What is BCCH frequency?

The frequency carrying the BCCH (Broadcast Control Channel) in a cell, is defined by the Absolute Radio Frequency Channel Number, ARFCN, with the parameter BCCHNO. The defined ARFCN must be unique within the cell.. Range: 128 to 251 (GSM 800). 1 to 124 (GSM 900, P-band). 512 to 885 (GSM 1800).

How do you calculate uplink and downlink frequency?

In cellular systems, the downlink and uplink channel qualities for a mobile station (MS) can be different for various reasons. Uplink frequency is the frequency at which, the first earth station is communicating with satellite. The Radio frequency is calculated as: Satellite – Transverter + Doppler shift.

What frequency does GSM use?

In North America, GSM operates on the primary mobile communication bands 850 MHz and 1900 MHz. In Canada, GSM-1900 is the primary band used in urban areas with 850 as a backup, and GSM-850 being the primary rural band. In the United States, regulatory requirements determine which area can use which band.

What is a full form of BCCH?

A broadcast control channel (BCCH) is a point to multipoint, unidirectional (downlink) channel used in the Um interface of the GSM cellular standard.

What is uplink and downlink frequency?

Uplink frequency is the frequency at which, the first earth station is communicating with satellite. The satellite transponder converts this signal into another frequency and sends it down to the second earth station. This frequency is called as Downlink frequency.

How is downlink calculated?

Down link C/No (dB Hz) It is the down link carrier to noise ratio. It can be calculated as follows. Solution: Down link C/No(dB Hz) = Satellite operating EIRP – Downlink path loss – Down link rain attenuation – Receiving antenna pointing loss + Receiver G/T +228.6.

How to calculate the antenna frequency?

Enter one (only one) value, the desired frequency or the antenna length in any length field. Click on Calculate and the opposite value will be displayed in feet and inches or frequency in megahertz (Mhz).

How do you calculate half wave dipole antenna length?

The Half-Wave Dipole Antenna. The most widely used formula to calculate the approximate overall length of wire required for a dipole is: 468 / frequency (MHz) = length of wire in feet. The antenna calculator above uses this formula as a starting point to calculate wire lengths for the dipole.

What is the antenna propagation calculator used for?

This can be useful for determining antenna ground plane requirements, antenna spacing requirements to prevent coupling in for multi-antenna systems, or other situations where the antenna’s wavelength is needed. This calculator assumes propagation in a free space, earth atmosphere environment.

How do you calculate the length of a loop antenna?

At HF frequencies, an inch is such a small part of a wavelength that it is a non issue. The basic formula for determining the length of a full-wave wire Loop antenna is: 1005 ÷ freq (mHz) = Length (feet).
