Make It Happen: MeshCore Mesh Network in Arlington
In February 2021, Winter Storm Uri brought record cold and snow that crippled the Texas power grid, leaving millions of Arlington residents without electricity, heat, or water for days. Tornadoes strike the DFW Metroplex nearly every spring, and severe thunderstorms with damaging winds and hail are an annual certainty. Community members across Arlington are now building a MeshCore mesh network — small radio devices that let you send messages without internet, without cell towers, without any infrastructure. Just people and radios.
Why Arlington Is Building a Network It Can Count On
Arlington sits at the heart of the Dallas-Fort Worth Metroplex, positioned between the region's two largest cities in an area where severe weather is a way of life. The February 2021 Winter Storm Uri exposed the fragility of Texas infrastructure when temperatures plunged into single digits for days. The state power grid failed catastrophically, leaving over 4.5 million Texans without electricity — including most of Arlington. Residents went days without heat, water, or communication as cell towers lost backup power and networks collapsed. Tornadoes tear through North Texas regularly — the December 2015 outbreak killed 11 people across the metroplex, and Arlington has been struck repeatedly by EF2 and EF3 tornadoes that flatten neighborhoods in minutes. Severe thunderstorms with baseball-sized hail and straight-line winds routinely knock out power across the DFW area, leaving families unable to reach each other.
That's why community members are building a MeshCore mesh network — an independent emergency communication layer that doesn't depend on cell towers, internet, or the power grid. Each small radio device communicates directly with nearby devices using LoRa signals. Messages hop from device to device across the metroplex. The more DFW-area residents who join — from Grand Prairie to Mansfield, from Irving to Kennedale — the stronger this community safety net becomes.
Arlington's Communication Risks — and How Mesh Solves Them
Winter Storm Uri Proved the Texas Grid Can Fail Catastrophically
Arlington residents remember February 2021 vividly. Winter Storm Uri brought record cold that the Texas power grid was never designed to handle. Rolling blackouts became days-long outages. Pipes burst across the metroplex. Grocery stores closed. Cell towers went dark as backup batteries died. Millions of Texans — including Arlington families at AT&T Stadium, near Globe Life Field, and throughout the city — were left in freezing homes with no way to call for help or check on elderly neighbors. A community-built MeshCore mesh network with battery-powered nodes is designed to keep neighborhood communication alive when the grid fails and cell networks collapse.
Tornadoes Strike the DFW Metroplex Every Spring
North Texas sits at the southern edge of Tornado Alley, where warm Gulf moisture collides with cold fronts sweeping across the Great Plains. Powerful tornadoes have devastated DFW communities repeatedly — from the 1957 tornado that killed 10 people in Dallas to the December 2015 outbreak that destroyed hundreds of homes from Garland to Rowlett. Arlington itself has been hit by multiple significant tornadoes. When a tornado touches down near I-20 or along Collins Street, cell towers are among the first structures to fail — and the networks that survive can't handle hundreds of thousands of people trying to reach family simultaneously. A MeshCore mesh network creates communication paths that don't depend on vulnerable tower infrastructure.
Severe Thunderstorms and Hail Are an Annual Certainty
If you live in Arlington, you've experienced severe thunderstorms with damaging straight-line winds and hail the size of baseballs. These storms roll across North Texas from March through June, knocking out power to thousands of homes and businesses at a time. When a severe storm cuts power across South Arlington or near the University of Texas at Arlington campus, cell towers lose backup power within hours and networks become congested or fail entirely. A MeshCore device runs on a small battery that lasts for days and communicates by radio — no grid power, no internet, no cell towers needed to check on neighbors and coordinate during prolonged outages.
Flat North Texas Terrain Is Ideal for Long-Range Radio
Arlington's geography is actually a major advantage for mesh networking. The flat North Texas prairie means LoRa radio signals can travel remarkable distances with minimal obstruction. A single repeater mounted on a rooftop in Central Arlington can have line-of-sight coverage spanning miles in every direction — from Downtown Arlington west toward Fort Worth, east toward Grand Prairie and Dallas, and south through Mansfield toward Burleson. The flat landscape that makes the DFW Metroplex vulnerable to tornadoes and severe weather also makes it one of the best regions in Texas for building a long-range mesh network.
MeshCore in Arlington: How the Technology Operates
MeshCore uses LoRa (Long Range) radio technology to send encrypted messages between small, affordable devices. Each device acts as both a communicator and a relay — passing messages along to nearby devices. No Wi-Fi, no cellular, no internet required. A device in South Arlington can relay a message from Mansfield to Grand Prairie through a chain of community nodes.
Repeaters placed on rooftops and elevated structures dramatically extend range across Arlington's flat terrain. A single solar-powered repeater on a rooftop in Central Arlington can bridge from Downtown Fort Worth to East Arlington and beyond. Community members build this network together — each new device strengthens coverage for everyone. It's useful every day for private, off-grid communication — and critical when tornadoes, winter storms, or severe thunderstorms knock out traditional networks. Check the network map to see current nodes in your area.
Neighborhoods Building the Arlington MeshCore Network
Downtown Arlington & Entertainment District
Downtown Arlington and the Entertainment District anchored by AT&T Stadium and Globe Life Field form the urban core of the city. This area sees massive crowds during Cowboys games, Rangers games, and concerts — events where cellular networks routinely become overloaded. Mesh nodes on elevated structures near Division Street and Collins Street provide backbone coverage connecting the entire city. Repeaters here can reach west toward Fort Worth, east to Grand Prairie, and south through the UT Arlington campus toward South Arlington neighborhoods.
South Arlington & Kennedale
South Arlington stretches from I-20 through residential neighborhoods toward Mansfield and Kennedale. This area includes thousands of families living in suburban communities that experienced extended power outages during Winter Storm Uri. Mesh nodes in South Arlington create critical coverage linking these neighborhoods back to the central Arlington network and bridging south toward Johnson County. Residents here benefit from an independent communication channel that works when severe weather knocks out power and cell service across southern Tarrant County.
Grand Prairie & East Arlington
Grand Prairie sits directly east of Arlington along I-30, forming part of the continuous suburban sprawl between Dallas and Fort Worth. This area is home to major employers including the Grand Prairie Armed Forces Reserve Complex and DFW Airport workers. The flat prairie terrain provides excellent line-of-sight paths for LoRa signals. Mesh nodes here bridge the gap between Arlington and the Dallas side of the metroplex, creating relay paths that span the entire DFW urban corridor.
Irving, Euless & Bedford (Mid-Cities)
The Mid-Cities communities of Irving, Euless, and Bedford surround DFW Airport and form the northern tier of the Arlington area. These cities sit directly in the path of severe thunderstorms and tornadoes tracking from southwest to northeast across North Texas. When storms strike the airport area, transportation and communication infrastructure are immediately threatened. Mesh nodes in the Mid-Cities create relay paths independent of airport-dependent infrastructure, keeping families connected when weather grounds flights and knocks out power across the region.
