| Unfortunately, Verizon won't miss the loss sales. They have made a coporate decision - and will no longer look over sales (up or down). Whoever suggested this approach - will make darn sure it isn't revisited - period. Hopefully the 3GStore won't have a great loss by not marketing Verizon AirCards. I would imagine the profit margin is much greater for "hardware" sales (hopefully). |

That may not be entirely true. This may not have been a "corporate decision", but rather an isolated/regional decision by someone without much knowledge on the topic.
We are trying to bring some exposure, so that people at Verizon (hint: legal department) will realize how stupid this is and quickly fix it. _________________ EVDO :: EVDO News :: EVDO Antennas :: Buy Verizon :: Buy Sprint :: EVDO Amplifier |

I thought my reasons for seeing validity were supportred in my posting itself. In case not, the argument was essentially economic/business.
My credentials really shouldn't matter, though if you really want them I think you can find them with a little Google searching under my amateur radio call sign which is -

Oh my - n6gn holds a FCC Extra Class License which is the top of the ladder in Amateur Radio. I also hold an Extra and agree completely with n6gn.
FYI - here is a breakdown necessary to reach the Extra Class License...
Novice Class License. Persons who had passed a 5 word per minute (wpm) Morse code examination and a basic theory exam.
Technician Class License. You can get an entry level Amateur Radio Technician license by passing a 35-question multiple-choice examination. No Morse code test is required. The exam covers basic regulations, operating practices, and electronics theory, with a focus on VHF and UHF applications.
Technician Class operators are authorized to use all amateur VHF and UHF frequencies (all frequencies above 50 MHz). Technicians also may operate on the 80, 40, and 15 meter HF bands using Morse code, and on the 10 meter band using Morse code, voice, and digital modes. No Morse code test is required.
General Class License. The General Class license offers a giant step up in operating privileges. The high-power HF privileges granted to General licensees allow for cross-country and worldwide communication.
Technicians may upgrade to General by passing a 35-question multiple-choice examination. The written exam covers intermediate regulations, operating practices, and electronics theory, with a focus on HF applications. You must successfully pass the Technician exam to be eligible to sit for the General class exam. No Morse code test is required.
In addition to the Technician privileges, General Class operators are authorized to operate on any frequency in the 160, 30, 17, 12, and 10 meter bands. They may also use significant segments of the 80, 40, 20, and 15 meter bands.
Advanced Class License. Advanced class operators have passed the Advanced written exam, in addition to the old requirements for General (Novice, Technician, and General written exams, and a 13 wpm code test). Advanced class operators have additional HF operating privileges beyond those of Generals.
Amateur Extra Class License. The HF bands can be awfully crowded, particularly at the top of the solar cycle. Once you earn HF privileges, you may quickly yearn for more room. The Extra Class license is the answer. Extra Class licensees are authorized to operate on all frequencies allocated to the Amateur Service.
General licensees may upgrade to Extra Class by passing a 50-question multiple-choice examination. No Morse code test is required. In addition to some of the more obscure regulations, the test covers specialized operating practices, advanced electronics theory, and radio equipment design. |

The only thing I can say is that the little time I had Verizon, the 3G store's customers service, support, and working knowledge of the VZW network was far superior to Verizon itself.
VZW should have taken the 3g store as an example of how to run a business. |

For that matter, when that happens, it's not just VZW but the network hardware of every carrier within range that sees the effects. Thus the economic impact seen by 3Gstore is a great deal less than that seen by the carriers who have already invested billions for spectrum.
I'm also not defending VZW or other carriers for taking customer's money while implying something [ 3G coverage & capacity] that they don't have and can't provide. And I'm not defending their implicit actions which favor close-in customers who use only small amounts of data to more rural ones who have no other acceptable 3G-like access to the Internet; after they advertise in a sort of all-customers-are-equal way. But I do see that 100*$69/month (all users within range of errant amplifier) is a bigger number than $69/month for the one user causing a problem to a network of cell sites each costing $250,000. And this is without adding on the $K required to go hunt down the offending amplifer/installation and solve the problem.
The reality is, as I've pointed out in other threads on this forum, that none of the carriers has sufficient network to simultaneously provide both the 3G capacity and coverage that they imply in their advertisements. "There's a map for that" is an excellent example of this in that it purports to show 3G coverage but hides the nasty detail that with EVDO that 'coverage' is really only one user per cell/segment (carrier). As EVDO users on this forum know, once a single carrier starts getting loaded (busy with other users) even with unlimited backhaul capacity, everyone using that RF carrier (channel & sector antenna) notices the slowdown and performance degradation.
In some respects, non-CDMA systems are more up-front about the projected or expected 'user experience'. They also have their limits but these limits are hard rather than soft as is CDMA so the users get a "system busy" or similar message when capacity is exceeded rather than just lousy performance.
Any way you look at it, the Last Mile Problem is real and leads to geographic favoritism.

n6gn wrote an eloquent viewpoint summary, concluding with:
"Any way you look at it, the Last Mile Problem is real and leads to geographic favoritism. "
I would rephrase that: the Last Mile Problem is real and 3Gstore products are the solution.
From the information presented on this forum I believe the issue is not oscillating amplifiers or overloaded cells or bandwidth constraints. The issue appears to be market share for a new product, Verizon's femtocell. Verizon is playing dirty.
If the "Verizon Wireless Network Extender" (femtocell) gave good value, Verizon would allow their product to compete fairly in the open market. |

I don't even see how the "femtocell" would compete - unless it had one of the huge antennas and/or boosters. EVDO at the edge tends to be customized so I doubt they would have that (some need a Yagi, some just need a big antenna, some need power boost, sometimes the antenna just needs a window, sometimes a roof).
How is the femtocell going to get a signal to run at the full speed?
And I'm not going to buy a femtocell when all I need would be an antenna and/or booster and those would likely work better! |

Seems to me that Verizon's "femtocell" versus the products 3GStore sells is a totally apples-to-oranges comparison. They are really not in the same market at all. To use the femtocell, you must already have a solid, fast internet connection. If you have that, you probably live in an urban area that also has a good cell signal as well, at least outside your house. The femtocell just provides another way to help you get a cell signal inside a building.
The products 3GStore sells are for those of us who have NEITHER. My sole phone service AND internet service is Verizon Wireless (no other company's towers are nearby, and the quality of AT&T's phone lines around here are so appalling I canceled that service outright). But I had to put an antenna up on a 30-foot mast to get line-of-sight to the Verizon tower.
Without antennas and a booster I would have NOTHING. Even starving people in Bangladesh have better service than this area, in the supposedly-first-world USA. |

There may be more than a single way but an easy way to use an amplifier incorrectly is to not provide enough isolation between the input and outputs.
FOr an in-line amplifier it might be tempting to think that because there aren't two antennas, an 'indoor' one for the handset side and an 'outdoor' one better positioned to get to the cell site, there's no way that insufficient isolation should occur. However, at least for several revisions of one of the dual-band Wilson's there was significant coupling *within the amplifier package* which caused poor performance. This could be exacerbated by varying the impedance match provided by the antenna(s).
In the extreme, amplifiers with insufficient isolation will oscillate, generally somewhere within their operating range and often at or near full power. Amazingly, they may continue to limp along and 'work' for the user under these conditions. While manufacturers seem to make a big deal about how they 'computer control' their devices, I have found the actuality to be less than satisfactory - at least in the case of one Wilson model.
Another way an amplifier may be mis-applied is by applying too much power at the ports. Power control algorithms and hardware in the handsets do have some range and can adjust to a degree, but it's possible to select and use amplifiers having too much gain and without enough internal attenuation to keep the result from being a very distorted signal. Here again, it may be possible to maintain a connection but at the same time generate unwanted signals (distortion) and interference to other users in the cell and perhaps even on other carriers' networks in different cells. Non-in-line amplifiers that use antennas on both ports are particularly prone to misapplication since it is left to the user to locate the antennas in a way that provides sufficient isolation.
Unless you have good reason to believe that a handset or data card is not properly designed and operating properly, it is worth asking the question why would an amplifier located near the handset improve anything? If it did, why didn't the carrier/vendor put it there in the first place? There may be situations where the handset/card is separated from an external amplifier by a great deal of cable loss. In that situation it can make sense to use an in-line amplifier with gain approximately equal to the cable attenuation. However, simply applying a bi-di amplifier with the thought that it will make something a great deal better (for all) without considering the ramifications is, in my opinion, not a good idea.

n6gn’s good points taken; I think this is a pretty shortsighted decision by Verizon. These amps/antennas are available all over the place; from the web down to your local Radio Shack. Preventing a reseller of Verizon form also selling amps/antennas is really going to have little or no effect on how often they are used. Do they think that users of this forum would not continue to point fellow users to use them, be they sold here or on another site? It seems to me all this move does is cut off a reseller channel (potentially costing some sales) without significantly addressing the ‘problem’ (if you subscribe to the belief that amps/antennas are a problem).
My own experience with the 3G store and Verizon went like this. I heard about EVDO, and hit the web to learn more. I found this site, loved the information and community, and bought my first EVDO modem here, as well as the Verizon service. After receiving the product and using it for a couple months with limited effectiveness, I later purchased an antenna, and later an amp, but both from another site (3GStore didn’t carry much in that line at the time). After adding the amp, I finally had a stable connection.
The bottom line is the 3GStore made me a Verizon customer. I purchased an antenna and amp due to necessity, and would have done so if they were sold here or not. I’m sure this is true for many many other customers. To me, Verizon is making a poorly thought out decision; or they have other undisclosed reasons for not wanting 3GStore as a reseller, and are using antennas/amps as a convenient excuse.
The 3GStore has been a long time proponent of EVDO, and how to make it work well. This can be nothing but a benefit to Verizon, and a free one at that. Strange they would not see it that way. |

If that is truly the case and this was not meant to be "home broadband" how come when I go to verizons site and check for DSL or Fios qualifications they tell me that they are not available but I can sign up for Verizon Wireless Broadband.
That in itself implies that I can use this for my "home broadband" connection. |
What part of "Mobile " Broadband don't you understand?
 |
I didn't start this topic, but yes I do understand what the word mobile means. There is really no need for such a nasty attitude.
My "mobile" broadband is also my main, yes you read that right, my one and only, source of broadband connection for my home,and I make no appologies for that fact. If I could get traditional broadband, and even as happy as I am with the speeds of 3G service, believe me. I would get the traditional broadband. the data cap is better and the price most often much lower, but as 3G service is all that is available in my area, I don't even count the so-called satellite internet because of the vast cost and the dial up like connection speeds of my poor neighbors, then 3G is what I use, and will continue to use as a primary service until I am offered a better option.
Without an antenna,I'd never get a decent signal. Verizon, IMHO, just wants to be able to push people into buyng same or similar products directly from them. And, we all know how much those products can be overpriced when you purchase directly through Verizon, itself.
Verizon really has shot themselves in the foot here, IMHO!
