There are many factors in determining how far a signal will propagate from a tower. Just because a tower is high does not mean that Sprint is at the top of that tower. I live next to a boomer, and Sprint is way down on the tower. Also, you may be between two sectors. There are three sectors of antennas on each tower (sometimes only two). If you are positioned perfectly between two sectors, you could have diminished signals in some instances. Downtilt. Antenna panels are tilted toward the ground, based on RF engineering design calculations. Sometimes steeply. The steeper the downtilt, the less far the signal will travel, but the more concentrated the signal will be within its coverage area. Physical Obstructions. You may have physical obstructions... large buildings, grain elevators, water towers, forests, swamps/marshes between you and the site. All are bad for RF signals. You may be in a slight gully/depression that may not be noticeable to you, but takes you out of RF sight to the tower. RF Interference. Some locations just are bad locations for RF. They may have interference. Power plants, large power transmission lines and electrical yards are known to cause interference. And if one of these interference sources is between you and the site, it can cause problems. So, there are no easy answers. Robert

No. Sprint is not tracking those in a place where I can access to them. But the Premier Sponsor maps do show the dates backhaul is scheduled to arrive at every site in the First & Second Round Markets. Robert

Sensorly's LTE coverage maps are down for all American carriers this morning (including Sprint). WiMax and 2G/3G seem to be working fine. Will this be fixed today? Robert

Airaves do not currently work with 4G. All handle 1x voice, and most handle 3G EVDO data. It will probably be awhile until LTE is available on an Airave. Robert via CM9 Kindle Fire using Forum Runner

I am not aware of anything in the LTE-A standard that would improve its fragile signal propagation. If anything, the more data we cram into a signal, the stronger signal it takes to deliver it. LTE-Advanced does not offer any spectral efficiencies over LTE. It just allows faster data rates through increased MIMO support, carrier aggregation and other technical modifications. LTE Advanced is just LTE Release 10. Sprint is currently deploying LTE Release 9. It can upgrade to Release 10 with a software upgrade. But until carriers/OEM's start selling devices that can support 4x4 MIMO and/or Carrier Aggregation, there will be few benefits to the consumer for LTE-A networks. And the biggest stumbling blocks for increased MIMO support and CA in devices is real estate. We all will need to carry the Note to fit it all. Or a Tablet.

Given all the brothels, it would be very fitting for Pahrump!!! Robert

We have converted you! Welcome to the Club. You are now a certified Wireless Dork!!! Robert

Most likely those sites have been accepted by Sprint from the OEM's and now are being blocked. You need to become a S4GRU Sponsor to access the Sponsor sections of our site. For more information about becoming a Sponsor, you can read this thread: http://s4gru.com/index.php?/topic/1195-information-about-s4gru-sponsorship-levels-and-how-to-become-a-sponsor/ Robert

It looks like they are starting a little behind schedule. Activity should start before the end of the month, though. Robert

In all seriousness, here is a comprehensive understanding of eHRPD: For the most part, eHRPD is EVDO-A. Both are 3G CDMA technology. EVDO is a High Rate Packet Data technology, and eHRPD is Evolved High Rate Packet Data. It is essentially the same exact technology, except eHRPD data is routed through the LTE core instead of the MSC (switch) so it can maintain the same IP address as LTE. This allows for data hand offs between LTE and 3G. Only LTE devices are capable of eHRPD connections. eHRPD and EVDO-A are broadcast from the same tower on the same channel using the same technology and the same backhaul. It is one signal, not two different signals. However, if your device is in CDMA only mode (or you have a non-LTE device), your data from your device goes from the site through backhaul to a Sprint MSC switching center is processed and dumped out onto the internet backbone. If your device is in CDMA/LTE mode and your site has been upgraded to eHRPD, when your device data gets to the site, it goes through the backhaul to a 4G LTE core instead of the MSC. There it is processed and dumped out onto the internet backbone. So, the only difference in performance between eHRPD and EVDO-A on the same site occurs at the MSC vs. the LTE core. Everything else is pretty much identical between the two. Each site in the Sprint network is tied to a very specific MSC for 1x voice and EVDO data. Sprint has dozens of MSC's scattered around the country. When that MSC experiences problems or has a logjam, it affects all the sites connected to it. And EVDO can slow down (although this is not the big culprit in Sprint 3G deterioration). In contrast to how the MSC's handle 1x and 3G EVDO data, 3G eHRPD and 4G LTE data are processed through 4G cores. Unlike MSC, sites are not limited to only one core. Sprint is setting up their 4G LTE cores to be dynamic. So if one core is too busy, data can be routed to a different under burdened core. Performance between EVDO-A and eHRPD should be very similar when on the same channel from the same exact site. The most common difference is that eHRPD will often have faster ping times. And a MSC is more likely to bottleneck than an LTE core, so at peak times EVDO may be slightly slower than eHRPD (when all things are the same).

Robert

Now that is odd. I have yet to find any of the apps that I use that performed any different on eHRPD. I have no answer for that. Robert

Because WiMax is a full deployment in your area and the nearest WiMax site to you is much closer than the nearest LTE site is now. As the deployment completes in Atlanta, you will find LTE coverage to be far superior to WiMax. Robert

Sounds dirty when you say it! Robert
