Why not to use VoIP?

While Voice over Internet Protocol (VoIP) has become a widely adopted technology for voice communication, there are situations and considerations where using VoIP may not be the most suitable option. It’s important to recognize that the decision to use or not use VoIP depends on specific requirements, preferences, and constraints. Let’s explore in detail some … Read more

Why multiple antennas are used in MIMO system?

Multiple Input Multiple Output (MIMO) is a wireless communication technology that utilizes multiple antennas at both the transmitter and receiver ends of a communication system. The use of multiple antennas in a MIMO system brings about significant advantages, enhancing system performance and reliability. Let’s delve into the detailed reasons why multiple antennas are used in … Read more

Why LTE uses OFDMA for downlink and SC-FDMA for uplink?

LTE (Long-Term Evolution) utilizes a combination of multiple access schemes for its downlink (DL) and uplink (UL) transmissions. Specifically, LTE employs OFDMA (Orthogonal Frequency Division Multiple Access) for the downlink and SC-FDMA (Single-Carrier Frequency Division Multiple Access) for the uplink. This strategic selection is driven by the unique requirements and characteristics of each direction of … Read more

Why is RSRQ poor?

A poor RSRQ (Reference Signal Received Quality) in LTE (Long-Term Evolution) networks indicates suboptimal conditions for signal reception, which can impact the overall performance and quality of the network. Several factors contribute to a poor RSRQ, and understanding these issues is crucial for network operators to identify and address issues that may affect user experience. … Read more

Why is RSRQ important?

RSRQ, or Reference Signal Received Quality, is an essential parameter in LTE (Long-Term Evolution) networks, playing a crucial role in evaluating the quality of the received signals. RSRQ is particularly important for optimizing network performance, ensuring reliable communication, and maintaining a high-quality user experience. Let’s explore in detail why RSRQ is important in LTE networks: … Read more

Why LTE is called flat architecture?

LTE (Long-Term Evolution) is referred to as having a “flat architecture” due to its streamlined and simplified network structure compared to previous generations of wireless networks. The term “flat” signifies a departure from the more hierarchical and complex architectures of previous generations like 2G and 3G. Let’s delve into the characteristics that make LTE a … Read more

Why is it called LTE and not 4G?

The term “LTE” stands for “Long-Term Evolution,” and its nomenclature reflects a strategic decision made by the telecommunications industry to signify a significant leap forward in wireless communication technology. The use of “LTE” instead of “4G” is rooted in the desire to convey a focus on continuous improvement, a commitment to long-term evolution, and a … Read more

Why is LTE called Long Term Evolution?

The name “LTE,” standing for “Long-Term Evolution,” reflects a strategic choice made by the telecommunications industry to emphasize a vision of continuous advancement and evolution in wireless communication technology. This nomenclature goes beyond mere generational labeling, indicating a commitment to long-term viability, adaptability, and sustained progress. Let’s explore in detail why LTE is called Long-Term … Read more

Why is GTP used in LTE?

The GTP (GPRS Tunneling Protocol) is a crucial protocol used in LTE (Long-Term Evolution) networks to facilitate the efficient transfer of user data and control information between different elements of the Evolved Packet System (EPS). GTP plays a fundamental role in establishing and managing tunnels, enabling the encapsulation and transport of user data across the … Read more

Why does LTE have hard handover?

LTE (Long-Term Evolution) primarily employs soft handover as the standard handover mechanism. Soft handover is a process where a mobile device is simultaneously connected to multiple base stations (eNodeBs) during a handover. This allows for a seamless transition and continuous communication, enhancing network reliability and coverage. However, in certain scenarios, LTE may use hard handover, … Read more
