Since 2013, the global TD-LTE network has entered a period of vigorous development. The latest statistics show that as of May 2013, 17 TD-LTE networks have been commercialized worldwide, and more than 40 operators have announced clear TD-LTE commercial plans, with the number of global TD-LTE users exceeding 3 million. However, since the current TD-LTE network deployment is mainly concentrated in the F-band (1880 ～ 1920MHz) and D-band (2500 ～ 2690MHz), or upgraded from the original TD-SCDMA network, how to choose the appropriate one for different site construction scenarios Antennas, while ensuring optimal network performance, have become a major challenge for operators. This article hopes to provide different ideas for operators to solve the above challenges by analyzing different network scenarios and combining different antenna performance.
At present, the main TD-LTE antennas include FA / D dual-band independent ESC antennas and FAD broadband antennas. Among them, the FA / D dual-band independent electrically adjustable antenna is mainly applicable to the scenario where the FA band (F band: 1880 ~ 1920MHz, A band: 2010 ~ 2025MHz) and the D band (2500 ~ 2690MHz) are jointly fed. The FAD wideband antenna supports any frequency band within the entire FAD frequency band, and is suitable for scenarios where there is sufficient space in the sky, and the FA and D frequency bands are independently deployed.
The following table will analyze the antenna deployment in two typical scenarios:
A tablet computer is an electronic device that integrates mobile commerce, mobile communication and mobile entertainment, with a touch recognition LCD screen, handwriting recognition and wireless network communication functions. At present, the tablet computer has become the most popular electronic product.
1.In appearance, the tablet computer looks like a large-screen mobile phone, or more like a separate LCD screen.
2.In terms of hardware configuration, a tablet computer has all the hardware devices of a traditional computer, and has its own unique operating system, compatible with a variety of applications, and has a complete set of computer functions.
3.Tablet PC is a kind of miniaturized computer. Compared with traditional desktop computers, tablet computers are mobile and flexible. Compared with notebook computers, tablet computers are more compact and more portable.
4.Tablet PC is a digital notebook with digital ink function. In daily use, you can use the tablet computer like an ordinary notebook, take notes anytime and anywhere, and leave your own notes in electronic texts and documents.
