Re: EVDO Questions...
I'm gonna recommend not buying a router yet just so you can test the USB adapter first with the external antenna to see if you can get service.
The best USB card right now is the Novatel U720. Go to 3gstore.com and click on the Novatel U720 on the left. Then you will see the KR1 router and antennas as well as an amp. I would try the external omni antenna and if you really want an amp get one but I think they're too expensive. I would just try it with the antennas first.
So now I would order the U720 through Millenicom and the Omni External antennas through 3gstore.com and get them setup right away to see if you can get service. |

Is the Novatel Ovation U720 the best EVDO USB card from Millenicom? Or is it the 595 thing?
What Do you recommend as an antenna? I need it to be EXTREMEly good at dissipating noise and improving signal. I think I'm gonna buy it from 3gstore.com. I'm going to buy the amp from 3gstore.com (The only one that they have)
THANKS EVERYONE |

The U720 and 595U are both very good USB adapters. The U720 is only $50 while the 595U is $100. The 595U also has a battery that has caused some problems because it will run dead in a low signal area such as your own and then you're screwed.
I would order the U720 through Millenicom and then order the $82 external omni from 3gstore or a yagi if you can find one. |

The 595U is not the preferred modem to use in "fringe" areas. It carries an onboard battery that has to work harder to push out the power to connect and stay connected, especially during high bandwidth usage in less than ideal coverage areas. After a while you'll see your battery begin to deplete and ultimely even die. Then it will be sitting there with a red light on continuously and possibly not putting out as much power as it should be and effecting your connection.
The U720 comes with a Y adaptor that allows you to plug it into 2 powered usb ports and doesnt need a battery. Less stuff to go wrong, does the same job.. = better product.

| Why would a USB modem need a battery anyways? If it's the save power on a laptop I don't see why, these modems transmit less power than a SOHO router, 17dBm max I believe.

| I dont think its necesarilly to save power. I just believe the configuration is different on a PCMCIA card and a USB card. I suppose the PCMCIA card allocates more pins for power giving the card the power it needs. The USB modems all supply a different power route that adds basically an another source of power aside from the single usb port. The U720 provides a Y adaptor that draws power from two powered usb hubs and funnels it into the U720. The 595U on the other hand, tries to be a little more slick in this by implementing an onboard battery that is charged from the usb hub while the connection is disconected/dormant.
Will the U720 work without the Y adaptor in place? YES, but its not able to power up to its full capabilities when connected that way. Just like the 595U will operate with the battery low/discharged, but again not at optimum levels.
The benefit of the U720 over the 595U is that you have no battery to worry about. However you do need a second USB port, which is not allways available. That is where the 595U has its potential, but you also need to consider your coverage on the 595U, battery expenditure is higher the weaker your signal is, and you can ultimately drain your battery with heavy use. You need to weigh the pro's and cons when deciding on a USB modem to determine whats best for you and your situation.

| Great answer, just what I've been looking for. I've been trying to decide on Sprint or Verizon, and whether to go with usb or express card. I'd like usb but have read about all the problems with the 595u. I want to be able to move the card to different computers, desktop and laptop, and will be traveling, so I'm bound to be in fringe areas at times. I'll have to look closer at the u720, and I'm leaning toward Sprint.
Thanks again. |

Ok, here's the real deal with the Y-connector. A single USB port is supposed to have a max of 500mA. The Novatel U720 averages around 400mA while in use. However, the max is 700mA. To get that extra 200mA, it needs to be connected to a USB port that doesn't share its power with the one already plugged in. Some computers will have a "hub" and 2-4 ports may share the same 500mA. If you really want to be sure it's receiving all the power it can, buy a USB hub with its own power supply.

| Just a note... it looks like the 595U is capable of using the most power. I'd guess the more power it uses, the stronger it broadcasts, but I'm not any radio expert.

| Last I checked, I think all the devices transmit the same power, about 17dBm I believe. If there's anything I've learned from evdo cards it's that the transmit power should not be a priority, just distance from tower and the geography of the area. Even with an amplifier, (maybe 500mw?) it's no substitute for distance off the ground.

| My PX500 transmits at a normal output of 7-10dBm according to the manual, with a max of 24dBm. The U720 is also 7-10dBm normal with a max of only 23dBm. It seems the U720 puts out a slightly nicer signal, though. The AC595 seems to lack reasonable documentation...
