The Definition of Interleaving is simply encode logical channel for error protection and security.lets understand how interleaving works in gsm. Having encoded, or error protected the logical channel, the next step…

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…

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,…

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…

Free space indicates an ideal, even, and isotropic medium of space. When electromagnetic waves are transmitted in this medium, no reflection, refraction, scattering, or absorption occurs. Propagation losses are caused…

Here I list out some important OFDM characters for Wimax. Let’s check it in detail. OFDM Pros and Cons: OFDM enjoys several advantages over other solutions for high-speed transmission. Reduced…

Calculation Angular Spread and Coherence Distance is very easy let’s see. So far, we have focused on how the channel response varies over time and how to quantify its delay…

The fixed and mobile versions of WiMAX have slightly different implementations of the OFDM physical layer. Fixed WiMAX, which is based on IEEE 802.16-2004, uses a 256 FFT-based OFDM physical…

Shadow fading indicates the fading brought by obstruction due to a building or a natural feature. Shadow fading changes slowly, and is thus called “slow fading”. Statistics repeatedly show that…

Here I write Interference Margin in simple word and basic definition of interference margin in LTE. Let understands it. Interference margin accounts for the increase in the terminal noise level…

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…

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…
