US mobile giant Sprint Corporation has successfully demonstrated transmission speeds of 1Gbps ‘over-the-air’ at its laboratory near Silicon Valley, California. In addition, the mobile giant also unveiled its new ‘Sprint Spark’ tri-band technology, which combines Frequency Division Duplex Long Term Evolution (FDD-LTE) 800MHz spectrum, with 1900MHz frequencies and 2500MHz Time Division Duplex (TDD)-LTE spectrum, designed to deliver a seamless customer experience via tri-band wireless devices. Going forward, Sprint plans to deploy Sprint Spark in 100 of America’s largest cities over the next three years, with initial availability in the markets of New York, Los Angeles, Chicago, Tampa and Miami. The first smartphones with Sprint Spark capability are scheduled for customer availability in early November. Sprint Spark is expected to deliver ‘real-world’ downlink speeds of 50Mbps-60Mbps.
According to Fierce Wireless the vendors that will roll out Sprint Spark are Alcatel-Lucent, Samsung and Nokia Solutions and Networks (NSN). Noticeably absent from the list is Ericsson, which is Sprint’s managed services vendor for its entire network and also a key supplier for its Network Vision upgrade programme.
