Symbian Series 80 Platform Ad Hoc Communications over WLANs |
|
 Many Symbian OS developers already know about
ad hoc networking using the Bluetooth APIs, but now they have a new
option: ad hoc networking over wireless LANs (WLANs). Using WLANs
offers a transmission distance of up to 100 meters -- 10 times farther
than that of Bluetooth connectivity. And as the base of smartphones and
Series 80 devices expands, developers will find that the market for
WLAN-capable, Symbian OS phone applications is growing, too.
{mosgoogle}As a rule of thumb, WLAN best suits
applications that need both high data-transfer rates (up to 11 Mbps)
and access to an existing network. Bluetooth technology, on the other
hand, is best for applications that use short, noncontinuous
connections to other devices. This is due to the better device and
service discovery of Bluetooth technology, an important advantage when
mobile devices are randomly searching for other devices. WLAN access,
however, offers more network flexibility. On a WLAN, the network
connection is defined by the application developer, while a Bluetooth
connection can only be a master/slave setup.
