Why do we allow LTE in unlicensed spectrum if cellular network operators has already have exclusive access to licensed spectrum? It seems like they also want to devour our use of Wi-Fi by interfering with us users of unlicensed spectrum.

The coexistence of LTE (Long-Term Evolution) in unlicensed spectrum, particularly through technologies like LTE-U (LTE-Unlicensed) and LAA (Licensed Assisted Access), has been a subject of debate and scrutiny. Here are some key points to consider:

  1. Spectrum Efficiency: Cellular network operators typically have exclusive access to licensed spectrum, which they use for their primary cellular services. However, licensed spectrum is a limited resource, and with the increasing demand for mobile data, operators are constantly exploring ways to enhance their network capacity. Utilizing unlicensed spectrum in conjunction with licensed bands can improve overall spectrum efficiency and help meet growing data demands.
  2. Enhanced Network Performance: By deploying LTE in unlicensed spectrum, cellular operators can offload some of the data traffic from their licensed bands to unlicensed bands. This offloading can help alleviate congestion on the licensed spectrum and enhance the network performance for cellular users.
  3. Coexistence Challenges: Unlicensed spectrum is traditionally used for technologies like Wi-Fi, Bluetooth, and other wireless applications. The introduction of LTE-U/LAA in unlicensed bands has raised concerns about potential interference with existing Wi-Fi networks. To mitigate these concerns, regulatory bodies and industry organizations have established coexistence mechanisms, such as Listen Before Talk (LBT) protocols, to ensure fair sharing of the unlicensed spectrum.
  4. Competitive Landscape: The introduction of LTE in unlicensed spectrum also has commercial implications. Cellular operators may aim to extend their service coverage and provide a more seamless user experience by leveraging both licensed and unlicensed spectrum. This can create competition between cellular operators and traditional Wi-Fi providers, leading to debates about fair access to unlicensed spectrum.

It’s important to note that regulatory bodies play a crucial role in ensuring fair and efficient spectrum allocation. They establish rules and guidelines for spectrum usage, taking into account the interests of various stakeholders, including cellular network operators and users of unlicensed spectrum. The objective is to strike a balance between promoting innovation, encouraging healthy competition, and safeguarding the quality of existing wireless services.

LTE-U is extremely unfair, they have their licensed spectrum and can use that exclusively, then they also want us people who use Wi-Fi to get our frequency?

I understand your concern regarding LTE-U and its impact on Wi-Fi users. The coexistence of LTE-U and Wi-Fi in unlicensed spectrum has indeed raised questions about fairness and potential interference. Here are a few points to consider:

  1. Regulatory Oversight: Regulatory bodies, such as the Federal Communications Commission (FCC) in the United States, are responsible for managing spectrum allocation and ensuring fair usage. They establish rules and technical requirements to prevent harmful interference and maintain a balance between different technologies sharing the unlicensed spectrum.
  2. Coexistence Mechanisms: To address interference concerns, LTE-U and similar technologies are designed to incorporate coexistence mechanisms, such as Listen Before Talk (LBT) protocols. These protocols ensure that LTE-U devices check the spectrum for existing Wi-Fi signals and only transmit when the spectrum is clear. The aim is to enable fair sharing of the unlicensed spectrum between Wi-Fi and LTE-U technologies.
  3. Enhanced Spectrum Efficiency: The deployment of LTE-U in unlicensed spectrum is driven by the need to improve overall spectrum efficiency and meet the growing demand for mobile data. By utilizing unlicensed bands, cellular operators can offload some of the data traffic from their licensed spectrum, which can help alleviate congestion and enhance network performance for their users.
  4. Evolving Wireless Landscape: The wireless landscape is continuously evolving, and new technologies are being introduced to meet the demand for connectivity. This evolution often involves finding ways to maximize spectrum utilization. While LTE-U may have initially raised concerns, ongoing efforts by regulatory bodies and industry organizations aim to ensure fair coexistence between Wi-Fi and cellular technologies in the unlicensed spectrum.

It’s important for regulatory bodies to strike a balance that benefits both Wi-Fi users and cellular network operators. Through regulations and coexistence mechanisms, the goal is to ensure that different technologies can effectively share the unlicensed spectrum while minimizing interference and maintaining a fair environment for all users.

If our cellular network operators started using LTE-U in our area, I will definitely buy my own LTE equipment and use their licensed frequency as Wi-Fi so that they will feel how it is to get interference.

I understand your frustration, but it’s important to approach the situation with a fair and constructive mindset. Interfering with licensed frequencies or engaging in activities that violate regulations can have legal consequences. Instead, consider these alternatives:

  1. Engage in Public Discourse: Express your concerns to regulatory bodies, local government representatives, and consumer advocacy organizations. Participating in public discussions can help raise awareness about the potential issues associated with LTE-U and influence decision-making processes.
  2. Collaborate with Wi-Fi Associations: Support and engage with organizations that represent Wi-Fi users’ interests. They can advocate for fair spectrum allocation and work towards ensuring that the needs of Wi-Fi users are considered in the regulatory decision-making processes.
  3. Optimize Your Wi-Fi Setup: Enhance your Wi-Fi network’s performance by using the latest Wi-Fi standards, optimizing router placement, and minimizing interference from other devices. These measures can help mitigate potential impacts from LTE-U deployments in your area.
  4. Explore Wi-Fi Alternatives: Keep an eye on emerging Wi-Fi technologies and advancements, such as Wi-Fi 6 and Wi-Fi 6E, which utilize additional frequency bands. These technologies can provide improved performance and less susceptibility to interference.

Remember, it’s essential to promote constructive dialogue, follow legal guidelines, and work towards finding solutions that benefit all stakeholders involved.
