Multi-Antenna Technologies for Unlicensed Private Network Deployments

by Jiancao Hou | 3Q 2020 | IN-5927
With the rapid growth of data traffic, Mobile Network Operators (MNOs) are looking for new ways to cope with their soon-to-be-overloaded networks. One promising strategy is to offload their best-effort traffic to unlicensed and shared spectrums, using technologies such as pro Long-Term Evolution-Wireless Local Area Networks (LTE-WLANs) Aggregation (LWA) and Licensed Assisted Access (LAA). For the LWA technology, MNOs are required to own WLANs and reuse their large numbers of installed WLAN Access Points (APs) to assist cellular communications. However, according to ABI Research’s latest Wi-Fi Customer Premises Equipment SOHO/Consumer and Enterprise Market (MD-WLEQ-163) Market Data, 95% of MNOs today do not have Carrier WLANs; therefore, the native cellular-based LAA technology becomes their preferred option. Due to the dynamic spectrum access nature of both technologies (e.g., licensed access can take over when unlicensed access fails), communication reliability can be guaranteed.
