4G LTE Essentials
LTE was designed with remarkable deployment flexibility by supporting six distinct channel bandwidth options. Operators can choose from 1.4, 3, 5, 10, 15, or 20 MHz depending on how much spectrum they hold in a given band. Each bandwidth maps directly to a specific number of resource blocks available for scheduling. A 1.4 MHz carrier provides just 6 resource blocks suitable for narrowband IoT applications, while the full 20 MHz carrier delivers 100 resource blocks capable of peak throughputs exceeding 150 Mbps with two-layer MIMO. Most commercial LTE networks today deploy 10 or 20 MHz…
Try these first, even if you're not sure. Guessing primes your brain.
A carrier doubles from 10 to 20 MHz. What happens to peak throughput?
An operator holds 15 MHz and 10 MHz on two bands. Best use?
Why keep a narrow 1.4 MHz option in LTE?
