Influence of LTE technology on PTN
China and the rest of the world are entering the brand new 4G/LTE era at full speed. As a mobile return technology, PTN faces severe challenges even after years of evolution and maturity. Some of these technological changes are huge enough to trigger a PTN revolution. This article takes into account the deployment of macro base stations and micro base stations, and review
Multi-frequency and ultra-Broadband Antennas must not be underestimated in LTE deployment
According to the latest GSA (Global mobile Suppliers Association) statistics, operators in 112 countries around the world have commercialized 331 LTE Networks. It is estimated that by the end of 2014, the number of Global LTE commercial networks will reach 350. With the ar

Modern mobile communication tends to provide high-speed transmission multimedia services. The birth of LTE family base stations effectively improves the coverage, throughput, and transmission experience of the system in hot areas.
In the standardization process of LTE, the concept and technology of a family base station HomeeNodeB and HeNB came into being. Unlike traditional cell communication base stations
As an evolution after 3G-4G, do you know its technical characteristics? As one of the 4G standard record filing systems, wireless TD-LTE-Advanced adopts the multi-access method, frame structure similar to TD, and wireless MIMO technology. The following is a detailed introduction.
Features of wireless TD-LTE-Advanced Technology
1. Multiple Access Method
The wireless TD-L
Gdbm is installed by default in most mainstream Linux distributions, but in some distributions, you may need to use the Package Manager to install the corresponding development library. For example
In ubuntu, you may need to use the Synaptic Package Manager to install the libgdbm-dev package, because it is generally not installed by default.
DBM data block datum is a type defined by typedef statements. It contains at least two members:
Void * dptr;

LTE user documentation(if there are inappropriate places, please correct me!) )Configure UE MeasurementsThe user measurement configuration activated in the simulation depends on the selected "Consumers", such as the switching algorithm. Users may need to add their own configurations in the following ways:
Directly configured in the base station RRC entity;
Configure the existing switching algorithm;
A new switching algorithm is develo
Network Collaboration of TD-LTE
Is there mutual interference between the TD-LTE and the current 2G system in the adjacent frequency? How can this problem be solved?
A: In actual network deployment, the F-band (1880-1915 MHz) TD-LTE base station will be affected by the stray/blocking/Intermodulation Interference of DCS1800, the Second Harmonic Interference of GSM
Latest Advances in TD-LTE Testing
At present, the first phase of core network, transmission, bearing and security testing work has been completed in the six test fields of TD-LTE. The results meet the test expectations, and all of them have entered the formal test conditions, in the future, the wireless performance, multi-antenna, terminal, indoor distribution system, network management and other aspects of

The RF signal of the radio transmitters output is transmitted to the antenna via a feeder (cable) and radiated out by the antenna in the form of electromagnetic waves. ElectromagneticWhen the wave arrives at the receiving location, it is received by the antenna (only a small fraction of the power is received) and sent to the radio receiver via the feeder.Therefore, it is very important to calculate the transmitting power of the transmitting device and the radiation ability of the antenna in the
