60Ghz Gigabit PTP/PTMP for WISP LastMile/Backhaul/CCTV-Link/Gigabit Building to Building Link Solution
Why Using 60GHz?
License-free 60GHz radios have unique characteristics that make them significantly different from traditional 2.4GHz or 5GHz license-free radios and from licensed-band millimeter-wave radios. These characteristics give 60GHz radios operational advantages not found in other wireless systems.
The FCC allocated an unprecedented 7GHz of un-channelized spectrum for license-free operation between 57-64GHz. This compares to less than 0.5GHz of spectrum allocated between 2-6GHz for WiFi and other license-free applications. For the first time, sufficient spectrum has been allocated to make possible multi-gigabit Radio Frequency (RF) links.
Narrow Beam Antennas
The very narrow beam associated with 60GHz radios enables multiple 60GHz radios to be installed on the same rooftop or mast, even if they are all operating at the same transmit and receive frequencies. Co-located radios operating in the same transmit and receive frequency ranges can easily be isolated from one another based on small lateral or angular separations and the use of cross-polarized antennas.
Oxygen attenuates 60GHz signals, a property that is unique to the 60GHz spectrum. While this limits the distances that 60GHz links can cover max2.5km, it also offers interference and security advantages when compared to other wireless technologies. Small beam sizes coupled with oxygen absorption makes these links highly immune to interference from other 60GHz radios. Another link in the immediate vicinity will not interfere if its path is just slightly different from that of the first link, while oxygen absorption ensures that the signal does not extend far beyond the intended target, even with radios along the exact same trajectory.
- 60GHz Radios: License-free 60GHz radios have unique characteristics that provide operational advantages over other solutions.
- Narrow Beam Antennas: associated with 60GHz radios enable multiple radios to operate on the same rooftop or mast, and provide interference immunity from other 60GHz links.
- Easy to Install and Align: our radios are easy to install and align by non-expert installers with the use of a simple visual alignment tool provided with the product.
- High Data Transmission Security: Small beam sizes coupled with the oxygen absorption properties of 60GHz spectrum make the signal highly secure.
Rainfall and 60GHz Radios
Like all radio links that operate above 10GHz, intense rainfall significantly limits the distance over which 60GHz links can transmit data error-free. Rainfall statistics have been extensively studied throughout the United States to support millimeter-wave link deployments, primarily for cellular telephone network backhaul. These statistics allow us to determine how many minutes per year a 60GHz link of a given distance will be impaired due to short periods of intense rainfall. Note that intense rainfall occurs in relatively small, fast-moving rain cells, therefore these events are short-lived for any specific location. Based on the availability requirements of the application, the maximum link is determined based on the rainfall zone where the link is to be deployed. Our radios outperform other 60GHz radios due to the inclusion of a strong Forward Error Correction (FEC) code that is transmitted with the data. FEC provides another 6dB of link margin by correcting most of the errors due to heavy rainfall. This allows for up to 30% longer link distances.
