Wireless IP, The Killer Application !?

My website and thesis captures the essential elements in the convergence path of wireless networks and Internet protocols resulting in the new paradigm of "Wireless IP." It covers all the important 1G/2G cellular technologies that I have seen in the past decade, along with 3G and 4G, Wireless Local Area Network (WLAN) technologies,including modifications required in protocols, architectures, and framework in virtually every area such as QoS, security, mobility, and so on.

The thesis can be useful for anyone who is interested in the convergence of the wireless and IP networks and for them who need to understand how packet data services and IP work in the wireless world. Furthermore, the thesis represents my views and opinions , based on my technical understanding and experience in these areas

Because the increase of higher system capacities and data rates provided by latest and proposed wireless network technologies, and their closer integration with the Internet enabled by the IP technologies used in these wireless networks are enabling many new ways for people to communicate.
Also people on moving vehicles (e.g. cars, trains, boats and airplanes) may access the Internet or their enterprise networks the same way as when they are at their offices or homes. They may be able to surf the Internet, access their corporate networks, download games from the network, play games with remote users, obtain tour guidance information, obtain real-time traffic and route conditions information.

Wireless networks are evolving into wireless IP networks to overcome the limitations of traditional circuit-switched wireless networks. Wireless IP networks are more suitable for supporting the rapidly growing mobile data and multimedia applications.
IP technologies (such as Mobile IP) are the most promising solutions available today for supporting data and multimedia applications over wireless networks. IP-based wireless networks will bring the globally successful Internet service into wireless networks. The mobile or wireless Internet will be an extension to the current Internet.

Advanced mobile data and multimedia applications such as; MMS, play games in real time with remote users, Voice over wireless (VoIP calls) and broadcasting of audio and video advertisements to mobile phone users such as: advertiser supported phone calls, Wireless IP-enabled radio and watch TV, will grow very fast. New IP broadcasting techniques such as DVB-H (Digital Video Broadcasting for Handhelds), will make it possible to bring video broadcasting services to handheld receivers.

In particular, the growth of advanced mobile data and multimedia applications such as Voice-over-IP (VoIP) help increase multimedia traffic over the wireless networks significantly. Thus, Wireless IP can also be a killer sometimes. Therefore future Wireless IP networks can only be able to service those mobile data and multimedia applications without congestions in the Wireless network, if those Wireless IP networks are ready for it. In other words, "those networks need to be controlled (e.g. by QoS parameters or other specific protocols) end must have enough bandwidth to support all this types of services. Wireless networks and the IP technologies within those networks have to be reviewed and evolved constantly.

Remark these words:
The traffic on broadband wireless networks will be increasingly IP

Future of wireless broadband with a fully mobile lifestyle

Posted by: | Comments Comments Off on Future of wireless broadband with a fully mobile lifestyle

Radio will win. The only question is when and what? In the end, not even that. Wireless is better than wired: it’s quicker to deploy, costs less to maintain, has less to go wrong and is far more flexible. Wherever there’s a choice between the two technologies, wireless wins. In the early days of telephones they were used to deliver music and news to subscribers, but as soon as broadcast radio came along the economics of one-to-many proved overwhelming. Open air is always cheaper than buried copper.
The lead broadband wireless technology at the moment is WiMax, 802.16’s market-friendly name. Promoted at the moment as the key technology for remote, rural and otherwise unwireable locations, it promises up to 70Mbps and up to 70km range. It won’t reach this in practice, but the engineering behind it is building on the enormous amount of experience the industry has from 802.11b and other wireless deployments. It’ll work well enough.

802.20 is another broadband wireless standard, which focus on mobile users. Designed to deliver around 1Mbps to devices on the move at speeds of up to 250kph, the standards committee have been looking particularly closely at the way it works with 802.11. It’s a lovely idea, being able to switch from hot spot to high-speed mobile service and back again without noticing, even if nobody can quite explain why it’s such a similar idea to 802.16e. WiMax uses a slightly different set of frequencies and has some slightly more restrictive speed limits.
The mobile phone industry is anxious not to be left out. It invented mobile data, after all, even if it’s been bad at working out how to sell it or upgrade it much past the 9600bps with which GSM was born. Even though the faster data rates of GPRS, Edge and 3G networks have been hindered by indifferent coverage, the next generation is already being prepared. High Speed Downlink Packet Access (HSPDA) is Nokia’s big idea, and is promoted as being capable of boosting 3G speeds to 10Mbps or even more. It lives alongside existing installations, just as Edge does with GSM, and is just as dependent on the networks getting it right.

The third generation of wireless broadband will be the final integration of the telephone and data networks. You can already have a voice over IP phone that looks like a mobile phone but uses a combination of the SIP protocol and Wi-Fi to route your calls over the internet whenever it finds a hot spot. Add the mobile broadband stuff, and that phone will not only act as a mobile broadband terminal but it will act as a local gateway across 802.11 and the forthcoming Ultrawideband standards.
It is funny that one of the primary benefits touted for the 3 and 4G wireless mobile networks by the wireless carriers will be their ability to broadcast Audio and video advertisements to mobile phone users such as: imagine, advertiser supported phone calls, Wireless IP-enabled radio and watch TV.
The economics will demand less and less human management of the system and put more and more smarts in the boxes themselves.

There are a few issues to be addressed before we can achieve a fully mobile lifestyle:
Powerful, dependable clients: Mobile devices must be easy to use, secure, light and easy to carry, with design features to suit the user’s needs and personal tastes. They must work reliably wherever the user takes them, and they must have the power to access and support robust, secure applications.
Connectivity: Early wireless devices and networks had limited coverage and range. For full mobility, users must be able to connect easily, regardless of device or locale, and they must be able to roam without interruption across wireless networks and hotspots in their homes, schools, businesses, and public spaces.
Mobilized applications: The mobile lifestyle requires a new class of applications that use location and user profile information to securely deliver customized, personalized service to users across a diverse array of devices and networks.
