The first Optoelectronics Week - SEMOPTO, in 1991, had as main purpose to provide researches, students and professionals involved in this technology an opportunity to exchange information. Since then, companies - such as CPqD/Telebrás, Telemig (Telemar), ABC-XTAL, CTBC (Grupo Algar), Fotônica, AsGa, Microeletrônica, AGC Optosystem, Shachin Cury, Lucent Technologies, Leucotron and institutions like CTA-ITA, Unicamp, Unesp, CETUC-RJ, CEFET-PR, UFMG and EFEI (Unifei) - have been participating of the event.

In 1998, the SEMOPTO became an international biennial event. Lecturers from Germany, Chile, Canada, Italy and France, as well as Brazilian specialists, joined it.

In 2000, the event was entitled "Telecommunications International Week" and gave national and international experts a unique chance to discuss the most recent issues from the telecommunications area.

In 2004, the conference was named "IWT - International Workshop on Telecommunications". Important keynote speakers, such as Prof. Dr. Pascal Lorenz, Ethevaldo Siqueira and Prof. Dr. Antônio Alfredo F. Loureiro, participated of the event at Inatel. Several papers and tutorials were presented in 10 different technical areas. IWT'2004 offered a business center where participants could show their products and services, besides tourist and cultural activities in the south of the State of Minas Gerais.

The 2nd edition of the IWT happened in 2007 and turned out to be a forum to exchange new ideas and information. 54 technical papers, authored by researchers from 6 different countries, were presented in 9 technical areas. These papers were chosen between 109 papers submitted from 9 different countries by 55 reviewers who took part in a committee of evaluation. In addition, 4 tutorials and 3 talks were presented by distinguished scientists, covering the hot topics in the telecommunications area at that time.

In its 3rd edition, in 2009, the workshop was held at Ericsson's headquarters in São Paulo. 56 technical papers, written by researchers from Canada, Dubai, Australia, USA, France, Italy, Germany and Brazil, covered the main subjects of the telecommunications world. The keynote speakers were Dr. Pascal Lorenz, from the University of Haute-Alsace/France, Dr. Roberto Saracco, director of Future Centre/Telecom Italy and Dr. Otto Strobel, from the Esslingen University of Applied Sciences (FHTE)/Germany. The Technical Program Committee counted on the participation of professors from the School of Electrical and Computer Engineering from Unicamp to organize the event. The IWT'09 was organized by Inatel in partnership with SBrT, IEEE-MG and Ericsson. CNPq and companies like Linear, Ativa and Sense cosponsored the event.

The edition of the IWT in 2011 happened at Vivo in Rio de Janeiro. A total of 64 papers were presented by authors from Brazil, Germany, Australia, Canada, Turkey, Peru, France, Sweden, Saudi Arabia and Hungary.

    Speech Theme: From WhiteSpace Enabled Rural Broadband to Cognitive M2M

    Speech Description: Regulators all over the world have realized the importance of WhiteSpaces. WhiteSpaces are the un-used or under-utilized portions of the spectrum. There is an on-going debate on licensed vs license-exempt use of this spectrum. Currently 73% of the people in the world do not have internet access. Nearly 3.5 Billion people live in rural areas with hardly any internet availability. License-exempt use of WhiteSpaces enabled through Cognitive Radio (CR) technology has the potential to change all that and benefit many emerging economies such as Brazil. Other Machine to Machine (M2M) applications will drive up the volumes. WhiteSpace spectrum can support a wide variety of applications including regional and rural area broadband access, local area networks, hot-spots, health-care applications, cellular off-load, smart utility networks, remote control and monitoring applications, home-land security, disaster-recovery etc. Skeptics exist but recently, CR related research has seen an explosive growth all over the world, and software radio defined test-beds and prototypes are being tested and deployed in many parts of the world already. The first part of the presentation will describe ideas and results on machine learning based cognitive communications in White as well as the Gray space. The second part of the talk will focus on IEEE 802.22 Standards and WhiteSpace Alliance activities to promote this eco-system and other standards such as 3GPP / LTE, IEEE 802.19.a, IEEE P1900, IETF etc.

    Further Information on WhiteSpace Alliance: The mission of the Whitespace Alliance (www.WhiteSpaceAlliance.org) is to promote the development, deployment and use of standards based products and services as a means of providing broadband capabilities via TV band and other emerging WhiteSpaces. By promoting the use of standards, the Alliance will enable companies to provide broadband connectivity at reasonable cost. The WSA will also act as an enabler of the emerging white spaces ecosystem through educational activities and helping to put in place interoperability, conformance, and compliance testing to make sure that our member stakeholders get the needed information & collaborations to succeed both in the market place and with regulatory requirements. WhiteSpace Alliance will promote the use of IEEE, 3GPP and IETF Standards for use in the WhiteSpaces.

    Further Information on the IEEE 802.22 Standard: IEEE 802.22 systems will provide broadband access to wide regional areas around the world and bring reliable and secure high-speed communications to under-served and un-served rural communities, which are estimated to include nearly half of the worlds population. The IEEE 802.22-2011 is the first IEEE 802 Standard for operation in the Television (TV) Whitespaces, defined as the available or un-occupied TV channels. It is also the first IEEE Standard that focuses on broadband connectivity in rural areas where most vacant TV channels can be found, thus helping to bridge the digital divide. IEEE 802.22 Working Group is the recipient of the IEEE SA Emerging Technology Award. This new standard for Wireless Regional Area Networks (WRANs) takes advantage of the favorable transmission characteristics of the VHF and UHF TV bands to provide broadband wireless access over a large area up to 100 km from the transmitter. Each WRAN could deliver 22 Mbps to 29 Mbps, depending upon the country of deployment, without interfering with reception of existing TV broadcast stations. IEEE 802.22 incorporates advanced cognitive radio capabilities including dynamic spectrum access, incumbent database access, accurate geo-location techniques, spectrum sensing, regulatory domain dependent policies, spectrum etiquette, and self-coexistence for optimal use of the available spectrum. The new IEEE P802.22b amendment proposes to support enhanced broadband and monitoring applications.
