Richard Jhon 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
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 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 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
Although only 5.6% of sales of smartphones in the first quarter of 2013, Windows showed continued growth, gaining 1.9% compared to the same period last year, according to data released today by Kantar hundred Worldpanel Comtech. Almost half (49.3%) Smartphone sales, remains the best selling Android operating system, but saw only a slight increase compared … Read more
Although Fitch Ratings has not released the official rating on Apple; He said today that such a rating is likely to fall in the same category of “high” rating–and would not be good enough to reach the status of “AA”. Discussion about debt rating was prompted by comments from Apple that she may seek to … Read more
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 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 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
Capacity and MPR and CINR Distributions for LTE Throughput or bandwidth that LTE was taken for the physical layer for the MCS under the pick or sustainable conditions. Throughput, individual users might be depends both on the MCS allocated (a function of characteristics and conditions of the user channel) and the requirements of other users … Read more
