Question:
In a rectangle, there are n Cities '*'. Now all N cities need to cover wireless networks. If a base station is placed, it can cover at most two adjacent cities.How many base stations can be placed to ensure that all cities are
An original Mini-game inspired by gold miners and big fish. In fact, this game has been played for two weeks and is only uploaded until now. Some bugs have not been fixed yet. No way. Busy.
Recently, I am engaged in a large-scale webgame with
software-controlled Antenna Array (composed of multiple independent antenna units), the Wireless Access Point of Ruckus can send signals to connected wireless devices. The antenna's targeted pairing operation can be completed in real time through the software, and different antennas can be independently adjusted by parameters.

Currently, wireless LAN is widely used and plays an important role in various fields. Here we will mainly introduce the application of wireless LAN in schools and solutions to some problems for your reference. Kingsbury and Emy of sport, two schools near Birmingham Bordesley Green, will use better wireless technology for information technology sharing and discussion.
Ruckus, a Wi-Fi technology in the enterprise wireless LAN market, today announced tha
example, what if a problem occurs with your controller? Some Access Points can enter the independent mode, while others cannot, "Schatt said. "Moreover, there are significant differences in antenna technology. companies like Motorola and Ruckus have invested a lot of energy in the antenna field to make full use of the advantages of MIMO technology, some other co
This is for the only free mini PCI-E slot models, such models are also more common, especially in some international brands of models. With the mini pci-e slot, according to the method of the previous period to add 3G network card and mobile card slots, this time only need to install 3G antenna is done.

By adopting polarization diversity technology, low-cost PCB substrates can be used to create Wireless LAN equipment (WLAN) antennas with good receiver performance. This article will describe how to use the latest 3D electromagnetic field (EM) simulation tool to design and simulate a 2.4 GHz orthogon
The concept of radar was formed in the early 20th century. Radar is a transliteration of radar, abbreviated as radio Detection and Ranging. It is an electronic device that uses microwave band electromagnetic waves to detect targets.
Composition
The specific use and structure of various radars are different, but the basic form is the same, including five basic components: the transmitter, the transmitting antenna, the receiver, the receiv
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
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
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?
"The more the antenna coverage, the more the antenna more signal stronger, in short, the more the antenna routing is better
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
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.

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

The mainstream standard wcdma/td-scdma/cdma2000 of the third generation mobile communication system adopt the Code Division Multiple access method, CDMA Code division multiplex System is a disturbance restricted system, in the transmission of information, there are multiple access interference, multipath interference and far-near effect. Any technology that can improve the anti-jamming performance of the system can improve the capacity of CDMA system, in this paper, the key anti-
industrial chain will be transferred to China.
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
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
In recent years, the increasing demand for mobile data services has promoted the acceleration of LTE network commercialization. Throughout the world, LTE commercial networks are still dominated by lte fdd, but with the gradual development of their networks, users and businesses are increasing, lte fdd network frequency resources, insufficient capacity and other issues will gradually become prominent, and TD-LTE network in the spectrum resources have more resources, can effectively alleviate the
technology of visual distance requires that there must be no obstacle between the sender and the receiver to be visible to each other.
For a network with a visible distance, the problem is that most people have not considered this scattering phenomenon. I have seen many people look out the window, and if they can see the target, they will think that they have a very clear visual distance network. However, as the signal spreads, the signal strength is weakening. If you want to receive all the si
