Unlicensed sub-6GHz bands are ideal for Point-to-Multipoint solutions with a range of 3 to 5 miles from the radio pole mount. Unlicensed 5.1GHz to 5.8GHz is used for point-to-point as well as point-to-multipoint products and is essentially free of rain, snow, and fog interference.
Fremont CA: Information and communication technology (ICT) professionals from both wireless and wireline companies see their businesses merge and broadband deployment lines blur. In the age of a global pandemic, the challenge of expanding or improving broadband services is becoming increasingly important.
Copper, fiber, or fixed wireless access (FWA) are the most common options for broadband delivery to IoT, homes, and businesses. However, network providers must deal with the reality that fiber or copper is not available in many service areas. As a result, they must devise innovative deployment strategies to provide fast, dependable broadband service.
Basic Deployment Considerations:
Line of Sight (LOS) Conditions
LOS refers to the ability to see or have no obstruction between two radio nodes in a network. Each piece of equipment operating on a different spectrum and/or technology has different LOS requirements, so it is critical to understand each condition.
• Unobstructed Line of Sight (LOS). A clear line of sight between two wireless radios that is typically required for equipment operating at a specific spectrum, such as 60GHz (V Band) or 80GHz (E Band).
• Direct Line of Sight (nLOS). A condition between two radios in which a portion of the radio path is partially obstructed by something like a tree canopy. LTE technology with Multiple-input Multiple-output (MIMO) equipment is best suited to this. It increases the capacity of a radio link by employing multiple transmission and receiving antennas to take advantage of multipath propagation. This is best accomplished with equipment that operates in the FWA unlicensed mid-band spectrum (such as 3.5GHz).
The FWA spectrum may differ in each country, but a few commonalities allow for global equipment commonality.
Furthermore, the bandwidths of the spectrum channels largely depict the available speed capabilities.
Numerous FCC-licensed bands are available, including 6GHz, 11GHz, 18GHz, and 23GHz, allowing operators who cannot accept channel interference due to customer service level agreements to provide Point-to-Point Gigabit FWA solutions. Companies selling the solution can help with the filing of the FCC license for the deployment of the link. It will ensure that no competing infrastructure will obstruct their service offering. Millimeter-Wave (mmWave) products using E-Band and V-Band include technologies for high-speed (10Gbps) high-capacity wireless links, ideal for fiber extension in suburban and urban areas. Using high-frequency microwave in the E-Band (70-80GHz) and Mesh in the V-Band (60GHz) spectrum, links can be densely deployed in congested areas without interference and without the need for digging to deploy fiber.
