WIFI Access
Points
Using
WIFI Enabled Phones? Desktop phones are starting to come with
WIFI connectivity, Softphones on smart phones or tablets either
have to get internet from 4G connections or your WIFI network,
Softphones on PC and MAC are going to use the WIFI if that's how
the desktop is connected.
There are two big issues with VoIP over WIFI than need to be overcome
when utilizing WIFI for your VoIP devices
QoS at the WLAN
All SOHO and most Enterprise Access Points have a higher throughput
on the LAN side of the Access Point (the part that is wired to
the network) then they do on the WLAN side of the access point
(the part that your WIFI clients connect to), the result is a
bottleneck at the WLAN that can severally effect quality of phone
calls.
Aruba Networks access points have a unique QoS by SSID, this brings
QoS to the WLAN side of Access Point
Access Point roaming for Mobile users
SOHO Access Points do not allow for proper Roaming and Most Enterprise
Access Points don't manage roaming clients very well, at least
not well enough for clients that are engaged in real time streaming
applications like VoIP. They have a tendency of making "sticky
clients" where the Access Point you are on try's to hold
on the your client until the last possible second, resulting in
progressively worse call quality until the roaming swap with another
Access Point sometimes the connection is so bad before the "swap"
that calls drop, in an effort to fix this issue some manufactures
started bouncing clients as quickly as possible between Access
Points causing problems on the opposite of the spectrum, the client
devices don't know what access point they are supposed to be talking
to and massive packet loss results in very poor call quality.
The cell phone industry saw these exact same problems many years
ago, Aruba studied the issue and the proven solutions used in
the cell phone market and though its patient technology brings
cell phone roaming technology to the WIFI market.

Branch
Offices and Remote Workers?
Need
those workers to be tied in to your corprate network not just
on the same phone system? need the whole setup to be secure? with
an Aruba Controller based system that could be as easy as installing
a controller at your main office and mailing remote offices or
workers a RAP-3, RAP-100 or RAP-155 for instant WIFI and LAN connectivity
just like your workers are sitting in the main office
