The weather in Guangzhou in June kept switching between the raging sun and the heavy rain. It was hot and windy and wet, as if the outdoor places in Guangzhou had become saunas, but in the face of this grenades The enthusiasm of many manufacturers and spectators at the 2016 Guangzhou International Lighting Exhibition has not been relentless, and it is very lively.
Compared with the lighting manufacturers that did not lose the enthusiasm of Guangzhou in June, the recent lighting industry seems to be spent in the cold winter. Even though some sub-divided lighting markets are still warm, it is difficult to cover up the overall decline of the lighting industry. According to Xiaobian and some exhibitors, the number of exhibitors at today's Guangya Exhibition has decreased compared with the past, but when asked if they are worried, it is not as pessimistic as I expected. In the view of some exhibitors, these years are the elimination of the lighting industry, just like brushing out a large number of outdated products that can not keep up with the development of technology. This will better reflect the value and strength of the retained enterprise.
In this year's Guangya Exhibition, no matter how domestic enterprises are compared with the homogenized lighting products in the past, this year's relatively demonstrated product design and product features.

In addition to highlighting its COB products in this exhibition, LG showed us the latest optical communication technology in terms of intelligent control. LG engineers used the mobile phone with its special APP to set the light in the exhibition hall. Illuminating the camera of the mobile phone allows the mobile phone to accurately position the indoors while pushing the user with a technical demonstration of nearby products.

With the rise of 4G network construction in the world, multi-network operation has become the main melody of the network development of operators. Qingdao Unicom's current network status is 2/3/4g coexistence. In the optimization and adjustment, the ideal situation is that 2/3/4G network can have its own independent antenna, so that RF adjustment is convenient and flexible. However, due to the constraints of antenna installation site resources, space shortage, construction cost and other factors, common antenna strategy can only be adopted in network construction in many cases, which not only saves resources, but also brings difficulties to RF adjustment and multi-network coordination optimization. In view of this situation, the Network Optimization Center of Qingdao Unicom combined with the actual situation of the network, made a statistical study of various common antennas, and made an analysis and adjustment plan according to the network demand. There are a large number of 2/3/4G common antenna sites in the current construction. According to statistics, the proportion of common antenna in the current network is over 60%, which is higher than the national average level. Three, the current total antenna situation classification 1. 2/4 g share a common antenna by 2/4 g RRU type of antenna and antenna panel. 2. 3/4G common antenna is divided into: the beautification antenna cannot be adjusted independently, the circuit board antenna cannot be adjusted independently, and the common antenna can be electrically adjusted independently. 3. 2/3/4/G common antenna is divided into: 2/3/4/G common antenna cannot be independently adjusted, and 2/3/4/G common antenna can be independently electrically adjusted. Four, common antenna formation reasons and advantages and disadvantages
