PlusN Raises $600K to Maximize Spectral Efficiency of Mobile Networks
ELMSFORD, N.Y. --(Business Wire)--
PlusN, developer of a digital multi-band downlink carrier aggregation
solution, raised $600,000 to advance its commercialization efforts.
Investors Franklin "Pitch" Johnson, founder of Asset Management
Ventures, Chris Brody, chairman of Vantage Venture Partners, and John
Levy, executive chairman of PlusN, led the financing.
PlusN is preparing for the release of its Smart Carrier Aggregator™
product evaluation kit to mobile operators and OEMs later this year.
Based on state-of-the-art signal processing, the patented Smart Carrier
Aggregator combines 2 to 5 carriers in the basestation downlink digital
front end - effectively and efficiently addressing the industry's
multi-band aggregation needs and requirements. Designed for deployment
in LTE (News - Alert) and LTE-A basestations, the software-based solution is compatible
with current and planned future LTE-based mobile devices.
"With the current explosion in wireless data use, the global mobile
operator community is looking to carrier aggregation technologies to
maximize data capacity in their mobile networks," said Levy. "The Smart
Carrier Aggregator provides operators with the highest data capacity and
spectral efficiency in the most cost-effective multi-band solution
The Smart Carrier Aggregator delivers efficient and lossless
intra-band/inter-band downlink aggregation for all size basestations -
traditional, small, and pico cells - and all wideband power amplifiers.
It enables mobile operators to combine non-contiguous band,
multi-carrier, multi-technology waveforms - both in licensed and
unlicensed spectrum - in a lossless scheme that does not degrade EVM and
improves the efficiency of the original carriers in the aggregated
The Smart Carrier Aggregator is designed to operate with any industry
standard LTE or older technology mobile receiver. As such, it requires
no aggregation-specific software or chips in the mobile devices, nor any
"side communication" with the mobile devices, as many other aggregation
schemes require. This significantly reduces insertion/implementation
cost in an existing network and accelerates deployment.
"Since it's a software-based solution, the Smart Carrier Aggregator
seamlessly integrates into the digital frontend of the basestation - no
extra infrastructure or power resources are required," explained Levy.
"It can be easily deployed in both macro and small cell systems and is
compatible with 3G, 4G and beyond."
Upcoming LTE-A (or 4G+), which promises to deliver speeds that double
present-day 4G LTE, includes carrier aggregation specifications. Mobile
operators in the United States and Korea have already begun deploying
various carrier aggregation technologies with additional roll outs
expected in numerous other countries.
PlusN has developed an innovative and efficient, digital multi-band
downlink carrier aggregation solution for all basestations. The Smart
Carrier Aggregator™ delivers efficient and lossless
intra-band/inter-band aggregation of 2 to 5 carriers for all basestation
downlink transmitters that is compatible with today's LTE and emerging
LTE-A handsets. Aggregation is performed at the basestation -
traditional and small cell - improving the efficiency of the original
carriers in the process. Based on patented, state-of-the-art signal
processing techniques the Smart Carrier Aggregator™ enables mobile
operators to digitally and cost effectively combine non-contiguous band,
multi-carrier, multi-technology waveforms in a distortion-less manner.
This software-based solution is compatible with current and planned
future LTE-based mobile devices.
