Chicago mayor Rahm Emanuel and Sprint announced yesterday a new lineup of investments in the city, meant to bring significant jobs and infrastructure over the next few years. Dubbed 'Sprint For Chicago', this plan brings 300+ new jobs to the area, as well as he installation of new cell sites to deliver the first Sprint LTE-A connections.

LTE-Advanced (LTE-A) takes advantage of the multiple frequencies Sprint has available at this time. With aggregation at the carrier level, the typical 1900Mhz LTE will be used for upload speeds, and the 2500Mhz frequencies will be used for download. The 2500Mhz band was previously used in Sprints first 4G WiMAX technology, and has more recently been used in Sprint Spark.

In a quote from Sprint to Wireless Week , “Through the use of carrier aggregation we can take advantage of two 3x20 CA within our 2.5GHz band, but also inter-band carrier aggregation with 800MHz and 1.9GHz, TDD-FDD CA with 1.9GHz and 2.5GHz and intra-band carrier aggregation within 1.9GHz."

Since 2012 Sprint has invested more than $500 million dollars in Chicago, and Sprint customers have increased by more than 600% in that same time. While there aren't any details on LTE-A and the exact speeds or compatibility of devices, this is a major step forward for Sprint in terms of wireless technology.
