Wireless Network Hacks & Mods for Dummies phần 10 ppsx

You can attach a telephone handset to the device for the audio portion of the call, which we recommend. Otherwise, you get a fair amount of feedback from the voices coming from the TV being re-fed back into the microphone as originating audio. Lots of companies are doing some sub- stantial research and development trying to come up with a good way to talk to your TV set for just this application. ߜ Power over Ethernet: You’re not always lucky enough to have an electri- cal outlet near your Ethernet cabling port for your remote access point, so products like D-Link’s DWL-P100 and P200 models ( www.dlink.com, $30 to $40) really save the day. You can add power at the front end of the connection and split it back off when you get to the access point. (See Figure 16-7.) The DWL-P200 transfers data on CAT-5e cable pairs 1/2 and 3/6; power is transmitted on unused Ethernet pairs 4/5 and 7/8.

W e always enjoy making lists. Without them, we’d never get anything done. So we think you might enjoy our lists that will help you get more done with your wireless network. In this Part, we give you Top Ten lists designed to tickle your brain and whet your appetite for wireless. First, we list our ten favorite sites for keeping current on wireless trends, and then we answer the most frequently-asked questions of advanced wireless users. 24_595830_pt05.qxd 8/26/05 7:59 PM Page 328 Chapter 17 (Almost) Ten Sites for Advanced Wireless Topics In This Chapter ᮣ Brushing up on wireless (and we’re not talking toothpaste!) with Tom ᮣ Reading up on RSS at CNET ᮣ Finding practically everything at Practically Networking ᮣ Checking out the latest wireless thriller: Gizmodo versus Engadget W ireless news and information is everywhere. Pat’s mom even calls him to discuss wireless articles she reads in her hometown newspaper. These days, wireless is simply an everyday topic for the everyman (and woman). Certain sites, however, we track regularly in order to stay up to speed on the latest and greatest tips, tricks, reviews, news, blogs, pictures, and wacky sto- ries that just make our day more fun and informative at the same time. In this chapter, we tell you about almost ten (we can’t count too well, but our editors keep us honest) key sites to visit if you have questions or just want to see what’s new. We bet you’ll visit them often if you visit them once! No one site will tell you everything you need to know about advanced wire- less topics. At best, you can get great reviews from one site, terrific gadget news coverage from another site, wonderful and responsive forums on another site, and so on. The patchwork of Web site content combines to give you a well-rounded view each day as you seek wireless truth. The wireless gurus are in: Bring on the wireless truthseekers! 25_595830_ch17.qxd 8/26/05 7:58 PM Page 329 Wi-Fi Net News Wi-Fi Net News (www.wifinetnews.com) is an interesting roundup of the wireless topics that intrigue the editors. Because we’re usually intrigued by what they pick to write about, we bet you’ll like it too. Wi-Fi Net News covers a variety of advanced wireless topics, including VoIP and WiMax. They also have WNN Europe, which is a Europe-focused news reporting area of their site. Wi-Fi Net News, like many other sites, now supports RSS feeds. If you don’t know about RSS, you will soon. Most news and information sources (even E! Online, for all you closet Demi/Ashton fans) offer RSS feeds to tell you about the latest news and features on their Web sites. RSS feeds are electronic feeds that contain basic information about a particular item, like the headline, post- ing date, and summary paragraph about each news item on the site. You use a program called an RSS reader, such as NewsGator Online ( www.newsgator. com ) or any of dozens of other free RSS Readers, to reach out and access these feeds on a regular basis. Some RSS readers load into your e-mail pro- gram, browsers, instant messaging programs, and so on. These readers allow you to scan the headlines and click on the ones you want to read. You could set up an RSS reader to access the RSS feeds of each of these sites and stay current on everything wireless. We highly recommend RSS. Tom’s Networking Tom’s Networking (www.tomsnetworking.com) is a go-to source for us and many others. It includes practical advice on wireless issues (“How can I get my wireless notebook to automatically connect to the AP with the strongest signal?”) and fun-loving stories that push the edge of networking (“Building a BlueSniper Rifle – Part 1”). Tom (and there is a Tom) even mimics the For Dummies Part of Tens concept with his “Top Tens” area that details things like the top ten most-read articles, the top ten most popular FAQ items, and more. But what we love about Tom’s is the detailed reviews that show detailed product views and take you through all the aspects of setting up and using the products. If you want to know what to expect with a wireless product, Tom’s Networking tells you the pros and cons of the product, installation issues, and even looks under the hood to cover chips, boards, and all of that techie stuff that we love. If you like this site, check out his other site, Tom’s Hardware Guide ( www. tomshardware.com ). 330 Part V: The Part of Tens 25_595830_ch17.qxd 8/26/05 7:58 PM Page 330 JiWire JiWire (www.jiwire.com) is a terrific online resource for all things hot spot–oriented. We think you’ll be traveling with your wireless gear all over the place, and logging into hot spots is going to become a religious experi- ence for you. What’s great about JiWire’s Web site is that it’s wholly focused on the travel- ing user. JiWire’s goal is to build the world’s largest database of Wi-Fi hot spots — you can find reviews of wireless PC cards, for instance, that are opti- mal for traveling users, not just home offices. There are how-to stories about using VoIP over Wi-Fi on the road. (The news on the site is not homegrown — it comes from Wi-Fi Net News.) JiWire is also branching out to offer services specifically designed for Wi-Fi users on the go. The company recently launched a service designed to auto- matically and securely connect to Wi-Fi access hot spots. You can read more about this in Chapter 10. FreeNetworks.org FreeNetworks.org (www.freenetworks.org) is — you guessed it — devoted to the proliferation of free networks around the world. A free network is any computer network that allows free local connectivity to anyone who wants it. If you have fun with wireless, this organization might be for you. It’s all volun- teer-run, and the people involved believe in the freedom of the airwaves for anyone who wants to log on. Building a community network, as we discuss in Chapter 12, can be quite an undertaking, and FreeNetworks.org provides you with peering agreements, advice, and community discussion groups to help move your community towards wireless communism. What would Lenin say? Robert Hoskins’ Wireless Super Sites Robert Hoskins, a broadband wireless enthusiast, has a series of almost 20 sites all based around the wireless industry — 802.11a/b/g/i, Bluetooth, broadband wireless . . . you name it. Most of these sites are designed to be a capsule on what’s happening on each topic. For instance, 80211info ( www. 80211info.com ) lists the latest news, articles, white papers, research reports, events, books, and other content on, you guessed it, 802.11. Robert also offers some Buyer’s Guides and Business Directories, but these do not tend to be as populated as some other sites. 331 Chapter 17: (Almost) Ten Sites for Advanced Wireless Topics 25_595830_ch17.qxd 8/26/05 7:58 PM Page 331 We like these sites because you can get a concise listing of all the latest arti- cles and news on one topic — without all the extraneous information you find with a Google or CNET search. So if we want to know all the latest Bluetooth articles that have been published in the tech industry, we just hop over to www.bluetoothdailynews.com, and we’re happy. And best of all, his sites support RSS too. Wi-Fi Planet Brought to you by the folks at Jupitermedia, the same people who publish Internet.com, Wi-Fi Planet ( www.wi-fiplanet.com) is a well-rounded news and features site on Wi-Fi topics. We like this site because they always have interesting and useful stories, whether it’s giving advice about hardware (“Used Routers Can Create Whole New Problems”) or about brand-new ser- vices to check out (“Enterprise Authentication at Home”). In particular, Wi-Fi Planet has two areas focused just on WiMax and VoIP to keep you current on those topics. The site also sports wireless reviews, tutorials, and an insights section that gives views on different topics. The forums (which don’t get a lot of traffic) and product listings (which tend to be more commercials for vendors than really meaty listings) are the site’s weak spots. Stick with the news, features, and tutorials for the best use of this destination. Checking In on CNET CNET (www.cnet.com) should be a primary news source (next to this book, of course) for tracking the latest in wireless networking happenings. CNET News is a source reputable enough for even the Wall Street Journal to refer- ence. The Networking sections of the CNET site offer a well-rounded view of news, reviews, software downloads, and buying tips based around the prod- ucts on the market each day. 332 Part V: The Part of Tens Want to find RSS feeds? The Google of the RSS kingdom is Syndic8 ( www.syndic8.com). This is a listing of user- submitted/Syndicat8-authenticated RSS feeds that you can subscribe to in your RSS reader. Just enter your keyword in the Search area and Syndicat8 displays all of the listings of available publications and sources with that phrase in their description. Check it out! 25_595830_ch17.qxd 8/26/05 7:58 PM Page 332 URLs change a lot, but as of the time of this writing, CNET offers Networking and Wi-Fi information at http://reviews.cnet.com/Networking/2001- 3243_7-0.html?tag=co . This part of the site gives you feature specs, reviews, and price comparisons of leading wireless gear. (CNET even certifies vendors listed, so you know they pass at least one test of online legitimacy.) At wireless.cnet.com, the CNET editors summarize their view of what you should be doing wireless-wise in your life, through feature stories focused on wireless use. Overall, CNET is a sound resource for wireless networking news and reviews. We talked about RSS reader programs earlier in the chapter; you can find CNET’s reviews of the popular RSS readers here: http://reviews.cnet. com/4520-10088_7-5143606.html?tag=nav . Practically Speaking Practically Networked (www.practicallynetworked.com) is run by the folks at Jupitermedia Corporation, who you might recognize by all the other sites they run as well, like Internet.com. This site offers reviews, Q&A forums, fea- tures, and tips for the novice wireless reader. If you are buying a piece of gear, you might check out the reviews on this site to see what they found in their practical use of the gear, pun intended. The forums are also very helpful — we’ve seen fairly quick and knowledgeable responses from participants. We like this site, but we wish they’d put more effort into keeping parts of it more current. The troubleshooting and tutorial sections of the site seem very dated, at least at the time of this writing. We don’t recommend those areas. Read About the Gadgets If you have not figured this out by now, we love gadgets. So do you, we bet. So if you love gadgets, you will love these gadget-tracking sites: ߜ Gizmodo ( www.gizmodo.com): Dubbed the Gadget’s Weblog, Gizmodo tracks all sorts of cutting-edge gadgets. We usually see a lot of stuff we want right now, except it’s only available in Asia. But the pictures and write-ups are simply wonderful and you never know what you are going to find. Nothing fancy here, just listings of gadget after gadget. (At the time of this writing, the top piece is a “USB Memory with Ghost Detection” device — it displays a particular LED sequence when a real ghost is nearby! 333 Chapter 17: (Almost) Ten Sites for Advanced Wireless Topics 25_595830_ch17.qxd 8/26/05 7:58 PM Page 333 We think it’s scarier that someone even created a USB storage unit with a ghost detector in it. (Not that we believe in ghosts, mind you. Boo!) Danny’s favorite is the “”iPoo GPS Toilet Locator,” available in the U.K. for finding the nearest loo. ߜ Engadget ( www.engadget.com): Gizmodo was the first major Web pres- ence we know of that tracked gadgets, but then one of the major editors from Gizmodo left and formed Engadget. The site is similar to Gizmodo, but with longer posts and reader comment streams for each article. ߜ EHomeUpgrade ( www.ehomeupgrade.com): EHomeUpgrade has a little broader scope of coverage than Gizmodo or Engadget, talking about software, services, and even industry trends. 334 Part V: The Part of Tens 25_595830_ch17.qxd 8/26/05 7:58 PM Page 334 [...]... routers, 52 attenuation, 31, 90 audio antennas, 262 boosters, 263 cameras, 270 conferencing, 11 MIMO, 263 network, 243 signals, 262 standards, 262 UWB, 19 Wi-Fi, 18, 262–263 wireless equipment, 18–19 Wireless Multimedia (WMM), 263 wireless network, 10 ZigBee, 19 346 Wireless Network Hacks & Mods For Dummies authentication hot spot operation, 221 server security, 139–141 system, 129 authorization, hot... music, 244–246 computers Bluetooth, 17 Wi-Fi, 16 wireless equipment, 16–17 wireless WANs, 17 concentrator VPNs, 171 conference/meeting rooms, 12 connectors, antennas, 112–115 constant wire, 195 convention centers hot spots, 14 convergence, networks, 40–41 corporate remote access roaming hot spots, 162–163 VPN, 162 347 348 Wireless Network Hacks & Mods For Dummies corporate VPNs, 171 corporations hot zones,... local area networks (LANs) about, 24, 40 cameras, 272–274 local service provider Web sites broadband, 57 locating hot spots, 151–155 lossless codecs, 244–245 lossy codecs, 245–246 LucidLink, 140 •M• Mac hot spots, 164–165 Mac OS X monitoring, 97 MacStumbler, 105 Magellan, 215 MANs, 24 media adapters video, 264 metrics monitoring, 90, 93–94 351 352 Wireless Network Hacks & Mods For Dummies metro networks... cards, 46 proprietary internal cards, 48 sleds and docks, 47 USB adapters, 47 VoIP phones, 46 network name, 42 network name (ESSID) monitoring, 96 network providers, 230 Index Network Stumbler channels, 102 filters, 102 SSID, 102 networkability broadband, 64 cable broadband, 67 satellite dishes, 68 networks about, 10, 40 access points, 41–43 channels, 42 convergence, 40–41 encyption keys, 42–43 hiding,...
