Development of a WiMAX Radio Head, compatible with Multi-antenna systems by Sumitomo Electric

March 19, 2010 · Filed Under Trendy Products · Comments Off on Development of a WiMAX Radio Head, compatible with Multi-antenna systems by Sumitomo Electric 

Sumitomo Electric WiMAX RRH1In a new wireless network setup, the power amplifier has been relocated from the base station inside a building to a location beneath an antenna outside as an independent Remote Radio Head (RRH) unit. The RRH is linked via a fiber optic cable to the base station providing flexibility for base station placement. Additional benefit in placing the amplifier close to an antenna, is in reducing transmission loss, resulting in saving a large amount of electricity, where otherwise would be wasted in a conventional power amplifier. On the other note, WiMAX as one of the next generation wireless broadband technology, if not the only one, have not been fully utilized, one for a lack of infrastructure and other being the interference of radio waves, specially in urban areas with proliferation of antennas.

Development of Low Power, Low Noise All-Digital Phase Lock Loop LSI by NEC

March 4, 2010 · Filed Under Green Tech, Trendy Products · 1 Comment 

NEC ADPLL LSIAs demand for short distance radio communication for such systems as remote controllers, alarm systems and automatic meter reading is on the rise, one major concern that has preoccupied manufacturers of these systems is their power consumption, requiring these systems to have a longer battery life. At the same time, small and lightweight criteria for wireless devices imposed by the market demand forcing manufacturer to further reduce the battery, however, reduced battery size will translate to reduced total available energy. For such battery driven devices one way to extend the battery life is through intermittent operation through use of all digital PLL (Phase Lock Loop) offering a quick operations as well as their advantage in eliminating large on-chip passive filters. In comparison analog-based PLL does not constitute a good solution due to their long start-up time. Based on this requirement, NEC and NED Electronics developed a low-power low-noise all-digital phase lock loop (ADPLL) LSI targeted to be employed in midget wireless equipment yielding a long operation lifetime for small sized batteries.

For what has been anticipated to be the next generation of wireless technology LTE is certainly gaining momentum both in terms of popularity among the service providers as well as Telecomm network equipment manufacturers around the globe. Offering a higher transmission bandwidth of around 100mbps in comparison to current wireless technology such as WiMax and such and ease of deployment through upgrading the existing wireless infrastructure is proven to be the only viable alternative for service providers in terms of ROI. In light of this network equipment manufacturers are gearing up their product development roadmap to accommodate the service provider’s ambitious time table of LTE deployment. Read more

Development of Enhanced Femtocell Base Transciever station by DoCoMo

July 7, 2009 · Filed Under Trendy Products · Comments Off on Development of Enhanced Femtocell Base Transciever station by DoCoMo 

DoCoMo announced the development of a compact indoor base transceiver station or otherwise referred to as femtocell BTS. The newly developed femtocell BTS supports extra fast data communication according to DoCoMo. The newly developed femtocell BTS is compatible with High Speed Packet Access (HSPA) technology which is an integration of HSDPA (downlink) and HSUPA (uplink) giving a boost in the upload speeds. The newly introduced DoCoMo’s femtocell has a best effort downlink capability of 14Mbps and uplink of 5.7Mbps in comparison to the current femtocell which offers downlink of 3.6Mbps and uplink of 384Kbps.DoCoMo introduction of femtocell is to expand mobile phone services at home as well as small offices where radio signals from DoCoMO’s outdoor base stations have a difficulty reaching the users.

Introduction of WiMAX Gateway and USB card by OKI

June 12, 2009 · Filed Under Trendy Products · 1 Comment 

Based on newly introduced WiMAX mobile broadband services by UQ Communications Inc. in Japan, OKI has introduced a newly developed WiMAX gateway with routing functionality. The newly developed gateway set will satisfy the UQ’s gateway based services allowing customers to use the UQ WiMAX services at the convenience of their home through WiFi by connecting to WiMAX network and at the same time use the WiMAX USB type UD01OK dongle for outside of home use. The WiMAX WiFi Gateway UG010K which OKI refers to it by WiWiGW has WiFi conversion functionality allowing PCs and other WiFi enabled devices such as mobile gaming devices to be connected to WiMAX network. The newly developed set will be sold through the newly WiMAX MVNO partners such as NEC’s Biglobe as of July 1st, 2009.
