HSUPA to Femtocell Reference Design - PC8209 - picoChip

picoChip announced the HSUPA-femtocell reference design. (HSUPA = High-Speed Uplink Packet Access). Femtocells allow carriers to compete with Voice over WiFi. picoChip’s new PC8209 adds HSUPA to company standard reference design, as used by ipAccess, Dekolink and Ubiquisys.

Example of Femtocell Implementation Using PC8209

About HSUPA
HSUPA (High-Speed Uplink Packet Access) increases the 3G physical-layer link speed to 5.76Mb/s, increasing efficiency when used in conjunction with its downlink equivalent, HSDPA (High-Speed Downlink Packet Access). HSUPA reduces network latencies and can allocate capacity to users with shorter delays and greater flexibility: essential features for real-time and response-critical applications.

PC8209 key features:

• Fully compliant with 3GPP Release 6 TS25 series standards including support for HSPDA and HSUPA
• Supports all Downlink & Uplink Transport and Physical channel types required by 3GPP FDD standards channels including HSPDA/HSUPA
• Support for up to 4 users in a 200m Femtocell, each with 1 AMR voice along with 1 HSDPA session and a shared HSUPA channel.
• Frequency and time synchronisation
• Convolutional and Turbo FEC encoding/decoding
• Supports all baseband measurements required by 3GPP Release 6 standards and OA&Mdefined hardware alarm gathering and reporting via Host Processor interface.
• Demodulation and despreading of uplink physical channels with up to 4 Rake Fingers per DCH/HSDPA user with integrated Searcher
• MAC-b support for broadcast messages over the BCH channel

The new PC8209 design combines a modem that is fully compliant to 3GPP Release 6 for four users with a 200m range, supporting 7Mb/s HSDPA and 2Mb/s HSUPA.

Major priority for mobile operators is improving indoor coverage and capacity of 3G to enable new service opportunities in the home and SOHO markets. The market requires a small plug-and-play device, to pass call traffic and signaling between the mobile phone and network.
