LTE networks are getting more and more common, allowing you to browse the web instantly, stream content, or download movies at high-speed. You’ll find LTE support in a number of Xperia™ smartphones, all the way from the just announced Xperia™ Z to the Xperia™ ion. Each device has a particular range of LTE bands, with corresponding regions that support the service. Read on to get the full list of LTE-enabled smartphones, supported bands, and the available countries where you can use LTE.
Among the impressive specs you’ll find for the recently announced Xperia Z – quad-core CPU, 5’ 1080p HD display, and HDR video camera – don’t forget that you’ll also find support for LTE. It’s the latest Sony superphone with LTE capability, and joins an already extensive list of Xperia™ LTE-capable smartphones.
LTE stands for 3GPP Long Term Evolution, and is a standard for wireless data communications technology and an evolution of the GSM/UMTS standards. This technology increases the capacity and speed of wireless data networks using DSP (digital signal processing) techniques and modulations that already provides peak rates of 100 Mbit/s downlink and 50 Mbit/s uplink and QoS provisions permitting a transfer latency of 10-15 ms and is evolving to beyond 300 Mbps. With LTE, the ability to manage fast-moving mobiles is supported, as well as multi-cast and broadcast streams. LTE supports scalable carrier bandwidths, from 1.4 MHz to 20 MHz and supports both frequency division duplexing (FDD) and time-division duplexing (TDD).
LTE frequency bands
The LTE standard can be used with many different frequency bands. The deployment is increasing rapidly among the world. As of today 700, 850, , 1900 and 1700/2100 MHz bands are used in North America. South America uses 700, 1700/2100 and 2600 MHz. 800, 900, 1800, 2600 MHz bands are used in Europe. You’ll find the 850, 1500, 1800, 2100, 2300 and 2600 MHz bands used in Asia. And Australia uses 1800 MHz. As a result, phones from one country may not work in other countries. Since the LTE standard is fairly new to the operators there are very few roaming agreements between different countries and operators when it comes to LTE roaming (HSPA roaming already exists). In the future when roaming agreements are in place users will need a multi-band capable phone for roaming internationally. That will be less of an issue if you’re using an Xperia™ smartphone, as they are already multi-band capable (with the exception of Xperia™ SX) and support at least two bands or more. The table further down lists the LTE bands supported by Xperia™ smartphones.
The feature image used for this article indicates current countries in green where there is an existing (commercial) LTE network that Xperia™ smartphones can connect to. Please note that many more regions will have LTE in the near future. Furthermore, the availability of LTE networks is operator-dependent and may vary from area to area within a country.

The bands are listed from (1) to (29) FDD and (33) to (44) TDD, and separated by frequencies, as defined by E-UTRAN (Evolved Universal Terrestrial Radio Access), the air interface for LTE. In the uplink operating band, there are three physical channels used for initial access and carrying control information. In the downlink operating band, there are several physical channels that carry allocation information, data transmission, broadcast transmission, and other basic system information.
