Wireless Networking Technology: From Principles to Successful Implementation Review

Average Reviews:

(More customer reviews)Are you a wireless networking system developer? If you are, then this book is for you! Author Steve Rackley, has done an outstanding job of writing a book which aims to give the reader a detailed insight into the wide variety of wireless networking technology available today.
Rackley, begins by introducing you to the logical and physical architecture of wireless networks. In addition, the author describes the basics of wireless communications. The author then focuses on what perhaps is the most important operating scale for wireless networks: The Local area Network. Next, he takes a detailed look at wireless networking technologies on the personal area scale, including Bluetooth, wireless USB, ZigBee, IrDA and Near Field Communications. Then, he looks at how the metropolitan area networking challenges of scalability, flexibility and quality of service have been addressed by wireless MAN standards, particularly WiMax. The author continues by looking at four emerging technologies: wireless mesh routing, network independent handover, gigabit wireless LANs and cognitive radio. Finally, he provides a quick reference guide to some of the key online information sites and resources relating to wireless networking.
This most excellent book provides the reader with sufficient depth to gain an understanding of the fundamentals and diversity of the principles of wireless networking technologies. Perhaps more importantly, this book will serve as a foundation on which, a discussion of the principal aspects of wireless network implementation can be grounded!

Grace Digital GDI-IRD4400m Wireless Internet Radio Featuring Pandora, NPR On-Demand and SIRIUS Review

Average Reviews:

(More customer reviews)This radio is an excellent product. It set up in a couple of minutes and has proven to be reliable and very easy to use. My single complaint is the headset and stereo jacks on the device. There is an AM-like static present when I plug in headphones or connect in my stereo. The noise on the headphones is 'tolerable', but the stereo connection was terrible. I e-mailed Grace Digital Radio Technical support with my problem. They replied and stated that I shouldn't be having static on the audio output (I figured that out all by myself). They then suggested that I try alternative radio stations (AM and FM) and advise if I had a similar issue. I explained that the radio was not an AM/FM radio but internet and that all types of stations on the internet exhibited the same problem. They never replied back to me. I've attempted a couple of times to get a response from them to no avail. In one attempt, I suggested that, perhaps I should return the radio and obtain one from another manufacturer. Still no reply. In a word, customer support for this product - stinks.

Grace Digital GDI-IR1000 Wi-Fi Internet Radio Featuring Pandora and NPR On-Demand Review

Average Reviews:

(More customer reviews)I just bought this radio several days ago and absolutely love it! Very, very simple to operate, and took literally 15 minutes to set up (and I employ both 128 bit WEP and MAC filtering). In addition to the myriad stations available, I've linked my Internet Radio to my Pandora account; this allows the unit to play music directly from my Pandora radio stations. I can even create new Pandora radio stations directly from the Grace IR (although it is quicker and easier to do this from a computer). The sound quality from the onboard speakers is excellent. I have my unit connected to my home stereo system via the Grace IR's Headphone output into L-R inputs on my receiver. This is an excellent, excellent buy! I am considering purchasing a second unit for my bedroom. I highly recommend this unit.

Wireless Crash Course Review

Average Reviews:

(More customer reviews)This book is a must buy for newcomers to the wireless industry or for those who just want to know how wireless systems work. I gave this a 4 instead of a 5 because I was expecting a little more digital wireless information. This book gives an excellent explanation of analog cellular, the foundation of wireless as we know it today. There is a section later in the book that goes over digital wireless, (GSM, CDMA, TDMA). I think differences between analog and digital protocols should be discussed throughout the book, not just one section at the end. The author does an excellent job of taking a very complex system and filtering out the technical jargon to give the readers a book that has a balance of technical information that is easy to read and easy to understand. This is a great book for your money, and it is definitely worth your time to read it.

Myine Electronics IR001 WiFi Internet Radio Adaptor Review

Average Reviews:

(More customer reviews)This little internet radio device is jumping-up-and-down cool! Five minutes after opening the box I was listening to a newscast from France (in French, course) then jazz from Australia, rock from Iceland and later opera and classical music from Italy. How cool is that?
The device doesn't have any speakers of it's own, but comes with and RCA jack that you connect to your receiver, TV, boom box or even a little clock radio. There's an adapter included with a smaller plug for the later. There's a little LCD screen that you operate with a small remote control that's also included. The first thing I did after I connected it to my receiver was to turn it on and go through the menu and set the date and time and hook up to my home WiFi network. It came with a manual which is very well written and understandable, but I didn't even need it. When I clicked on "Network" the name of my WiFi network popped up, I selected it in the menu, entered the password, and it connected in about 15 seconds and it was ready to go. It was super easy. And since it uses Wi-Fi to connect, you don't need a computer. This goes directly to your receiver.
The IRA is classy looking, even though it's made of plastic. I posted some photos of it. I set mine of top of the Blu-ray player in my stereo cabinet. The display screen is easy to read and the menus easy to navigate. You can search by country, genre of music, stations, or new or popular stations. There is an automatic software update feature through the Wi-Fi network or you can check yourself to see if there are any updates available. It also has volume control on the remote.
The sound is crystal clear and since I connected it to our home theater system, I could hear the bass booming out through the subwoofer and music through all the speakers. I also tried it with the adapter, plugged into a little clock radio and that worked fine too. Connected to the receiver the stations I've listened to so far were CD quality. I could imagine this at a Caribbean themed party, playing reggae music directly from that part of the world, or a romantic French dinner with music from France. No matter what your taste in music, there is something here for everyone. And if you're learning a foreign language, what better way than to listen to a newscast from that country?
I love this thing! It's a great addition to our home entertainment system.

Grace Wifi Radio (ITC-IR1000B) Review

Average Reviews:

(More customer reviews)I've been listening to internet radio for more than 5 years, and have been exploring the purchase of a stand-alone wifi radio for the last two. The market has either been high-end ($300+ for the Roku Soundbridge or the Revo Pico), products with flaws (check the reviews for the Torian InFusion) or not a true standalone device (requiring that your computer be on, works only with open networks, etc.).
When I saw the Grace Wifi Radio at the $170 pricepoint, I decided to give it a try. I opened the box about an hour ago, and within 10 minutes had it set up, working with my WPA protected AirPort network. Sound is good; this isn't hifi, but like 90% of internet listeners I'm no high-end audiophile. The stations available through the Reciva server simply blow my mind (think thousands instead of the hundreds I normally look through on iTunes). I can see myself playing with this for weeks, cranking the dial like a kid with his first shortwave.
Note this is a very simple radio; only 5 presets, no equalizer, no dancing visuals, no ipod dock..... And I haven't tested its capability to play audiofiles sent by iTunes (that's not what I bought it for). But all in all I'm very pleased, and while decent wifi radios will probably be available below $100 before the year is out, I'm glad I didn't wait.
