Most people use Bluetooth to connect their mobile devices to wireless speakers, smartwatches, wireless headphones, a car, and wireless keyboards. Many people think that Bluetooth only works with a WiFi or cellular connection, but Bluetooth is completely different from WiFi and cellular. The difference between Bluetooth, WiFi, and cellular networks? That being said, there are some features your mobile devices have that can only be accessed with a WiFi or cellular connection.
For example, your iPhone does not need to have a cellular network to pair with your car, but in order to answer your incoming calls through your car, your phone will need to be connected to a cellular network. A cellular network or mobile network is a type of wireless connection facilitated by cellular towers.
It can be accessed from almost everywhere, there just needs to be cellular towers nearby. Theoretically, a cell phone has enough power to reach a cell tower that is up to 45 miles away. But, with added external obstacles such as trees, buildings, and terrain, a cell phone might only reach a cell tower that is 22 miles away.
Therefore, the more towers in the area, the faster and more reliable your cellular network will be. Cellular devices will experience faster data, download, and upload speeds the better the network connection is. Most people use the cellular network for phone calls, streaming videos, and browsing the internet.
Cellular networks can also be used to broadcast WiFi signal. To do that, you can use a portable WiFi hotspot or a cellular modem.
Those devices will also need to be connected to the cellular network through a cellular provider. Even though cellular networks can be used to broadcast WiFi signal for internet use, cellular and WiFi technologies are very different.
The main difference between cellular and WiFi is that cellular devices smartphones, tablets, and portable WiFi hotpots require a data plan and cell phone towers to support internet access. Fast connectivity has also become available to these devices. Cellular Phones : These devices are at the forefront of data connectivity due to the fact that they are already connected to a communication platform GSM in South Africa.
As such their connectivity largely depends on the underlying cellular technology, leading to typically higher costs associated with connecting such devices.
However, in Japan the i-mode system has been very popular, mainly due to its low cost and the large time most Japanese spend commuting. To do: read up about i-mode, why has it not widely spread to the rest of the world?
Some cellular phones are not limited to only connecting using the underlying cellular network technology. Some made use of other medium such as infrared, Bluetooth , and WiFi. Recently, a group of cellular phones manufacturer has introduced an operating system called Symbian. It is hoped that Symbian will produced a single platform for developing applications for these mobile devices, thus resulting in new ways of using and connecting such devices.
However, these have grown into full-fledged computing platforms. The Pocket PC is one such device. Microsoft has taken the step of splitting the windows mobile platform for Pocket PC into two classes, although both are based on the same base operating system. One class of Pocket PC is a straight PDA or more accurately described as portable computer , while the other is a cellular phone with a some what higher processing power than other cellular phones, but still less powerful than its Pocket PC PDA cousins.
Each has their own pros and cons. Let's take a look. Portable mobile hotspots access the same cellular network as your smartphone. You can add them as another device on your shared data plan, or you can get one with its own data-only plan.
Data plan prices tend to be similar to the amount you spend on phones. These mobile internet devices tend to have between 10 and 20 hours of battery life. Some models serve as portable battery packs that can charge your phone or offer shared storage via a microSD card slot. Many have screens that show how much data you've used out of your monthly allotment. The specifics change depending on which model you buy. With the rollout of 5G, portable wireless hotspots can better function as your home's primary internet connection.
That's because 5G has lower latency, allowing devices to communicate more quickly with one another. This is key for gaming and VR. Some hotspots, such as 's HTC 5G Hub , can support up to 20 devices and provide enough battery life to cover a day's usage. One downside to a portable mobile hotspot is having to lug it around in addition to your phone, tablet, or laptop.
The cost of a data plan can also add up. If you're merely adding one to your shared data plan, you may be able to get by with tethering your smartphone instead.
Like portable wireless hotspots, dongles tend to come straight from a carrier. Many look like flash drives, while some look like small modems that you plug into your computer via a USB cable. Sticking one in your laptop has the effect of giving your computer a cellular radio.
It's now able to hop online via Wi-Fi or cellular data, just like your smartphone. How Portable Internet Devices Work. Ultra mobile PCs combine the portability of a smartphone with the functionality of a PC. See more pictures of essential gadgets. Image courtesy of Fujitsu. Types of Portable Internet Devices " ". Medium range: Technologies like Wi-Fi can allow a device to access the Internet anywhere from feet to several miles from a hotspot.
Long range: WiMAX, MIT and other long-range technologies can allow Internet communication up to miles from a base station or across the country as a networked service. Notebooks, like the Asus eee PC models, that open like small laptops Sliders, like the Fujitsu Lifebook U, with a keyboard that slides out from under the screen Tablets, like the Samsung Q1, with a side keyboard and touch screen.
Choosing Portable Internet Devices " ". When choosing a portable Internet device, consider range, power capability and screen size. Internet range: Consider whether mid-range Wi-Fi or long-range WiMAX would work better for you, and make sure the device you're considering has that range.
Power capability: Check the expected battery life for the device. Among the comparisons shown at UMPCportal. Screen size: While many portable Internet devices have a 7-inch screen, some have screens as large as 8. Format: Tablet, slider or notebook: It's your pick. Durability: This is hard to gauge because so many of the devices are so new. Check buyer reviews of your chosen Internet device at Amazon or other Web sites to see other users' experience.
Added functions: How do you plan to use the device? Consider whether Internet access is your primary interest, or if you want to incorporate a multimedia player, cell phone or GPS system. Price: Like anything new, most portable Internet devices aren't cheap -- and they vary considerably in price.
