Erlangs calculation depend upon Traffic channel in GSM?

Erlangs calculation in GSM is based on the number of traffic channels available for carrying voice or data traffic in the network. It helps in determining the traffic load on a particular cell or network and aids in capacity planning by estimating the number of required channels to handle the traffic. By using Erlangs, operators can optimize their network resources and ensure efficient utilization of available capacity.


Why does GSM use separate channels for Uplink and Downlink?

So that they can both be used at the same time (i.e. full duplex) without interference.

Gsm 900 vs gsm 1800?

GSM-900 and GSM-1800 are used in most parts of the world: Europe, Middle East, Africa, Australia and most of Asia. In South and Central America the following countries use the following: : :* Costa Rica - GSM-1800 :* Brazil - GSM-850, 900 and 1800 :* Guatemala - GSM-850, GSM-900 and 1900 :* El Salvador - GSM-850, GSM-900 and 1900 GSM-900 uses 890-915 MHz to send information from the mobile station to the base station (uplink) and 935-960 MHz for the other direction (downlink), providing 124 RF channels (channel numbers 1 to 124) spaced at 200 kHz. Duplex spacing of 45 MHz is used. Guard bands 100 kHz wide are placed at either end of the range of frequencies[1]. : In some countries the GSM-900 band has been extended to cover a larger frequency range. This 'extended GSM', E-GSM, uses 880-915 MHz (uplink) and 925-960 MHz (downlink), adding 50 channels (channel numbers 975 to 1023 and 0) to the original GSM-900 band. The GSM specifications also describe 'railways GSM', GSM-R, which uses 876-915 MHz (uplink) and 921-960 MHz (downlink). Channel numbers 955 to 1023. GSM-R provides additional channels and specialized services for use by railway personnel. : All these variants are included in the GSM-900 specification. GSM-1800 uses 1710-1785 MHz to send information from the mobile station to the base tranceiver station (uplink) and 1805-1880 MHz for the other direction (downlink), providing 374 channels (channel numbers 512 to 885). Duplex spacing is 95 MHz. : GSM-1800 is also called DCS (Digital Cellular Service) in the United Kingdom, while being called PCS in Hong Kong[2] (not to mix up with GSM-1900 which is commonly called PCS in the rest of the world.)

Difference between a gsm and a conventional network provider?

The first data services in GSM networks were circuit-switched, asynchronous ... data can be exchanged with all conventional receivers, provided that the ... data packets, and transmitted through one or more available channels between the mobile ... Therefore, the GSM and UMTS standard offer two different transmission.


What is HSCSD?

High Speed Circuit Switched Data is an enhancement to the GSM mobile communications system that enables up to four 14.4 Kbps channels to be combined to provide 57.6 Kbps data transfer. Part of GSM Phase 2, HSCSD is suited for videoconferencing and multimedia transmission.


How does number of protein channels affect diffusion in a cell.?

The number of protein channels in a cell directly affects the rate of diffusion of molecules across the cell membrane. A higher number of protein channels allow for more molecules to pass through, leading to faster diffusion. Conversely, a lower number of protein channels may result in slower diffusion rates.


If gsm 900 is superior than gsm 1800 than why do 3G uses 2100mhz-?

Scientifically it is proved that The higher you go in the GSM number, the lesser the wavelength. Therefore GSM900 Is preferred than Gsm1800. But 3G uses 2100 what is the reason?
