Re: [JUL 12] *11 Radios Available* Updated Touch Pro CDMA Radio Archive Thread
Has anybody found a good radio that works good in the Northern VA area?? If not then time to play with the radios.. lol

Re: [JUL 12] *11 Radios Available* Updated Touch Pro CDMA Radio Archive Thread
At risk of sounding like an elitist prick, which honestly, I don't intend to be, but I'm honestly not sure how to say this without sounding at least a little rude:
Please bear with me, and try to understand the message I am trying to convey, as no offense is intended. If you really have little to no clue about how radio systems work, or how to test them, *please* do everyone a favor, and don't post your random imaginings as to how well a specific radio rom works. It is just misleading, and leads to *more* confusion for those who don't really understand any more than you do. Now, I don't expect everyone to be an expert on IP radio systems or anything, but if you are judging signal, reliability, or really just about *anything* based solely on the signal strength bars displayed on your handset, then you really should not be making recommendations to anyone. Even Sprint CS will tell you how nearly meaningless those bars can be, especially if you have no idea how they are actually generated. (They normally don't measure actual signal quality, or sadly even signal strength, but are instead based on an algorithm derived from the amount of amplification needed by the handset) Likewise, online speed tests are really not a decent measure of even *wired* broadband, and are certainly not a measure of radio reliability. Even under the best circumstances they can only be a guideline, but in reality, there are so many outside factors involved, that they are fairly meaningless as far as determining how one radio performs compared to another without doing 1000s of tests with each radio over a period of time, averaging the results, and comparing them to each other, and even then, you really cant be sure that things such as seasonal usage drift, or network load due to a hot new device were not to blame for any differences, unless you do your tests on every radio you are testing every single day using multiple devices, or reflashing repeatedly. __________________________________________________ ______________ If you don't really understand the mechanics involved in radio performance testing, what you *can* do that *WILL* help quite a bit, is just use your device normally, in as many different places as possible, and report how well in general the radio you are using seems to perform compared to what you are used to. Reliability, heat generation, battery drain, and so on. For those that would like to be educated in testing processes, I can try to write up a guide, when I get a chance, if Strra wants to put a link to it in the first post. However, the majority of my current wireless experience comes from when I helped manage and maintain the WiFi network sites of a local hotspot ISP so, it would probably be better if there is someone available that is an expert on *mobile* wireless networks, and EVDO data systems in particular to do it. In the meantime, I'll see if I can find a post I saw somewhere that had some easy guidelines, and re post it here. |

Hello fellow radio testers. I'm gonna try and put up a guide here soon to let you know about some other testing scenarios/guidelines in which I think would be helpful for everyone here to figure out what works best for each person individually. In the meantime let me find a link that will give everyone an idea of what I'm talking about. See? Easy peesie. No thanks needed. Last edited by obamaftw08; 07-13-2009 at 03:26 AM. |

Oh believe me, I've done my fair share of fielding numerous tech questions. However, if you're going to criticize a vast majority of the userbase here and not give much in return, at least do it with the understanding that if you're post isn't substantial in any way other than to be heard, you're not going to get a lot of applause.

Re: [JUL 12] *11 Radios Available* Updated Touch Pro CDMA Radio Archive Thread
I swear, sometimes the search function of these forums is so useless.
I've wasted way too much time looking for that guide I mentioned I had seen, I should have just taken the time to write my own But now its almost 2:30 am here, and I was tired before I got started... Here is one pertinent post I found however, which you can probably get by with until I can write a more comprehensive guide. Quote:
Typically, with EVDO, you want to have less than -80dbm for decent throughput, with top end being reached somewhere below -70dbm and anything below that giving lower latency, and higher stability. In real world usage, -50dbm is about good as you are ever going to get, and in most cases, not bloody likely, lol. Although, I have actually been able to achieve -46 to -47 by standing at about a 30° angle from a tower, about 60 yrds away (because of the physical characteristics of typical radio towers, you will actually get *lower* signal strength directly underneath (or above, lol) due to the conical umbrella they broadcast, I got around -65-67 standing at the base of this particular tower, for example) Also remember, even if you were to get say, -55dbm, which is pretty much incredible signal strength, (might as well plug your phone directly into the tower, ) your throughput can be limited by many other factors, such as the backhaul of the tower, and network load. So, while your phone might be able to communicate with the *tower* at 3.1mbit your network might not be able to provide that. Of course, if it doesn't, there is nothing really wrong with complaining to your provider about it, to give them a little prod to induce them to improve their infrastructure |
