Allowing Errors in Speech Over Wireless LANs

Overview Wireless LANs are becoming commonplace because of their ease in providing mobile communication. As use of IEEE 802.11 continues to expand, support for voice will become a desirable feature. Supporting voice conversations over a packet network is more challenging than over current circuit switched wired networks. These challenges are particularly difficult due to the erroneous nature of a wireless channel. By forcing error-free reception of speech, scarce bandwidth and energy are unnecessarily expended, and the delay of the packets increases. This paper explores allowing bit errors in voice packets over IEEE 802.11 networks. The paper proposes two strategies for allowing these errors and demonstrate that they both result in improved performance.

Intel WLAN can forget about Europe

This standard already operates on the 5GHz bandwidth (5.4 to 5.7GHz) and is designed to carry ATM cells, IP packets, firewire packets and digital voice from cellular phones. IEEE, the standards body behind 802.11a, has no idea when and if the...

Has Gigabit Ethernet come of age?

Even Andrew Rufener, ambassador to the ATM Forum and director of technology for EMEA at Marconi, said: "Service providers are gradually moving away from circuit-switched technologies such as SONET/SDH to packet-switched solutions.

Telco-friendly Ethernet 'ready for action'

Ethernet has seen off all competitors in companies' local area networks (LANs) - with the exception of fibre channel - and is now poised to extend into the service providers' territory. There is plenty of bandwidth in the long-haul networks between...

Peter Cochrane's Uncommon Sense: Circuit or packet, clean or dirty?

The most successful attempts see the prescriptive routing and priority of packets so the end-to-end circuit, although based on packets, rapidly resembles its circuit-switched predecessor. For non-real time applications such as email and delayed...

Peter Cochrane's Uncommon Sense: VoIP wins

I've connected to the internet via wired or Wi-Fi LANs in hotels, office buildings and restaurants. The really big question is: who is going to support the wired, fibre and wireless infrastructure for global data communication if the money is taken...

Peter Cochrane's Blog: VoIP reality check

In my view bandwidth and good quality speech and video are an absolute necessity that will transform more than the ICT industry. A further factor in the telecoms industry is the belief that bandwidth costs money, is in some way precious and should...

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
