Tom Sawanobori, Senior Vice President and Chief Technology Officer of CTIA-The Wireless Association, was featured on Richard Bennett’s High Tech Forum podcast series earlier this week. Speaking with Bennett on the state-of-play in the wireless industry, Sawanobori addressed mobile broadband growth, the need for more spectrum, unlicensed spectrum coexistence, and the development of next-generation networks.
When asked his view on LTE-U and Wi-Fi coexistence, Sawanobori said:
“The whole concept of LTE-U is to take the great attributes of 4G LTE – the security, the mobility, connecting to the same core network, providing good, solid throughput – with a good coexistence mechanism with Wi-Fi in a small cell so you can have what’s called a supplemental downlink…Wi-Fi is a great technology. We need both of these to work well and to co-exist. Studies and tests have shown that it does co-exist well, and recent fairly stressful lab tests show that when you replace a Wi-Fi node with an LTE-U access point on the same channel, the Wi-Fi basically performs the same or even better.”
