Apple limits location-aware ads in iPhone apps

Apple has warned iPhone developers against using the device's location awareness exclusively for delivering targeted advertising.

Like a growing number of mobile devices, the iPhone knows where it is. And that can be handy for a variety of applications.

But Apple has warned developers against using iPhone OS's Core Location framework primarily to deliver location-based advertising.

An announcement in the iPhone Dev Center states that location-awareness should be used to provide "beneficial information."

Developers who make their primary use of Core Location to deliver geographically targeted advertising are warned that "your app will be returned to you by the App Store Review Team for modification before it can be posted to the App Store."

So there's still no problem with funding free apps with advertising (or subsidising paid apps the same way). All Apple's saying is that if an app doesn't have significant location-based functionality, it can't deliver location-based ads.

But some people seem unhappy with the ruling - please read on.

Some commentators have speculated that the warning indicates that Apple wants to restrict iPhone location-based advertising to its Quattro Wireless operation.

Unless you're particularly fond of conspiracy theories, a more plausible explanation is that Apple doesn't want iPhone users to get into the habit of blocking Core Location.

Core Location only works after the user has given permission for that particular app to access location information. If iPhone (and, in the coming months, iPad) owners started noticing that granting permission merely resulted in the appearance of geographically-localised ads, they may routinely deny such requests.

The privacy minded will probably do so anyway ("Let some advertising company see where I go and potentially determine where I live and work? No thank you!"), but Apple wouldn't want that spreading to The Rest of Us.

Firstly, location is a key part of some mobile applications and a lesser, though still important part of others. If people don't feel they can trust Core Location, the user experience will be degraded.

Secondly, Apple does have a financial interest (Quattro Wireless) in delivering mobile ads according to location and other criteria. Any user reluctance to allow apps to read the device's location works against that interest.

And thirdly? - see page 3.

Thirdly, Apple didn't say "If your app uses location-based information primarily to enable mobile advertisers other than Quattro Wireless to deliver targeted ads based on a user's location..."

So Apple's prohibition on using Core Location primarily to deliver location-specific ads appears to be as much in its customers' interests as its own.

Now’s the Time for 400G Migration

The optical fibre community is anxiously awaiting the benefits that 400G capacity per wavelength will bring to existing and future fibre optic networks.

Nearly every business wants to leverage the latest in digital offerings to remain competitive in their respective markets and to provide support for fast and ever-increasing demands for data capacity. 400G is the answer.

Initial challenges are associated with supporting such project and upgrades to fulfil the promise of higher-capacity transport.

The foundation of optical networking infrastructure includes coherent optical transceivers and digital signal processing (DSP), mux/demux, ROADM, and optical amplifiers, all of which must be able to support 400G capacity.

With today’s proprietary power-hungry and high cost transceivers and DSP, how is migration to 400G networks going to be a viable option?

PacketLight's next-generation standardised solutions may be the answer. Click below to read the full article.
