Accessories A 900mhz receiver for Android 4.4?

[GideonG]

Hi Everyone!

I am wondering if anyone knows of the existence of a receiver of 900mhz frequency signals that is compatible with Android 4.4?

I recently bought a 900mhz router for my father to use (his work involves testing alarm systems and the serial data they send) but I wasn't informed that the 900mhz frequency can't be picked up by Android devices over Wifi (I'm clueless about this level of computing/networks).

According to the modem manufacturers, a serial data to USB cable could be used, however my father needs to be able to be walking around with the device, so as to trigger the detectors and check that they send the correct signals, so a wired cable isn't viable.

Sorry if this is vague, I'm feeling increasingly out of my depth here!

Thanks in advance for any help given!

Kind Regards,
Gideon

You'll have to root your dad's tablet then go over to XDA-Developers and check out this guide http://www.xda-developers.com/remove-band-restrictions-qualcomm/. I'm not sure this will work for what he wants but it's a start. Don't they make dedicated devices for that kind of work? This seems like a complicated way to achieve this goal.

The previous systems did have dedicated devices, however the new alarm system is going for the "use with mobile device" approach computing is taking. They function under the assumption that schools will integrate the system over the school wifi (thus 2.4ghz frequency). Unfortunately, due to complications, rather than doing this, they're running them over 900mhz frequency, which makes regular devices almost impossible to use without some form of 900mhz receiver, or (to my understanding) messing around with system files.

EDIT: You wouldn't happen to know of a 'dongle' or USB receiver or the like that would do the job? It's just that with my knowledge, I feel like I'd be far too likely to brick the tablet if I started messing around in the system files.

By the way, thank you so much for all your help, you're one of the few people (including support staff and such) that has actually given me the time off day, and helpful advice!
