Berbeda dengan LTE (Advanced), WiMAX II lahir dan didorong bukan dari industri seluler, melainkan dari industri komunikasi informasi. Tentu konvergensi terjadi. Namun ada nuansa yang membedakan teknologi-teknologi ini.

Sepanjang Semester II / 2009 dan Semester I / 2010, IEEE COMSOC telah menyelenggarakan seri seminar 4G Mobile Network Technologies. Tentu WiMAX II adalah salah satu yang selalu turut dikaji dalam seminar itu. Di bawah ini disampaikan salah satu presentasi dari WiMAX II yang beberapa kali telah dipaparkan dalam seminar yang diselenggarakan COMSOC itu.

The first tutorial titled Cooperative Wireless Networking. This tutorial introduces cooperation concept for wireless networks. Cooperation is known as an effective strategy in nature to achieve individual or common goals by forming cooperative groups. As the crossover between nature and engineering has always been fruitful, this tutorial is introducing cooperative concepts for wireless networks advocating mobile devices to cluster in a peer-to-peer fashion. In three lectures cooperation is advocated to overcome the most critical problems in mobile communication, known as energy consumption, security, and higher data rates. The first part will introduce the main rules for cooperation. Whether to cooperate or act autonomously has to be decided by each mobile device individually. Following the rule “The real egoistic behavior is to cooperate”, mutual aid among mobile devices will be applied if and only if it is beneficial for all group members. The second part is presenting cooperation concepts at the different protocol layers from applications to the physical layer. In the last part topics such as social mobile networks, game theory and genetic programming are presented.

The second tutorial titled Next Generation Digital Video Broadcast Standard. It is an overview of the new digital video broadcasting standard DVB-T2. The new standard approved by ETSI provides high definition television over terrestrial links by deploying new error detection codes, new modulation schemes, and news transmission formats.

Titled Basics of Optical Communications and WDM, the tutorial covers the functions and operational characteristics of available optical fibers, transceivers, and specialized passive and active components needed for designing modern optical fiber communication links. It explains the distortion effects that dispersion and nonlinear processes have on signals, defines bit error rate concepts, and identifies measurement equipment and procedures used to verify system operating characteristics. The tutorial also defines wavelength division multiplexing (WDM) concepts, components, and applications. The topics include characteristics of wavelength multiplexers, optical amplifier uses in WDM links, the basics of Raman amplification, and implementation of WDM-based networks.

Ini merupakan kesempatan menarik untuk meningkatkan keahlian para anggota IEEE maupun para engineer pada umumnya. Tutorial ini gratis bukan saja bagi para anggota, tetapi bagi setiap pengunjung. Namun waktu bagi setiap tutorial terbatas hanya satu hingga dua bulan saja, kemudian akan digantikan oleh tema lainnya.

Seluruh tutorial dipaparkan oleh para pakar bidang-bidang yang dilingkupi dalam ruang minat IEEE Comsoc. Setiap tutorial memerlukan waktu antara 2 hingga 5 jam. Tutorial gratis yang saat ini sedang aktif diantaranya:

  • Next Generation Wireless Broadband
    Tutorial ini memberikan landasan yang kuat atas bakuan teknologi broadband wireless, yang meliputi WiMAX II (IEEE 802.16m), IEEE 802.22, dan LTE, dengan berbagai variasi keunggulannya. Topik yang dikaji meliputi layer fisik (PHY), modulasi dan coding adaptif, transmisi OFDMA dan SC-FDMA, sistem multi-antena, layer MAC (medium access control), transmisi FDD dan TDD, serta format frame. Juga dipaparkan kajian atas wireless relay, co-operative network, dan peningkatan kinerja cell edge pada jaringan OFDMA.
  • Generalized DFT for OFDM Communications
    DFT (discrete Fourier transform) merupakan hal yang membangun bagian inti pada berbagai jenis teknologi transmisi broadband, dari xDSL hingga OFDM. Tutorial ini memaparkan Generalised DFT fasa non linear yang baru saja diperkenalkan, yang menawarkan peningkatan cukup besar pada DFT non linear. Contoh-contoh yang dibawakan meliputi kemampuan adaptif GDFT untuk mengatasi degradasi kinerja penguatan daya RF dan kinerja BER. Beberapa metode perancangan GDFT efisien dan kinerjanya dalam skenario komunikasi di dunia nyata juga ditelaah di sini.
  • IPv6 Transition
    Komunikasi nirkawat generasi keempat mengharuskan aliran informasi yang seluruhnya dilakukan menggunakan protokol Internet dari ujung ke ujung. Dengan skala pemakaian komunikasi mobile yang besar, IPv4 tak mungkin lagi dipertahankan untuk pengalamatan piranti mobile di seluruh dunia di tahun-tahun mendatang. Maka transisi ke IPv6 merupakan hal yang harus mulai diseriusi, khususnya bagi pihak-pihak yang akan menjadi pelopor 4G Mobile.
