All LTE networks are not created equal
Deployments around the world have different conditions.
AIRCOM addressed the following spectrum bands: 700 MHz 1700 MHz 1800 MHz 2600 MHz
Bandwidth 10 MHz FDD

LTE Download results have a greater variance than Upload results
Technologies - LTE, CDMA, UMTS, HSPA, GSM Time line - mid June 2011 to mid January 2012 Morphologies
Dense urban Urban Sub-urban
Data calls FTP large file transfer in UL and DL to test retainability FTP small file transfer in UL and DL to test accessibility FTP & HTTP file transfer to test throughput ICMP /ping test to check round trip time / latency
