Without the actual procedure for the tests, it is difficult to say if PCWorld'ss are any good. I am not familiar with the software used as no major industry provider uses it. The standard tool in the industry is Windcatcher
It really depends on the way the test is run. The problem actually relates to the TcpWindowSize as it should be increased to at least 128Kb for HSPA based networks and for CDMA as well.
Another major issue is that Data Cards don't inherently support streaming. Streaming is often used as a secondary PDP context and this will have a major negative effect. Were they in a handover region or not? On HSPA, every other cell is an interferer so throughput should be measured with a Single Carrier in the active set. It is still possible to be in a handover zone while in a parked car.
Did they use the carrier supplied good coverage locations? Randomly may not cross the panaroma of RSSI.
As well, the latest modem from Novatel Wireless is the USB760. I also believe the latest Sierra Wireless card is the compass something or other. Did they use a Y Cable? Did they use an external antenna? What model of PC did they use as TRP/TIS makes a huge difference in low coverage areas?
Without more data, I would still say there isn't sufficient evidence to form any conclusions from their article.
Working in the industry, I can tell you phones have a really really short design period.
Typically the design starts around 9 months before commercial availability.
If the Iphone had fizzled, all Smart phone projects would have been killed.
We actually have caught up to Japan for the most part. There are other technologies at play depending on the region in the east (CDMA, WiBro, WiMAX), but WiMax is dying
If I'm not very much mistaken, Apple developed the iphone. There isn't a competition between at&t and samsung. It is a competition between phone manufacturers. And even that is not very a good competition actually because nokia has continued to produce 50 versions of the 2 crappy phones a year, SE is nowhere, samsung is trying something as is LG (both have shitty mobile OS).
There is a competition between AT&T and Verizon,Sprint, T-Mobile, etc all; and handsets are one of the areas of competition.
The IPhone has some rather significant problems as well. Because the feature set is somewhat limited, the duct tape and bailing wire used to keep the Iphone functioning is not as obviouis
If iphone were available to all cellphone users, then probably all cell providers would improve their networks.
Some operators already spend a bundle on their network. If you have been with Verizon Wireless for sometime, you can remember the bad old days of Airtouch. In 2002, There was no coverage in significant portions of west Nebraska along I-80. In 2003, You were pretty much covered all the way into Cheyenne. I remember when AT&T/Cingular froze capital spending. AT&T has one of the slowest 3G networks in the world.
Of course it is. Exclusive (in this sense) is just another word for lock-in and lock-in is bad by definition. Can you imagine how would it be if all had to buy computers from internet providers? You would be paying 10 times more for 10 times lesser hardware, and I hope you would like your monthly payments, and probably you won't even own the computer.
The true fact is that we are loosing ownership rights faster than you can imagine. Do you run MS Windows? You license software and no longer own it. In fact, you can never even own your own home in most states because of property taxes. Ownership is an illusion.
Since when? Even if there isn't enough of spectrum (which isn't true) some regulation would help to break down those lock-ins and other anti-consumer policies which would help with at least some competition. The problem we have now that there isn't a competition at all.
Spectrum is licensed by the FCC and sold at a very tidy profit. How many small operators are going to be able to afford the 1 billion dollar upfront cost? The FCC also changed the rules allowing some operators to obtain upto 65 Mhz in one market.
The real lack of competition comes in the backhaul. T-Mobile has to buy their backhaul from either Verizon or AT&T.
There is competition amongst the operators to develop the best handsets.. Without the iphone, would we have seen the Storm, Omnia or others?
Each device has it's good and bad points. The fact is that Cellular companies are only in charge of part of their network at best, and the and the handset shouldn't really be the determining factor of choosing an Provider At&T readily admits their network wasn't optimal for the number of users with the Iphone and they are now trying to remedy that so each user has a better experience. Only time will give a better indication
Exclusive handsets aren't necessarily a bad thing. It is just one factor that should be measured..
There really isn't enough spectrum to have true competition. The cost of the RF spectrum and cell site acquisition are the major factors for an operator.
I can only speak for the HSPA technology on DataCard. VOIP support will be a major feature in the next generation of cards which will be out later this year or first part of next year.
VOIP requires certain functionality called continuous packet connectivity which is introduced in a later version of the standards. In fact, there will be no circuit switch support on these data cards.

The overall application layer throughput is heavily dependent on a number of factors. The overall 3G Network is limited to 3.1 Mbps.
Does Clearwire have Mobility enabled yet?
The MiFi is a fully functional 3G (EVDO) modem with a few additional features. There is an HSPA cousin as well.
I am not actually an RF engineer so my thoughts/explanation may be completely ludicrous(it would not be the first time). My expertise is basically layer 3 through 5 of the OSI model
During the system test phase, a large number of measurements were performed to isolate the impact of Wifi Noise on 3G and 3G Noise on WiFi. It was found that there was actually minimal impact of Wifi on 3G and vice versa.
One Advantage of the MiFi unit is that the performance is better than that of a standard datacard. Laptop Noise is an issue with usb sticks especially in low coverage areas.

The problem is network dimensioning and issues of the backhaul connection between the NodeB and the RNC.
There are multiple configuration of the NodeB which provides for different Data Rates.
There is 384 kbs, 1.8 mbps, 3.6 mbps and 7.2 mbps.
AT&T was not interested in 7.2 Mbps until late 2007.
In order to support these data rates, there must be a significant connection to the backhaul based for the most part on a number of T1 Lines.
AT&T is attempting to dimension their networks based on current data usage so they will always be behind. This is due to cost and many other reasons. There is no reason to equip Nut New Mexico with a 7.2 Mb capable cells.
Even on the device side, It is cheaper toi buy a device based on HSDPA only rather than HSUPA/HSDPA.
1.) If the action your boss is requesting is illegal, inform the proper authorities.
2.) Abuse is a matter of perspective: Is your boss asking you to shape everyone to 64k as a maximum? Our legal system is fucked up. A line could be sold with a 7 Mb maximum, 768 kb average. Said line would only become abuse when it avaergaes 7kb on purpose.
3.) The only reqard for having morals must come from within yourself. If you are looking for anyone to recognize that you have morals, be prepared to be disappointed
Ultimately, you are in charge of your own decision. I happen to agree here with many who say to convince your boss for the alternate solution first.
Unless the request specifically borders on Fraud, your morals are safe and sound.

The need for the y cable is dependent on the chipset. Other advantages to the mifi is that no driver installation is required.
You are allowed to change the channel in the web ui.
Some cards require the use of
2 usb ports due to current requirements so you need a y cable.

Almost all the Acceptable User Policies contain explicit language about abusive users.
The only choice he has is to stay employed or choose other employment.
Owing users only comes at a certain point in time, The 5 Gb limit on wireless Data Cards is much more egregious.
This is absolutely the worst advice.
Like all Employees, you are required to abide by the requests of Managers/Supervisors unless such request is a crime.
The boss is simply implementing something that is common at this point in time.
Until your boss advises you to do something stupid and illegal, keep toeing the line or find ANOTHER GROUP TO WORK FOR.
