  1. Well, we have written and posted about the differences between RSSI and RSRP a lot. But if you have not yet come across that info, I suggest that you start with the following article and thread: http://s4gru.com/index.php?/blog/1/entry-308-rssi-vs-rsrp-a-brief-lte-signal-strength-primer/ http://s4gru.com/index.php?/topic/2040-bars-lie-for-lte-signal-strength-how-to-determine-your-actual-lte-signal-strength/ AJ
  2. I suggest that you do get used to it. Because of entrenchment, some things are practically unchangeable. I know this from a dozen years of researching the wireless industry. I have long publicly and politically argued against the stockpiling of spectrum, especially by the duopoly, and that has changed nothing -- other than to change me into a jaded, angry wireless veteran. Trust me, you do not want that. AJ
  3. Are you not aware of the differences between CDMA1X RSSI and LTE RSRP? You cannot simply compare the signal strength numbers directly. AJ
  4. If people want it on their own schedules, that is time shifting, which does not work with LTE Broadcast. Then, we are back to individual streams. So, yeah, that will go a long way toward eating up our capacity and congesting our networks -- again. It just blows my mind how people seem to have nothing better to do with their brains than to passively consume streaming content. I guess we should move the "boob tube" nickname from the TV to the smartphone. AJ
  5. They spring forth fully formed from Dan Hesse's bald head. But that gives Dan an enormous headache, so he can birth only a few site workers per day. AJ
  6. Well, no, your facts are a bit off. Qualcomm had the Lower 700 MHz D block 6 MHz unpaired (UHF channel 55) nationwide and the E block 6 MHz unpaired (UHF channel 56) in New York, Los Angeles, Philadelphia, San Francisco, and Boston. Thus, that was 6 MHz nationwide plus 6 MHz in only five markets. And Qualcomm sold that spectrum to AT&T three years ago. Now, it sits unused because AT&T cannot yet figure out what to do with it, since it is unpaired, fit only for TDD or carrier aggregation operations. Qualcomm, on the other hand, had put it to good use for several years, though MediaFLO light up was delayed in some markets due to postponement of the NTSC sunset, ATSC transition. But MediaFLO was a damn good idea, offloading popular simulcast streaming content from the macro cellular network onto a broadcast network. With EV-DO and W-CDMA, it made no sense to have thousands of people around a metro each simultaneously streaming the CBS Evening News, ESPN Sports Center, etc. It still makes little sense over LTE, even with eMBMS LTE Broadcast, as that still takes up valuable capacity on an LTE carrier. That MediaFLO failed is not really Qualcomm's fault. The idea just came to market too soon. Most wireless subs were still on flip phones with screens that made watching mobile TV barely palatable. Now, with large screen smartphones and tablets taking over the market, mobile TV is likely to take off with them. Then, you mentioned cable/satellite companies. Cable was SpectrumCo (Comcast and Time Warner) and Cox, which together controlled 20 MHz of AWS-1 spectrum nearly nationwide. Cox actually put some of its spectrum into use, as it built a wireless network in a few of its markets. But Cox shuttered that network a few years ago, as it could not compete with the incumbent operators. Meanwhile, SpectrumCo never did anything with its spectrum. Regardless, both SpectrumCo and Cox sold off their spectrum to VZW two years ago, so that point is moot. As for satellite, Dish has 40 MHz of AWS-4 spectrum nationwide, but AWS-4 is not the same thing as AWS-1 -- do not conflate the two. AWS-4 is terrestrial spectrum now, yet it was converted from satellite spectrum only in the last year. To do anything with that spectrum only recently authorized for terrestrial use takes standardization, planning, and deployment -- all of which take years. Finally, the "scrambling over spectrum" has little to do with current needs or capacity. Operators just want to stockpile spectrum for future use and keep it out of the hands of competitors. So, a lot of spectrum sits around unused. Get used to it. AJ
  7. No, that is not accurate. To what spectrum are you referring? AJ
  8. Nah, I highly doubt that Warren G could "regulate" the Super-G. http://www.youtube.com/watch?v=ODFeUeNcvy4 AJ
  9. I suppose I need to do some scans of Sprint, VZW, and Cingular coverage brochures, circa 2000-2003, that I have archived somewhere. Sprint native footprint is nearly the same now as it was then. But VZW and Cingular (AT&T) have used their monopoly money to buy up everything else in site -- pun intended. Many of you youngsters lack the age and experience to be aware of that. AJ
  10. Why limit it to 5G? Go ahead and deploy Ali G. AJ
  11. Ooh, BandRich. I would be a proud owner of that one. AJ
  12. They spin the wheel of fortune, read tea leaves, or rely on voodoo. AJ
  13. CDMA1X 800 is "turned on" on a far greater number of sites than you know, than even we know. But just because CDMA1X 800 is active on a site does not mean that you will use it -- unless you actually need it. Then, your handset or the network will bump you down to CDMA1X 800. Think of CDMA1X 800 as something of an invisible safety net. AJ
  14. And now that it is totally on an off topic rampage, this thread is probably going to "prison" soon... AJ
  15. Kansas City is a majority KU basketball city, and KU plays in KC roughly five game per year. So, nope, you are dead wrong. KC most definitely claims KU as its own "pro" basketball team. AJ
  16. Which team? We have little interest in an NBA team in Kansas City. We are a college basketball town. And in addition to major pro sports, we also have arguably the most accomplished major college sports team in the region in KU basketball. No, we run the show in these parts. You Iowans, Nebraskans, and rural Kansans come to us for the show. AJ
  17. No idea. Not a recognizable player. Does he play for the NBA D-Leage Iowa Energy, your "major" pro sports team? If you have not noticed, Kansas City has a bit of a superiority complex to Wichita, Omaha, and Des Moines. AJ
  18. Yes, here in the Kansas City area, we actually have major professional sports. But we understand that, up there in Aksarben, you have to hang your hat on the Cornhuskers as your "pro" team. AJ
  19. AT&T is reportedly the operator that started having engineering screens removed or access blocked. AJ
  20. An SVDO capable device might be able to pull off a CDMA1X -> EV-DO handoff or even maintain simultaneous CDMA1X data and EV-DO data connections. But SVDO capable devices were few and short lived. Otherwise, no, CDMA1X -> EV-DO handoff is not possible because CDMA1X requires a constant connection. The baseband has no downtime to scan for another airlink. AJ
  21. I guess too long equals too much security. Ha! Speaking of security, should we move this thread behind the curtain of the sponsor section? If not, then search engines will index this thread, including the group ID and password. AJ
  22. Traditional affiliates do own their contracts. AJ
  23. That is probably because Robert loves fried chicken does not mean he loves KFC. AJ
  24. No, because he plays in the AFC. I am fine with the judge being lenient. Sentence him to 35 years but eligible for parole in 15 years. By then, he will be over 50 years old and no longer able to play. AJ
