Describe the HSPA+ (High Speed Packet Access Plus) and LTE (Long Term Evolution) cellular networking technologies.
What will be an ideal response?
ANSWER: The HSPA+ began as a 3G technology released in 2008 that uses MIMO and sophisticated encoding techniques to achieve a maximum 168 Mbps downlink throughput and 22 Mbps uplink throughput in its current release. To achieve such speeds, HSPA+ uses limited channels more efficiently and incorporates more antennas in MIMO transmission. However, faster and more flexible technologies, such as LTE, are overtaking HSPA+ in popularity. LTE is a 4G technology that uses a different access method than HSPA+. While the latest version, LTE-Advanced, can theoretically achieve downlink data rates of up to 1 Gbps and uplink rates up to 100 Mbps, actual speeds are significantly less. LTE is currently the fastest wireless broadband service available in the United States.
