Wireless Networks
In the past few years, we have seen an explosion in the Internet of Things (IoT) applications and connected products such as wireless sensors, smart meters, home automation devices, alarm systems, and wearables. Wireless connectivity is at the heart of IoT.

Types of Wireless Networks:

The most regularly used ISM band is the 2.4 GHz region which is used for WiFi and other protocols. These wireless standards (Like WiFi, Bluetooth, or ZigBee) are popular in both chips and integrated modules which you can design into your new IoT device.

Designing at the chip level provides great flexibility to the IoT designer, who can choose the latest ICs with only the features and performance needed for the IoT device.

 Wireless networks

1. Wireless Wide Area Networks (WWAN)
2. Wireless Local Area Network (WLAN)
3. Wireless Personal Area Network (WPAN)

1. Wireless Wide Area Networks (WWAN):

A WWAN is a network that covers a large geographic area, like, for example, a mesh network. A WWAN is transmitting tiny packages of information between devices, mostly through sensors.

A WWAN is using mobile telecommunication cellular network technologies such as LTE, GSM or cellular digital packet data (CDPD) to transfer data. These technologies are offered regionally, nationwide, or even globally and are provided by a wireless service provider. Such a technology can enable users to connect to the internet or a virtual private network (VPN) within the range of a telecommunication service provider. Multiple computers come with an integrated WWAN capability.

2. Wireless Local Area Network (WLAN):

WLAN are wireless networks that use radio waves. The backbone network usually uses cables, with one or more wireless access points connecting the wireless users to the wired network. The range of a WLAN can be anywhere from a single room to an entire campus.

Every component that connects to a WLAN is considered a station and falls into one of two categories: access points (APs) and clients. APs transmit and receive radio frequency signals with devices able to receive transmitted signals; they normally function as routers.

Among others, a computer or a cell phone can be on a client side. The stations communicate through basic service sets (BSSs). Independent BSS (IBSS) exist when two clients communicate without using APs, but cannot connect to any other BSS. These are called a peer-to-peer or an ad-hoc WLAN. The second BSS is called infrastructure BSS. It can communicate with other stations but only by using APs.

Wi-Fi

Wi-Fi is widely correlated to wireless networking as it has become the standard for home networks and public hotspot networks. The benefits of Wi-Fi is that it runs over longer distances but in carefully controlled environments. The protocol is limited to work within single residential or commercial buildings and outdoor areas within short range. Wi-Fi speeds are also lower than for some other wireless protocols. Almost every mobile devices support both Wi-Fi and LTE.

3. Wireless Personal Area Network (WPAN):

Wireless personal area networks (WPANs) connect devices within a small area, somewhere around within a person's reach. A WPAN has a typical range of about 30 feet. They are commonly used to interconnect compatible devices near a central location, such as a desk.

Wireless Network Technologies carrying over WPAN:

1. Bluetooth radio
2. Bluetooth Low Energy
3. ZigBee
4. Z-Wave
5. Thread

With billions of wireless devices on the air already, and many billions more projected to join them in the next few years, many radio frequency bands are becoming crowded, and interference is a growing problem.

In some environments (such as some hospitals), new PAN devices are simply not expected to work well due to interference, so a selection of spectrum for your new product should include this consideration. You should consider this when designing your next product.

LTE

Before newer smartphones came out with the fourth-generation wireless network (4G), phones employed older cellular communication protocols like HSDPA or GPRS. Industry leaders invested large amounts of money to upgrade the network equipment to support 4G. 4G LTE stands for “fourth-generation long-term evolution,” where LTE is a type of 4G what provides fast connection and the best user experience.

Proprietary

Proprietary is a custom protocol that is owned by an individual or a company. It is the exact opposite way of building a wireless network than an open source technology.

Owning a protocol gives the ability to have a more secure and reliable system that fits the owner's needs.
