Basic features

IQRF is complete wireless technology for ISM bands 868 MHz, 916 MHz and 433 MHz !

- Transceiver modules with built-in operating system.

- Functionality depends on user application written in C language or ready-to-use plug-in . - Low data rate 19.836 kb/s.

- Packet oriented communication (max. 64 user bytes in RF packet) up to 56 B in 1 packet.

- No license fees !

Basic features

• Bands 868, 916, 433 MHz

• Topology full mesh with 240 hops (used in real applications), 239 nodes

• References hundreds of thousands running devices worldwide since 2008

• Protocol IQMESH®, patented directed flooding networking, secure communication,

redundant packet deliver, no need for self healing, no latency after reset, etc.

• Range 500m line of sight / 200m municipal area / 50 – 100m indoor @ 12 mW

• Power consumption Standard RX 12.3 mA

Low Power RX 170 µA

Deep sleep < 100 nA

sleep 2 µA

Unique features

• Transceiver architecture PATENTED, used in many technologies worldwide, built-in OS

• Robust routing algorithm PATENTED, directed flooding – reliably working mesh network with 239 routers

• Direct Peripherals Access PATENTED, framework for wireless networks with no programming,

easy-to-achieve interoperability, wireless integration in a few weeks

• Fast Response Command PATENTED, the fastest wireless mesh network data collection worldwide,

2bits from 240 nodes in 26s, minimal network traffic and power consumption

IQRF Ecosystem

Ecosystem

Why mesh?

• Increased mesh coverage to go around obstacles • Extended range with extra hops • The topology can withstand the high traffic • Alternative routes to get the transfer done • A broken node will not destruct the transmission • Expansion or modification can be done without disrupting other nodes

IQRF Options

Two Layers: - operating system - user application

Two Approaches:

C programming Hardware Profiles (HWP)

HWP

No programming!

Hardware Profile (HWP) is ready to use application which offers some peripherals and services

Custom DPA Handler

Need to modify?

DPA protocol

Direct Peripheral Access (DPA) is a simple byte oriented protocol used to control services and peripherals of IQMESH

network devices by SPI or UART interfaces.

DPA protocol

PDATA – Up to 56 Bytes of data can be transferred with DPA protocol, data are used as a parameter for some Peripheral Commands, as well

NADR – Node Address (2B) specifies address of each node in a network

PNUM – Peripheral Number (1B) is code of specific peripheral available

PCMD – Peripheral Command (1B) contains specific command for particular peripheral

HWPID – HW Profile Identification (2B) uniquely specifies the type (functionality) of the device
