4G/LTE cellular phone
Advanced70 min
Understand how a phone attaches to a cell: OFDM modulation, mobility, echoes and useful throughput.
What you get
A simulated cellular link where throughput drops as you move away or as echoes increase.
Parts (simulated)
- Built-in RF/SDR lab
- Multipath channel model
- Virtual measurement instruments
Nothing to buy: every component here is simulated in the browser.
Project steps
- 01Configure the cell's band and channel width.
- 02Transmit with multi-carrier modulation and watch the spectrum.
- 03Add mobility and multipath.
- 04Measure the impact on error rate and useful throughput.
- 05Compare with the Wi-Fi and satellite links.
What you learn
- Multi-carrier and channel width
- Multipath and fading
- Throughput / range / robustness trade-offs
