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

The Magic 3 – ‘rescue’ WiFi standards in a Mobile Enterprise.

By

Cisco and Apple provide the benefits of optimized WiFi connectivity and the use of prioritized business applications for iOS devices together with the integration of voice and collaboration to reduce costs and complexity in a world where mobility and connectivity are dependable from each other by giving their users more capabilities than ever before and the demanding needs out of the business.

Intelligence and efficient roaming is automatically configured for optimized WiFi connectivity and business data gets priority regarding prioritized business applications.

Not only iOS devices will work more seamslessly in a Cisco mobile enterprise environment, it is also the speed and powerfullness of these mobile devices which is an eyecatcher in this modern world of mobile enterprise.

Cisco and Apple are very familiar to each other by recognizing each devices in a network infrastructure environment together with enabling special capabilities. Apple devices can easily connect to a Cisco access point which gives the user optimized connectivity together with advanced networking features like Fast Roaming and Quality of Service (QoS).

Business critical apps need more bandwidth but combined with iOS 10 latest features and Cisco’s new hardware and software, the business can take full advantage in delivering great use and experience in business-critical real-time apps, (Wi-Fi) calling and collaboration.

“Cruising” the fast lane for business-critical real-time apps only applies for Cisco-Apple deployments so you can prioritize applications per environment.

Out of Cisco’s new hardware and software, the magic 3 WiFi standards (802.11k, 802.11r and 802.11v) were configured for iOS devices, allowing users to move seamlessly between access points on the same network, transition between them without interruption and reduce the delay of roaming and management overhead.


802.11k – send you list of Neighbors


802.11r – Fast Roaming (Fast Transition) without complete reauthentication


802.11v – BSS Transition sends you the new best access point

 

In summary:
With QoS and 802.11k, 802.11r, 802.11v configured:
* roaming performances will improve in end user browsing and application experience
* reduction in probability of poor audio quality experience
* reduction in network message load from the device beginning roaming
* low battery usage.
