How LTE Works On Your Android Phone
LTE relies on several complex technologies to deliver its performance benefits. Understanding these technologies can provide a deeper appreciation for how LTE works on your Android phone.
Orthogonal Frequency Division Multiplexing (OFDM)
OFDM is a modulation technique that divides a radio channel into multiple smaller sub-channels. This allows data to be transmitted in parallel, increasing data throughput. OFDM is more resistant to interference than traditional modulation techniques, which improves network reliability.
Multiple-Input Multiple-Output (MIMO)
MIMO uses multiple antennas at both the transmitter and receiver to improve data transmission efficiency. By sending and receiving data through multiple paths, MIMO can increase data rates and improve signal quality. Your Android phone and the cell tower both employ multiple antennas to leverage MIMO.
Carrier Aggregation
Carrier aggregation allows LTE networks to combine multiple frequency bands (carriers) into a single, wider channel. This increases the bandwidth available for data transmission, resulting in higher data speeds. For example, a network might combine two 10 MHz carriers to create a 20 MHz channel, effectively doubling the bandwidth.
Voice Over LTE (VoLTE)
VoLTE is a technology that allows voice calls to be made over the LTE network. Traditional voice calls used circuit-switched networks, while data was transmitted over packet-switched networks. VoLTE uses the packet-switched LTE network for both voice and data, which can improve call quality and reduce call setup times.
LTE Categories And Speeds
LTE is not a monolithic technology. Different LTE categories (also known as UE categories) define the maximum data speeds and capabilities supported by a device. These categories are standardized by the 3GPP (3rd Generation Partnership Project).
The higher the LTE category, the faster the theoretical maximum data speeds. Your Android phone’s LTE category determines the maximum speeds it can achieve on an LTE network.
Here’s a simplified overview of some common LTE categories:
- Category 4: Download speeds up to 150 Mbps, upload speeds up to 50 Mbps.
- Category 6: Download speeds up to 300 Mbps, upload speeds up to 50 Mbps.
- Category 9: Download speeds up to 450 Mbps, upload speeds up to 50 Mbps.
- Category 12: Download speeds up to 600 Mbps, upload speeds up to 100 Mbps.
- Category 16: Download speeds up to 1 Gbps (1000 Mbps), upload speeds up to 150 Mbps.
It’s important to note that these are theoretical maximum speeds. Actual speeds can vary depending on factors such as network congestion, signal strength, and distance from the cell tower.
