《通信信息报》12月03日报道，4G牌照一旦发放，运营商将大幅增加资本开支，未来三年内，4G累计投资额有望突破3000亿元，其拉动的投资规模将可能达到万亿。点评：4G被寄望为扩大内需，催生新经济增长点的重要抓手，但4G发展不能只是电信设备业的盛宴。需要未雨绸缪的是，在新一轮投资建设高潮后，如何运营考验着各方的智慧。

ACC is a driver assistance system that is incorporated into a vehicle to help the driver maintain constant speed and keep safe distance from other vehicles. ACC automatically manages vehicle speed if there is any obstruction in front of the car and warns the driver in an emergency. The purpose of installing an ACC system is to enhance safety and efficiency. It is designed to help prevent accidents caused by driver error such as poor reaction time and drowsiness. This system is highly efficient in warning a driver whenever required and in providing improved comfort during long drives.

Crystal oscillators are electronic circuits that generate electrical signals with precise frequencies. To generate these electrical signals, they make use of a vibrating crystal made of piezoelectric material. The frequency generated is used to keep constant track of time and provide a timely clock signal for electronic integrated circuits. This frequency is also used to stabilize frequencies for radio transmitters and receivers. Crystal oscillators find their application in a large number of devices such as cell phones (smartphones and feature phones), tablet computers, wristwatches,clocks, FM radios, medical electronic equipment, automotive systems (tyre pressure monitoring systems and anti-braking systems), and personal computers.

Head-mounted displays or helmet-mounted displays are augmented reality devices, which display images through small optic computer displays. These display devices are worn on the head like a helmet, with optic computer displays in front of one eye or separate optic computer displays for each eye. Head-mounted displays consist of an image source, collimating optics, and a mechanism to mount the device onto the head. These displays are being used in many applications such as medical visualization, in military vehicles for viewing sensor imagery, airborne workstations for aircraft simulation and training, and fixed and rotary wing avionics. Head-mounted displays can be used in virtual reality as well as augmented reality applications.

Frequency references with a low phase noise and a low temperature-induced frequency drift are important components for navigation systems, wireless communication systems,and signal processing applications. As is well known, crystal oscillators (XOs) and temperature compensated crystal oscillators (TCXOs) based on AT-cut quartz dominate this market because AT-cut quartz has outstanding frequency-temperature performance and long-term stability. However, there are drawbacks and fabrication limitations for quartz-based resonators related to down-scaling for future applications. In addition, the material properties of quartz limit the integration of the frequency references and the complementary metal-oxide semiconductor (CMOS) circuits on a single chip.

Vertical-cavity surface-emitting lasers (VCSELs) are key optical sources in optical communications, the dominant source deployed in local area networks using multimode optical fibers at 850 nm. The advantages of VCSELs include wafer-scale testing, low-cost packaging, and ease of fabrication into arrays. The ease of array fabrication is particularly useful for spacedivision-multiplexed (SDM) links using multi-core fiber or fiber arrays. VCSELs emitting in the 1.3 μm to 1.6 μm wavelength regime, also known as long-wavelength VCSELs, are highly desirable for the rising applications of data and computer communications, in addition to optical access networks, optical interconnects and optical communication among wireless base stations.The potential advantages over conventional distributed feedback (DFB) and distributed Bragg reflector (DBR) lasers include much lower cost due to smaller footprint and wafer scale testing,and significantly lower power consumption.

Continuing scaling of transistors as density approaches the terascale regime (1012 devices/cm2) requires evaluating new devices that can perform on several metrics beyond density scaling, such as cost savings, performance improvements, and energy efficiency. A comprehensive review and evaluation of potential new devices is performed. Metrics such as processing cost, plan-view area scaling, and stage delay are benchmarked. One of the most promising devices, tunneling field effect transistors, is also the most confounding, as simulation and experimental results are orders of magnitude apart.

Modern silicon technology offers unprecedented spatial and temporal control of electrons with high levels of integrated complexity. Integrating nanophotonic functionality onto silicon should then allow us to extend this level of control to photons. Resulting nanooptoelectronic systems will inevitably create new functionality, which not only enables next-generation technologies like optical interconnects, but also gives rise to yet unforeseen applications.

The combination of mobility with wireless networks greatly expands the application space of both robots and distributed sensor networks; such a pervasive system can enable seamless integration between the digital and physical worlds. However, there are a number of issues in both robotic and wireless sensor network (WSN) fields that demand research, and their integration generates further challenges.
