Multi-antenna Techniques LTE to improve the downlink performance There are five methods of multiple antennas have been defined for the LTE downlink to improve the performance: Receive diversity at the mobile Transmit diversity using SFBC at the eNB (evolved Node B) MIMO spatial multiplexing at the eNB, for one or two users Cyclic Delay Diversity … Read more
Gain is most important thing in wireless communication and if its passive then it will be very useful here I write about antenna gain and diversity gain definition and its effect. Antenna Gains Mobile Station Antenna Portable mobile phones antennas have typically gain of 0 to 1 dBd. Car mounted antenna has a typical gain … Read more
Understanding the current subscriber behavior and trends is a valuable guide for a product manufacturer and operator of the capital investment. In this post a few key observations will be shared via the Internet and existing wireless high speed data transfer. The first observation is: 1. Increased bandwidth translates into more demanding users. This is not … Read more
During detailed design, the main task is to determine the exact type and placement of the Antenna, to ensure sufficient coverage to meet the requirements. During this process, the physical properties of the Antenna must be kept in mind, as they may affect the design of the Antenna system. Many indoor Antennas are available with … Read more
Indoor solutions required? First, to analyze whether the macro cell coverage is enough. Even if the macro analysis of the project and the macro network test-drive network has sufficient coverage, additional site survey should confirm that all the target areas are covered and, more importantly, the fact that the dominant server can be found in … Read more
