Current OpenAirInterface.org software requires Intel architecture based PCs
for the eNB or UE targets. This requirement is due to optimized DSP functions
which make heavy use of integer SIMD instructions (SSE, SSE2, SSS3, SSE4, and AVX2).
The software has currently been tested on the following processor families:
Generation 3/4/5/6 Intel Core i5,i7
Generation 2/3/4 Intel Xeon
Intel Atom Rangeley, E38xx, x5-z8300
For the UE it has been tested with :
Intel® Core™ i5-6600K CPU @ 3.50GHz × 4
Intel® Core™ i5-6600 CPU @ 3.30GHz × 4
Intel® Core™ i7-8700 CPU @ 3.20GHz × 6
Note: When running the software on virtualized environment (containers, VMs), make sure that the access to the RF interface is granted (e.g. passthru) and CPU flags are set. In addition, make sure that low latency kernel is installed when using VMs and that enough CPUs processing is available.
The OpenAir-CN EPC component should work on any 64 bits Linux machine. Container virtualization may not be used when using Openair-CN (as openair-cn requires to install kernel modules).
Specific hardware and operating-system constraints are required for real-time operation
using various hardware targets. Currently these targets/constraints are:
EURECOM's ExpressMIMO2 PCIe card requiring a PC with a free 8/16-way PCIe
slot. With an appropriate adaptor the card can function in a 1-way PCIe slot
or ExpressCard slot in a laptop.
NI/Ettus USRP B200/B210 USB3 radio card requring a PC with a free USB3 port.
Please verify here
that you do not use an incompatible USB chipset.
BladeRF over USB3 port.
LimeSDR over USB3 port.
Ethernet transport (IQ samples over ethernet) requires a PC with a fast ethernet
port (10G or more, eNB/RRH -> done, UE functionality under development).
UE/Sim Card Requirements

Since, LTE always operates in licensed band, we never recommend to do Over the air testing. The commercial cells nearby will always interfere with OAI and impact its performance negatively. You can also be fined by local authorities for transmitting into licensed band without authorization. We recommend using the RF cage below for testing or similar products
