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

Received today Aruba’s coffee cup:

Aruba present

I want to thank Aruba for their effort to make Wireless Field Day very successfull every year!

Special Thanks to Sean Rynearson, Özer Dondurmacıoğlu and Rocky Gregory

Unplugging the last cord, ..Welcome Microsoft Lync !

RIP Phones

But before the last cord can be unplugged this should be well prepared starting by a pilot, WiFi should be reliable, meaning Clean RF – High Density Coverage by AirWave  – WiFi Redundancy..and finally the Enterprise Voice Rollout

But why Microsoft Lync?

.It has the best user experience of any UCC offering

.. Mobile apps for smartphones & tablets

…Seamless integration with MS Office productivity suite

….Tight intergration with Aruba WiFI

Fast Lync Adoption:

Lync SDN API should be used to optimize WiFi Roaming, Priority Over The Air and WiFi Call Loadbalancing, on the other hand Lync SDN API intergrates with Aruba WLAN for proactive monitoring, By the way Lync SDN is all about QoS flow and collecting call data

Key components of the Lync topology are:

  • Lync Front End Pool
  • Lync SDN manager
  • Active Directory

Fluke Neworks was the first presenter during Wireless Field Day 7.

I am glad that they started the presentation about their history of innovation, starting in y2000 with their world’s first WiFi field tester; Waver Runner…and after 14 years the lauch of 802.11ac within AirMagnet…they truly keep the indispendable WiFi networks alive.!

AirMagnet Mission: Networks leaders need to redesign their WLAN’s to address the proliferation of personal mobile devices in the workspace, deploy WLAN’s that currently support three devices per user so that they are robust enough to support Voice,Video and Collaboration.

The biggest challenge for the new 802.11ac technology is not a technical one but making a business case and the roll out should be in a gradual way in “bandwidth or capacity hungry” locations.

But a lot of customers are still in a investigation phase before the transition to 802.11ac can start. Those who have deployed  802.11ac have a lot of connection problems, due to fact that the client devices are not 802.11ac compliant.

Fluke Networks offers the next products with 802.11ac support;  AirMagnet Planner which has a great visualization  coverage and performance, it can determine number, location and configuration of AP’s; AirMagnet WiFi Analyzer Pro, this is a toolkit to measure expected performance before roll outs. AirMagnet Survey Pro; a WLAN deployment solution that enables users to measure true 802.11ac end user experience.

Fluke Networks has the industry’s only complete lifecycle solution to speed up design, deployment and troubleshooting effiency.

Secure your WLAN from flying Drones ….BIG BROTHER IS WATCHING YOU! …Drone Detection…

Introduced by Fluke Networks on June 30, 2014. Drones potentially snoop with video and have the potential to impact entreprise WiFi privacy…

..maybe in future drones can help us out with WLAN site surveying…

..a few weeks to go before I am heading up to San Jose, California, USA…seeing some old friends and newbies at Wireless Field Day #7.. Aruba and Cisco are not new to me because I met them during WFD#4 in February 2013.

New to me during Wireless Field Day,  AirTight and Avaya, so I am glad to see them presenting..

AirTight is doing a good job in the US but it is a pity that they are not that familiar in Europe, well lets say in BeNeLux..cause their focus on security and social analytics is perfect, but that can not be the eye catcher to approach the European market…I like to hear from them how they gonna change this..

@Anthony (Paladino): it was great meeting you last year in Amsterdam, …@Hermant (Chaskar)..finally we will shake hands..nice meeting you…!

HC

@Avaya, nice to be the new presenter… I am curious to see your presentation about IP Telephony over Wireless and more ..Welcome on board!

Radio Link Efficiency

By · Comments Comments Off

A radio interface is bandwidth constrained because it is bound to use limited spectrum. Although 3G networks claim to provide bit rates up to 2 Mbps, it is still a far cry from the 52.8 Mbps a Very high Data rate Digital Subscriber Line (VDSL) can offer on a single twisted-pair copper loop. Similarly, bit rate of 11 Mbps in WLAN is no comparison to 1 Gbps of the gigabit Ethernet (IEEE 802.3). Therefore, it is highly desired to use the available bandwidth as efficiently as possible, so as to give the user a decent performance for IP compared to the wired world. Cellular operators pay a significant amount of their deployment costs in acquiring a spectrum. Therefore, radio link efficiency is also highly desired for cost savings.

One approach to improving efficiency for some IP protocols is to use header compression. A problem with IP is namely its large header overhead.

Bandwidth efficiency can also be improved by performing compression on IP payloads. Sometimes IP payloads are already compressed (images, audio, video, “zipped” files) by the applications or are already encrypted above the IP layer. For payload compression the best bandwidth efficiency can be achieved if application-level compression techniques are used extensively. The challenge is to ensure that almost all the applications have a compression mechanism and are using them over wireless links.

Dormancy and Paging

By · Comments Comments Off

Cellular networks support dormancy for mobile nodes that are idle and not engaged in active conversations. Dormant mobile nodes do not perform frequent updates of their network location information at the cell level; they wake up only when they move across a larger network area.

The main benefit of dormancy is to save power on the mobile nodes, since frequent location updates to the network drains the power. The network does not keep track of dormant nodes at the cell level but within a greater network area where the mobile is currently dormant. The mobile nodes remain dormant until there is a need to wake up and update their exact location to the network, for example when the mobile users initiate calls
