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.

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
![City of Dallas 13 Backhaul Power Option](https://www.arranetworks.com/wp-content/uploads/2021/01/Backhaul-Power-Option@2x-681x1024.jpg)
Sources providing Backhaul are powered through POE at 48VDC

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.
K E Y D I F F E R E N T I A T O R S _
- 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”)
