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 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 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 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 .
