Another Ultra-Wideband Startup Folds TZero Technology the latest to implode... Ultra-Wideband (UWB) is a radio technology noted for its potential to offer blazing speeds at very short ranges (great for in-home HD distribution over wireless or coaxial). Unfortunately UWB has been bogged down in a standards war for many years, and now a slew of startups promoting the technology have been folding. Last November, UWB startup WiQuest closed its doors and laid off the company's 120 employees, and this week sees the death of Ultra-wideband startup TZero Technologies. Each time we post a story about UWB's decline we get an e-mail from a UWB startup telling us the technology is very much alive and kicking -- though we're not sure we will this time. UWB also faces being made irrelevant by 60Ghz technologies created by companies like Sibeam.

kudos:1 | fail UWB, my wife walking in line of sight will kill speed by 75%. Its like IR on steroid, god help you if you loose LOS. | |

UWB can be used over wired connections as well, its not just a wireless protocol. It basically allows much higher throughput over something like Coax, which was one of the benefits of it. Of course, it can(could have?) also be used wirelessly as well.

Mount Airy, MD | Is This Cost Effective If you are doing in-home video distribution or networking, why not just run the coaxial or the ethernet cable instead? Both are solid, relatively future-proof technologies and are not terribly hard to work with.

2 edits | Re: Is This Cost Effective I'm currently wiring my home with cat6 ethernet, coax and phones and it's a pain in the ass to cut holes in the wall, drill and fish wire.
You can skip running wires through the all, but wires that are left laying on the floor are a tripping hazard, and securing them with tape leaves glue behind to clean. Other methods are ugly.
Not to mention that those people who won't do it themselves will have to pay someone and it's not cheap.
Wireless is the ideal solution for many people. | |

I'm certainly a fan of wireless, but it's no panacea either. 2.4 GHz is so crowded, you can't really get the promised 300 Mbit rates and electronics manufacturers have raced to the bottom to strip MIMO out of their designs to save a quarter for the 3rd antenna. The Wi-Fi consortium is disgusting: it's 2009, why is 802.11n still "DRAFT"?

Mount Airy, MD | I feel your pain. I had the same issues running the wires in my house as well. I would run 4 Cat-5e cables to each room, along with a coax cable. I got a lot of experience in fishing wires and doing drywall patching as a result but I will tell you it is worth it.

kudos:4 | Given the choice and ability to use both, I'd prefer wired over wireless but I'd also do both. I'd prefer wired connections for my desktop and obviously my servers but a laptop just isn't meant to be tethered by a cord. And then there are times where wireless is your only option. Right now I'm in a rental house. I'm sure the owner wouldn't have any issues with me running Cat5e/6 through his walls but I certainly wouldn't be able to take it with me if I move nor would I get anything out of it other than usage.
In this case I use wireless exclusively (save for whatever is near the router that I can plug in like the HTPC) and I'm quickly realizing this isn't the greatest solution. For example, I can't reliably stream a standard 45 minute, 350 meg TV show from my HTPC to my laptop (or vice versa). But if I copy it I'll have it in 5 minutes and can watch it just fine from my local drive. I know if I were to plug the laptop into the router I could do it just fine which leaves the wireless as the culprit. | |

I don't have these problems with my wireless devices on my network or on the network I setup at my girlfriends. | |

kudos:4 | Re: Is This Cost Effective I wouldn't doubt the AP is the issue. It's always given me problems but I thought I'd fixed them. Ever since I've had it (got it for free so can't complain too much) if you enabled WEP or WPA it would crash and force you to do a factory reset on it. I finally got it flashed with the newest firmware and it doesn't do that anymore but I wouldn't put it past being the culprit. | |

| said by pnh102:If you are doing in-home video distribution or networking, why not just run the coaxial or the ethernet cable instead? Why do we have wireless networking currently? Because one solution doesn't fit all situations. It can be a real PITA to retrofit a house with wired connections easily so that cables don't show and you aren't having to make access holes in drywall all over the place. Not everyone lives in a 1 story ranch with a basement or crawlspace. | |
