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

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)
