Nokia Siemens Networks is introducing new Micro and Pico base stations for LTE and Wi-Fi designed to complement standard base station capacity in hot zones - areas of high subscriber density. The new Micro and Pico bases stations can be integrated into the company’s Flexi Zone architecture for mobile traffic hot zones.
Nokia Siemens Networks’ Flexi Zone supports up to 100 access points per hot zone while operating as a single base station from the network’s point of view.
NSN said the unique architecture of Flexi Zone helps manage interference and significantly reduces the core network and maintenance demands of large small cell deployments while addressing street level challenges. The compact next generation Flexi Zone Micro and Pico can be operated as stand-alone base stations initially and then evolved into Flexi Zone Access Points in a Flexi Zone architecture, as hot spots grow into hot zones from areas covering a few cells to large indoor spaces like shopping malls and airports.
At next week's Mobile World Congress, NSN is also introducing new HSPA+ and LTE Femtocells for small cell coverage in enterprises and indoor public areas. The two new products feature plug-and-play deployment and provisioning to enable rapid ramp-up of new services, tap into new revenue streams, and capitalize on value-added enterprise services. The FAPe-hsp 5620 Femtocell for HSPA+ offers high output power for large coverage, while the FAPe-lte 7610 is the company’s first Femtocell Access Point for LTE.
The company is also enhancing services for Heterogeneous Networks (HetNets) to include customer experience management capabilities to analyze traffic hotspots and ensure backhaul capacity. Services for HetNets includes hotspot analysis, optimization and small cell planning and deployment to help operators optimize their mix of macro and small cells. It now provides customer experience management capabilities to help operators understand the effect of traffic hotspots on the end user experience.
"To support the dramatic growth in mobile broadband demand, operators will need to significantly increase capacity in high-traffic areas by adding small cells that complement their macro network. Our complete small cell portfolio comprises a package of products and services to combine macro and small cells to provide the best coverage and capacity in all locations," said Bill Payne, head of the small cells business, Nokia Siemens Networks. “With these launches, we are extending our industry lead in small cells by offering a complete portfolio across both macro and small cell technologies that delivers the best return on operator investment.”

The new processors combine up to 16 ARM Cortex-A15 cores with LSI specialized networking accelerators to optimize performance and power efficiency. On-chip network accelerators deliver up to 50 Gbps packet processing, 20 Gbps security processing and 160 Gbps of Ethernet switching via 16 10G Ethernet interfaces. LSI plans to offer several versions with different core counts and throughput capabilities. The chip design leverages ARM’s CoreLink CCN-504 low-latency interconnect in 28nm process technology.
The picocell base station design integrates a Freescale BSC9132 multi-core baseband processor and Maxim MAX2580 small cell RF transceiver to deliver LTE/3G coverage with 1W+ antenna output. The LTE/3G picocell brings together a Freescale BSC9132 base station SoC card, a Maxim MAX2580 RF transceiver card, RF power amplifiers, and network management cards—all in a passively cooled enclosure and weighing in at 6.8kg.
