The Benefits of 60GHz PTP/PTMP Over 5GHz

Background of Wireless Networking

Point-to-Point (PTP) and Point-to-Multipoint (PTMP) links are popular for connecting different locations with high-speed, reliable communication over distances up to several kilometres. Traditionally, 5GHz PTP/PTMP links have been widely used due to their reliable performance and broad compatibility. However, the invention of 60GHz technology is changing this field - offering significant improvements in speed, capacity, and reducing interference. Here we take a look at the key benefits of 60GHz over 5GHz, explaining why it is becoming the preferred choice for many network installers and businesses in the UK and overseas.

Higher Throughput and Speed: One of the greatest advantages of 60GHz PTP/PTMP is its ability to provide much higher data rates compared to 5GHz. While 5GHz can offer speeds up to several hundred Mbps, 60GHz links can deliver multi-gigabit throughput, often exceeding 1Gbps and even reaching up to 10Gbps. This increased speed is crucial for applications with high bandwidth requirements such as HD video streaming, large file transfers, and high-speed internet access.

Greater Spectrum Availability: The 60GHz band offers a significantly larger spectrum compared to the 5GHz band. 60GHz PTP links have access to multiple wide channels, allowing for greater data throughput and reducing the likelihood of congestion/interference. In contrast, the 5GHz band is narrower, with fewer non-overlapping channels. This can lead to more interference and limited bandwidth in dense environments.

Reduced Interference: Interference is a common challenge in the 5GHz band, particularly in urban and densely populated areas where many devices and networks operate on the same frequencies. The 60GHz band, however, benefits from reduced interference due to its high frequency and shorter wavelength. The narrow beamwidth of 60GHz signals results in less signal scattering and makes them more directional, making it less prone to interference from other wireless networks and devices.

Improved Security: The narrow beamwidth and high directionality of 60GHz signals not only reduces interference but also enhances security. The focused beams are harder to intercept compared to the broader coverage of 5GHz signals. This increased security is particularly valuable for applications requiring secure communication links, such as financial transactions, government communications, and private enterprise networks.

Weather Resilience: While 60GHz signals are more susceptible to oxygen absorption, weakening the signals over distance, modern 60GHz PTP/PTMP devices are designed to mitigate these effects through advanced modulation and error correction techniques. For short distance links, the impact of weather conditions such as rain or fog is minimal. In contrast, 5GHz signals can be affected by heavy rain and other environmental factors, which can degrade performance over longer distances.

Unlicensed Spectrum and Ease of Deployment: Both the 5GHz and 60GHz bands are typically unlicensed, making them accessible for quick and cost effective deployment. However, the 60GHz band offers the advantage of less regulatory congestion and fewer restrictions, making it easier to implement high capacity links without extensive licensing procedures. This can significantly speed up the deployment process and reduce operational costs.

Future-Proofing: Investing in 60GHz PTP/PTMP technology is a forward thinking decision, as it supports the growing demand for higher bandwidth and the increase of data intensive applications. As more devices and services require faster and more reliable connections, 60GHz links provide a scalable solution that can accommodate future network growth and evolving technological needs.

Do I move to 60GHz or stick with 5GHz?

While 5GHz devices have served wireless networks well up until now, the benefits of 60GHz technology can't be ignored in 2024. With all the above benefits taken into consideration, 60GHz PTP/PTMP is likely to become the new standard for high performance wireless communication. As consumers look to meet increasing demand for bandwidth and reliable connectivity, 60GHz PTP/PTMP offers a reliable and innovative solution that is transforming wireless networking and will provide a great return on investment.
