Bryan and Wendy,
Yes, you can connect bridge type devices like the bullet to a wireless router and get wireless on board.
An alternative is to go with a repeater WiFi
unit which once it is setup will repeat the hot spot or access point locally. We use a repeater on our boat. The advantage of the repeater is that it has the same high power for repeating which is more than the typical wireless router, you have only one device, your power consumption
is less than half and you only have to setup one device. The only downside which will not really apply is that the radio
is shared between communication to the hot spot and the client which halves the available bandwidth. As the bandwidth is 54 Megs, half is way more than you would ever get from a hot spot.
Regarding "ease of use". If you go for the bullet and a wireless router, check that you are able to setup and scan for hot spots on the bullet via a computer connected via wireless or directly to the router. I have ordered a bullet for experimenting with but it appears that they will only be available sometime this month so I can't answer, maybe Bob can.
The repeater I use has a simple scan web page where I scan and select a hot spot and then the unit remembers the hot spot and connects automatically whenever it is turned on. The interface is designed for the typical user rather than a networking professional. You do have to be physically connected to the unit for doing the scan, but once setup you are fully wireless. The power uses the same cat 5 cable with PoE.
Regarding power consumption
. PoE is great. With either the bullet or a repeater I suggest a PoE injector rather than a hack. Injectors are are low cost. Look for a wireless router or repeater that can take 12V DC and is not a power hog. Some Engenius units will take 12V DC. The repeater I use is designed "Green". It takes anything from 9.5 to 48V DC and uses 4 to 8 watts. Commercial
wireless routers can run pretty hot depending on their power. For land applications 4 watts or 25 watts makes no difference. For me on a mooring
the difference matters. Also the heat has to go somewhere and confined heat will limit electronics
Choose your equipment
carefully. For the same reason you may have a marine
grade stereo system rather than a car system on your boat, understand that land grade electronics
can have a limited life in a salt environment
. So for indoor parts
, look for or add a conformal coating or depending on your use, be prepared to replace periodically. For outdoor components mounted permanently, look for truly waterproof with some sort of standard. NEMA6 or IPX7 is great especially if you have stuff permanently installed outside. Being European you may be more familiar with IEC 60529 IPX7 which is similar but a little less stringent than NEMA6.
An IPX7 designation means the case can withstand accidental immersion in one meter of water for up to 30 minutes
. NEMA6 is similar but up to 6 feet.
Really useful when you get pooped with the unit on the rail or with wind
And regarding your question about power from a router. I know of no router that provides power on the ethernet cable. You must use an Injector. Many wireless routers will take power from PoE, but make sure that they will accept 12V. Many require 48V which means an inverter
and power supply and subsequent losses.
Finally being in the UK and sailing in the Med. Having lived in the UK and the med and visiting often, I have experience with US products that often do not port well to other places. If you stick with 12V DC you are OK with the power. Do be aware that the WiFi
channels outside the US are somewhat different, so make sure that all routers, bridges and repeaters have a country setting that is easily accessible so you can setup for where you are. It can make the difference between connecting or not as well as fines or confiscation by the local telecom police.
Finally, as I have said in other posts, be prepared to read and learn if you use devices designed and documented for pro's with network experience. Such devices have limited support and even in the rare case that telephone support is available, it will be expensive from Turkey
Hope that this helps.
