As Mobile World Congress Americas gets underway in San Francisco this week, a number of major US operators have shared details of their latest network initiatives.
Market leader Verizon Wireless will be demonstrating LTE using 3.5GHz Citizens Broadband Radio Service (CBRS) spectrum, in conjunction with Ericsson, Qualcomm and Federated Wireless. The aforementioned companies recently staged the first end-to-end demonstration of LTE-A carrier aggregation (CA) using CBRS spectrum.
AT&T Mobility, meanwhile, will team up with Ericsson and Qualcomm Technologies to demonstrate Gigabit LTE with Licence Assisted Access (LAA) technology for the first time publicly in the US. The demo will utilise the Ericsson Radio System’s small cell portfolio and the Samsung Galaxy Note8, powered by the Qualcomm Snapdragon 835 Mobile Platform with X16 LTE. LTE-LAA was standardised by industry body the 3GPP (as part of Release 13).
For its part, Sprint will be conducting real-world Massive MIMO testing at MWC Americas, in conjunction with Samsung. Previously, in June this year, the two companies tested 2.5GHz Massive MIMO functionality in Suwon, South Korea. Sprint wrote test cases and scenarios, and Samsung provided the infrastructure, network design, operation, data collection, and data processing resources.
