equipped with 802.15.1. 802.11 communicates on fixed channels and
requires manual configuration to minimize the interference among WiFi
devices in the environment. OTOH, a series of Bluetooth APs can easily
maximize the utilization of ISM bandwidth without any user
intervention -- assuming the FHSS selection among devices is uniformly
distributed. (Don't need to mention that with v3.0, 802.15.1 is on par
with 802.11 in terms of range and transmission rate.) What's the
reason behind this dilemma? Even google'ing for "Bluetooth ADSL modem"
doesn't return anything useful. Am I missing something?
i'm working on adding sharing support to my iPhone app. Right now, I'm using Bonjour to create plain TCP connections over a wifi network. This works great, except that it turns out that many wifi networks in the real world (for example, those at Starbucks and other chains) forbid Bonjour publishing and discovery over their networks.
So that limits the usefulness of sharing, since one of the use cases we imagined was that people could bump into each other where wifi was available and seamlessly share data with each other.
Is Bluetooth a viable alternative for this? We're sending large amounts of data (PNG images) over the wire, so latency and throughput might be one issue.
(I'm also interested in any other ways to make it easy to transfer data between two iPhone apps)
