IME/China 2016The IEEE 802.11ac and 802.11ad specifications both promise to deliver increased capacity, speed, and performance in different ways, allowing users on-the-go to enjoy even their highest-data-rate applications.

Recently, the Ministry of Industry and Information Ministry issued a notice, The 41st Institute of China Electronics Technology Group Corporation (CETC 41) declared 2016 anuual “next-generation broadband wireless mobile communication network”, National Science and Technology Major Project - “R12 LTE-Advanced for the terminal integrated test instrument development”, “5G base station high-frequency broadband RF filter test sample test system” project was approved.

As the national teram of electronic test technology, CETC 41 began to declare “National New Technology Broadband Wireless Mobile Communica-tion Network” major project in 2009 and successively undertook the TD-SCDMA Enhanced Technology Terminal Integrated Tester, TD-LTE Wireless Integrated Tester, TD-LTE Advanced Air Interface Monitor, TD-LTE-Advanced Terminal Tester, LTE-Advanced MIMO Vector Signal Analyzer, LTE-Advanced Empty-port Monitoring and Analysis, TD-LTE TTCN Extened Test Set Meter & TD-LTE Raido Interface Test System etc covers 10 major national projects. Technology system cover TD-SCDMA to TD-SCDMA enhancement, LTE to LTE enhancement (LTE-A), product coverage terminal testing, base station testing and certification testing. From the beginning of 2015, CETC 41 actively tracking research 5G new technology, has successfully developed a variety of millimeter-wave front-end devices, componets, the development of a variety of new 5G waveform options, the first to launch multi-band 5G millimeter-wave communication system, Millimeter-wave communication video transmission services, signal test function, walk in the international forefront.

Focus on the 2016 4G/5G major project, CETC 41 composed of chief experts as the core of the reporting team, through the innovative display of CETC 41 test areas of the overall strength, the feasibility of the program, technological innovation, financial budget and other advantages, and strive to theoretically. There are reasoning, technically validated, there is evidence of innovation, the industry has plans.

LoRaWANTM is a Low Power Wide Area Network (LPWAN) specification intended for wireless battery operated Things in a regional, national or global network. LoRaWAN targets key requirements of Internet of Things suhch as secure bi-directional communication, mobility and localization services. The LoRaWAN specification provides seamless interoperability among smart Things without the need of complex local installations and gives back the freedom to the user, developer, businesses enabling the roll out of Internet of Things.LoRaWAN network architecture is typically laid out in a star-of-stars topology in which gateways is a transparent bridge relaying messages between end-devices and a central network server in the backend. Gateways are connected to the network server via standard IP connections while end-devices use single-hop wireless communication to one or many gateways. All end-point communication is generally bi-directional, but also supports operation such as multicast enabling software upgrade over the air or other mass distribution messaes to reduce the on air communication such as multicast enabling software upgrade over the air or other mass distribution messages to reduce the on air communication time.Communication between end-devices and gateways is spread out on different frequency channels and data rates. The selection of the dta rate is a trade-off between communication range and message duration. Due to the spread spectrum technology, communications with different data rates do not interfere with each other and create a set of “virtual” channels increasing the capacity of the gateway. LoRaWAN network server is managing the data range from 0.3 kbps to 50 kbps. To maximize both battery life of the end-devices and overall network capacity, the LoRaWAN network server is managing the data rate and RF output for each end-device individually by means of and adaptive data rate (ADR) scheme.National wide networks targeting internet of things such as critical infrastructure, confidential personal data or critical functions for the society has a special need for secure communication. This has been solved by several layer of encryption:

- Unique Network key (EUI64) and ensure security on network level- Unique Application key (EUI64) ensure end to end security on application level- Device specific key (EUI128)

EZU participated the China International Con-ference & Exhibition on Microwave and Antenna (IME/ China 2016) as an exhibitor on October 2016 at Shanghai Everbright Conven-tion & Exhibition Center. Because 60GHz transmission suffers from large attenuation when propagating through physical barriers, this usage model is different from the

other IEEE 802.11 standards. Low-power transmissions will not propagate very far. This is considered an advantage, as it reduces the likelihood of co-channel interference and increases the potential density for frequency re-use. Another perceived advantage of limited range is the reduced opportunity for “theft” of protected content by eavesdropping on nearby transmissions.

While IEEE 802.11ac is an extension of the existing 802.11n specification, IEEE 802.11ad represents a completely new paradigm. Today, the 2.4 and 5Ghz wirless bands for the earlier 802.11 standards are heavily congested. They also lack the capacity to deliver the extreme data rates required for emerging business and consumer applications. The multi-gigabit data rates required for uncompressed high-definition multimedia transmissions - including known futures like 4k and 8k digital cinema (3840 x 2160 and 7680 x 4320 pixels respectively) and three-dimensional (3D) video streaming - must be accommodated in a different way.Ultimately, data capacity is tied to modulation bandwidth. And extreme data capacity calls for a large spectrum allocation. The simplicity of high-volume manufacturing demands that this modulation bandwidth should be a small percentage of the transmission frequency. The global unlicensed band that already exists at around 60GHz (where multi-gigahertz modulation bandwidths are practical) meets that requirement.

The unlicensed requency allocations at around 60GHz in each region do not match exactly. But there is substantial overlap. At least 3.5GHz of contiguous spectrum is available in all regions that have allocated spectrum.In summary, IEEE 802.11ac and 802.11ad both provide much higher data throughputs than their predecessors. Yet they have much differenct potential uses. IEEE 802.11ac is an evolution of previous WLAN capability. It gives the “unwired office” the ability to compete directly with gigabit wired systems while offering much better layout and connection flexibility. In contrast, IEEE 802.11ad is a new solution that provides ad-hoc short-range connectivity in support of extremely high data rates.
