LTE UE Accessibility Verification and Speed Scaling

UE Accessibility Verification If the best cell on the LTE frequency have banned or are protected, up to exclude This cell from cell selection list. In that case may consider…

Small notes on Connection Re-Establishment Procedure in LTE

Here I write some small notes on connection Re-Establishment procedure in LTE. In a number of cases of failure (eg failure of radio link failure of teaching RLC unrecoverable error,…

Important OFDM characters for Wimax

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…

Which OFDM Parameters Used in WiMAX

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…

Slow Fading Margin in LTE with example of standard deviations in slow fading

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…

Salient Future for Mobile WiMAX

WiMAX is a wireless broadband solution that offers a rich set of features with a lot of flexibility in terms of deployment options and potential service offerings. Some of the…

Guard Band Requirement in LTE

Here I write on simple how guard band requirement for LTE for 2 option. Guard band requirement LTE verses GSM and guard band requirement LTE FDD verse LTE TDD Guard…

Analysis of Background Noise in LTE RF

Assume that the eNodeB receiver’s IF bandwidth is Bw (unit: MHz), and the eNodeB receive noise figure is Nf (unit: dB), The equivalent noise level of the eNodeB receiver is…

Advance Future for Mobile WiMAX

Orthogonal frequency division multiple access (OFDMA): Mobile WiMAX uses OFDM as a multiple-access technique, whereby different users can be allocated different subsets of the OFDM tones. As discussed in detail…

LTE KPI Measurement Methodology and Acceptance Procedure

Here I write in simple word on LTE KPI Measurement Methodology and its Acceptance Procedure. As it’s for only at network start up stage and now a day worldwide so…

OFDM Receiver and How it work for LTE?

The receiver is like in any other radio system the more complicated part. In radio systems and of course also OFDM there are two special points a receiver has to…

What is SC-FDMA and how it works in LTE?

One of the major drawbacks of an OFDMA system is, that the transformation of a complex symbol mapped sequence (e.g. BPSK, QPSK, etc.) onto a small set of subcarriers produces…
