What is Carrier to Interference plus Noise Ratio in LTE

LTE is designed to operate in environments where there are peripheral interventions. Link performance degrades as the C/I (i.e. Carrier interference ratio) is reduced, however, it may be acceptable in places with zero or negative C/i. every site and sector LTE systems operating on the same channel so that they can receive interference from all … Read more

What is Frequency Reuse and Resource Block reuse in LTE

LTE sites deployed by using 3 sector. Each sector operates on the same carrier frequency. Nomenclature for this reuse pattern is 1 x 3 x 1. This range of frequency reuse represents a number of sites in a template re-use, the number of sectors in each site, and the number of channels on the site. … Read more

What is Smart Antennas in LTE

What is smart antenna? Smart antennas are antenna arrays with intelligent signal processing algorithms that identify spatial signal signatures, such as the direction of arrival of the signal, and calculate the following beamforming vectors and locate the beam antenna on the mobile / target. Why Need of Invent Smart antenna? At the beginning of wireless networks … Read more

What is CPE Antenna Variations in LTE

A couple of differences may exist between the CPE and device specifications  the alleged targets. The differences are mainly due to two factors not normally thought of in the design process. • Works in Los scattering • Not optimal positioning of CPE When the RF design it is important to understand the characteristics of the … Read more

What is Side and Back Lobes in LTE antenna

Side and back lobes are regions in a template where the “directions” the antenna may be of benefit, except for the maximum rate. System engineer Note these characteristics with downtilting antenna as part Lobe (petal, which appears above the horizon in the vertical model) can lead to interference. Mechanical downtilting antennas will directly affect the … Read more

What is effect of Antenna Beamwidth in LTE

What is effect of Antenna Beamwidth in LTE The antenna beam width is measured in degrees between half power points ( -3 DB) compared to the main axis of the petals of the antenna. -3 DB point of reference power (DBM) or voltage (dBv). Beamwidth is expressed in terms of a horizontal (Azimuth) and vertical … Read more

Definition of Front to Back Ratio for LTE antenna

Definition of Front to Back Ratio for LTE antenna Front to back ratio is an important characteristic of directional antenna antenna. Is the ratio of power radiated from a corner with maximum radiation radiation levels at 180 degrees (the back of) from that point. Front to back the ratio is usually expressed in terms of … Read more

What is Polarization, Gain and Power rating in LTE Antenna

Antenna Gain in LTE Antenna Antenna gain is the ratio of the maximum radiation in a specified direction, a reference antenna in the same direction for the same power input. Usually, this increase links for isotropic antenna or dipole in free space half wave when 0° Height above sea level. Null reference (dBi) usually refers … Read more

Simple Basic behind Antenna Systems for RF

Simple Basic behind Antenna Systems for RF Any Antenna may be Omni antennas or Directional antenna. Omni antennas provide approximately the same amount of profit throughout the entire 360-degree horizontal pattern. Directional antenna, sometimes referred to as sector antennas have the maximum winnings in one direction from the backside, usually 15-25 DB below the maximum … Read more

What is Workload Modeling for LTE

What is Workload Modeling for LTE 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 … Read more
