6.4 Our Business Model
It is very evident that this technology is catching on like wildfire. Large companies such
as Ericsson and Airtouch (now Verizon Wireless) are joining in. We intend to refine our
product such that it’s a market leader accompanied with a killer applications package.
This would strain giants like Cisco and Nortel to pay us some heed. Eventually, we
intend to be bought over by one of the networking conglomerates.
6.5 Credits
We feel that it is important to mention people who have played a major role in seeing this
project through. We owe gratitude to Dr. Owen for bearing with us through the project.
We realize that we were definitely not the most structured people. He was instrumental in
guiding us through the initial phase of selecting our hardware and took great pains
himself in researching some for us.
We are extremely fortunate to have been served by the people at EMAC who on more
occasions than one went beyond their sphere to help us out. The sales group at EMAC
agreed to ship us a new board when they discovered that we had possibly shorted it out.
The tech-support group was extremely helpful in troubleshooting our problems. On one
occasion, their engineers spent eight hours working on one of our problems.
The list would be incomplete if we forget to include David Jeffery, our TA. He has been
an invaluable resource to us even though we ended up not using his ALSA based VoIP
application due to the difficulties mentioned in our report. He has helped us a great deal
with the sound system and the setup for the wireless LAN.
7 CONCLUSION AND REFLECTION
During the course of achieving our goal of VoIP over Wavelan on an embedded system,
we were able to come away with some valuable, albeit painful, lessons. We were so
thrilled with our choice of hardware platform with its pre-installed Linux operating
system and device drivers, a vendor who was willing to bend over backwards to
accommodate us, and a software application whose author was just a shout for help away
that we took a lot for granted.
7.1 The ALSA issue:
When we learnt that EMAC would load the drivers for the sound card on our system we
felt that a lot of our work was already done for us due to a wise choice in hardware
platform. Little did we realize that we were too premature in congratulating ourselves.
