LTE modem meets latest 3GPP standards

Samsung Electronics Co. Ltd has announced the first Long Term Evolution (LTE) modem that complies with the latest standards of the 3rd Generation Partnership Project (3GPP), which were released in March. Using release 8 of the 3GPP, this LTE modem is a significant upgrade from the previous standard released in December 2008.

The modem, branded the Kalmia, supports download speed up to 100Mbit/s and upload speed of 50Mbit/s within the 20MHz frequency bandwidth. Users of a mobile device equipped with the LTE chipset can download a high-definition (HD) movie file (800Mbyte) in one minute at speeds of 100Mbit/s, while simultaneously streaming four HD movies with no buffering.

Samsung also announced it has successfully developed a 3G baseband modem based on the Release 7 standard with a High Speed Packet Access (HSPA) Evolution platform. This modem, branded the Broom, allows download speeds of up to 28Mbit/s and upload speeds of 11.5Mbit/s. This makes the Release 7 more than twice as fast as the Release 6 HSPA Service, which had a maximum download speed of 14.4Mbit/s.

Because the LTE and all other HSPA evolution models share the same platform, the new LTE modem is fully compatible with earlier standards. Through this technology, a mobile communications service provider can upgrade to HSPA service or evolve into a LTE network simultaneously in order to convert their existing networks to broadband.

In the future, this flexibility will be crucial as wireless mobile service providers will require compatibility with pre-existing systems, in order to offer LTE in urban areas while still supporting 3G in suburban or rural areas. The modem offers a multi-mode, which is a major requirement for LTE developers who are calling for inter-operability within pre-existing 3G networks.

"Our latest LTE standard chipset will help realize the world's first commercial LTE device," said JongKyun Shin, executive VP and head of the mobile communications division at Samsung. "Currently, Samsung is partnering with LTE developers preparing for a LTE service launch in 2010 and will unveil a variety of LTE devices of different types and with diverse features and options, including memory cards, handheld devices and MID."

Separately, Samsung has also developed the mobile WiMAX (IEEE 802.16e) modem chip, a product that is already resonating in the mobile market. The company has already adopted the modem into commercial WiBro handsets in Korea. With this new modem, Samsung has delivered WiMAX and LTE model solutions, which are the two major wireless mobile communications systems for the next generation. The company has also demonstrated a full lineup of modems from 2G/3G to modems for the next generation of mobile telecommunication systems with its HSDPA Evolution modems.
