Verizon Wireless and the LTE Network…

Sunday, February 27th, 2011

I realize that we’re all human, however for technology services I tend to offer service providers with a pretty high level of scrutiny.  Over the past few months I have been trying out the Verizon LTE offering. For those of you not familiar with LTE it stands for Long Term Evolution. It’s a technology similar to GSM which is used world wide for cellular communications technology. Verizon Wireless recently has been upgrading and augmenting their network to add in LTE on top of its CDMA or Code Division Multiplex Access (what Sprint also uses as their core 3G service provider).

Nevertheless, last December a few days after the LTE network in Northern Virginia went live I went to my local Verizon Wireless store and bought a PanTech UML290 device outright. As an early adopter I realized that it potentially could be a bumpy road of sorts. Little did I know though that it would be a bumpy road of continual disconnects and frustration.

In January 2011 I called the Verizon Wireless help desk (note I’d called them in December as well) to discuss the issue I was seeing to ascertain as to whether it was just my modem sporadically having issues, or if it was more an enterprise issue.  While the technician did not admit to it being an enterprise wide issue, he did say that it seemed that a node I was connecting to at the nearby cell tower which was providing service was having a problem. Therefore, whenever I attempted to use the modem and it selected said node, an “at cause” event would occur.

This event would not disconnect the modem, but rather would cause it to essentially have the traffic shaped to it become negligible. In other words, I could ping other sites using ICMP, or I could perform DNS lookups, but anything that required communicating and retrieving web based resources where data packets were transferred was effectively zero. Pretty cool technology right?

So I was told that a ticket would be opened and that I would receive a ticket number that was associated with this incident. Once the ticket was opened the network engineers that work on Verizon’s network would investigate the node, physically checking the tower and replacing the component that was broken.

I have yet to receive that ticket number over a month later. Further, this issue is not isolated to just the tower near my residence but seems to be prevalent throughout the Northern Virginia area.

I’m not quite certain what Verizon is doing to correct these issues, whether it’s a software issue with the VZAccess Manager or an actual networking issues, but three months later and it’s still not allowing for connectivity greater than ten minutes (there have been some sessions that have actually lasted longer, but they’re few and far between).

Perhaps someone from Verizon Wireless will actually read this, perhaps it is just words entered on the Internet that will be disregarded.

If you’re thinking of using Verizon Wireless for it’s LTE network with lightning fast speeds, be wary that you may also be in for a bumpy road. While it’s incredible fast, it is unstable.

Maybe Verizon Wireless was lacking the funds to complete the network and figured that suckers like me would be their “investment funding” in the sense that we could get on the network but would be disconnected shortly there after and using our service fees they can use it as a cost recovery of sorts as well as a stabilization fund to fix the problems.  Seems unacceptable to me.

PanTech UML 290 LTE–First Thoughts

Monday, January 3rd, 2011

So I bit the bullet and bought the PanTech UML 290 from Verizon Wireless, flat out. Works like a champ… when it works. The above speed test was taken from my house.  I noticed that after about ten minutes, the card would stop transmitting traffic.  At first I thought, “alright, maybe there’s a hardware issue.”

Oddly enough though I would run an NSLookup and get a valid response. I would try to ping Google.com and it would ping. So I was left scratching my head wondering why I wasn’t able to transmit and receive anything other than just a DNS record or an ICMP. So what did I do? I called Verizon’s tech support.

uml290So I disconnected and then reconnected and all was back to normal with super fast network connectivity that scared me (yes, scared me thinking to myself that just a few years ago these speeds in a wired environment were usually only in corporate data networks or academic environments).  Then about ten to fifteen minutes later, boom, disconnect.  Third times a charm I figured, and gave it another reconnect request, this time the session was flawless and had no issues, lasted 45 minutes long and then I disconnected manually and left for dinner with a few friends.  When I got back, I opened a ticket with Verizon support – they called back pretty quickly and left a message since I wasn’t available.  Rather than shy away from the issue I went ahead and gave them a call to further discuss.

After talking with a gent about what was going on, it was confirmed from my network traffic that there were “at cause” issues where the modem would attempt to talk to a specific node of the LTE cell and be disconnected from transmitting at that level and cease data traffic altogether. Because it’s the network side an official ticket was opened and network engineering team will investigate the network hardware and routing to correct the issue.

So first thoughts, LTE is blazing fast.  LTE is expensive in that Verizon wireless is capping at 5 GB for $50, 10 GB for $80.  I’d like to see VZW man up and do what MetroPCS is doing with unlimited usage for $60

Nevertheless, according to VZW, they should have the issue resolved in 5 to 7 business days, I’m interested to see it get fixed and will report back then.

Bye Bye Goog-411

Thursday, November 11th, 2010

I’m a little saddened to read that Google is discontinuing their 411 service, however I figure that now that they the US population has freely provided millions of voices with different inflections, pronunciations and words, Google’s digital stomach is churning with information to dissect.

Nevertheless, with the capability ceasing and with smartphones a flurry, there are still ways to do voice searches on your phone without having to even make a phone call – though you will incur data charges should they apply… Checkout Google’s offerings yonder at http://www.google.com/goog411/index.html for more information.  I loaded the Google Mobile App on my iPhone last night and have to say that it’s come a long way since version 1.0. If only it was as easy as just voice dialing a phone number though so as to not be distracted…

Are we getting cooked by Wifi?

Sunday, January 10th, 2010

So over the past few weeks I’ve been taking more time for me. Not a bad thing right? Getting a balance back in place of sorts. One of my guilty pleasures is to read. Whether news feeds or books, it’s a guilty pleasure. Go ahead and book’em Dan-o (pun intended).
One of these news feeds is that of Gizmodo which showcases, you guessed it, gadgets and gizmos :-) Recently an article caught my eye dealing with a device to charge USB devices using Wifi signals. The charging device is made by RCA, more can be read here.

The question of course that this poses to me is whether or not this is a warning sign for those of us that live in neighborhoods that have several wireless running, colliding and interfering with one another. Are we getting cooked or is the power contained within the 802.11 spectrum harmless to humans because the wavelengths do not interact with the genetic and cellular makeup of the human body. Just sayin…

Nuance Dragon for iPhone

Tuesday, December 8th, 2009

Like whoa, Nuance has created an iPhone App and released it to allow for dictation similar to their Dragon Naturally Speaking software for the PC. Pretty wild but you can text or email, update a Facebook status, send notes and reminders to yourself, or tweet to the world… all using your voice and dictation.

It’s available in the App store, more information available at:

Watchmen & Wall-E Mashup

Sunday, April 12th, 2009

So I haven’t seen either of these films, but have seen the trailers for both and then came across this and thought that I felt I had to share it with you all…

Charting it up… The story of my life…

Monday, December 29th, 2008

If you’re a vigilant reader of XKCD.com, then you more than likely already saw this, but it cracks me up to no end…

'There's also a spike on the Fourier transform at the one-month mark where --' 'You want to stop talking right now.'

For those of you that like to graph everything, if you’re in the SharePoint or asp.net world, I’d recommend Dundas Chart. If you’re into utilizing web based APIs, Google Charts is pretty cool.

Please note that the “Point” that our friendly XKCD author is speaking of is not the use of SharePoint, though I’m sure that SharePoint has also had it’s mix of throwing monkey wrenches in relationships :)

No honey, we’re not going to use the BCD to solve this problem, I’ll write the data connection manually using custom code that doesn’t match any other schema we have…

Driving Simulator on Google Maps

Sunday, June 29th, 2008

So I came across this site this afternoon and just started laughing – it’s basically like Grand Theft Auto the original, completely 2D, but what’s that, I can drive over buildings?  Oh yes.

So, the one thing that I can definitely say that I found out was that it’s amazing how hard it is to control an 18-wheeler at 200 km/h.  Yes, that’s right, you have four different automobile options to choose from :)

Check it out :)

MacBook Pro or no…

Sunday, June 22nd, 2008

So I’ve been contemplating buying a MacBook Pro for a while now.  And yes, I realize that there will be a hardware refresh sometime in the next six to eight months… though I also realize that in the past whenever Apple has done a hardware refresh that there are typically some small problems (warping of cases, etc.) during said releases which means that the current MacBook Pro which is nimble and quick is at the height of its refinement.

What to do… Thoughts? Recommendations?  I know, go read a forum and make my own decision, but those are coming from folks that I don’t know :)

I Will Derive

Sunday, May 25th, 2008

So I would like to interrupt this analysis of the Four Hour Work Week (gone horribly wrong in my own lifestyle implementation recently) with a little geek humour – from our friends at /. that decided to post “I will Derive.”  It may seem somewhat trivial an exam, but I remember my days as a physics undergrad under the pressure of performing and having similar tunes in my head.  Nevertheless, enjoy…
