Lesson #1: Knowing your G’s


Keeping up with mobile phone technology can be baffling, especially when we hear terms like 3G or 4G being thrown around. What does it all really mean? How many Gs do you need to make a phone call, surf the web, or download a video?

The G actually stands for Generation and refers to the evolutionary stage of mobile telephony capabilities. Here’s how it works:

First Generation (1G) was an analog cellular service that was introduced in the late 1970s. It was capable of completing phone calls but could not offer data services. It was also very susceptible to delays due to overcrowding of channels, since they could only handle one call at a time.

Second Generation (2G) was a digital service that could handle multiple phone calls per channel. The initial deployment of 2G services also included new features such as the ability to send short messages (SMS) or send photos along with messages (MMS). Later operators layered on data capabilities for basic jobs like checking emails etc., but data rates were very low… and slow.

Third Generation (3G) offered much faster data speeds so you could realistically surf the web and get emails with attachments. This capability led to the creation of smartphones that a large percentage of mobile operators offer today.

Fourth Generation (4G) digital service is capable of delivering amazingly high data rates, making watching a video on your smart phone or downloading huge files quite feasible.While the advancements are remarkable, there’s a catch. In the old 1G and early 2G days we only needed enough signal to allow us to make a call or support low data rates. As the service capabilities advanced, so did the demand for quality of service and ubiquitous access, including from your home. In fact, more than 70% of all mobile telephone calls and data sessions today are established indoors which happens to be the hardest place to get a good signal.

Poor signal means that no matter how many Gs your mobile network and phone has, you’ll still experience dropped calls and slow data rates. That’s where the Cel-Fi smart signal booster comes in. As an indoor coverage solution, it ensures you get every G worth of speed and quality from your mobile device.

Are you still using a 3G phone or have you made the move to 4G?
