With the continuous development of modern communication technology, mobile communication has entered the era of LTE. As of press time, 152 LTE networks have been deployed around the world, and it is expected to reach more than 300 in 2014. Many mobile operators will face 2G networks such as GSM, CDMA, WCDMA, CDMA2000, TDS-CDMA and other 3G networks and TD-LTE, LTE-FDD and other networks. Many problems such as inter-system interference and smooth transition of later network technologies. Mobi Antenna is committed to becoming a global mobile operator's antenna feeder solution partner. It has officially released a series of LTE converged networking antenna products and solutions to help mobile network operators effectively solve the above problems.

LTE Converged Network Antenna Series Products
LTE converged networking antenna products are divided into beamforming LTE converged networking antenna series and MIMO LTE converged networking antenna series according to different technologies used in LTE network standard.

Key technologies and product features of LTE converged networking antennas:
1. Broadband
Broadband has always been one of the important development trends of antenna technology, especially for LTE converged networking. This is because LTE networks in different countries and regions in the world are allocated different spectrums. In addition, operators operating 2G, 3G, LTE and other networks at the same time will also obtain a series of discrete spectrum combinations. Under this premise, broadband-designed converged networking antennas will maximize the flexibility of network deployment, reduce the difficulty of antenna selection, reduce the number of purchased models, reduce antenna inventory, and prepare for a smooth upgrade and transition later.

2. Intelligent
Smart antenna technology is one of the key technologies in LTE networks. By applying smart antenna technologies such as MIMO and beamforming, it can effectively improve system robustness, improve spectrum efficiency, suppress interference, and increase network throughput. Mobi's LTE converged networking antenna products support smart antenna technologies such as MIMO and beamforming to provide stable and reliable support for high-speed wireless network connections.
3. Independent ESC
In the multi-network common antenna feed deployment process, due to the different wireless propagation performance in different frequency bands, it will bring great difficulty to network design and network optimization. For example, under the conditions of the same transmit power and the same downtilt angle of the antenna, the difference between the average value of the outdoor 2.1GHz band and the 2.6GHz band is about 2dB, and the difference between the average value of the indoor level is about 5dB. In the case of common antenna feed construction, the difference between the optimal downtilt angle in the 2.1 GHz band and the optimal downtilt angle in the 2.6 GHz band is about 2 degrees. If the same downtilt setting is adopted, the network performance will drop sharply. Therefore, in the process of LTE converged networking, it is particularly important to independently adjust the downtilt of each frequency band.
4. Informatization
With the large-scale deployment of ESC antennas and beamforming antennas and the gradual application of centralized network management technologies, the informatization of base station antennas has received increasing attention. If the antenna configuration information such as the antenna sector, the electronic downtilt angle range, the electronic downtilt angle, and beam forming weights cannot be properly and efficiently managed, network coverage will deteriorate. The Mobi antenna information storage solution stores the configuration information of the LTE converged networking antenna in the antenna in advance, and automatically reads the configuration information of the corresponding antenna through the base station equipment during site configuration, which can realize automatic antenna configuration and management, which greatly reduces the The complexity of site configuration avoids possible errors in manual settings, and will play an important role in improving network performance, improving efficiency, and reducing maintenance costs.
Transmission And Distribution Pole
Steel poles are commonly used to carry several types of electric power lines, distribution lines and lighting system. Distribution lines carry power from local substations to customers. They generally carry voltages from 4.6 to 33kV for distances up to 30 miles, and include transformers to step the voltage down from the primary voltage to the lower secondary voltage used by the customer. A service drop carries this lower voltage to the customer's premises.
