Stuck with 1xRTT - Good, Bad or Ugly?

I had a cable connection which is much missed now.  I moved and recently signed up for Sprint wireless for my home connection.  The options for my new location were very limited, dial-up  :uglystupid2: Wildblue/Hugesnet [geek] or Sprint Wireless  :undecided:

I connect with a Sierrawireless Compass 597 through a Cradlepoint MB1000 router.  Is this all I can expect with this type of connection?

Sadly yes...Does anyone know if AT&T's upgraded EDGE speeds work on the wireless cards too? Because if your area has AT&T's upgraded EDGE you could squeeze 200k out of that connection. I know I get that on my Iphone anyway.

I checked AT&T but they don't have coverage in my area.  I've been told that Centennial Wireless has the same wireless in my area but at about half the price of sprint.  I would have to break my contract but I would make up that fee in about 6mos of service with Centennial. 

I heard a rumor that Sprint is working on a EVDO signal which would travel 20 miles radius vs. the service they have now.  Anyone else hear something to that effect?

Welcome to the forum!

By the way, Centennial has the wireless cheaper, but did you see the limit on how much you can download? Its like 15-20 mb. I would keep sprint or go to verizon if they have coverage in your area.

EDIT- I just looked it up. I guess that was only for nationwide or whatever. Local is "unlimited" =)

I found some nice Info on another forum (i'm not sure if I can post the site here) posted by northform.

CDMA is currently the dominant technology in the United States. CDMA works by having all of the calls transmitted on the same frequency at the same time. It identifies different calls by code. This, theoretically, gives CDMA an unlimited capacity under perfect conditions, but of course CDMA does have a limited capacity. There is only a certain ammount of noise that a channel can accomodate before the system and your phone can't recognise one signal from another. If you doubt the limitations of CDMA ask some angry Sprint customers in these forums complaining of network busy signals. Getting back to CDMA, it works to limit this noise by having a phone transmit at the lowest possible setting that will get the call through. One of the factors that determines how much power is need to transmit is distance from the tower. All phones have to take this into consideration. The other factor that only CDMA-type systems have to account for is the number of callers connected to the system. This is an example that one of the mods here (bobolito I believe) used: Say one person is 1 mi. from the tower using 1 watt to transmit. He is the only one connected to the system. Then another person joins the system from 1/2 mi. away transmitting at 1/2 watt. The person further away would have to up his transmition power so that the closer person's signal didn't totally cover his. As more people join the system the current people have to continue to up their power so that their call isn't drowned out by the new ones (think of people at a party talking. The more people talking the louder you're gonna have to talk). Also, the more people who are connected to the system means that there are more distances and more levels of transmitter power and the closer people are starting higher. Now there are 1000s of people connected and the people at 1/4mi. are using 1 watt, the people at 1/2 mi. are using 2 watts, and the people at 3/4 mi. are using 3 watts and the person at 1 mi. looses his connection because it is drowned out by the closer voices and he can't transmit more powerfully (talk louder) than 3 watts. In this way, CDMA coverage is variable in a way that TDMA/FDMA (and systems based on those principals) aren't. Beyond calling, that oversimplification shows how CDMA does have limitations even if everyone is at the same distance using the same transmitting power. 1xRTT - the 2.5G voice/data solution for CDMA - is currently deployed by Sprint and Verizon in certain areas. A lot of the times the carrier has implimented 1xRTT data, but not voice since the data is immiedately apparent. 1xRTT voice does offer some improvement in call quality, but not much and is still a tiny bit behind GSM's EFR codec. 1xRTT data improves data rates to a theoretical 144Kbps, but again, in reality, it will never exceed 64Kbps. After 1xRTT comes 1xEV-DO (data only/optimised) and 1xEV-DV (data/voice). 1xEV-DO has a theoretical 2Mbps, but will be 384Kbps in the real world just like EDGE and wCDMA.

This shed a lot of light for me and tells me that if I'm looking for a data connection vs. voice then it looks like Sprint is what I want.  Getting back to the topic of this post my connection isnt good and compared to dial up it isnt bad but trying to play online games with it..it sure is Ugly.

So i guess from here what I should be trying to do is hit that 144Kbps that northform posted as the max, from the test I did from this site i've already passed the 64Kbps that he said "it will never exceed".
