ARRA mesh network platform solution has been chosen for a school connectivity program paid for by Cares Act federal funding to be deployed in Dallas Independent School District.
O B J E C T I V E _
Provide broadband connectivity to the unconnected students in the Dallas ISD. 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 Dallas ISD to deliver Phase 2 of the project which will provide Wi-Fi to all students within the district.

How Units Are Configured
- Nodes are ~ 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
Hubs (Backhaul) are on 120V using supplied POE’s via ethernet
ALL other nodes are powered by solar (48V)
Poles Used For Deployment
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 urban environments, routers are placed 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 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
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”)
