Industry Leading VSWR Performance

In wireless networks, signal quality directly impacts data transmission speeds. A better signal (thanks to low VSWR) often means higher data throughput. This is because a stronger and clearer signal is less prone to errors and retransmissions, which can slow down internet speeds. End-users will experience faster and more consistent internet speeds, which is particularly important for bandwidth-intensive activities like streaming, gaming, and video conferencing.
For subscribers, an efficiently functioning WISP network with low VSWR means better signal strength and quality, leading to improved internet speeds and reliability. This is essential for customer satisfaction and retention in the competitive ISP market.
Low VSWR contributes to overall network reliability. When the antenna system efficiently transmits and receives signals, it reduces the likelihood of connectivity issues, dropped connections, and inconsistent performance. This reliability is crucial for end-users, as it ensures a more stable and dependable internet connection, which is essential for both residential and business customers.
VSWR is a measure of how efficiently RF power is transmitted from the radio into the antenna and, subsequently, into the air. A VSWR of less than 1.6 indicates that a significant majority of the power is being effectively radiated by the antenna. This efficiency is crucial for WISPs, as it ensures that the power supplied to the antenna is used effectively for transmitting signals, rather than being reflected back to the source.
With antennas that have a low VSWR, field technicians find it easier to align and set up the equipment. Low VSWR antennas are more forgiving in terms of alignment, meaning they can maintain good performance even if they are not perfectly aligned with the base station. This reduces installation time and complexity, allowing technicians to successfully complete installations more quickly and with fewer challenges.
Lower VSWR values imply lower signal reflections. High reflections (indicated by high VSWR) can cause signal losses, reducing the effective range and quality of the wireless service. For WISPs, who may be serving customers over considerable distances, minimizing these losses is key to maintaining a strong and reliable signal.
With antennas that have a low VSWR, field technicians find it easier to align and set up the equipment. Low VSWR antennas are more forgiving in terms of alignment, meaning they can maintain good performance even if they are not perfectly aligned with the base station. This reduces installation time and complexity, allowing technicians to successfully complete installations more quickly and with fewer challenges.
High VSWR levels can damage radio equipment over time. When a significant amount of power is reflected back towards the transmitter, it can cause overheating and stress on the transmitter's components. Keeping VSWR low helps in protecting the longevity and performance of radios.
Installation standards for FWA often include specific criteria for signal strength and quality. Antennas with a low VSWR perform more efficiently, making it easier for technicians to meet or exceed these standards. This ensures a higher likelihood of successful installation on the first attempt, reducing the need for return visits and adjustments which are costly and cause customer dissatisfaction.
A good VSWR, like 1.6 or lower, usually indicates that the antenna system (including cables, connectors, and the antenna itself) is well-matched and functioning correctly. This means more consistent and reliable performance, which is vital for WISPs to provide stable internet connectivity to their customers.
Efficiently functioning antenna systems with low VSWR are less prone to technical issues, which can reduce the need for maintenance and customer support. This not only improves the user experience but also can lead to cost savings for the ISP in terms of reduced labor and operational costs associated with troubleshooting and repairing network issues.
With a low VSWR, FWA antennas can effectively cover a larger area. This is because the transmitted power is used more efficiently, allowing signals to reach farther distances without significant loss. This is particularly important for FWA installations in rural or remote areas where distances between the transmission point and end users can be considerable.
Low VSWR antennas tend to perform consistently across different environmental conditions and terrains. This adaptability makes it easier for technicians to install in a variety of locations, from urban areas to remote and rural settings, while still achieving the desired performance levels.
