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 Wifi hardware• 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

Ubiquiti LS2
Ubiquiti Bullet2
Radio
• XR2 Ubiquiti• XR5 Ubiquiti• SR2 Ubiquiti• R52 Mikrotick• etc
PCMCIA cards
• Disappearing from market, as most laptops, smart phones come with inbuilt WiFi
• Still interesting because of • external antenna option, for measuring / site
survey• use of old (pre WiFi) laptops• Cards with external antenna connectors
include Avaya/Orinoco/Proxim, Senao/Netgate (200 mW)
