The Lure of Unlimited Wireless Data – Is It Necessary?


https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhU562wBtZffvS22dQOy2Pv6tLJqmWc_B8VNNJvCn9q-YRDZuCnur6oPfl1kB5G2Kapa47gT2vQ8fQonJ5dUhc4LaEADhT2ZpHSDuJ5rgMb6llc8YP9krTeCKSHLFW3Zj3ouWLgam-LFKCE/s1600/gold-1024.jpg

Many believe that unlimited data is about the ability to do whatever you want on a mobile device while enjoying the freedom of not being required to pay extra charges. Nobody likes to think that they are restricted when they access the Internet, and we have grown accustomed to wired Internet access from home or work that doesn’t impose limits.

However, wireless connectivity is different than wired connections and more susceptible to “traffic jams” that slow down the networks for everyone. This is usually the result of too many people trying to do too much over their connections at the same time.

he quality of connection is important to wireless users, and when connections become slow or disconnections occur due to overcrowding, users become disappointed. Let’s face it, if everyone had unlimited data and used it fully, the performance of the networks would suffer because of bandwidth restrictions and the “shared resource” nature of wireless. The bottom line is: users agree that degrading the networks is something that they don’t want to happen.

Invariably, degraded networks would cause the carriers to seek upgrades to their networks to increase capacity. Much like highways that need to be widened for peak rush-hour traffic, this would require major investments that someone would have to pay for – that someone being the subscribers. In the case of highways, we often see this as tolls implemented to pay for the upkeep of roads. Wireless would follow a similar model.  Carriers are continuously investing to improve their networks, but concentrating on overall quality improvements is ultimately in the best interest of all users, unlike simply adding capacity to accommodate those who use the most data. The additional expense required for the latter would be passed on to normal users, who would have to pay for something they don’t need.

With the increased use of their devices at home and work, there is a greater likelihood that consumers will access and use WiFi to offload their high-bandwidth and data hungry apps, such as video streaming. Seated on your couch, you may well consume a 30-60 minute video, which you are less likely to do while on the road or moving about. In fact, a Mobidia Technology study conducted in November of last year found that users on Android phones consumed 6.8GB of Wi-Fi data and those with iPhones consumed 8.9GB of Wi-Fi data per month. This shows a strong correlation with users accessing WiFi for high data uses. Nevertheless, even if we combined mobile and WiFi data usage, we’d find that the vast majority of users would still be within the allotments of data plans available from the carriers at a reasonable cost, particularly if it’s a multi-device shared family plan. In most cases, users are very well served by current wireless data plans, and really don’t require more.

So, while unlimited data may sound attractive, there is no practical effect of data limits on the majority of users. Understanding this should bring rationality to a discussion that is often held on a “gut feeling” level. Keeping adequate speed and performance while allowing all users to share the limited commodity we call wireless data is the fair way to deal with wireless connectivity. And ultimately, that is what is beneficial for wireless consumers.

4 Ways Super Batteries are Going to Change Everything

When you see stories that talk about batteries that last forever, you may think, “Great, I’ll never have to charge my phone again.” But there’s so much more to it than that.  Some big things are happening in batteries that promise to change everything.

A team from Graphene 3D Labs has spent over five years designing a material that can be 3D printed into a functioning battery. It conducts electricity 30 times faster than silicon, and based on various designs, could print batteries for multiple applications on the fly.

Across the globe at Nanyang Technological University, a team of researchers has developed a lithium ion battery that can charge up to 70 percent in just two minutes, and will last for over 20 years. They use titanium dioxide nanotubes instead of traditional graphite, which speeds up the battery’s chemical reactions.

Yet another team, this time from Ohio State University, is working on a solar battery. This eliminates the loss of electricity that happens when the solar cell and battery interact, and enables the battery to continuously charge from free, limitless solar energy, all while it’s in use.

These are just a few of the many experiments aiming to improve battery technology. And here’s how it’s going to change everything.

1. Super batteries are going to be a game changer for electric cars.

One of the big barriers to adoption for electric cars is the long time it takes to charge them. With new battery technology, charging your battery might look more like filling up at the pump rather than having to let it sit in the garage overnight.

2.  Super batteries are going to change life in the developing world.

In places where power grids are unreliable or nonexistent, it can be difficult to adopt new electronic technologies. Rolling blackouts are the norm in big cities, and remote farms are lucky to have access to power at all. Reliable batteries that can charge fast and last long will be a huge help.

3. Super batteries might be able to unlock environmentally sustainable power.


Solar cells have been around for decades, but the big problem with adopting solar or wind power at mass scale is that we don’t currently have an affordable way to store the energy at night or when the wind isn’t blowing. New battery tech might be able to change that.

4. These batteries could trigger drone ubiquity.

Weather drones, Wi-Fi drones, delivery drones…there are endless uses for the year’s trendiest gizmo. If equipped with the right batteries, they could conceivably stay airborne for long periods of time, allowing them to hover in place or travel long distances while collecting and transmitting data.
