out GSM carrier's markets (typically to gain footprint or/and gain more line accounts, they converts them to CDMA network. Expensive upgrade but very profitable in long run)

I know my company brought few GSM markets in the few years ago, and required customer to get new CDMA phone within time-frame or they wont have phone service. Probably with free upgrades...

A little too late.. 3G has been around for over 3 years.. My company rolled out EVDO (3G) a little over 2.5 years ago. We just upgraded to EVDO Rev A late last year.



Yup.. They still have LONG way to go!!



220Kbps is barely 2 times of CDMA 1X data speed or approx 1/4 of average speed for EVDO rev 0.. With EVDO Rev A, the upload speed increases GREATLY which is completely POSSIBLE to use VRS over wireless phone!!



I wouldn't be suprised if they would charge almost same rate as other carrier's EVDO rate.



Like I said before, I seriously doubt they would buy sprint, they would be like shooting their own foot while sprint is still carrying Nextel.

T-mobile is very biggest company in around world, even they are serve in some European countries, such as UK and it took long time for USA to upgrade into 3G but 3G (HSPDA) has been rolling out in European countries since 2006.

T-mobile USA will upgrade into HSPDA in later time and HSDPA is more faster than EVDO, such as 3G for tmobile and O2 in UK is around 6 mbps or little over.

Why does tmobile can't use 850 mhz and 1900 mhz for 3G? Just wonders.

I'm not surprised about tmobile has rolling the 3G now, only in NYC seems too limited to me but will expands to major cities in later time.

I found out that verizon will get LTE in 2010 and att will get it in 2013, is it right?
 
Tmobile is not only company in USA to delay 3G.. Look at ATT as well..

As for other part of world, for example, Korea and Japan, they are always first and leadership in wireless. Sadly, USA will always come last..

One word: FCC... 800 Mhz bandwidth is limited to 2 carriers per markets (Band A and B).. 1900 (PCS) is newer, has many groups of bands but at MUCH smaller bandwidth compared to 800 Mhz bands. Lateness in 3G game is probably due to limited bandwidth.. Thats why 700 Mhz is used for future growth. ATT and Verizon are the BIGGEST winner in 700 Mhz game.

it was because tmobile usa bought us govt's 1700 mhz network in 2006 so t mobile usa had to wait til the govt closed its own secret network. then finally tmobile reopened 1700 mhz network. the govt wasted tmobile's time for over a year because Home Security delayed closing its network til then for some reasons.

yes that is correct. Verizon is pretty aggressive. :)

Like deafclimber said, I just noticed that att has rolling out the 3G in 2006.

Yup, USA is very big country, it taking so longer for small to medium cities to get 3G and att's 3G is currently spreading to suburb, some part of exurb and some middle cities.

Oh, got it and thanks to both of you.

I feel bad for t-mobile about waste of their time from government.

Which is more bandwidth? 1700 MHz or 850 MHz/1900 MHz?

Deafclimber, does Verizon will use GPRS/EDGE, along with LTE when LTE isn't serve in some area?
 
deafclimber said:
huh ? nope EDGE is everywhere such as rural towns but in cities there are 3G(HSDPA, UTMS, HSPA), not EDGE. HSDPA and HSPA are 3.5G.

Download theoretical peaks
Rev0 - 2.4Mbps
RevA - 3.1Mbps

Upload theoretical peaks
Rev0 - 144Kbps
RevA - 1.8Mbps

Latency (lower is better)
Rev0 - 150ms-400ms or higher
RevA - as low as 50ms in best cases
HSDPA - 120ms-400ms or higher


But again, I dont have HSPDA and really can't comment much about it. I only really can comment on EVDO side as I work with it at my job.

Keep in mind, comparing speed tests for different tech is like comparing apple and orange. Also, limiting factors is transport capacty at each cell site.. Most cell sites typically carry only two T1 for DATA only which limits to 3mbps and it SHARES with other users. Bigger sites may carry more capacty as needed. Smaller site only have ONE T1 (1.5mbps MAX)..

Also, if you are TOO close to cell site, you will get CRAP speed compared to 100-500 feets away. Reason for that, if you are too close to between 2 sectors or in between 2 cell sites, your phone ping-pong handoff between these 2 sites which affects perforance.

that is a good question but i cant answer that because there is not enough information in my wireless researching field. in my opinion, verizon's mobiles will have both LTC and CDMA in it.

same idea with att's mobiles that come with EDGE, HSDPA, GSM/GPRS.

Not in average?

When I had test with 2 previous phone, att Tilt and Sprint Mogul on my MacBook Pro, I got between 1.4 to 1.6 mbps via att's 3G and 800 kbps to 1.2 mbps via Sprint's EVDO but upload is around 100 to 300 kbps and latency is between 150 to 300 ms on both of carriers.

3G in Europe like UK is more superior than in USA, HSDPA can be go up to 14 mbps.

I disagree.. 800Mhz band has more bandwidth than the PCS. Also it is matter of how effective the carrier use the bandwidth too.

richarddeaf, i understand you work for wireless company and you think EVDO is the better. then that is fine. that is your opinion and i respect that.

however i stand correct that att does have GSM's 3G networks.

btw i work for att mobility.

google.com is our best friend that you can find more info about UTMS/HSPA. like for instance, they say HSUPA goes 7.5mbps down and 2.0 up.

i am aware of that. i just say in general way. they are no diff. if he questions the size. then i wud know, but really there is no diff. like 1700 is better than 1900. it depends on what FCC authorizes what frequencies wireless carriers can get.
