Massive MIMO Arrays Expand Beyond Macro Cells
Massive MIMO antenna arrays, once deployed almost exclusively at macro cell towers, are moving into small cell and indoor deployment as carriers push 5G capacity into dense urban environments and large commercial buildings. This expansion requires antenna designs that pack dozens of elements into significantly smaller enclosures than tower-mounted equipment, a miniaturization challenge that favors vendors with advanced simulation capability over those relying on legacy tower antenna designs. Several carriers have reported capacity gains of three to five times over legacy sector antennas after deploying massive MIMO at high-traffic urban sites, accelerating rollout budgets across metropolitan markets.
Market Impact: Requires 15,000 new small cell sites
