Point-to-multipoint (PTMP) wireless bridges can deliver high-speed internet across a multi-tenant property without running cable to every tenant. This guide covers the planning steps and how to limit interference in Los Angeles.
Planning a PTMP network
Planning matters because Los Angeles has dense building clusters, varied terrain and city regulations.
Site survey
Survey the property and the area around it. Find mounting locations for the base station and subscriber units, and check for line-of-sight obstructions such as tall buildings, trees and hills.
Frequency selection
Pick bands that comply with FCC rules and keep interference down. 5 GHz is popular for PTMP because it balances range and bandwidth, but it needs clear line of sight.
Capacity and coverage
Estimate the number of tenants and devices and calculate bandwidth for peak use.
Equipment
Choose PTMP bridges rated for outdoor use, in weatherproof enclosures. Gigabit models leave room to grow.
Permits
Check local zoning and get any permits for antenna installation. Check local building code and aesthetic rules before you mount anything.
Limiting interference
Los Angeles has a lot of wireless devices and networks, so interference is a main concern.
- Directional antennas focus the signal toward subscriber units and reduce spillover.
- Channel planning: Assign non-overlapping channels to different links, and use spectrum analysis to find the least congested ones.
- Height and placement: Mount antennas high to avoid obstacles and reduce multipath reflections.
- Power control: Set transmit power to the minimum for a reliable link.
- Monitoring: Scan periodically for new interference and adjust settings.
Benefits for multi-tenant buildings
- Lower cost: No fiber or copper run to each tenant, which cuts installation time and material.
- Fast deployment: Bridges install quickly with little disruption to tenants.
- Easy growth: Add tenants by adding subscriber units, without major infrastructure changes.
- Speed: Modern PTMP equipment supports gigabit speeds for streaming, video conferencing and cloud applications.
- Management: Administrators can monitor all connections from a single base station.
Our PTMP work
Gbit Tech can plan and install PTMP wireless links as part of a UniFi network in Los Angeles. That includes site surveys, interference analysis and channel planning, and weather-resistant gigabit equipment, with local permit rules checked first. We work to keep tenant disruption to a minimum.
