![]() ![]() Getting Wi-Fi into a DSLR became a key consideration as it meant being able to transfer files to your laptop when on the move and the likes of Wi-Fi-enabled SD cards (such as Eye-Fi) became de rigeur. In short, it may be low power – which is great for constantly leaving the connection running and controlling your camera (alongside implementing a file transfer) – but it isn’t intended for large file transfers. The latest implementations stretch this to 24 MBit/s, but the transfer is usually achieved over Wi-Fi with only the connection negotiated over Bluetooth. Introduced in 1998, it was intended as a low-power, low-throughput technology to replace existing wired connections rather than specifically for file transfer and as a result (by the time the Coolpux P1 came out) could only manage 2 MBit/s. ![]() One way to mitigate this problem was to switch to Bluetooth as a wireless technology. ![]() Solutions to optimize this problem revolved around keeping the transceivers off most of the time and sending JPEGs to minimize data transfer. The problem with Wi-Fi – besides the issue of interference – was battery life: it literally drained away. ![]()
