5.4. Overall analysis<br />
Table 5-9 is the basic information <strong>of</strong> FSUWIN, WiFly <strong>and</strong> WiBro. FSU <strong>and</strong> Taipei use the<br />
same st<strong>and</strong>ard; Taipei <strong>and</strong> Seoul belong to the same area. In technical <strong>fi</strong>eld, Taipei should use<br />
WiMax not Wi-Fi, because it is not designed for metropolitan area. Even if WiFly upgrades to<br />
the IEEE 802.11n in the future, the overall performance is not going to improve too much. It is<br />
like carrying seven people in car <strong>wi</strong>th four seats; it can work, but not very well. So the best way<br />
is to replace the system to WiMax or combine <strong>wi</strong>th WiMax. In Seoul, WiBro’s major problem is<br />
mobility <strong>and</strong> it is also the selling point. Using WiMax to cover a city is a suitable way. It is what<br />
WiMax designed for. Even though WiBro’s overall performance is not as good as expected so<br />
far, the technical issues are solvable by new devices <strong>and</strong> technologies. As for cost <strong>and</strong> service<br />
problems, it is the same road <strong>and</strong> bridge issues <strong>wi</strong>th WiFly. Both WiFly <strong>and</strong> WiBro are WISPs<br />
<strong>and</strong> the best way for them to survive in future Internet market is to integrate <strong>wi</strong>th ISPs.<br />
FSUWIN is the most successful <strong>case</strong> <strong>wi</strong>thin these three <strong>case</strong>s. In the future, after installing<br />
the central controller, OTC can easily monitor the network status <strong>and</strong> provide more reliable<br />
service. FSUWIN reached its goal <strong>and</strong> does a good job. One more factor <strong>of</strong> FSUWIN’s success<br />
is no <strong>fi</strong>nancial burden. It is not a commercial network <strong>and</strong> is supported mainly by tuition. Thus it<br />
does not have to worry about users <strong>and</strong> application issues. This feature makes its operation<br />
simpler than other two systems. In short, it is a good solution for smaller <strong>and</strong> local area.<br />
So far WiFly <strong>and</strong> WiBro are still seeking their marketing positioning. 3G, Wi-Fi, WiMax<br />
<strong>and</strong> <strong>wi</strong>red internet service where the balance point for these technologies is an important issue to<br />
industries, manufactures <strong>and</strong> researchers. Table 5-10 is the basic information for internet access<br />
methods. The service providers <strong>and</strong> WISP should not only focus on providing content but also<br />
have to think about the dem<strong>and</strong> <strong>of</strong> <strong>wi</strong>reless network users.<br />
Based on the patterns <strong>of</strong> people’s behaviors accessing the Internet, these technologies should<br />
be coexisted. Figure 5-21 is an example for using these technologies. When a man wants to go to<br />
a state park <strong>and</strong> has the Internet access all the way, he has to bring his phone <strong>and</strong> NB. At home<br />
he can use Wi-Fi to collect the information <strong>of</strong> the state park. During transportation, he can access<br />
the Internet by mobile-WiMax. And then, when he arrives the state park, he can still check his email<br />
by <strong>fi</strong>xed-WiMax service. If he wants to take a rest, he can stay in the state park service<br />
center where Wi-Fi is available. Moreover, all the way, he can make a video phone call<br />
anywhere at any time. It is one possibility for future development.<br />
WiFly <strong>and</strong> WiBro were just commercialized. They have to learn from mistakes, because<br />
they are the pioneers <strong>of</strong> public <strong>wi</strong>reless network. The technical issues they have right now are all<br />
solvable. WiBro can showed its real capacity only after the mobility is truly functional <strong>and</strong><br />
devices price is acceptable. WiFly can adopt WiBro’s technologies to improve its signal <strong>and</strong><br />
coverage issues. The <strong>wi</strong>reless city story has not <strong>fi</strong>nished yet, <strong>and</strong> WiFly <strong>and</strong> WiBro still have a<br />
chance for success.<br />
