The difference of DLNA and Bluetooth Audio
Solutio
n
Feature
DLNA Bluetooth
Transmissi
on medium
Operates through regular
network, can be any kind of Wi-Fi
or Ethernet. Wi-Fi is 2.4GHz with
rates reaching 150MBits/s
(802.11n 1T1R capable on DLNA
module).
RF 2.4 GHz only
Transmissi
on distance
No limit. As soon as there is a
network (can be mixed, Wired
and Wireless) DLNA can
operate. If we take the most
simple connection : Regular
Wi-Fi Access point + DLNA
module, the in house range can
be easily 30 to 40m even with
walls between both devices.
Several meters depending on
the Bluetooth
transmitter/receiver RF power.
Stops working as soon as one
wall is between both devices.
Audio quality becomes very
poor with distance.
Power
Consumpti
on
DLNA module total average
power consumption during
operation (Wi-Fi connected and
Audio playing) is less than 1W.
Connected idle mode power is
around 700mW.
Depends on the Bluetooth IC,
comparable with Wi-Fi.
Audio
quality and
Parameter
Allows all audio CODECs,
sample rates from 8KHz to
96KHz and audio resolution up
to 24 bits. Lossless audio
formats are compatible with
DLNA. All playback information
is exchanged (Title, Artist, Album
Artwork, Duration, …)
Fixed SBC or MP3 CODECs
depending on both devices
common capabilities. Lossy
audio formats, and worse,
transmission delay is introduced
due to streamer/receiver
distance and link quality
calculation.
Other
points
--Allows discovering Music on
network DMS (PC or NAS),
internet music content such as
web radios or premium music
content.
--Allows DMR/DMS
simultaneous discovery and use
from several devices (DMC)
--When you turn off you phone or
leave the room or receive a call,
--Only shares the content from
the phone to the Bluetooth
system. Only one simultaneous
connection allowed.
--When you turn off you phone
or leave the room or receive a
call, no more music playback
possible.
