Looking back on today’s communications outage

Mar 23

Posted by Ian Littman in Tech | 6 Comments

UPDATE 4: Added a Kerrville Daily Times link for a new article on how 911 is handled. Lots of good information there.

UPDATE 3: Added another news source. Swamped by homework so tweets will have to wait, but other than those I think I’ve got all the online info on the outage linked from here.

UPDATE 2: Added another couple of news sources, corrected one of my usual typos…some how I forgot to add a “not” into the paragraph about Wal-Mart taking credit card transactions. Sorry for the confusion. Also modified information based on an article from the Fredericksburg Standard Radio-Post. The link below takes you to the subscriber-only version of the article; the non-subscriber snippet just makes the paper look bad (very little info).

UPDATE: Added some more news articles, (still) working on collecting all tweets about the incident, revised some information for accuracy (originally wasn’t sure about CricKet and Pocket, but they too were taken down by the outage…DSL was also apparently iffy in Kerrville).

Granted, I wasn’t in the area when it happened, but since I have plenty of family and friends down there I’m certainly going to talk about it! Read the rest of this entry »

If the iPad can do this stuff, I’ll buy it

Jan 30

Posted by Ian Littman in General | 2 Comments

So the 3G version of the iPad (announced Wednesday) is still three months away, but I already have some expectations that, if met, would cause me to fork over $630 for the sucker…these expectations are realistic technology-wise, though I’m pretty sure they would require a jailbreak to get working…

1. SIP VoIP, over 3G and WiFi, with Bluetooth and in the background
I’ve successfully run phone calls over AT&T’s HSPA network, so assuming the processor on the iPad is “all that” this shouldn’t be difficult. If I can get a SIP client that connects to a Bluetooth headset and allows other applications “up front” without killing voice quality then I’ve got a very versatile system for nformation gathering while “on the phone.” This is particularly useful when you see my other requests below:

2. Full-fledged RDP, SSH and VNC clients…and either GoToMyPC or LogMeIn if at all possible
The iPad can be an excellent remote access tool; its screen has enough resolution to run any modern OS without having to scroll around. Add in the keyboard accessory and you’ve got a lovely little remote terminal that works anywhere AT&T has service (I’m talking about the 3G version here). Or any other non-AWS GSM or 3G carrier for that matter; the device is unlocked. SSH would be a godsend for doing command line heavy lifting, though you’d need a host to SSH to in this case (not a big deal for me). Even nicer, all of the above will likely be available for the iPad as App Store apps; no jailbreaking required.

3. A high-quality PDF viewer
I want a PDF viewer that can search and copy text, preferably at least as good as Preview. Yes, Preview can be outdone with PDFs…it’s not the most compatible piece of PDF reader in the world unfortunately. Read the rest of this entry »

My experience with GVTC

Dec 22

Posted by Ian Littman in General | 2 Comments

So I’m headed down to South Padre Island for some downtime with the family before Christmas. We made a pit stop at the Flagstop Café and my mom noticed that there was a big sign in the window advertising the availability of WiFi.

So naturally I pulled out my HTC Touch Pro, which has WiFi, to see what network they were running on. After registering for an account on the hotspot provider (Less Networks, never heard of them) I checked whatismyip.com to see who I was on. Sure enough, the connection there was GVTC, registered as “Guadalupe Valley Telephone”. Right before we pulled out of the place I opened up my laptop, logged into the WiFi network that way and did some tests. Read the rest of this entry »

Force 3G on a Sierra Wireless aircard on a Mac…here’s how

Oct 17

Posted by Ian Littman in General | 2 Comments

So I bought an AT&T data plan earlier today. SIM-only, no contract. Pretty cool, since their less-than-a-month-old 3G network around here is still pretty speedy. I didn’t need an aircard as I purchased a Sierra Wireless USBConnect 881 back during the days of “unlimited” GoPhone data for $20. The card lay dormant after “unlimited” became 100MB (big difference) but today it meant the difference between signing a contract (aka not getting service) and not signing one.

One problem arose when I got home: my aircard kept switching to EDGE during the middle of a data session. Not a good thing for a $60 + taxes and fees data plan. So I needed to force 3G on the card. The problem there was that only the Windows Sierra and AT&T clients allow forced 3G. So (not knowing that settings are stored on the modem and thus once I set 3G-only on my Windows computer it would be 3G-only on my Mac) I scrounged around and found this page. I followed those instructions and was able to make sure my aircard was 3G-only.

If you don’t want to read through a (relatively short) page on how to kick your aircard into high gear, you’re in luck. Here’s what you’d do on a Mac to force-3G a Sierra aircard. Note that this procedure was performed on OS X 10.6.1 and with the Apple “native” driver installed (a tiny download from here). This is also with the latest modem firmware, which I had to use the Sierra driver (vs. the native one) to upgrade to.

  1. Go to Terminal (Applications > Utilities)
  2. Type in screen /dev/tty.wwanCMD 115200 and hit enter.
  3. Type in AT!band? and hit enter.
  4. If you see the number 02, you’re already locked into 3G-only mode. Otherwise, type in AT!band=02 and hit enter to set the mode. If you wanted to go 2G-only, the code would be 04 instead of 02. AUtoselect is 00.

Hope this helps! Now I’m cooking along with 2-3 bars of signal (-87 dBm right now) and pulling down these speeds:

Though connection quality is quite a bit more variable than Sprint’s (slower, particularly on uploads) connection at my place…

In comparison, SPrint usually pulls down 1.3 Mbps down, 300-500 kbps up and gets a B on connection quality.

Re: The Case Against Apple

Aug 9

Posted by Ian Littman in General | No Comments

So Jason Calacanis wrote a newsletter/blog post yesterday about how Apple is becoming big, bad, evil, etc. He had some questions at the end. I emailed him my thoughts, but they probably won’t get published that way. So here they are, in reworked form.

Preliminary Notes

Verizon doesn’t use SIM cards. Neither does Sprint. While I think it’d be awesome to see a dual-radio network-agnostic iPhone (like the Blackberry Storm and some new HTC units) I don’t foresee that happening. As for a dual CDMA radio setup that would “bond” two networks together for fast downloads, not gonna happen. The engineering and billing logistics just don’t work out. The best that’ll realistically happen is either an LTE iPhone (I doubt it’ll come out for WiMAX unfortunately) or *possibly* an iPhone “world phone” with CDMA and GSM/HSPA a la the Blackberry Storm if Verizon gets the new exclusive.

Now that that’s off my, and Mike Rundle’s, chest…

Q: Do you think Apple would be more, or less, successful if they adopted a more open strategy (i.e. allowing other MP3 players in iTunes)?

A: At worst, they’d be just as successful. They might be forced to compete a little more on features, especially on the Mac side (where there’s no Windows Media Player and thus no simple way to sync music with a non-iTunes-supported player). However the influx of people using third-party devices on iTunes would make up for any people who might pick a $30 other-brand MP3 player over Apple’s own. Not like those people would buy an iPod in the first place…

All AT&T, All The Time

Nov 10

Posted by Ian Littman in Tech | No Comments

I must say, AT&T has been active and\or in the news lately…

Starting off with the wireless division, we see the iPhone getting a few new laurels to rest on. It has snagged the top spot for most sold US wireless phone this quarter from the Motorola Razr, and also appears to be 2X the reliability of BlackBerries and nearly 3X the reliability of Treos. AT&T has also opened up free AT&T WiFi access to iPhone and other smartphone users. This is particularly cool since the company also bought up hotspot operator Wayport right around ten minutes ago.

Last but not least, 1.1 million customers and a lot of spectrum, towers and other such infrsatructure got traded for a cool $944 million in AT&T’s buyout of Centennial Communications, yet another regional GSM carrier to fall under AT&T’s sway.

UPDATE: Looks like AT&T will be allowing iPhone tethering…for $30 on top of your regular data plan. The transfer limit is 5 GB with this option, and if you’re thinking that the total data cost is equal to that of a dedicated modem, you’re abso-freaking-lutely correct. Ripoff? Yes, but I suspect people will bite. Though Sprint’s network is generally faster, and tethering is only $15 on top of a data plan, which is also $30 on top of a voice plan but also includes everything from navigation to text messaging.

Speaking of WiFi, you get that free with most AT&T DSL/U-Verse plans. Which may be capped. The monthly transfer caps are as follows:

$10-$20, 768K, 20GB (DSL only)
$25-$32, 1.5M, 40GB
$30-$36, 3M, 60GB
$35-$43, 6M, 80GB
$55, 10M, 150GB (U-Verse only)

The caps are a bit biased speed-wise toward the lower-end tiers, but of course cost-per-GB-wise toward the higher tiers. Overages will be $1 per GB. The caps are squarely between Time Warner Cable’s proposed 5-40 GB limits and Comcast’s 250 GB cap. What’s funny about this is that AT&T hs plenty of backbone infrastructure, especially with U-Verse, to allow everyone to download as much as they want. Of coursse, business-class users won’t see these caps, but users in the Reno, NV test market already are, or they’re being grandfathered in at 150GB per month. What’s unnerving is the result if you only qualify for a lower-speed DSL connection due to distance from the CO: low caps, high overages.

Speaking of U-Verse, AT&T has introduced an 18 Mbps tier (1.5 Mbps upload) for $10 more than the 10/1.5 Mbps one, or $65 per month, though people have reported that they’ve gotten better deals by calling AT&T to upgrade. The caveat: the U-Verse service has to share bandwidth with any TV that’s running, and the shared pipe is only 25 Mbit/s wide downstream and 2 Mbit/s upstream. This “profile” is due to the fact that VDSL (the tech upon which U-Verse is based) drops off quickly speed-wise as distance from the VRAD (fiber-fed DSL terminal) increases. The result: if you’re watching TV, you get 14-15 Mbps internet speeds instead of 18 Mbps, though TV quality doesn’t degrade while the internet is being used. No word on caps on this tier; let’s hope they’re to the tune of 250GB…competitors are sure to deploy DOCSIS 3 in response to this new U-Verse tier, and Comcast‘s caps are well above AT&T’s proposed ones.

Last but not least, AT&T is trying to create a video search engine (!?!) in partnership with a startup by the name of Divvio. Once can’t but think that this new service, dubbed Videocrawler, will be a nice tool for chewing up your gigabytes once caps are in place. Why I oughta…
