SCIFI development
SCIFI (Sistema de Controle Inteligente para rede sem FIo)
is an open platform for the centralized control of wireless
networks.
It has gone through three one-year long development
phases (following the WG model):
1. the kernel, which comprises the controller and the
changes to APs running OpenWRT - prototype
2. the graphical interface and reports - pilot
3. the monitoring system – service (?)

OpenWRT
It is a Linux for embedded systems
Allows customizing the Access Points.
Opens the possibility of hardware
independence (many vendors)

The Problem with Scale
• For large networks
• Centralized management
• Automatic/centralized configuration
• Monitoring
• Solutions
• Proprietary enterprise networks

Paradigm shift
• Open source software – allows cooperative development,
adapting to local needs
• Commodity hardware – low cost, many vendors, choice of
best cost/benefit
• Easy to install - no site-survey
o Maximize the number of APs – Low cost HW makes
that feasible and increases the bandwidth available
o Low cost APs do not support a large number of users.
Thirty is a good compromise
o Thirty users per AP allows 2Mbps for each – that is true
even for expensive (single antenna) access points

Improvements
Throughput per access point without SCIFI
Throughput per access point with SCIFI

Good Neighbor
• Aggregate throughput (respectivelly: all APs, controlled APs, not controlled
APs, each graph showing throughput without and with SCIFI)

Conclusions
• SCIFI is a low cost solution for large scale
wireless networks.
• Hardware independent (Ubiquiti, DLink,
Linksys, TPlink) – many Aps are compatible
with OpenWRT
• Easy to install o Number of APs is calculated from the number of
simultaneous users divided by 30
o Areas for escalability
o Automatic and dynamic configuration
