What is the downlink peak rate designed by LTE?
3 Gbps
Long-term evolution (LTE) is the most recent 3GPP radio access technology and provides high data rates for end users (peak data rate 3 Gbps in the downlink with the latest specification releases, also referred to as LTE-Advanced), low access latency, and good spectral efficiency.
What is a peak data rate?
Peak data rate is the fastest data transfer rate for a device, typically available in short bursts during transfer activity, and not sustainable for long periods of time.
What is the peak rate and mobility requirement of downlink and uplink of LTE and LTE Advanced?
3.2 LTE-Advanced Requirements Peak data rate of 1 Gbps for downlink (DL) and 500 Mbps for uplink (UL).
What is the data rate of up link in LTE?
LTE-M in the half duplex mode that is currently available can reach around 300 kbps in downlink and 380 kbps in uplink. On the field, average data rates of 100 to 150 kbps is reached in both directions with lower figures of a few Kbps when extended coverage features are in use.
What is uplink and downlink speed?
Uplink speed is the speed at which data can be transferred from the router to your ISP. ISPs often specify speed as a downlink/uplink pair; for example, 1.5Mbps/284kbps. For this example, you would enter “284”. Alternatively you can test your uplink speed with a service such as www.dslreports.com.
How is peak data rate calculated in LTE?
The maximum data rate depends on channel bandwidth. As LTE uses different channel bandwidths both for FDD and TDD. Let’s take the example for LTE using FDD, where channel bandwidth can be 5 MHz, 10 MHz and 20 MHz. So the data rate is 1800 / 71.4 = 25.2 Mbps.
How is LTE downlink throughput calculated?
If modulation used is 64 QAM (6 bits per symbol) then throughput will be 16.8×6=100.8Mbps for a single antenna port. If we consider a 2×2 MIMO system then this throughput will be double i.e. 100.8×2= 201.6 Mbps and with 4×4 MIMO system then throughput is about 100.8×4= 403.2 Mbps.
How is peak data rate calculated?
Uplink Throughput calculation:
- Peak Throughput= Maximum Transport Block / Transmission Time Interval = 1000 bits /4 ms.
- Throughput (With out NPRACH) 680 bits/ NPDCCH duration (1 ms) + offset (8 ms) + NPUSCH duration (4ms) + offset (3ms)
- Throughput (With NPRACH) : Assuming NPRACH is a 10\% overhead.
Why is LTE needed?
Assuming you live in an area with decent LTE coverage, you should immediately notice enhanced overall network and device performance when connected to LTE. Faster data speeds mean your device can communicate with the Web and your various online services more quickly and efficiently.
What is uplink data rate?
Data rate = Number of bytes transferred/Total time taken(second). It is specified in Mbps or Mega bits per second.
How is downlink calculated?
Down link C/No (dB Hz) It is the down link carrier to noise ratio. It can be calculated as follows. Solution: Down link C/No(dB Hz) = Satellite operating EIRP – Downlink path loss – Down link rain attenuation – Receiving antenna pointing loss + Receiver G/T +228.6.
