Are you mocking the legacy network? AJ

Go back and read the data portion of the Ts and Cs that I cited or even just the phrase that I quoted. What do you not understand about "or other equipment for the purpose of transmitting wireless data over the network" and how that applies to a connected TV? AJ

Josh, Leap has already been through one bankruptcy, so it is watching every penny. And, honestly, it may have trouble meeting its financial obligation to Sprint. I believe that you can personally relate to that, yes? AJ

No, be careful with that prediction. LTE 800 may provide broader coverage than EV-DO 1900 does, but there is no guarantee. And "significant margin" is probably too strong. AJ

It may or may not be, just as tethering may or may not drive more data traffic. But in both cases, the potential for abuse is high. In this case, watching video on an HDTV tends to be more palatable than watching video on a 4.7 inch screen. So, people tend to do it more often and do it for longer periods. In any case, streaming video over the macro network from a handset to a TV almost certainly violates the Ts and Cs, since it is "an activity that connects any device to Personal Computers (including without limitation, laptops), or other equipment for the purpose of transmitting wireless data over the network." I am getting really sick and tired of many of you people. More and more, I am not sure why I bother to provide my dozen years of wireless research experience to this forum to help you understand Network Vision. Sprint is doing a complete network renovation, but many of you yahoos are going to drag down Network Vision in just a few years with your "unlimited" data usage because you cannot exercise a small amount of self control and common courtesy to the subs around you. The sooner that Sprint encourages or even forces people to monitor their data usage on the macro network, the better. AJ

It is a continuous, high data rate activity that sucks up capacity from the macro network, and that detrimentally affects the ability of truly mobile users to use the macro network. After all, these are mobile devices, folks, not "sit at home and use the macro network when you should offload to Wi-Fi" devices. AJ

Regardless, there is really no reason to be using the network to stream video from a handset to a TV at home. That is bush league. Instead, that is a classic Wi-Fi offloading activity. AJ

Actually, you could be violating the Ts and Cs if you are streaming video too often, using too much data, and/or affecting others' ability to use the network. AJ

Actually, with unity frequency reuse, which both CDMA2000 and LTE employ, adjacent sectors/sites always overlap with each other, hence interfere with one another to some degree. That is simply a fact of life. You can see this in action if you observe CDMA2000 PN offsets or LTE serving cell IDs as you circumnavigate a site. The PN offset and/or serving cell ID will not flip immediately with each sector transition. Essentially eliminating interference between adjacent sectors/sites would require one of two unpalatable options: Unity frequency reuse would have to go away -- a different carrier would have to be deployed on every adjacent sector. But that would reduce overall capacity dramatically and make larger bandwidth LTE deployment impossible. Alternatively, adjacent sectors/sites could have beam widths, downtilt, and power adjusted so that they never overlapped. But that would create three bladed hotspots of coverage with gaps in between sectors and sites. So, in a single frequency network, overlap/interference is a dance of compromise. Fortunately, Sprint was built from the ground up as a single frequency network, so network planning took these concerns into account from the beginning. T-Mobile, on the other hand, faces some challenges, as it tries to operate a network reconciling the frequency reuse of GSM with the unity frequency reuse of W-CDMA and LTE. I would not be surprised if T-Mobile GSM really goes in the tank in the process. Yes, the three sector panels are physically separated, but at typical distances from the site, those three panels are effectively a point source. AJ

That depends on how you look at it. Beam width is usually specified as degrees of arc at the half power points. In other words, if it is a 65 degree panel, then the power response is -3 dB at ±32.5 degrees. But the polar response does not stop on a dime. If it did, a three sector site with 65 degree panels would produce coverage that looked a lot like a three bladed propeller -- big coverage gaps in between sectors. So, no, even though the power response is -3 dB at ±32.5 degrees, the polar response continues out to ±60 degrees and beyond to cover the entire 120 degree sector. AJ

As I indicated above, you measure beam width in degrees. Take a sheet of paper and draw a large letter "V" on it. Take a protractor, and measure the angle close to the vertex and near the ends of the stems. Sure, the arc or chord length will be greater towards the end of the stems, but the angle measure will be the same. AJ

No, 120 degrees is essentially correct. Divide 360 degrees by three, and you get 120 degrees. And the overlap between sectors would be effectively the same regardless of distance because the beam width (in degrees) is constant. AJ

The cool thing about ZTE handsets is that they come with Baidu as the default search engine. Oh, and the Chinese government archives all of your phone calls, SMS, and e-mail for free. AJ

Nope, I have already seen in FCC filings how the naming scheme is going to play out. A newly created SoftBank subsidiary called Starburst II will acquire a majority interest in Sprint Nextel. Then, Starburst II will rename itself Sprint. The Nextel name is being completely excised. AJ

How dare you?! Pure Android loads applications fully 0.08 seconds faster, and that makes all the difference in the world to a phone geek...er, I mean..."power user." AJ

But that is exactly what VZW did with the "lightning" LTE commercials referenced in a post up the page. VZW marketed the future. When those commercial started running, how many VZW markets had live and accessible LTE? Any? Even now, roughly two years later, how many smaller VZW cities and rural areas are still without LTE? One interesting bit of data analysis that I gleaned from the top 50 market share numbers that we recently hosted is that only 40 percent of VZW's subs live in the top 50 markets. The other 60 percent, the majority live in smaller markets. Compare that to Sprint and T-Mobile, which have 55 percent and 60 percent, respectively, of their subs residing in the top 50 markets. The relevant takeaway from that is a lot of VZW subs in smaller markets, meaning a lot of VZW subs overall had to wait a while for LTE. Yet, that did not stop VZW from selling them the future. AJ

So, the rule of thumb should be do not pay by check with funds that you do not currently have. Instead, use a credit card and take advantage of the billing cycle and grace period. Or simply wait and pay the bill later, even if that means paying the bill late. AJ

I doubt that is going to happen. Samsung has cast its lot with AMOLED. As I wrote in another thread this morning, Samsung seems to be trying to take its entire smartphone production supply chain in house. Samsung already sources its AMOLED panels from itself. If Samsung were to switch back to LCD, it would likely have to source panels from LG and/or Sharp because, to my knowledge, Samsung makes only TN and PVA panels. And for smartphone LCD panels, anything short of IPS (or equivalent) is unacceptable these days. AJ

I have not seen any solid evidence that Exynos 5 will include baseband modem, WLAN/Bluetooth, and GNSS all on chip. Can you cite a source? Regardless, if true, the modem easily could be 3GPP only (LTE/W-CDMA/GSM), not 3GPP2 (CDMA1X/EV-DO). Even if it were to include 3GPP2 capability, it would be immediately suspect. Samsung handsets that have bypassed Qualcomm have had notably poor CDMA2000 performance. Like it or not, Qualcomm is the first and last word in CDMA2000 mobile chipsets. Samsung is trying too hard to be vertically integrated, paring its smartphone production supply chain down to few, if any outside suppliers. That may be good for the bottom line, but it is not good for consistent quality, as Samsung has to be a jack of all trades, master of none. AJ

Contrary to popular belief, a PRL update rarely changes very much and probably does not affect your home market at all. So, sure, a PRL update might lower in priority or even drop a certain roaming network in a given market. But those roaming sites were never in the equation unless a device was actually roaming. For example, when a Sprint device is on the native network, it has no idea if there are no VZW roaming sites in range or 100 sites. AJ

Nope, every native network site in the market is at the very same priority. Roaming coverage, however, is set at a lower priority. AJ

The EV-DO roaming in the South is far too widespread to be Cricket. It is VZW (former Alltel) EV-DO, part of a roaming pact that Sprint signed with Alltel prior to the acquisition and that VZW must honor. AJ

Network acquisition. The PRL instructs the device to search the appropriate channels. Assuming more than one network is found in the search, the PRL sets which network takes priority. AJ

Are you sure that you actually have had EV-DO roaming? That requires a special PRL. Most Sprint PRLs enable only CDMA1X roaming. Regardless, both EV-DO and CDMA1X, native or roaming, will display "3G." AJ
