Vzaccess Manager Pantech Uml290 Driver CD With

As of this writing, all the cards use 7.6.3 on Windows. However, on OS X, the USB551L uses 7.2.3 instead of the newer and more stable 7.2.5 that the older VL600 and UML290 datacards use.

Both modems use Verizons VZAccess Manager program on OS X and Windows.

I guess that brings me to my primary complaint about both of these data cardsthey dont have internal storage partitions with the software stored on them.

The obvious reason for this was that you could then have a guaranteed way of getting online even if you didnt have the driver CD with you.

Without this, you can potentially be stuck in a maddening Catch-22 situation where you could conceivably get online, but only if you had the foresight to install drivers beforehand.

I literally have a small pile of various modems for EVDO and UMTS that all have this simple feature.

I sincerely hope newer modems have the feature, and that the reason this is lacking is purely due to the current architecture of these cards and not some legal preclusion.

The UML290 needed a firmware flash from the Windows version of the VZAccess Manager; then I could download the OS X version of VZAccess Manager and use the UML290 without issue.

However, I spent equal amounts of time just testing the two on a 2010 MacBook Pro and 2011 MacBook Pro.

There are tabs for both connectivity management, statistics, SMStext messaging, and finally WiFi locations.

At the bottom is a persistent bar displaying connectivity status, duration, activity, current cellular number (the data card still has a phone number for SMS), and signal strength.

Hovering over the signal strength bars creates a bubble with more details about the current cell environment.

When connected to 1x or EVDO, you get the current RSSI (Received Signal Strength Indication) for both 1x and EVDO.

When connected to 4G LTE, you get both RSSI and SINR (Signal to Interference Noise Ratio).

This can come from reflections that exceed the cyclic prefix length, and more importantly from doppler shift, which causes loss of carrier orthogonality when the user equipment is moving quickly.

Based on the definition of SINR and the data I collected, it seems that theres either a missing negative sign, they report the inverse, or something else is wrong.

Higher SINR is better and should result in better throughput.

This is somewhat of a problem because it can force you to drop back to EVDO while the SMS is received.

I disabled this in the client and never experienced any problems.

On Windows, you can also send AT commands by hitting control-T, which is pretty much what you have to do to reconfigure proper APNs if you used the UML290 on OS X before the official firmware flash and update went out.

There are fields for average and maximum over the sampling window down below, and running totals for the current data session.

This is fixed in the newer version and is much smoother, reflecting the actual throughput profile.

This can take a while sometimes unless you always use the same datacard.

Ive put together a full gallery with screenshots from the Windows and OS X versions of the access manager suite.

Theres a majority of stuff which is virtually identical between the two versions.

As of this writing, all the cards use 7.6.3 on Windows.

However, on OS X, the USB551L uses 7.2.3 instead of the newer and more stable 7.2.5 that the older VL600 and UML290 datacards use.
