If you are not actively involved in the telecommunications market you might be puzzled by the term femtocell. Sound like a bio-engineering term, or maybe a novel type of memory? Not even close. Essentially, it is nothing more than a small cellular base station which connects to a service provider’s network via a broadband internet connection. It is capable of simultaneously supporting a few mobile devices, and as such is mostly targeted at the small business and residential markets, where it can extend indoor service coverage. Femtocells are of quite some interest to mobile operators, who are always looking at extending the reach and capacity of their networks. Additionally, Forward Concepts is projecting a compound annual growth rate for femtocell based equipment of 126% over the next four years to $4.9 billion in 2012.
Where there are hot emerging markets and problems to be solved, you can always count on startups appearing to tackle them, such is the case with Percello. Founded in 2007, Percello is a fabless semiconductor company based out of Herzliya, Israel that specializes in digital baseband solutions for the 3G/HSDPA/HSUPA/HSPA+/LTE femtocell markets. Earlier this month, the company raised $12 million in Series B funding from Granite Ventures and Vertex Venture Capital which will be primarily used to finish the development of the PRC6000 Digital Baseband Processor for the UMTS femtocells.
The PRC6000, is Percello’s first chip in the Aquilo Family, which integrates all UMTS baseband functions on a single piece of silicon. The Aquilo architecture combines several programmable cores with dedicated accelerators and, according to the company, Aquilo chips can be cascaded to linearly increase the maximum number of concurrent users. As for the PRC6000, from previous press-release we know that Percello licensed the MIPS32 24Kc Core from MIPS Technologies in July. The 24Kc is a synthesizable core that runs at a clock speed of at least 700MHz in a 65nm process. Additionally, Percello also licensed the Ceva TeakLite III 32-bit DSP earlier this month, which runs above 550 MHz in a 65nm process. As such, it can be assumed that the PRC6000 is a combination of these two, in addition to whatever else Percello decides to integrate onto the die. It will support up to 8 simultaneous users and has a coverage radius of approximately 500m. Mass production is expected to begin in the first half of 2009. Additional PRC6000 specification can be found here.
The company founders Shlomo Gadot, Yoav Volloch, and Rafy Carmon are all ex-LSI Logic, and beforehand were with Agere which was acquired by LSI in 2007. As such they have quite a bit of experience with SOCs, nevertheless they will have their work cut out for them for as the market for femtocells takes off, many of the established players in the baseband market are likely to either adapt their solutions to this new segment or will go on acquisition sprees.
