Qualcomm has announced an interoperability solution to the mishmash of LTE frequency bands that pepper the globe. Right now it’s impossible for most Canadian devices to roam on European and Asian carriers running LTE, but that will soon change with the RF360, a bevy of chips, transceivers and antennas that promises harmony for over 40 LTE channels.
The RF360′s transceiver chip, the WTR1625L, is the first in the business to offer carrier aggregation across most of its LTE bands. You may be familiar with this term in the context of Dual Carrier (or Dual Channel) HSPA+, which is provided by Rogers, Bell and TELUS in many of the larger Canadian cities. This allows wireless companies to combine multiple 5Mhz or 10Mhz channels effectively into one downstream signal, promising, alongside LTE-Advanced, speeds of up to 300Mbps in the downlink.
RF360 isn’t expected to hit the streets, or your nearest phone, until the end of 2013 at the earliest, but when it does expect Rogers, Bell and TELUS to significantly expand its LTE roaming deals.
