Arizona and New Mexico Networks

The desert Southwest presents a paradox for LoRa mesh: the flat terrain and hot, dry climate create both advantages (excellent solar harvest, low vegetation obstruction) and challenges (thermal management critical, water scarce for cooling).

Phoenix Metro

The Phoenix metropolitan area is one of the largest flat urban areas in the US. With no significant terrain relief within the metro, repeater height becomes even more critical than in mountainous regions.

• Flat terrain strategy — Any tall structure (water tower, high-rise rooftop, South Mountain Park ridgeline at 2,690 ft) dramatically outperforms ground-level nodes. South Mountain provides coverage over the entire east and south valley.
• Thermal management critical — Phoenix summer temperatures routinely exceed 45°C (113°F). Enclosures in direct sun can reach 70-80°C internally, which destroys electronics and accelerates battery degradation. All outdoor enclosures require radiation shielding, venting, or both.
• Solar abundance — Phoenix averages 299 sunny days per year. Panel sizing is easy; even a small 5W panel produces consistent output. Even winter months see 5-6 peak sun hours daily.
• Active community — Phoenix and Scottsdale have an active Meshtastic community; check meshmap.net for current node positions.

Tucson

Tucson sits in a basin surrounded by mountain ranges (Santa Catalinas to the north rise to 9,157 ft, Rincons to the east, Santa Ritas to the south), providing exceptional repeater sites. Mount Lemmon (9,157 ft) above the city is accessible by road and could serve as an extraordinary regional repeater reaching into Mexico and across southern Arizona.

Albuquerque and New Mexico

Albuquerque sits at 5,312 ft elevation in the Rio Grande Valley, with the Sandia Mountains immediately to the east rising to 10,678 ft. This topography mirrors Salt Lake City: urban valley with immediate high-elevation repeater sites.

• Sandia Peak — The Sandia Crest (10,678 ft) is accessible by tram and road, with existing communications infrastructure. A repeater here would cover the entire Albuquerque metro and potentially reach Santa Fe 60 miles north.
• Santa Fe — Sits at 7,199 ft; excellent radio horizon, active ham community.
• Rio Grande corridor — Potential for a backbone mesh from Taos through Albuquerque to Las Cruces following the Rio Grande valley.

Desert Deployment Notes

• Monsoon season (July–September) — High humidity and intense localized thunderstorms. Ensure all enclosure seals and cable glands are properly maintained. Lightning risk increases significantly during monsoon.
• Dust and particulates — Haboobs (dust storms) can sandblast solar panels; use tempered glass panels rather than cheaper plastic-faced ones.
• Very long range achievable — Desert air is dry, low-loss, and flat. Elevated repeaters can achieve 50+ mile range in favorable conditions.
