The lower frequencies, down near the 700MHz band , give better signal penetration, offering stronger coverage in buildings, carparks, elevators and the like. The higher frequencies up toward the 2,600MHz band have a higher capacity for data.
Read moreWhat spectrum is LTE?
LTE frequencies exist in a spectrum from frequencies as low as 700 MHz right up to high frequencies of 2600 MHz . To understand the role of different frequencies across the spectrum, it can help to consider the extreme examples – the very highest and very lowest LTE frequencies available in North America.
Read moreHow many subframes are there in an LTE frame?
The basic type 1 LTE frame has an overall length of 10 ms. This is then divided into a total of 20 individual slots. LTE Subframes then consist of two slots – in other words there are ten LTE subframes within a frame.
Read moreWhy is the LTE frame 10ms?
So a LTE radio frame consists of 10 subframes (i.e. total 1 ms) in time domain & 72 subcarriers (i.e. total 1080 Khz) in freq domain. Why 15kHz? It is because UMTS and LTE have the same clock timing !
Read moreHow many symbols are in a LTE frame?
Each LTE symbol will be roughly of 67 microseconds and there will be 7 symbols per slot, 14 symbols per subframe and 140 symbols per radio frame . The number & duration of symbols will change, if the system is configured to extended cyclic prefix type.
Read moreWhat is frame length in LTE?
LTE supports two frame lengths, 5 ms and 10 ms . Each 10 ms interval contains 10 subframes, which are labeled in the Table as D for downlink transmission, U for uplink transmission, and S for special subframe. The special subframe contains the turnaround time between downlink and uplink transmissions.
Read moreWhat is the difference between Earfcn and frequency?
Understanding LTE Carrier Frequency and EARFCN EARFCN uniquely identify the LTE band and carrier frequency. For example Band-1 and Band-4 can have same Rx frequency 2110-2170 MHz, but their EARFCN are different. EARFCN is independent of channel bandwidth .
