Building-to-Building Wireless: PTP and PTMP wireless networks
Point-to-point and point-to-multipoint wireless solutions can provide reliable network connections in circumstances where it simply isn’t practical - or preferable - to employ a wired network configuration. Taking into consideration such variables as potential for line-of-sight propagation or the lack thereof, signal degradation due to ambient noise, environmental fade, encryption, and spectrum selection, among others, Gyver Networks can provide the optimal strategy to allow you sustained connectivity despite the obstacles presented. We work with:
Line-of-site and non-line-of-site point-to-point technology
RF solutions ranging from 900MHz up to 80GHz
Variable distance point-to-point and point-to-multipoint microwave-based networks
Fixed and variable gain amplification and contour error-reduction technologies
WiMAX (802.16d) and mobile WiMAX (802.16e) networks
Frequency-hopping spread spectrum (FHSS) and beam steering/tracking technologies
Let Gyver Networks devise a point-to-point solution that fits your needs. Contact us today for a free consultation.

Frequently Asked Questions
Wireless can do more than just connect your end users to a transmission source located in the same facility – in fact, it can connect facilities geographically separated by miles! We regularly receive questions regarding the efficacy and performance of point-to-point wireless bridges to extend LANs and for other wireless backhaul applications, which we have consolidated here for your convenience:
What is point-to-point wireless?
A point-to-point or point-to-multipoint wireless link is used to extend – or bridge – existing LANs (local area network) or WLANs (wireless local area network) which are separated physically and/or logically.
What data speeds can a point-to-point wireless bridge provide?
Point-to-point wireless links are capable of providing speeds as high as 6 Gbps, depending on frequency, distance, hardware configuration, and other mitigating factors.
When creating a long-distance point-to-point wireless bridge, what is the maximum effective range?
A variety of factors go into determining the effective range of a point-to-point wireless bridge, but frequency and line of sight are the primary considerations. Lower frequency, non-line-of-sight bridges routinely link sites over 100 miles apart at speeds up to 300 Mbps; higher frequency, line-of-sight links have much shorter range, but provide considerably higher throughput speeds. Factoring the data throughput speed required and the distance between sites determines the viability of a given point-to-point wireless bridge solution.
How do physical impediments such as trees and buildings affect the performance of a point-to-point wireless bridge?
The short answer: NEGATIVELY! The wood in trees absorbs microwave RF (radio frequency) signal, while each leaf behaves as a tiny mirror, breaking up the signal and reflecting it off in a different direction than the adjacent leaf. Metal and brick buildings reflect signal, while glass refracts and distorts it.
Does weather affect the performance of a point-to-point wireless bridge?
The short answer: only if the link is not properly engineered. At higher frequencies, weather has a substantial impact on point-to-point wireless bridges due to the narrow beam employed. The longer wavelengths of lower frequencies are not significantly impacted by a single raindrop or snowflake, but the higher signal absorption coefficient of high frequency, shorter wavelengths (generally above 11 GHz) by precipitation means that weather can potentially be a major impediment to link connectivity, as are other forms of atmospheric attenuation such as resonance of the oxygen molecule. Additionally, buildup of snow and ice on the antennas themselves can impede signal at either end of the link. These considerations are all accounted for during the engineering phase of the project.
What other sources of interference affect the performance of a point-to-point wireless bridge?
Other RF signals on the same unlicensed band can interfere with the connectivity of a point-to-point bridge. Point-to-point links over bodies of water can also present problems if not engineered correctly, employing principles such as spatial diversity, etc.
How secure are point-to-point wireless bridges?
Point-to-point wireless bridges are even more secure than other wireless networks. In addition to the standard AES 256-bit encryption supported by nearly all licensed/unlicensed point-to-point hardware, higher frequency links operate on wavelengths for which packet capturing devices do not exist. Additionally, that smaller wavelength means that a potential intruder would have to be directly in the path of a very small beam to even attempt to access the signal. And finally, proprietary encryption algorithms between matched pair radios make circumventing security on a point-to-point wireless bridge nearly impossible.
Do I need to secure FCC licensing to create a point-to-point wireless bridge?
LICENSED BY FCC: All other frequencies, e.g., 1.8 GHz, 3GHz, 4.5GHz(Gov’t), 4.9GHz, 6 GHz, 7 GHz(Gov’t), 11 GHz, 13GHz, 15GHz, 18 GHz, 23 GHz, 38 GHz
