Wireless (wifi) Hardware Vendors,Configuration,Price,choice,
Objective • What is your budget, including maintenance budget • Design of network • Selecting wireless products on need • Price wireless products • Legal considerations to used the frequency at your locality
Agenda • Benefit • Selecting standard and hardware • Types of Wifihardware • Features to consider • Some recommended Products
Selecting standard and hardware • What do you want to do? • Usage of your network, expectations, user stories • For example: are you building infrastructure or reaching end users?
Selecting standard and hardware • Robustness • Indoor & outdoor • Power consumption • Environment • Short & long links
Legal considerations • Regulations, licensing • standards, frequencies, applications e.g. VoIP • What equipment is available and serviced?
WiFi standards • WiFi Standard Frequency Band Maximum data rate • 802.11a 5 GHz 54 Mbps • 802.11b 2.4 GHz 11 Mbps • 802.11g 2.4 GHz 54 Mbps • 802.11n 2.4 GHz, 5 GHz, 2.4 450 Mbps
Different Types of Vendors • Mikrotick • Ubiquiti • Cisco (linksys) • Buffalo • Senao • Engenius • And more
Linksys WRT54G(L) • Type: Wireless Router 802.11b/g • Still one of the best low cost devices • GNU/Linux firmware and a great variety of firmware choices OpenWRT • Great for mesh networks • Great for experiments and training • Quite robust
MikrotickRoutres • Mikrotik Rb433, • Rb411, • Rb133 • Rb153 • Rb600 • Cross Road • Etc
