Or it could be church goers on the whole have a better attitude to marriage. Like 1cor13, exposing the selfless virtues of love, and the many endorsements of sticking with the partner you have chosen.
I switch to alum crystal type deoderant years ago.
They work well and last about 2 years per stick.
That's an American problem. GSM was sparingly rolled out in the US due to the prevalence of CDMA, so reclamation of those frequencies is manageable. There are no such plans for the rest of the world, where there are hundreds of millions of GSM devices still in use.
Australia is shutting down it's 2G networks to make room for LTE.
I've been researching M2M for new products we have been developing.
The main players are
Telit (HE910 sereis), Italy
Sierra Wireless (HL6528/HL8548), Canadian
Quectel (UC20), Chinese
Gemalto EHS6, French
U-Blox (Lisa and Sara), Swiss
I'm not sure if there is even a USA company that plays in this space.
All the modules are of similar sie but have incompatible footprints.
Essentially, these modules will embed a Broadcom SOC and a custom OS. Broadcom was charging the module makers too much, so they have started moving to Intel and others. These product cost mega bucks to develop, and even after you buy a module with all the R&D done, you still need to spend a another $60k in certification if you want to get it on the AT&T network (per product).
There is going to be a lot of growth in this area as people develop IoT gateways. (as we are doing)
It's still modulation, modulation creates sidebands, and sidebands require bandwidth.
Nothing has changed, the Shannon–Hartley theorem still rules.
It's not modulation, it's multiplexing using a constant angular momentum. Modulation requires a change in something. With this case the they are sending seperate radio streams using different but constant rotated angluar momentums.
Think of it like 3D glasses in movie cinema that use right and left hand polarised light.
Got to agree. We use a cyberoam appliance and ssl VPN. Does all firewall and av duties as well as VPN.
In OZ, the carriers block at the IMEI level, so if a phone is stolen you can't use it in Australia (unless you can change the IMEI to one that the carriers recognise as valid)
Why doen't the USA do this as a sterting point?
One reason I turfed my backyard with artificial turf.
I was sick of weeds, animals digging in it, mowing it, fertilizing it, the kids trampoline killing it.
Synthetic grass can now look as good as the real deal. It can get hot in summer, but otherwise its nice having an always perfect looking lawn.
NO mine wants a tailings dam to collapse. There are regular conferences on how to design the things and specialists who design them. NO CEO wants this to happen, because the cost reparations is horrendous, and contrary to what the comments have been like here, the bosses of these companies (well the ones I've know of) want to be good corporate citizens.
Mining has risks, and incidents like this will ne analysed and fed back into the future design models, and like all things in life, will improve over time.
We use it for GUI interface in industrial controllers.
Have never like tek scopes that much, or Agilent. In fact my fav. Scopes are Yokogawa DLM series.
All the manufacturers do the cripple thing though. If you want free I2C or LIN or CAN or USB or UART, buy a PC scope like a CleverScope.
To add to what you said.
Australians now pay about 25c/kwh compared with 12c/kwh 10 years ago.
The overinvestment in wires and poles was due to stupid legislation that GAURUNTEED a 10% return on any capital investment. (Gee lets spend a billion so we gaurunteed to make $100M)
We put 40kwh of solar in at our business that with the current subsidies nets us 18% return on capital (vs 2% cash in the back)
Not sure where you got $6k from.
We have a Yamaha & Juki machines and they cost between $60k and $120k new + feeders.
For $6k you get somthing more like this.
I had a debt collection agency come after our business for $100 unpaid cell phone bill.
It was from a lone disused cell phone where we had either never received the invoice or admin had misplaced it.
I said no problems, just give me a copy of the invoice and we'll pay up.
They said. Can't do that.
To cut a long story short, the phone company sells anything past due date to a collection agency BUT doesn't bother to give them the supporting documentation.
How retarded is that!
We are about to embark on designing a similar product. Essentially we want a gateway that can select from either a Cell Phone embeded data modem such as the Telit HE910, or local WiFi, then provide an internal data link via USB or Ethernet to our device and some remote connectivity for setup via Bluetooth.
We need good power management, and the ability to add local peripherals (such as a keypad, status LEDs, etc)
OpenWRT looks like the right foundation, but which chipset to select is more difficult.
Any suggestions from hardware devs out there?
