Why FDD is the preferred choice for LTE

According to GSA (Global mobile Suppliers Association), 200 commercial LTE networks in 76 countries were launched by 31 July, 2013 of which 182 networks are based on FDD technology.

LTE has seen good traction as 443 operators in 130 countries are investing in LTE technology. 1800 MHz is the dominant band for LTE deployment and is currently used in over 43 percent of the networks.

Presently, there are 84 commercially launched networks in 45 countries supporting 20 million subscribers. Around 23 network deployments in 1800 MHz are in progress or planned.

As per forecast the number of commercial LTE networks will reach 260 by December, 2013.

LTE is a single global 3GPP standard with an FDD mode for operators using paired spectrum and TDD mode for operators using unpaired spectrum. 9 networks were deployed in TDD mode (sometimes referred to as TD-LTE) and 9 networks are using both FDD and TDD modes.

In 2013, 54 operators launched LTE service. Countries where LTE service was launched in 2013 include: Chile, Iceland, Iraq, Lebanon, Malaysia, New Zealand, Paraguay, Qatar, Spain, Thailand, US Virgin Islands and Venezuela. 146 commercial LTE networks were in service at the end of 2012.

Alan Hadden, president, GSA said, “In this interim announcement GSA confirms that 106 LTE networks were commercially launched in the last 12 months, representing 112 percent annual growth. LTE is a mainstream mobile broadband technology and is the fastest developing mobile system technology ever.”

In terms of subscriber, LTE presently has 90.2 million as on Q1, 2013 of which North America contributes around 54.2 percent and Asia Pacific contributes around 41.4 percent. In terms of user devices, LTE supports 948 user devices as on July, 2013.
