Mobile-broadband users are demanding spontaneous access to video content, a higher-quality experience and more convergent mobile services than ever before. During the London 2012 Olympic and Paralympic Games, around 50 percent of search requests in the UK were from mobile devices. The US broadcaster NBC (National Broadcasting Company) also reported that more than 45 percent of online video streaming of the games was delivered to mobile devices (Figure 1) . Subscribers like to be able to consume content anytime, anywhere. As a result, new business models are emerging in which the line between fixed and mobile is becoming indistinct. Service providers – especially over-the-top (OTT) players and content aggregators like App stores, Netflix, Amazon and so on – are making premium content available anytime, anywhere on a variety of devices. Mobile network operators (MNOs) are being challenged by the need to give consumers what they want, while preserving the economics of their networks and creating new opportunities for revenue growth.

User interest in mobile TV services is growing thanks especially to the rapidly evolving multimedia capabilities of mobile terminals. Mobile operators are thus eyeing mobile TV services both as a new source of revenue and as a way of increasing customer loyalty. This article looks at some key components of a mobile TV solution that capitalizes on the capabilities of third-generation (3G) networks – in particular, built-in support of unicast and broadcast transmission, which fosters and sustains a strong uptake of service.
Long Term Evolution (LTE) is the latest buzzword on everyone’s lips, but are you as conversant with the LTE architecture as you would like to be, or — more importantly — need to be? Would you like to find out more about LTE, but have little time to devote to it? If so, this paper will help get you up to speed in no time. Originally published as a chapter in the most comprehensive LTE reference book available, LTE — The UMTS Long Term Evolution: From Theory to Practice (Wiley 2009), this paper provides a short, but comprehensive, overview of the 3GPP Release 8 LTE network architecture and interfaces, showing how it can be deployed in an optimized and efficient manner. Engineers involved in the design of LTE interfaces and network equipment, as well as those involved in the first deployments of this new technology, should find this paper invaluable.
