Project

ARRA mesh network platform solution has been chosen for a school connectivity program paid for by US Federal Cares Act funding to be deployed in the City of Dallas.

O B J E C T I V E _

Provide broadband connectivity to the unconnected students in the Dallas area. Speed and flexibility of deployments were high requirements followed by network resiliency and easy-to-use remote management of all facets of network operations.

Discussions are underway with the City of Dallas to deliver Phase 2 of the project which will provide Wi-Fi to students and households throughout the city.

Deployment Map

Dallas Deployment

How Units Are Configured

  • Nodes are up to 200 meters apart in suburban environments
  • Overlapping node coverage ensures connectivity in case of any individual node outage
  • 5GHz connects the nodes
  • 2.4 GHz distributes Wi-Fi to the students’ homes

Power Options

Backhaul Power Option

Sources providing Backhaul are powered through POE at 48VDC

Clearworld Solar Pole

ALL other nodes are powered by solar (minimum 24VDC)

Rural vs. Urban Deployment

Most unconnected areas have access to nearby fiber – but can’t afford to distribute that connectivity across the landscape to individual homes and businesses. ARRA’s innovation solves this problem for both urban and rural deployments, but there are differences.

  • Distance. In suburban environments, routers are placed up to 200 meters from one another. However, in rural environments, the routers can be up to a mile away from one another without loss of performance.
  • Urban and suburban environments allow multiple users to access unique nodes, where rural applications may only yield one family per node.
  • Factors to consider:
    • Line of sight
    • Landscape features (e.g. hills/depressions)
    • Antenna height

Backhaul Requirements

No-fuss plug and play backhaul via existing fiber, copper, LTE, Ethernet, or satellite.

  • Provides ultimate flexibility
  • Automatic load balancing
  • Organic network growth won’t break the network like traditional methods.
  • Provides each node with the opportunity to optimize its signal (the more points of backhaul, the better)
  • Helps ensure network stability
  • Eliminates single point of failure (but will run off a single “base”)
