SPOT Satellite Messenger Shared Page

June 24th, 2008

I’ve had a SPOT Satellite Messenger for about 6 months and really like it.  I use it primarily when I sail to keep my friends updated on where I am, and if I’m safe.

I have always been a little annoyed that the only ways they could keep track of my course were to save the individual SMS’es or emails that were sent, or I had to give them my password to my private online account at the SPOT home page.

Recently, the folks at SPOT came out with the SPOT Shared Page to solve this problem.  It’s still a little rough around the edges, but it’s far better than the previous solutions.  The page contains a list of the last 24 hours worth of messenger check-ins on the left, and a Google Maps layout of the track on the right.  You can click on the track to see more details.

Seems to be pretty reliable – does seem to be browser picky right now – Firefox doesn’t seem to work sometimes, and Safari doesn’t work at all.  There are some annoying formatting issues as well as images that are missing in some areas.   Hopefully they’ll spruce some of this up as more folks find it – it is in beta as far as I understand it.

Here’s an example:

EVDO update – Sprint vs Verizon

June 19th, 2008

I’ve had some time to play with the EVDO options out there – I ended up getting a Sprint card in addition to the Verizon one I had as well. The Sprint card is a Novatel Wireless EX720, and I have the usual 5GB monthly plan.

Both Verizon and Sprint have similar UI’s for their management applications.  I like Verizon’s statistics graphing capabilities, but I much prefer the Sprint application for everything else – it seems to be better adapted to deal with Windows Vista.

The actual service is far better on the Sprint network than Verizon.  Based on my testing thus far, here’s some comparisons:

Verizon

Latency: 138ms
Download: 756Kbps
Upload: 182Kbps

Sprint

Latency: 101ms
Download: 1094Kbps
Upload: 435Kbps

This is from the same location, the same night.  The Verizon towers seem to be pretty consistently slower than Sprint.  I’ll do some additional testing over the next week or two to see if things stay the same.  Thus far, I’m going to stay with Sprint.

Here are the speedtest.net results:

Wireless Broadband Woes

June 10th, 2008

So, with my new Dell laptop, there’s an option to have a WWAN, or wireless WAN card, also known as wireless broadband, EVDO, etc. I didn’t order the laptop with that option, and happened to be working on a work project with Verizon Wireless, and started chatting with their engineers about it.

EVDO Rev A sounded interesting enough to me to explore – 1-3Mbps of download, and 600-1200Kbps upload – as good or better than my old Clearwire service.

The first hurdle was ordering the add on card for the Dell. Since it is “embedded”, it was supposed to have been added at the time I ordered the laptop, and Dell support said I couldn’t add it after the fact.  After a little digging, I got the correct card, I believe, and installed it.

Then came activation – it was a nightmare.  I was on the phone to both Dell and Verizon who didn’t know what to do or who owned what part of the activation.  I eventually went to 3GStore.com and activated it through them.  They were extremely helpful, and the business day after I ordered, they had activated it for me.

Unfortunately, it didn’t work very well.  The software that comes with the Dell re-branded Novatel Wireless card is a Dell front end application, with Verizon’s VZAccess code being reused in the back end.  All of the advanced options are completely gone.

The first issue was that even though the card was activated, it still took 2-5 tries to get it to connect.  Various random errors about authentication service unavailable, wrong username or password, and a host of 900 series errors that most people familiar with this stuff will cringe when they see.  2 days wasted.

In addition, once the card actually connected, it only stayed on EVDO Rev A for about 30 seconds, then dropped to 1xRTT, which is, well, dirt slow.

After 4 hours on the phone with Verizon, and a couple with Dell, I was convinced that the card and software were flawed.  I don’t really care what it is – I’m a bit surprised but not overly annoyed.  In reading a lot about embedded EVDO, most of it fails in one way or another because of the finger-pointing of the manufacturer (in this case Dell) and the provider (Verizon).   Dell is only making money on the card itself, and installation, and Verizon makes their money on the plan and monthly costs.

So, I went off to the Verizon store and picked up a Kyocera KPC680 express card, and everything worked flawlessly – I’m actually writing this post directly from it.

Overall, the throughput and latency are manageable, and in most cases, completely acceptable.  To be able to be online from basically anywhere I frequent in the Seattle metro area is well worth it.  I’ll give it about 10 days to make sure there aren’t any major issues, and then cancel my home broadband connection.

FWIW, I’m getting about 600Kbps download / 250Kbps upload here at home, and I have only one bar.  If I move near a window, that goes much further up.

More info as I test it out…

XPS 1330 update

June 5th, 2008

Just thought I’d write a quick update on the new Dell XPS M1330 laptop.

The only two issues I’d report on the laptop thus far:

The “D” key seems to stick if I hit it a particular way.

On resume from suspend, the screen resolution drops to some abysmal level – 1024×768 instead of the default. Nothing I’ve done seems to fix it. I’ve searched in a lot of places online and haven’t found a resolution to the issue.

I’m working on getting my WWAN card activated because I want to try that service out and see if that is an acceptable replacement for my normal cable modem at home, which I don’t use that much. I’ll write more about that soon.
