Verizon 4G LTE wireless broadband is 10 times faster than 3G—able to handle download speeds between 5 and 12 Mbps (Megabits per second) and upload speeds between 2 and 5 Mbps, with peak download speeds approaching 50 Mbps. Cable speeds vary, but 4 to 12 Mbps are common.

Industrial Cellular Modem

Mobile workers who need always-on Internet access - and who don't want to rely on public Wi-Fi hot spots - often turn to a cellular network for connectivity, using either a 3G-equipped notebook or an external 3G modem. Now carriers are touting faster fourth-generation wireless networks as the next phase of mobile computing. But to make use of the new networks, you have to buy a 4G-capable device or modem and a new, often more-expensive service plan.

Is it worth the hassle and expense of upgrading to 4G? To answer that question, I pitted Sprint's WiMax service - the first 4G service available in the New York metropolitan area, where I live - against its 3G network in a series of real-world tests (see ). Sprint 4G: What you need As is the case with any wireless service, you need three things to get access: a network, a device for connecting and a service plan. Available in 62 cities, from Everett, Wash., to Tampa, Fla., Sprint's WiMax wireless service in the U.S. Is known as and is operated by Clearwire; it's based on the. The network provides adequate coverage on the coasts , but it's hit or miss in the middle of the country, and there are 12 states with no Sprint 4G service at all. When you can't get a 4G connection, the fallback is to use Sprint's 3G network, which is based on (Evolution Data Optimized) technology.

It's available in all 50 states, although - as is the case with other 3G networks - there are huge holes in the upper Midwest. Sprint says that over the next two years, it will fill out a national 4G network. In contrast, T-Mobile currently offers an (HSPA+) 3G network.

AT&T is also busy rolling out HSPA+ and is testing (Long Term Evolution) technology for a planned commercial 4G rollout over the next two years. Meanwhile, Verizon has just launched on a trial basis with limited coverage in 38 cities and 60 airports. The company says the network will be complete nationwide in 2013. Although it's not available in my suburb, Verizon LTE has been rolled out to some parts of the New York metro area, and I hope to test it in multiple locations soon. Sierra Wireless 250U USB modem The second part of the 4G puzzle is the connection device.

The that I used for testing weighs just 1.9 oz., connects to a laptop via a USB port, and can be folded up to less than an inch thick when not in use. The disk-shaped receiver, which measures about 2 in. Across, can rotate and swivel up and down to get better reception.

The device has a list price of $250, but it's free with a two-year Sprint contract. The 250U works with systems running, Vista or XP, or Mac OS X 10.5 or 10.6.

Setting up the 250U on my Lenovo ThinkPad W510 with Windows 7 took about 10 minutes; it connected to the network on the first try. Next: How I tested To see how Sprint's 3G and 4G networks compare, I used a Sierra Wireless AirCard 250U modem that works with both the 3G EV-DO and 4G WiMax networks. At 10 locations in New York and New Jersey, I fired up my ThinkPad W510 and connected to the 4G network. After noting the signal strength of the connection, I used Ookla's to measure latency and download and upload speeds.

Finally, I watched an online HD video and listened to an Internet radio station. I measured each result three times and then repeated the tests with the 3G network. I returned to each location at three different times over a 10-day period and repeated all the tests on both 3G and 4G networks.

I also used 3G and 4G connections on a moving commuter train and as a passenger in a car and averaged all the results together. To see how connecting with the modem over 3G or 4G affects battery life, I ran some tests back at my lab. To get a baseline measurement, I connected the fully charged ThinkPad W510 to my home Wi-Fi network, set it to play an Internet radio station continuously and timed how long the system's battery ran for. I then repeated this test three times with the charged computer connected to the 3G network and three times connected to the 4G network.

Faster is always better when it comes to internet access. This applies to not only simple browsing but also media streaming, app downloading, gameplay and video calls. It's hard enough, however, getting super-fast internet access at home, let alone top speeds on our smartphones and tablets over. Just how fast should you expect your mobile devices to be?

Part of it does have to do with the speed of your provider, like Verizon or AT&T, but other factors come into play too like your signal strength, what else is running on your device, and any, which can affect delays, video and audio calling, video streaming, web browsing, etc. You can test how fast your connection to the network is with various speed testing apps, like the speed test app available for and iOS. If you're accessing the 4G or 3G network via a computer, see. 4G and 3G Speeds Although theoretical peak speeds are only theoretical and hardly pan out in real world scenarios (due to things like latency), these are the speed requirements that a provider must abide by in order to have a connection that falls under the 4G or 3G category:. 4G: 100 Mbps for high mobility like service from a moving car.

1 Gbps for low mobility like when walking or not moving at all. 3G: 7.2 Mbps or 52 Mbps on 3G HSPA+ However, as you can see here, a from found the average, real world download and upload speeds for the four major wireless carriers in the US to be a bit different:. AT&T's 4G LTE network was found to be the fastest, with average download speeds of 18.6 Mbps and upload speeds of 9.0 Mbps. It's older 3G network, by contrast, averaged 4.3 Mbps download and 1.1 Mbps upload.

AT&T's LTE network had an 81.7% network connection rate. The maximum download speeds measured in this study clocked AT&T's 4G network at 19.6 Mbps. T-Mobile's HSPA+ network averaged 7.3 Mbps for downloads and 1.5 Mbps for uploads. So, better than 3G but 4G LTE is faster. How to Boost Your Internet Connection Keep in mind that when we say 'boost your internet connection,' we're not talking about pushing it over the maximum allowed level or creating some sort of new internet connection where there are no limits. Instead, to boost your connection just means to scrape away anything that might be making it slow so that it can return to a level that's considered normal.

If you find that your connection is slow over either 4G or 3G, there are a number of things you can do to try speeding up that connection on your side of it. For example, if you're on a computer, you can by changing the you're using so that pages load quicker (there's a list of ). Another method is to close down any other programs using the internet that are sucking away at the limited you have available.

Or, if you're on an Android smartphone or tablet,. The same concept applies to bandwidth on mobile devices too. Maximum 4G or 3G speeds are only attainable if you're not already running lots of other things at once.
