One of the key features of WWAN is its ability to support multiple standards, including LTE and WiMAX. These standards enable fast data transfer rates and low latency, making them ideal for applications that require high-speed connectivity.

Here are some examples of WWAN technologies:

Wireless networks operate on various frequencies, which can affect their performance and range. The most common frequencies used for wireless networks are 2.4 GHz and 5 GHz.

The 2.4 GHz frequency band is divided into 14 channels, spaced 5 MHz apart, with channel 1 centered on 2.412 GHz. In some countries, like Japan, all 14 channels are available for use, while in others, like North America, only channels 1 through 11 are allowed.

The 5 GHz frequency band is also used for wireless networks, but its channel spacing is less intuitive due to differences in regulations between countries. The 2.4 GHz band is more prone to interference from other devices, which can affect signal quality and throughput.

A key factor to consider when choosing a wireless network frequency is the amount of channel separation required between transmitting devices. According to the IEEE Std 802.11 (2012), a distance of at least 25 MHz between center frequencies is recommended to avoid interference.

Here's a summary of the common wireless network frequencies:

In practice, using non-overlapping channels can help minimize interference and improve signal quality. However, the amount of channel separation required can vary depending on the specific wireless network protocol and device configuration.

Wireless Network Security is a top concern for any home or business network. The original 802.11 standard had a major security flaw in its Wired Equivalent Privacy (WEP) mechanism, which was easily exploited by hackers.

In 2001, a group from the University of California, Berkeley discovered weaknesses in WEP, allowing them to intercept transmissions and gain unauthorized access to wireless networks. This led to the creation of a new security solution, 802.11i, which was ratified in June 2004 and uses the Advanced Encryption Standard (AES).

The modern recommended encryption for home and consumer wireless networks is WPA2 (AES Pre-Shared Key), while enterprise networks use WPA2 with a RADIUS authentication server and strong authentication methods like EAP-TLS.

In 2011, a security flaw was discovered in some wireless routers with a specific implementation of the Wi-Fi Protected Setup (WPS) feature, allowing an attacker to recover the WPS PIN and the router's 802.11i password in a few hours.

In 2001, a group from the University of California, Berkeley presented a paper describing weaknesses in the 802.11 Wired Equivalent Privacy (WEP) security mechanism. This was a major blow to wireless network security.

The WEP security mechanism was so weak that it was easy for hackers to intercept transmissions and gain unauthorized access to wireless networks. Adam Stubblefield and AT&T publicly announced the first verification of the attack, making it clear that WEP was not secure.

The IEEE set up a dedicated task group to create a replacement security solution, which became known as 802.11i (also known as WPA2). This new standard uses the Advanced Encryption Standard (AES) instead of the vulnerable RC4 encryption used in WEP.

WPA2 is now the modern recommended encryption for home and consumer spaces, and it's a huge improvement over WEP. For enterprise spaces, WPA2 is also recommended, but it requires a RADIUS authentication server and a strong authentication method like EAP-TLS.

In 2009, the IEEE published a new standard to protect management and broadcast frames, which were previously sent unsecured. This was a much-needed update to wireless network security.

Some wireless routers have a security flaw that affects the optional Wi-Fi Protected Setup (WPS) feature. This flaw allows an attacker to recover the WPS PIN and the router's 802.11i password in just a few hours.

To combat this, some devices, like Apple's iOS 8 and Android 8.0 "Oreo", scramble MAC addresses during the pre-association stage. This makes it harder for hackers to track users' devices.

Here's a brief overview of some key IEEE standards related to wireless network security:

Wi-Fi users may be subjected to a Wi-Fi deauthentication attack, which can be used to eavesdrop, attack passwords, or force the use of another access point.

Wi-Fi certified devices often default to the least common denominator settings, which means they won't transmit at a power above the allowable power in any nation.

The regdomain setting is usually made difficult or impossible to change to prevent end-users from conflicting with local regulatory agencies.

Different countries define different levels of allowable transmitter power, time that a channel can be occupied, and different available channels.

Domain codes are specified for the United States, Canada, ETSI (Europe), Spain, France, Japan, and China.

In the United States, for instance, the Federal Communications Commission (FCC) regulates wireless communications, and devices must comply with their rules.

Most Wi-Fi devices are designed to follow these regulatory guidelines, but it's essential to understand the specific requirements for your area.
