Heterogeneous Wireless Access Networks: Architectures and Protocols


Heterogeneous wireless networking, which is sometimes referred to as the fourth-generation (4G) wireless, is a new frontier in the future wireless communications technology and there has been a growing interest on this topic among researchers and engineers in both academia and industry. This book will include a set of research and survey articles featuring the recent advances in theory and applications of heterogeneous wireless networking technology for the next generation (e.g., fourth generation) wireless communications systems. With the rapid growth in the number of wireless applications, services and devices, using a single wireless technology such as a second generation (2G) and third generation (3G) wireless system would not be efficient to deliver high speed data rate and quality-of-service (QoS) support to mobile users in a seamless way. Fourth generation (4G) wireless systems are devised with the vision of heterogeneity in which a mobile user/device will be able to connect to multiple wireless networks (e.g., WLAN, cellular, WMAN) simultaneously. This book intends to provide a unified view on the state-of-the-art of protocols and architectures for heterogeneous wireless networking. The contributed articles will cover both the theoretical concepts and system-level implementation issues related to design, analysis, and optimization of architectures and protocols for heterogeneous wireless access networks.

Marantz IS301 wireless iPod dock

Marantz IS301 wireless iPod dockWireless iPod docks are not new, but the trend kind of died out leaving us with many tethered versions. Marantz has one of their own to offer with the IS301, a Lucullan wireless iPod dock that transmits both audio and video and includes a receiver with ports for your home theater. Almost every dock-connecting iPod will work and it also features Bluetooth 2.1 for BT-enabled devices. It should hit Japan in January for about $277. Hopefully the US soon after.

Wireless Lark Doorbell alerts you with a twitter

Wireless Lark Doorbell alerts you with a twitterSome doorbells can be downright jarring when a visitor presses the button. Just plain loud and offensive. It can really suck if you’re having a quiet night and you’ve had way to much caffeine. Why not put a little soothing nature into the whole doorbell thing? The Wireless Lark Doorbell will do just that. It’s a fake Lark that will cost you £7.33. The lark has a built in 2W speaker that will sound off with bird noise when guests arrive. The sound of birds chirping can be soothing instead of alarming. Good idea.

Buses equipped with wi-fi are being used to deliver web content to remote rural villages in the developing world.


In rural India and parts of Rwanda, Cambodia and Paraguay, the vehicles offer web content to computers with no internet connection.


The buses and a fleet of motorcycles update their pages in cities before visiting the hard-to-reach communities.


As well as offering popular pages, the United Villages project also allows users to request specific information.

Nikon multimedia Wi-Fi Headset with 8GB & a browser

Nikon multimedia Wi-Fi Headset with 8GB & a browserHere’s an odd one from Nikon, but it’s no camera. The Media Port UP300 and UP300x video headset aims to be a wearable computer. The device basically looks like a pair of headphones with a small display, but has some nice specs. It features up to 8GB of flash memory for videos, music and file storage, Wi-Fi, and even, get this, a full internet browser.

The 300x model, even sports motion control. Browsing may be a challenge, who knows. You can also use the Wi-Fi connection to download audio and video content directly. The 300x will cost you $587. Looks like we are now on our way to becoming the Borg. If the next one requires that you dock yourself in a borg ship, I’m heading for the hills.

Wireless.Foresight.Scenarios.of.the.Mobile.World.in.2015


Wireless Foresight
deals with the development of the wireless communications industry and
technology during the coming ten to fifteen years. Telecommunications
is a global business of enormous proportions and is one of the largest
industries in the world.

Written in a highly accessible and
simple to read manner, this book is based around four scenarios of the
wireless world in 2015. The focus is on the industry (i.e.
infrastructure and terminal vendors, operators, and service developers
and providers) as well as on new players.
  • Uncovers important
    areas for technological research and discusses the critical challenges
    facing industry, for example; the high cost for infrastructure, the
    slow spectrum release, the stampeding system complexity, radiation,
    battery capacity, and the threat of a disruptive market change facing
    the telecommunications industry.

  • Offers a global approach whereby developments from around the world are described.

  • Employs the method of building full-scale scenarios as opposed to just identifying trends and making predictions.
Wireless Foresight
is an invaluable and provocative read for top and middle management,
strategists, business developers, technology managers, and
entrepreneurs in the telecom, datacom and infocom industries alike. It
is also of great interest to financial analysts and academics.
