Wireless local loop (WLL) uses wireless technology to connect customers to telecom service providers instead of traditional wired connections. It provides a high-quality landline alternative to cellular networks for voice calls and fax/modem communications. WLL systems employ smart antennas and space-time processing to establish connections over allocated electromagnetic spectrum and offer advantages like lower maintenance costs and faster subscriber growth compared to establishing traditional wired local loops.
