# What is LTE link budget?

## What is LTE link budget?

As the name suggests, a link budget is simply the accounting of all of the gains and losses from the transmitter, through the medium (free space, cable, waveguide, fiber, etc.) to the receiver in a telecommunication system. In this page, we will briefly discuss link budget calculations for LTE.

## How is LTE link budget calculated?

1. d(3d): Distance between Tx (eNodeB) and Rx (UE),m.
2. Receiver sensitivity (dBm) = Noise figure (dB) + Thermal noise (dBm) + SINR (dB)
3. Receiver sensitivity (dBm) = Noise figure (dB) + Thermal noise (dBm) + SINR (dB)
4. d'(bp) break point distance UMA, UMi, m.
5. d(bp) break point distance RMa,

What is link budget in telecom?

A link budget is an accounting of all of the power gains and losses that a communication signal experiences in a telecommunication system; from a transmitter, through a communication medium such as radio waves, cable, waveguide, or optical fiber, to the receiver.

What is link budget in 5G?

Link Budget depend on many factors: Main: frequency, bandwidth,Reception sensitivity (SINR) etc. For 5G network in your case you should to use smallest SINR=-6 dB ( Or sinr for your throughput KPI, maybe SINR 9….), smallest frequency, smallest bandwidth… with better configuration for throughtput.

### What is antenna gain in LTE?

Antenna gain indicates how strong a signal an antenna can send or receive in a specified direction. Gain is calculated by comparing the measured power transmitted or received by the antenna in a specific direction to the power transmitted or received by a hypothetical ideal antenna in the same situation.

### How is link margin calculated?

‣ The received power in an wireless link is determined by three factors: ‣ The difference between the minimum received signal level and the actual received power is called the link margin.

What is the purpose of link margin?

Then the link margin is applied which attempts to counteract the fluctuations of the signal and noise power to ensure reliable data delivery from transmitter to receiver. (Link margin is dictated by the link margin policy or requirements.)

What does EIRP stand for?

Equivalent isotropic radiated power, EIRP, is the total radiated power from a transmitter antenna times the numerical directivity of the antenna in the direction of the receiver, or the power delivered to the antenna times the antenna numerical gain.

## Which is the primary cost for degradation of error performance?

Which is the primary cost for degradation of error performance? Explanation: There are two primary causes for the degradation of error performance. They are loss in signal to noise ratio and the second is signal distortion caused by intersymbol interference.

## Does 5G use a lot of power?

On any network, your phone will use more battery if it is having a hard time finding a strong signal — with 5G’s current minimal coverage, this is far more likely to occur. The bottom line is that, under the right circumstances, using 5G can consume more battery power than 4G.

How can I calculate my LTE link budget?

You can calculate the Link budget (Signal level at receiver) and then compare it with Rx Reception sensitivity. Then you will understand Radio Channel Status (Pass or Fail) and Cell Radius. The calculation is based on the 3GPP 38.901 standard.

Which is the best 4G LTE budget calculator?

### What is the link budget for NB-IoT?

In technical terms, the coverage target of NB-IoT has a link budget of 164dB, whereas the current GPRS link budget is 144dB (TR 45.820), and LTE is 142.7 dB** (TR 36.888).

### How to calculate link budget for RX reception sensitivity?

You can calculate the Link budget (Signal level at receiver) and then compare it with Rx Reception sensitivity. Then you will understand Radio Channel Status (Pass or Fail) and Cell Radius. The calculation is based on the 3GPP 38.901standard.
