I'm sure everyone knows about the three major wireless 3G standards. Therefore, there is a unique and advanced technology in the TD wireless technology, which is different from the other two technologies-smart wireless technology, that is, smart antenna technology.
The Smart Antenna, formerly known as the Adaptive Antenna Array AAA and Adaptive
data, wireless optimization mainly includes the following aspects in the engineering hardware.
1. Relocation of the base station. The main point is to adjust some unreasonable base station to give full play to the function of the base station and achieve the coverage target. If a base station antenna is in front of a tall building seriously blocked, a base station antenna hanging high, resulting in seriou
Latest Advances in TD-LTE Testing
At present, the first phase of core network, transmission, bearing and security testing work has been completed in the six test fields of TD-LTE. The results meet the test expectations, and all of them have entered the formal test conditions, in the future, the wireless performance, multi-antenna, terminal, indoor distribution system, network management and other aspects of the TD-LTE system will be carried out gradua

With the development of China's routing industry, it has also promoted the wide application of multi-functional wireless routers. The following describes the performance characteristics of functional wireless routers. The rapid development of wireless networks over the past few years is obvious to all, although there is still a certain gap with foreign countries, but we are very optimistic about the domestic wireless network prospects, here do not talk about what 3G,
Broadband is undoubtedly one of the network standards that people are pursuing. When dial-up surfing is adopted and broadband is gradually popularized, we can predict the development of today's wireless networks, wireless Broadband Access technology will eventually become the most popular wireless network technology.
Broadband Wireless Access is favored by the industry for its fast and flexible networking and easy upgrade. However, there are still many problems such as the establishment of pract
I. Test conditions
The beacon tower method is also known as the conventional far-field method. It is a common method to test the antenna pattern in the conventional field.
This is the simplified frame of the antenna tested by the standard tower method.
In the conventional far-field method test [20], to ensure the test accuracy, the following test requirements should be met:
1) the distance between the rec

Wi-Fi, WiMAX, and 3G technologies have their own advantages. However, through analysis, we can see that if one of the three technologies has its own shor
The following is a small series for everyone to collect the "No line by the knowledge misunderstanding" all content, if you like small series of recommendations, please continue to pay attention to learning.
More antennas, better routing?

For example, the received mobile phone signal is very strong (dynamic range test), very weak (refer to sensitivity testing), and receive error rate in interference conditions (such as adjacent channel selectivity, blocking, intermodulation, and stray. This part of the test assumes that the base station does not support diversity. If the base station supports diversity, the Diversity function should be disabled and each antenna sho
data connection Performance drops.
The beauty of modern Wi-Fi devices is that they can be used together, so you can build networks with the best devices of the same type. For example, my network uses routers from one manufacturer, antennas from another manufacturer, printing services from a third manufacturer, and wireless customer devices from several different companies. You can think of it as a wireless United Nations: global cooperation makes your online life easier.

Wireless LAN
Wireless LAN is a product of the combination of computer networks and wireless communication technologies. Generally speaking, wireless local-area network (WLAN) provides all functions of the traditional wired LAN without using traditional cables, the infrastructure required by the network does not need to be buried in the ground or hidden in the wall, but the network can be moved or changed as needed. It is also called a local area network because the transmission range is affected
In the cellular mobile communication system, the antenna is the converter of the circuit signal and the space radiation electromagnetic wave, and is the key component of the mobile communication system.From 2G to 4G, the mobile base station antenna has undergone omnidirectional antenna, directional single-polarized antenna
Faults are also emerging during the use or maintenance of wireless networks. Here we will introduce you to several detailed fault instances. The following articles will explain in detail.
The operating frequency of a wireless LAN (WLAN) is generally 2.4 GHz and belongs to the category of microwave communication. The transmission feature is linear and visible, that is, visual communication and contact methods. This shows that rain, fog, walls and other obstacles can affect the transmission qualit
Mobile communications in the world's great success, driving the development of a variety of broadband wireless technology, the world's wireless technology is stepping into the broadband universe. At present, 3G technology has been able to achieve mature business, WiMAX has become a new hotspot, other short-range broadband wireless technology is also emerging.

As the frequency band increases, antenna deployment becomes a major challenge in LTE construction. Under the overall deployment policy of TDD/FDD hybrid networking, the network is constantly adjusted to meet the development needs, such as visible coverage, variable region, and dynamic capacity adjustment. The operator hopes to ensure that one deployment of the antenn
