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
Basic RF Propagation Models for LTE An RF propagation model is a mathematical formula used to characterize the radio is Wave transmitter at one end and the other end into the receiver propagation between It is usually a path RF frequency, distance, antenna heights of the terrain, Clutter and other conditions. It’s all in the … Read more
Fixed versus Mobile difference at RF Side Mobile (Portable) and fixed link between the proportion of the budget, there are four major Differences. The first difference between the fixed link will have a higher budget is usually Case-antenna mobile users have more. A second difference is For certain cases the loss of body assumed. The … Read more
How Subscriber types and Limiting RF Link for LTE Subscriber Equipment may take different form factors. It may resemble alert 3G phones, or maybe a CPE device, or a device connected to a USB dongle or USB port. RF different features, such as different transmission power levels, different Receive diversity schemes, different antenna patterns and … Read more
Margin sites intrusive noise levels due to an increase can be considered as If sites were spaced closer together than position using the same frequency The thermal noise floor. In other words, the system is interference limited as Opposed to limit noise. Often a site link budget maximum range is used to evaluate the process. … Read more
Google has reported that its first-quarter revenues jumped by nearly a third to US$14 billion, while profits rose to US$3.35 billion, compared to US$2.89 billion a year ago. Google said that its revenues from outside of the United States totaled $7.1 billion, representing 55% of total Google revenues in the first quarter of 2013, compared … Read more
