Greenpacket Demos 1st High-Gain TDD LTE Modem At Mobile World Congress


Greenpacket recently announced that it will be showcasing the first high-gain TDD LTE (News - Alert) modem at the 2012 Mobile World Congress in Barcelona, Spain that places during February 27th to March 1st. Greenpacket’s first LTE offering has been designed as a multi-band 2.3Ghz to 2.7Ghz USB modem which will be made available across the globe within Q1 of 2012.


In a release, James Wang, Senior Vice President of Innovation, Strategies and Development (ISD) of Greenpacket said, “We fully understand the performance issues of WiMax and LTE USB dongle. The 5 dBi of extra gain provided by the modem will set a clear performance benchmark in the 4G LTE industry. By improving the device performance uplink, we can significantly combat the asymmetries between the uplink and downlink radio resources thus enhancing operators’ services by providing end users better connectivity; anywhere, anytime. LTE’s uplink is based on the SC-FDMA scheme, which has lower Peak to Average Ratio (PAR) than WiMAX’s (News - Alert) OFDMA scheme, and we expect major uplink performance improvements over WiMAX.”

The USB modem is based on the 4G WiMAX UH modem design which makes it a performance-based portable and flexible unit. At present Greenpacket is the third largest supplier of 4G WiMAX devices across the globe.

The company is expecting to take advantage of the expanding subscriber base for TDD LTE which in 2012 is approximately 25 percent of the total 31 million LTE subscribers. 33 percent of the user base again is keen on exploiting the advantages of a USB dongle.

Kelvin Lee, Senior General Manager of Greenpacket said, “There has been a growing demand for higher bandwidth and more reliable data services. Operators need to be able to harness the power and speed of LTE in delivering superior and quality services to their subscribers. We are duplicating a proven product based on our experience, to ensure operators the ability to transition and commercialize their services smoothly and successfully as LTE is fast becoming the main telecommunication standard for operators globally.”

The high-gain TDD LTE device has successfully cleared the chipset Interoperability-test (IOT) for a number of leading TDD LTE base-stations operating across multi-band 38/40/41. Delivering an enhanced mobile broadband experience, the modem which can support Windows, Linux, and Mac OS among others, can function seamlessly even in hostless mode and is not dependent on a driver.

Lee said, “Greenpacket is working diligently to be the partner of choice for enabling high speed mobile broadband experience on TDD LTE. According to GSA (News - Alert), band 2.3 to 2.7 GHz covers 90 percent of the current TDD LTE market and a wide-band modem will allow operators to generate more revenue from roaming business.”
