TD-LTE Solar Base Station EMS Parameters

4 FAQs about [TD-LTE Solar Base Station EMS Parameters]

What is the difference between a base station analyzer and LTE EVM?

Overall, the LTE EVM specification requires special attention to the higher bandwidth and smaller duplex distances. For the same reasons, the TX out-of-band noise is more dificult to achieve in LTE. The Base Station Analyzer satisfies the requirement of 3GPP for modulation accuracy measurement for LTE signals.

What SNR is required to demodulate a 5 MHz LTE signal?

According to Table 2-3: a minimum base band SNR of 11.3dB is required to demodulate this LTE signal. The following example describes a dynamic range test case for a 5 MHz LTE signal. According to the desired LTE signal will be raised to -70.2dBm. An in-channel interference AWGN signal will be introduced at a power level of -82.5dBm.

How many cellular base stations are solar powered?

PV power is utilized in remote cellula r base statio ns, in de veloping countries the base stations often of f-grid and depend on their power sources. In developing countr ies there are over 230,000 cellular base stations will be wind-powered or PV -powered b y 2014 (Pande, 2009; Akkucuk, 2016). by 2014 (Bell & Leabman, 2019).

What factors affect the unwanted emission characteristic of LTE transmitters?

spectrum emission mask (SEM). It is known that the following factors afect the unwanted emission characteristic of transmitters. intermodulation distortion (IMD)—LTE downlink signals are composed by a few tenths to thousands of subcarriers allocated with 15 kHz frequency spacing.
