What is the Internet of Things?
The “Internet of Things” (IoT) may sound complex, but, is a simple concept to understand. On a very high level, IoT is the ability for things that contain embedded technologies to sense, communicate, interact, and collaborate with other things, thus creating a network of physical objects. In recent years this concept has gained enormous momentum and is now one of themost talked about things in the world of technology today. At this rapid rate of growth, it is projected that there will be approximately 26 billion cconnected devices by 2020.
At Enextgen Wireless, we leverage on LTE as a back haul for our IoT connectivity using LTE-M.
LTE-M is the abbreviation for LTE Cat-M1 or Long Term Evolution (4G), category M1. This technology is for Internet of Things devices to connect directly to a 4G network, without a gateway and on batteries.
- It’s cheaper. Devices can connect to 4G networks with chips that are less expensive to make, because they are half-duplex and have a narrower bandwidth.
- Long Battery Life. Devices can enter a “deep sleep” mode called Power Savings Mode (PSM) or wake up only periodically while connected. That mode is called extended discontinuous reception (eDRX).
- Service Costs Less. Because the maximum data rate of LTE-M devices is only about 100 kbits/s, they do not tax the 4G network as much. Carriers can offer service plans that closer to old 2G M2M pricing than 4G pricing.
