4g and 4g lte difference

Last updated on 

4G (Fourth Generation):

Definition: 4G is the fourth generation of mobile network technology. It succeeded 3G and offers faster data transmission speeds and more reliable connections than its predecessor.

Key Features of 4G:

  1. Speed: 4G networks aim to provide peak data rates of up to 100 Mbps for high mobility communication (like when you're moving in a car or train) and 1 Gbps for stationary users.
  2. Latency: The latency in 4G networks is expected to be around 50 milliseconds, which means the delay between sending and receiving data packets is minimal.
  3. Technology: 4G networks utilize Orthogonal Frequency Division Multiplexing (OFDM) for the downlink (from the tower to the device) and Single Carrier Frequency Division Multiple Access (SC-FDMA) for the uplink (from the device to the tower).

4G LTE (Long-Term Evolution):

Definition: LTE stands for Long-Term Evolution, and it's a standard for wireless broadband communication that allows for higher data speeds and improved network capacity. Essentially, LTE is a type of 4G technology.

Key Features of 4G LTE:

  1. Data Speeds: LTE enhances the speed and capacity of the 4G network. While 4G aims for specific speed benchmarks, LTE often surpasses these benchmarks, offering faster download and upload speeds in real-world scenarios.
  2. Efficiency: LTE employs advanced technologies like Multiple Input Multiple Output (MIMO) and Adaptive Modulation and Coding (AMC) to increase the efficiency of data transmission. These technologies allow for better spectral efficiency, meaning more data can be transmitted in the same amount of spectrum.
  3. Backward Compatibility: One of the advantages of LTE is its backward compatibility with older networks. This means that LTE-enabled devices can switch seamlessly between 2G, 3G, and 4G networks based on availability and signal strength.

Key Differences:

  1. Technical Foundation: While 4G is a broader term that defines the overall fourth-generation mobile network technology, LTE is a specific standard or technology within the 4G framework designed to enhance data speeds, efficiency, and overall performance.
  2. Speed and Efficiency: LTE typically offers faster data speeds and more efficient data transmission than generic 4G networks due to its advanced technologies and methodologies like MIMO and AMC.
  3. Evolution Path: LTE is a step in the evolutionary path of 4G technology. As the industry progresses, newer iterations and enhancements beyond LTE (like LTE Advanced and LTE Advanced Pro) continue to push the boundaries of what 4G networks can achieve in terms of speed, capacity, and reliability.

4G represents the broader generation of mobile network technology aimed at faster and more reliable communication, 4G LTE is a specific standard within that generation that focuses on maximizing data speeds and efficiency through advanced technologies and methodologies.
