Low Power: Requires minimal energy, with prolonged battery life of up to 10 years, minimizing battery replacement costs

Secure: Features end-to-end AES128 encryption, mutual authentication, integrity protection, and confidentiality

Standardized: Offers device interoperability and global availability of LoRaWAN networks for speedy deployment of IoT applications anywhere

Geolocation: Enables GPS-free tracking applications, offering unique low power benefits untouched by other technologies

Mobile: Maintains communication with devices in motion without strain on power consumption

High Capacity: Supports millions of messages per base station, meeting the needs of public network operators serving large markets

Low Cost: Reduces infrastructure investment, battery replacement expense, and ultimately operating expenses

3. Application Areas

Some companies are using the full LoRa technology stack in interesting ways. Ofo, a Chinese bike sharing company, is equipping its bicycles with LoRa devices and wireless radio frequency technology to pinpoint the bikes’ locations. The company currently operates in more than 180 cities in China.

With a multitude of IoT vertical applications, LoRa Technology is creating business efficiencies and improving lives around the world.

Global System for Mobile communications

1. Introduction

GSM (Global System for Mobile communications) is a standard developed by the European Telecommunications Standards Institute (ETSI) to describe the protocols for second-generation digital cellular networks used by mobile devices such as tablets.

2. Features & Specifications

The uplink frequency range specified for GSM is 933 – 960 MHz (basic 900 MHz band only). The downlink frequency band 890 – 915 MHz (basic 900 MHz band only).

Channel spacing indicates the spacing between adjacent carrier frequencies. For GSM, it is 200 kHz.

Duplex distance is the space between the uplink and downlink frequencies. The duplex distance for GSM is 80 MHz, where each channel has two frequencies that are 80 MHz apart.

The total symbol rate for GSM at 1 bit per symbol in GMSK produces 270.833 K symbols/second. The gross transmission rate of a timeslot is 22.8 Kbps.

GSM is a digital system with an over-the-air bit rate of 270 kbps.

3. Application Areas

GSM is recommended for industrial industries.

Useful for digital communication such as GPS, SMS, voice calls and more.

IEEE 802.15.4-based specification for a suite of high-level communication protocols.

1. Introduction

Zigbee communication is specially built for control and sensor networks on IEEE 802.15.4 standard for wireless personal area networks (WPANs), and it is the product from Zigbee alliance.

2. Features & Specifications

Zigbee is built for control and sensor networks on the IEEE 802.15.4 wireless standard for wireless personal area networks (WPANs). The Zigbee WPANs operate on 2.4 GHz, 900 MHz, and 868 MHz frequencies.

The Zigbee specifications, which are maintained and updated by the Zigbee Alliance, boost the IEEE 802.15.4 standard by adding network and security layers in addition to an application framework.
