Does RedCap replace NB-IoT or LTE-M?

No. RedCap is mid-tier: 85-226 Mbps, days-to-months battery. NB-IoT and LTE-M are LPWA: <1 Mbps, 10+ year battery. They serve different device classes. RedCap replaces LTE Cat-4 for devices that need more throughput than LTE-M but cannot justify full 5G NR cost and power.

Can I buy RedCap modules today?

Yes. Qualcomm X35, MediaTek, Semtech FX86E, Fibocom, Quectel, and Telit Cinterion are shipping. But specify LTE Cat-4 fallback — 5G SA coverage is not ubiquitous. Without fallback, the device loses connectivity outside SA zones.

AT&T killed NB-IoT — should I stop using it?

AT&T's decision was spectrum economics, not a technology failure. NB-IoT remains viable in Europe and Asia where operators continue supporting it. But for 5+ year deployments in the US, LTE-M is the safer LPWA choice. Check your target operator's stated roadmap before committing to NB-IoT for new designs.

85-226 Mbps. Bateria en dias no anos. No es LPWA.

5G RedCap no es una tecnologia LPWA. No compite con NB-IoT o LTE-M por el mercado de sensores de ultra-bajo consumo. Ocupa el nivel medio que la IoT celular nunca ha servido adecuadamente: dispositivos que necesitan mas del techo de 1 Mbps de LTE-M pero no pueden justificar el costo de modulo de $80-150 del 5G NR completo. Para estos dispositivos — camaras de vigilancia, gateways industriales, routers de vehiculos conectados — RedCap ofrece una alternativa nativa 5G-SA con network slicing.

La Brecha de Nivel Medio que RedCap Llena

RedCap: 85-226 Mbps down, 50-120 Mbps up, ancho de banda maximo 20 MHz, 1-2 antenas. eRedCap (R18): 5 MHz, antena unica, ~10 Mbps. Costo de modulo objetivo $10-15.

Realidad de Bateria: RedCap No Es de Bajo Consumo

RedCap reduce el consumo frente al 5G NR completo, pero no se acerca al territorio LPWA. Un dispositivo RedCap en transmision activa consume cientos de milivatios, no microvatios. La vida de bateria se mide en dias a meses. Regla practica 2026: si el dispositivo funciona a bateria y despierta menos de una vez por hora, use NB-IoT o LTE-M.
