What is LTE SINR range?
SINR/SNR – The signal-to-noise ratio of the given signal. RSRP – The average power received from a single Reference signal, and Its typical range is around -44dbm (good) to -140dbm(bad). RSRQ – Indicates quality of the received signal, and its range is typically -19.5dB(bad) to -3dB (good).
What is a good Sinr for LTE?
4G (LTE)
| SINR | Signal strength |
|---|---|
| >= 20 dB | Excellent |
| 13 dB to 20 dB | Good |
| 0 dB to 13 dB | Fair to poor |
| <= 0 dB | No signal |
What can interfere with a 4G signal?
Hills, mountains, bluffs, heavy vegetation, and even weather can kill your cell signal. Glass/windows. When cell phone users lose signal or drop a call inside of a building, it can seem instinctive to move near a window.
What is LTE Sinr signal?
SINR (Signal to Interference & Noise Ratio) measures signal quality: the strength of the wanted signal compared to the unwanted interference and noise.
What causes uplink interference on an LTE network?
LTE uplink interference happens when there’s too much overlap in the DL (downlink) coverage. In FDD LTE deployment the uplink is a shared frequency resource utilized by each base station and the UE. Based on the fact this resource is shared, you can have multiple UEs sharing the same frequency but talking to two different towers.
What is the name of the uplink control channel?
The physical uplink control channel, also called PUCCH, carries the control channel information which can be (but is not limited to) acknowledgements of downlink data. The specifics of what can be encoded in the PUCCH are defined by many different formats.
Can a UE transmit more than 23 dBm?
As we know based on UE class category. It cannot transmit more than its maximum UE power which is commonly 23 dBm for most LTE UEs in the Uplink. The objective of the eNOdeB is that UE should transmit only enough power in the uplink in a range which is the minimum required amount. Neither more, nor less than that.
Why is there so much noise on my uplink?
This is also sometime referred to as uplink noise rise and occurs when there are lots of phones communicating on the uplink and each of their energies contributes to the rise in overall noise floor on the channel. Each user is consuming a piece of this resource even if very little or no data is being transmitted.
