LTE TDD and LTE FDD network benchmark study

This 49-page report is specifically tailored to those operators and other entities who are interested in understanding the performance similarities and differences when the two duplex schemes are deployed in the same market, albeit in different frequency bands and with different channel bandwidths.

  • Key questions that we address in this 49-page report include the following:
  • What is the distribution of downlink and uplink throughput on an absolute basis for the two duplex schemes and how does the comparison change after normalizing the results for the amount of utilized spectrum?
  • How do key underlying network metrics, such as the signal strength (RSRP) and channel quality (SINR), differ between the two duplex schemes when the two networks are deployed in different frequency bands and with slightly different cell site densities?
  • How does the use of a higher frequency band and the amount of uplink network resources impact important uplink parameters, such as the transmit power and Power Headroom, which is a great means of identifying uplink coverage limitations?
  • What is the relationship between the downlink throughput, the reported SINR and the received signal strength (RSRP), and how does it differ between the two LTE networks?
  • What is the relationship between the uplink throughput, the transmit power, and the downlink received signal strength (RSRP), and how does the relationship differ between the two LTE networks?
  • How does edge of cell performance for the two LTE networks compare with the performance throughout the entire cell coverage area?
  • What are the likely performance metrics for typical user applications, such as Skype Video and Skype Voice, and how do these metrics vary between LTE TDD and LTE FDD.
  • What incremental benefit does a Category 4 device provide operators who are using 20 MHz LTE TDD channel bandwidths and Configuration 2, the most common configuration which provides roughly 75% of the resources in the downlink and 25% of the resources in the uplink?
  • What phenomenon did we observe which suggests the LTE TDD results could have been even better than what we recorded?
