At present, China's route switches are developing rapidly and widely used in various fields, especially in telecom operators. The BDCOM S3400 series route switch is a new generation of high-performance L3 Ethernet Switching Device developed by Boda communication. The BDCOM S3400 series route switches not only provide enterprises with high-performance, multi-layered solutions, but also provide powerful support for the transition from service providers to data networks.
The BDCOM S3400 series rout

The dedicated indoor coverage system can reduce the load on the macro cellular network and achieve the following effects:
1) The dedicated indoor coverage system can reduce the load of macro cells by reducing the downstream power, thus releasing more system capacity for the outdoor areas. If most or all indoor users in a residential area use a dedicated indoor coverage system, the average power required to serve
higher for users after the two-year lease period.
Second, the current test results of ADSL are good, but in fact, because traditional telecom companies have been using copper for a certain period of time, affecting the activation of ADSL Services. The actual user rate and distance are limited, and more importantly, the ADSL outbound rate is affected. With the emergence of G. lite products, this effect will become more obvious. In this way, it is difficult to meet the needs of communities with h
implementation method is frequency-based coordination and power-based coordination.
Frequency Coordination is simple, that is, dividing the frequency into three equal points. users in the center of the residential area use all the frequency bands, and users at the edge use 1/3 of the frequencies. In this way, the edge user is equal to the frequency score, so there will be no interference. For example, the red, blue, and yellow colors are used by user
What is the building area of a house? How is it calculated?
The building area is also referred to as the expanded area of the building. It refers to the sum of the plane area of each layer determined by the outer wall of the residential building. It is an economic indicator of the scale of a building. It includes three items: area used, auxiliary area, and structure area. Because the building area is the settlement data for calculating the price of co
scheme of "Repeater + Photoelectric conversion module + power Amplifier" can be adopted. Taking the optical fiber as the carrier, the optical signal is converted by the Photoelectric conversion module, and the signal is amplified and output by amplifying module. If a power amplifier is used, the noise coefficient of the device needs to be considered, such as the bidirectional amplifier T-BDA which the Alcatel chooses for the tunnel, and the noise coefficient is 6dB when the maximum gain of the

Access Solution for Optical Fiber Ethernet Switches
The core network device is an optical fiber switch placed in a residential data center or building data center. The optical fiber switch is connected to an Internet edge router or collection switch at a rate of 1000 Mbit/s, connect a residential network to the Internet. The optical fiber switch uses optical fiber and
Beebot is a property agent information management software with multiple functions, simple operations, and high efficiency. It is also a marketing software, the cloud refresh function can be used to automatically refresh the cloud, allowing the brokers to say goodbye to manual refresh. The following describes the main functions of beebot.
The main functions of beebot are as follows:

The CDMA network is completely different from the GSM network. Because the channels and users are no longer separated, there is no difference between traditional coverage and capacity. The larger the business volume of a residential area, the smaller the residential area. In CDMA networks, increasing business volume means increa

ICIC: Inter Cell Interference Coordination, Inter-Cell Interference Coordination technology.
Cell interference is a key indicator that limits cell network cell throughput, especially for cell edge users. Because the Frequency Multiplexing factor supported by the LTE system is 1, meticulous management of inter-cell interference is particularly important.
The ICIC design principle is to increase the throughpu

Description
In a city that is divided into regular blocks by east, west, and North, N residential areas are scattered across different blocks. The X coordinate indicates the east-west direction, and the Y coordinate indicates the North-South direction. The location of each residential area can be expressed by coordinates (x, y. The distance between any 2 points (x1, Y1) and (X2, Y2) in the block can be meas
