Is Linear Wi-Fi FEM Dead? Non-linear FEM as the Future?

Is Linear Wi-Fi FEM Dead? Non-linear FEM as the Future?

After meeting with several router clients, I have calmed down. It is not just the Wi-Fi FEM track that is dead, but also the home router market. Despite the bleak router market, clients are still willing to meet with me for broader discussions. On one hand, many manufacturers that previously promoted Wi-Fi FEM are gradually … Read more
