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

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
