Technical FAQs 4

What is FDMA & TDMA?

Use a unique frequency: FDMA (Frequency Division Multiple Access). Use a unique time slot: TDMA (Time Division Multiple Access). Use a unique code: CDMA (Code Division Multiple Access). 6. If the resource (frequency, time, code) is allocated in advance, it is called pre-assigned or fixed-assignment multiple access (FAMA).

What is FDMA in satellite communication?

You might find these chapters and articles relevant to this topic. FDMA is the most common MA technique for satellite communication systems. Especially, a single channel per carrier (SCPC), in which each carrier bears one voice or data channel, has been used in most operating satellite communication systems because of its simple implementation.

What is frequency division multiple access (FDMA)?

H.Revenue to operator is maximized. Frequency Division Multiple Access, or FDMA, is a channel access method used in multiple-access protocols as a channelization protocol. FDMA gives users an individual allocation of one or several frequency bands. It is particularly common-place in satellite communication.

How many channels can a base station handle?

Each base station can accommodate 123 frequency bands, each 200 kHz wide, through Frequency Division Multiple Access (FDMA). Each frequency band has the capacity to handle 8 speech channels, which are multiplexed in time resulting in Time Division Multiple Access (TDMA). This results in 984 channels.
