Wi-Fi Array
8 Introduction
Why Choose the Xirrus Wi-Fi Array?
The deployment of wireless LANs is becoming increasingly common as
businesses strive for greater flexibility in the workplace and the need for
employee mobility rises. The only requirements for an effective wireless
deployment are a power source, a couple of screws, and a little imagination.
Wireless LAN is also fully compatible with standard Ethernet protocols, so
connectivity with existing wired infrastructures is transparent to users — they can
still access and use the same applications and network services that they use
when plugged into the company’s wired LAN infrastructure (it’s only the plug
that no longer exists).
Wireless LAN has come a long way in the past few years and now offers the
performance, reliability and security that Enterprise customers have come to
expect from their networks. The technology is being driven by four major IEEE
standards:
802.11a
Operates in the 5 GHz range with a maximum speed of 54 Mbps.
802.11b
Operates in the 2.4 GHz range with a maximum speed of 11 Mbps.
802.11g
Supports a higher transmission speed of 54 Mbps in the 2.4 GHz range
and is backwards compatible with 802.11b.
802.11n
Uses multiple antennas per radio to boost transmission speed as high as
300 Mbps, increasing throughput, range, and maximum number of users.
802.11n is backwards compatible with 802.11a/b/g.
Whether you have just a handful of users or thousands of users, wireless has the
scalability and flexibility to serve your needs.
