Mobile<br />

Broadband:<br />

A Primer<br />

3G. HSDPA. LTE. If you’ve wondered what these stand for,<br />

here’s a quick guide to wireless broadband.<br />

By Art Ilano<br />

Business has gone mobile. With more<br />

professionals communicating, working<br />

on their e-mails and sending documents<br />

via portable devices such as laptops,<br />

tablets and smartphones, it’s only a<br />

matter of time before businesses begin<br />

wondering what the most optimal<br />

wireless solutions are for transmitting<br />

critical data.<br />

Here’s a rundown of mobile<br />

broadband options available in the<br />

market thus far, and what they can<br />

mean for your business.<br />

2G. Think of this as the Internet in slomo.<br />

Once upon a time, this so-called<br />

second generation (hence 2G) standard<br />

was the state of the art as far as speedy<br />

net connections were concerned, but<br />

that was way back during the time of<br />

dial-up modems (remember those?).<br />

Today, what we call 2G has actually<br />

evolved into “2.5G,” and is also<br />

known as GPRS networks. But it is still<br />

considered to be a sluggish way to<br />

get mobile internet. <strong>The</strong> plus side? It’s<br />

available practically everywhere. So if<br />

you’re just out to use instant messaging<br />

or other text-based applications, such as<br />

Facebook Messenger or Twitter, then 2G<br />

is passable. But once you start throwing<br />

in images or Instagram-type feeds, then<br />

you’re going to be in trouble.<br />

2G is available on all mobile networks,<br />

and practically all net-enabled phones<br />

will be able to access it.<br />

3G. This is the most common highspeed<br />

mobile network that’s available for<br />

commercial use. But even this so-called<br />

third generation of mobile broadband has<br />

a lot of flavors under it. Plain vanilla 3G,<br />

also known as HSPA for High Speed Packet<br />

Access, typically hits 1.7Mbps in real world<br />

speeds. That’s more than ten times the<br />

speed of 2G.<br />

A more advanced variant is known as<br />

HSPA+, or Evolved HSPA. This faster<br />

variant of 3G can reach up to 6Mbps in<br />

actual use. That’s over three times as fast<br />

as regular 3G.<br />

In many broadband modems, you can tell<br />

when a connection is HSPA or HSPA+ by<br />

looking at the light: a dark blue means<br />

HSPA while light blue means that you’re on<br />

the faster HSPA+ connection.<br />

WiMax. You may still hear about this<br />

occasionally, but let’s just say that WiMax<br />

is a slowly vanishing standard. WiMax was<br />

envisioned to be akin to Wi-Fi on a citywide<br />

At A Glance<br />

scale, using microwave transmissions.<br />

However, it is already being eclipsed by<br />

the aggressive rollout of LTE networks,<br />

and even the lone widescale WiMax<br />

service provider in the country is migrating<br />

towards LTE. One reason: WiMax can only<br />

promise high speed connectivity (up to<br />

30Mbps!) if you happen to live close to<br />

the broadcast tower. Most people will get<br />

just a middling 1Mbps.<br />

LTE. <strong>The</strong> state of the art in high speed<br />

mobile Internet connectivity, Long Term<br />

Evolution may very well be the standard<br />

in wireless broadband for years to come,<br />

offering speeds of up to 20Mbps at the<br />

moment, which is over three times faster<br />

than HSPA+. Great for all kinds of net<br />

usage, with blazing fast speeds that make<br />

your videos whiz by and huge downloads<br />

finish in a flash. <strong>The</strong> downside at the<br />

moment: it is still being rolled out, so there<br />

are still relatively few areas that support LTE.<br />

Also, so far only the top of the line devices<br />

can access LTE. But this should be rectified<br />

over time.<br />

Service Typical speeds What to know<br />

2G<br />

3G (HSPA)<br />

3G (HSPA+)<br />

WiMax<br />

LTE / 4G<br />

56kbps to 115kbps<br />

Up to 1.7Mbps<br />

(over ten times faster than 2G)<br />

Up to 6Mbps (over three times<br />

faster than plain 3G)<br />

Up to 30Mbps (in theory).<br />

More likely you’ll get 1Mbps.<br />

Up to 20Mbps<br />

Better known as 2.5G or EDGE. Available everywhere.<br />

But good only for text-based data.<br />

Pretty decent net connection. Not the fastest out there,<br />

but good enough for surfing and most net uses.<br />

<strong>The</strong> best balance of speed and availability.<br />

Sorry, think of this more as a footnote in the<br />

history of mobile communications.<br />

<strong>The</strong> fastest you can get on a commercial scale.<br />

However, not yet widely available.<br />
