A. The amount of bandwidth allotted to each channel in a communications system that transmits multiple frequencies such as fiber optics . It is measured as the spacing between center frequencies (or wavelengths) of adjacent channels.
Read moreWhat is channel spacing in frequency?
Channel spacing, also known as bandwidth, is a term used in radio frequency planning. It describes the frequency difference between adjacent allocations in a frequency plan .

FDD -LTE : Uzak ve geniş alanlarda kullanılacak ve bağlantı kurulurken fazla paket kaybı olmayacak, bunun yanı sıra veri indirme ve yükleme işleminin aynı zamanda yapılırken internet hızında diğer LTE standarta göre biraz daha yavaş olacak olan, stabil çalışacağı söylenen bir 4G sistemidir.29 Kas 2014
Read moreLTE TDD & LTE FDD nedir?
LTE -FDD ile LTE -TDD arasındaki farkı basitçe – TeknoSeyir. FDD iki ayrı frekans ile uplaod ve downloadı gerçekleştırıyor. TDD ise aynı frekansı yarı yarıya kullanarak DL ve ULı gerçekleştiriyor.
Read moreHow OFDM is used in LTE?
LTE uses a pre-coded version of OFDM called Single Carrier Frequency Division Multiple Access (SC-FDMA) in the uplink . This is to compensate for a drawback with normal OFDM, which has a very high Peak to Average Power Ratio (PAPR).
Read moreWhat is OFDM symbol in LTE?
One of the key elements of LTE is the use of OFDM (Orthogonal Frequency Division Multiplex ) as the signal bearer, as well as OFDM’s associated access schemes, OFDMA (Orthogonal Frequency Division Multiple Access) and SC-FDMA (Single Carrier Frequency Division Multiple Access).
Read moreWhat is OFDM and SC FDMA in LTE?
LTE is based on Orthogonal Frequency Division Multiplexing (OFDM) with cyclic prefix (CP) in the downlink, and on Single-Carrier Frequency Division Multiple Access (SC-FDMA) with cyclic prefix in the uplink. It supports both FDD and TDD duplex modes for transmission on paired and unpaired spectrum.
