Why 4G’s OFDM radio waves have a speed limit

Why do 4G’s OFDM radio waves have a speed limit? Before 5G and Starlink, there was WiMAX: the wireless broadband technology once hailed as the future of mobile internet. Backed by major players like Intel, Sprint, and Clearwire, WiMAX aimed to deliver fast, reliable internet on the go. But despite its early promise, WiMAX quickly fell behind and was ultimately crushed by 4G LTE. Why? In this video, we cover the technical and strategic reasons why WiMAX failed: WiMAX used orthogonal frequency-div

🎯 OFDM vs. OFDMA: Entenda a Diferença e Onde São Aplicados! 🚀 Você sabe qual a diferença entre OFDM e OFDMA? 🤔 Ambos revolucionaram as telecomunicações, mas têm aplicações distintas e são regidos por normas específicas! Vamos lá: 🔸 OFDM (Orthogonal Frequency Division Multiplexing): Técnica de modulação usada em Wi-Fi (802.11a/g/n/ac), DVB-T e LTE. Divide o sinal em múltiplas subportadoras, otimizando a transmissão de dados. 🔸 OFDMA (Orthogonal Frequency Division Multiple Access): Evolução d
