4G Americas is an industry trade organization composed of leading
telecommunications service providers and manufacturers. The
organization's mission is to advocate for and foster the
advancement and full capabilities of the LTE mobile BROADBAND
technology and its evolution beyond to 5G, throughout the
ecosystem's networks, services, applications and wirelessly
connected devices in the Americas. 4G Americas, the voice of 5G for
the Americas, is invested in leading 5G development for the
Americas and maintaining the current global innovation lead in
North America with LTE technology.
Emerging technologies such as WiFi and WiMAX are profoundly changing the
landscape of wireless BROADBAND. As we evolve into future generation wireless
networks, a primary challenge is the support of high data rate, integrated multi-
media type traffic over a unified platform. Due to its inherent advantages in
high-speed communication, orthogonal frequency division multiplexing (OFDM)
has become the modem of choice for a number of high profile wireless systems
(e.g., DVB-T, WiFi, WiMAX, Ultra-wideband).
This books presents the research work of COST 273 Towards Mobile BROADBAND Multimedia
Networks, hence, it reports on the work performed and on the results achieved within the project
by its participants. The material presented here corresponds to the results obtained in four years
of collaborative work by more than 350 researchers from 137 institutions (universities, operators,
manufacturers, regulators, independent laboratories and others – a full list is provided in Appendix
B) belonging to 29 countries (mainly European, but also from Asia and North America) in the area of
mobileradio. Theobjectiveofpublishingtheseresultsasabookisessentiallytomakethemavailable
to an audience wider than the project. In fact, it just follows a ‘tradition’ of previous COST Actions
in this area of telecommunications, i.e. COST 207, 231 and 259.
Wireless metropolitan area networks (WirelessMANs) is emerging as a promising
BROADBAND wireless access (BWA) technology to provide high-speed, high bandwidth
efficiency and high-capacity multimedia services for residential as well as enterprise
applications. It is observed that WirelessMAN (e.g., WiMAX) is even regarded as a 4G
technology. For the success of the WirelessMANs, international standardization organiza-
tions are very actively specifying the standards IEEE 802.16, ETSI HiperMAN and Korea
WiBro.
