Characterizing Backhaul Traffic in 3G Networks Using Real-World Speech

Overview As third generation (3G) services become universally adopted, carriers will need to minimize recurring bandwidth expenses in their radio access network (RAN) while providing media-appropriate QoS. This paper proposes the use of a mobile speech corpus of 1300 recorded voice conversations for analyzing bandwidth requirements. The bandwidth utilization over the UMTS Iub/Iur link layers is studied, taking into account not only voice activity statistics of the speakers from the corpus, but also the effects of background noise, echo, and signaling traffic, as well as vocoder and link update algorithms.

Activity far from frenzied in German UMTS bidding

The second day of bidding for Germany's UMTS licences progressed slowly with candidates only offering $1.3bn by early afternoon. The first day had also progressed slowly with bids only reaching $1.1bn with candidates cautious against about not...

Peter Cochrane's Uncommon Sense: The cyborgs are here

I have experimented with highly sensitive hearing augmentation involving microphones, low noise amplifiers and ear inserts. For me, the worst feature of gradual deafness is a degraded spatial awareness - of which ambient noise plays an important...

IM use 'should be monitored'

However, many companies have also adopted a more stringent attitude toward managing IM use than they have applied to email and phone calls. Sixty-eight per cent allow limited use of email for non-work activity, but only 44 per cent make similar...

Virtualisation: Architectual Considerations and other Evaluation Criteria

In the past several years, server virtualisation technology has moved quickly and firmly into the IT mainstream. Of the many approaches to system virtualisation available in the market today, VMware's hypervisor architecture has gained the greatest market acceptance. This paper examines the architectural issues, solution support, and enterprise readiness required when deploying such a virtualisation solution.
