Richard Jhon How Many Various Gains brought by the MIMO for LTE When we talk about LTE RF Planning then the one question in mind is that what about MIMO gains. Here I write Different Gain in LTE like MIMO Gains and Gains which brought by multiple antenna technology and By MIMO Like Power Combine Gain, Array … Read more
LTE parameters Equipment related parameters include the base station, antenna, and terminal. The link budget parameters vary with the base stations, antennas, and terminals of different vendors. These parameters affect the link budget result. As a result, the downlink is unaffected in most scenarios. List of LTE parameters in LTE link Budget LTE Transmit Power LTE Power Combining … Read more
Calculation for Body Loss and Feeder Loss for LTE When we RF Planning in LTE then Losses are one of most important factor to take in calculation for predication coverage. Below you find how Body loss and Feeder loss calculation for LTE. Body Loss : Body loss indicates the loss generated due to signal blocking … Read more
Search Window in cdma is essential parameter to work cdma technology because based on search window as defined in system mobile needs to take important decision for available bts. Search window play main role in mobile switch on, handoff, access etc. let’s check in detail. Why Search Window? A CDMA system employs the synchronized detection … Read more
Here I write about Pseudo-Noise Code and what its use Pseudo-Noise Code its two type and Pseudo-Noise Short code is identification for each BTS and Pseudo-Noise Long Code is Identification of each user. Let’s understand basic. A pseudo-noise code (called PN code in short) has properties similar to a noise sequence. It is actually a … Read more
Penetration loss in LTE Penetration loss in LTE indicates the fading of radio signals from an indoor terminal to a base station due to obstruction by a building. For an indoor receiver to maintain normal communications, the signal must be sufficiently strong. The indoor receiver obtains radio signals in the following scenarios for Penetration loss: … Read more
LTE Ray Tracing Model The LTE Ray Tracing Model involves analyzing electric wave propagation by using the ray tracing method and obtaining the field strength of received signals through theoretical calculation. Some LTE network uses the higher part of the UHF band such as 2.3 GHz and 2.6 GHz. The wavelength of the radio wave … Read more
Okumura-Hata Model for LTE The Hata Model for Urban Areas, also known as the Okumura-Hata model for being a developed version of the Okumura Model, is the most widely used radio frequency propagation model for predicting the behavior of cellular propagation in built up areas. This model incorporates the graphical information from Okumura model and … Read more
LTE Standard Propagation Model The standard propagation model is a model (deduced from the Hata formula) particularly suitable for predication in the 150MHz~3500MHz band over long distance (1Km<d<20Km) and is very adapted to GSM900/1800, UMTS, CDMA2000, WiMAX and LTE technologies. This model uses the terrain profile, diffraction mechanisms (calculated in several ways) and take into … Read more
Propagation model LTE- Cost231-Hata Model Cost231-Hata model can be used in macro cells as the propagation model. The application range is as follows: Frequency band: 1500 MHz to 2000 MHz Base station height: 30 meters to 200 meters. The base station must be higher than the surrounding buildings. Terminal antenna height: 1 meter to 10 … Read more
