What is FPRF?

 The FPRF is a radio frequency transceiver IC that mimics the concept of an FPGA

in the RF domain to deliver a multi-standard, multi frequency device

 The FPRF transmitter takes a digital data stream and converts it into wireless

signals, while the receiver perform the inverse operation

 The FPRF transceiver offers the capability to program key parameters like the

RF frequency, gain, and bandwidth

 All major elements within FPRF have programmable Bias circuits and could be

powered down and/or bypassed

 All major elements within FPRF could be isolated and used as individual circuits  Main features:

  • The FPRF is programmed by customers, not in the factory
  • The tools allow customers to experiment and change parameters on the fly

  • Open source adoption is increasing…
  • Myriad RF is an Open Source community founded

by Lime Microsystems to accelerate the adoption of field programmable for deployment of Open Source wireless platforms

  • Working with the open source community, Lime has

established a network of system developers that are designing hardware and deploying affordable wireless systems

  • Success of these open source platforms is made

possible by the configurability and ease of use of Lime’s FPRF

Cost of the Software Stack

ASICs, DSP and GPP+FPGA based solutions: Comparison

  • The difference between these solutions is the digital technology for the implementation of Baseband
  • Cost of Baseband is insignificant when software and deployment costs are taken into account.

  • 65% of the world’s population remains unconnected to the internet
  • Wireless access can be delivered using low cost GSM

(voice) and LTE / WiFi (data), based on:

  • Simplified commodity hardware
  • Software Defined Networks
  • Growing small cell market is well equipped to

meet the required scalability and cost

  • Relatively low site acquisition and rental costs
  • Easier network planning
  • Lower power consumption and (potentially) back haul costs
