Time Warner Announces 4G Wireless Internet Service in Charlotte

Time Warner Announces 4G Wireless Internet Service in Charlotte

Time Warner announced on October 14th, 2009 that they will begin offering 4G mobile wireless internet services in the Charlotte area, they have apparently teamed up/invested in the Sprint/Clearwire network, as well as developed part of their own wireless network build-out. The service is targeted at mobile urban users that will be accessing the network with a variety of devices such as iPods, Netbooks, and Laptops.

The idea of the network is to naturally extend the homeowner services currently being provided by Timer Warner seamlessly into the mobile market, while still providing the well established quality of service that Time Warner has worked so hard to maintain. I could see this wireless network deployment as an initial push for them to eventually be planning to provide a mobile triple-play style service.  Even if that is several years away though, this deployment is giving their current fiber/coax network an immediate additional redundancy, as well as numerous additional bandwidth regeneration/backhaul points throughout the existing network.

The wireless internet service is said to be able to provide speeds up to 6mbit/s downloand bandwidth and part of a mbit of upload bandwidth, almost exactly comparable to the home cable modem service that they currently provide throughout this region. “This is an important part of our strategy to give our customers any content, on any device, anytime, anywhere,” says Carol Hevey, executive vice president of the Carolina region for Time Warner Cable. The first product to launch is Road Runner Mobile, with a monthly charge between $40 and $80 for customers with at least one other Time Warner Cable service.

Comparably, Verizon recently launched the MiFi service on their 3G network in Charlotte, and of course we had to get one to try out! So far we’ve been really happy with the result. Though the bandwidth is a bit slower, 3mbit/s down when I did the last speed test in the university area of Charlotte. The technology of the MiFi is pretty neat as well, the connection is stable and the WiFi signal transmitted from the MiFi device is surprising strong.

Wireless technologies such as these are only going to become more and more prevalent in the immediate future, and as I predict, continue to be targeted only in the densely populated urban centers and major metropolitan areas for at least the next 5 years. Though I must admit that being able to provide guaranteed 6mbit mobile wireless internet services in the Charlotte market is quite impressive. Making a service like this truly affordable is going to be the key, it’s likely not going to be much cheaper until a massive amount of investment is put into additional nationwide infrastructure though. When I get the opportunity to try this wireless service out, I’ll be sure to get an update posted on here for all of you.

Kodak ESP 7

Kodak ESP 7

We normally don’t do product reviews of consumer hardware, but I had to post my frustration with Kodak’s wireless ESP 7 multi-function printer. Kodak touts itself as saving money with its new line of Easyshare printers, but even though the print is cheaper, it seems to run out faster. It is also a problem since the color ink is all in one cartridge – you run out of one color and you have to replace the whole thing. The printer is also loud, and slow to start.

Mine was among the many printers that have issues requiring the unit to be returned to Kodak and often, returned again. The first issue I ran into was “Top Tray Jammed, Pull Tray Out….Top Tray Jammed, Push Tray In…Top Tray Jammed…” error. Pressing “Cancel” got me past this problem, as there is no paper jam. That is just an annoyance, but now I am stuck with an “error 6202” which is apparently because of the scanner motor not being able to move. The reason for this became apparent as soon as I opened the printer up and noticed that a cable had come loose. As soon as I hooked the cable back up, the printer was back to working again. But, now I am out of ink again after I have only printed about 20 pages. Bottom line, avoid these printers at all costs. I have never had this much trouble with a printer. 

Don’t take just my word for it, here are links to other reviews about the Kodak ESP 7:

Even the ESP 5 is apparently flawed:

Graphing Tranzeo Wireless SNMP Stats Using Cacti

If you are trying to graph the link and noise levels of your Tranzeo wireless equipment on Cacti and are running into problems, changes are that you need to download this graph file TranzeoCactiGraph.xml.

Loading this file into Cacti will allow you to create Tranzeo specific graphs for any wireless Tranzeo equipment that may be deployed on your network. Simply make sure that SNMP is turned on in the Tranzeo control panel and you should be ready to start receiving the wireless statistics in Cacti.
