Rain fade. Rain fade refers primarily to the absorption of a microwave radio frequency (RF) signal by atmospheric rain, snow, or ice, and losses which are especially prevalent at frequencies above 11 GHz. It also refers to the degradation of a signal caused by the electromagnetic interference of the leading edge of a storm front.
The downlink satellite signal, quite weak after traveling the great distance (see path loss), is collected with a parabolic receiving dish, which reflects the weak signal to the dish's focal point. [11] Mounted on brackets at the dish's focal point is a device called a feedhorn or collector. [12]
In February 2023, Dish Network suffered a major ransomware attack which resulted in internal outages, loss of service at subsidiary companies such as Boost Mobile, and data theft. [66] The company had to retain outside experts to resolve the issue, and the news caused a slide in the company's share price to a 14-year-low.
The front page of Dish's website currently displays a banner thanking customers for their patience, stating, "We are experiencing a system Dish Network's internal system has days-long outage Skip ...
Sun outage. A Sun outage, Sun transit, or Sun fade is an interruption in or distortion of geostationary satellite signals caused by interference (background noise) of the Sun when it falls directly behind a satellite which an Earth station is trying to receive data from or transmit data to. It usually occurs briefly to such satellites twice per ...
Criticism of Dish Network. Dish Network has been the subject of a number of criticisms relating to management of advertising, disclosure of fees, telemarketing, employee rights and programming disputes; a number of which resulted in lawsuits. In the early 2000s, Dish Network received criticism regarding controversial technology and carriage ...
Link budget. A link budget is an accounting of all of the power gains and losses that a communication signal experiences in a telecommunication system; from a transmitter, through a communication medium such as radio waves, cable, waveguide, or optical fiber, to the receiver. It is an equation giving the received power from the transmitter ...
In telecommunications, return loss is a measure in relative terms of the power of the signal reflected by a discontinuity in a transmission line or optical fiber. This discontinuity can be caused by a mismatch between the termination or load connected to the line and the characteristic impedance of the line. It is usually expressed as a ratio ...
