3. What is FPRF Technology?

9 The FPRF Company – Ultra flexible RF solutions Confidential

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

MyriadRF Drives Open Source Platform Deployments

Myriad RF Open Source Developers

Slide 5: We have launched a

website called MyriadRF where we

publish designs, boards and design

kits for general users to pick up and

use in their projects without having

to have a deep knowledge of RF.

These type of initiatives are

on the rise and we see that the

future of electronics, particularly the

domain of RF will see a lot of

progress by enabling everybody to

come along and design some cool

products given that such designs

and chipsets are so readily

available and accessible.

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
