Wireless 802.11ac

WiFi is an established technology that is always improving, introducing new features including faster speeds, greater ranges, and lower battery usage. These improvements will assist in meeting the rising demand for mobile data.

In comparison to IEEE 802.11n, the new 802.11ac amendment will provide three times the speed, twice the range, and a longer battery life. The aggregate and user throughputs in WLANs should be greatly increased thanks to the new 802.11ac standard. The desired user throughput is 500 Mbps or more, while the desired aggregate throughput is above 1 Gbps. The 2.4 GHz band (802.11b/g/n) and the 5 GHz band (802.11a/n) are used by current 802.11 technology.

While only operating in the 5GHz range, 802.11ac does provide backward compatibility.

This is valid for other 802.11 technologies (802.11a/n) using the same band. 802.11ac relies on a number of advancements in both the PHY and the MAC levels to reach these goal throughputs. These fresh features are part of the PHY improvements:

  • Enhanced channel bandwidth (80 MHz required, 160 MHz optional, and 80+80 MHz optional)
  • Quantitative spatial streams overall (up to 8)
  • Expanded complex modulation (256 QAM)
  • MU-MIMO (multi-user multiple input multiple output)

Many of the advancements that were first made in 802.11n are also included in the Media Access Control (MAC) layer. One noteworthy improvement is the increased aggregate MAC Protocol Data Units (MPDUs) maximum size (1 MB), which leads to greater throughputs due to decreased overhead.

Additionally, 802.11ac will consume less power, have a longer range, and offer faster speeds than earlier generations. It is anticipated that integrated 802.11n/ac radios will be quickly adopted and receive extremely strong industry backing.

In terms of regulatory changes, the FCC’s most recent notice of proposed rulemaking (NPRM) adds 195 MHz to the 5 GHz spectrum for WiFi use. More wideband channels (80/160 MHz) and larger capacity will be possible as a result.

Heterogeneous Networks (HetNet)

A term used to describe contemporary mobile communication networks is heterogeneous networks (HetNet). Different cell types and access technologies are combined to create a contemporary mobile communications network.

HetNet’ Explosive Consumer Demand

Cellular networks have been under extreme strain as a result of the recent explosion in mobile data consumption, and this trend is anticipated to continue as the demand for mobile data nearly doubles every year.

According to Qualcomm’s “The 1000x Mobile Data Challenge,” this indicates a 1000 fold growth in mobile data consumption within 10 years. Additional network resources, such as more spectrum, higher system spectral efficiency (bps/Hz), and spatial spectrum reuse, are required to meet the growing demand for mobile data.

The result is that in order to meet the anticipated demand for mobile data, future mobile and wireless networks’ capacity density (Mbps/m2) will need to be greatly raised. The key reason why current 3G/4G cellular networks won’t be able to meet this demand is a scarcity of (licensed) spectrum.

Reusing Limited Wireless Spectrum

Consequently, one of the most promising strategies to ease the capacity bottleneck is to reuse the limited wireless spectrum over tiny areas utilizing small-cell technology. Small-cells will utilize both licensed and unlicensed airwaves and integrate LTE and WiFi technologies.

Most smartphones, tablets, and laptops now come with WiFi, thus for many users it has replaced other connections (when accessible). In the next three years, WiFi access points and network management software are estimated to deliver half of all IP traffic, making them crucial to carriers. The capacity squeeze may be eased with the addition of more than 600 MHz of unlicensed airwaves in the 2.4 and 5 GHz bands. Because of this, WiFi has gained support from several operators as a different radio access technique.

Additionally, this technology will ultimately be incorporated into the operator network as a component of the service offering. However, a number of changes must take place in order to get over some of the drawbacks of present WiFi networking, particularly those related to security and user experience.

The new 802.11ac standard for very high speed networking, Hotspot 2.0 Next Generation Hotspot for a cellular-like experience, WiFi offload, and WiFi-3GPP network integration are a few recent advancements in WiFi networking that are crucial for small-cells and HetNets.

5G mmWave aids in achieving a sizable return on investment

A ground-breaking advancement in cellular technology, 5G mmWave gives users access to the enormous bandwidth and capacity seen in frequency bands over 24 GHz. The wireless ecosystem has now adopted 5G mmWave, which was formerly dismissed by doubters as being unachievable but is now gaining popularity worldwide.

Everyday, the enhanced user experiences and consumer happiness result in substantial monetization potential and new prospects for carriers. Learn from these studies about the financial advantages and affordability of implementing 5G mmWave, which include many nations and deployment scenarios such as dense urban, indoor businesses, and fixed wireless access (FWA).

Wireless Communication Engineering

An expert in wireless technology development, research, and application is a wireless communications engineer. Electronics, wireless phones, radio frequency technology, broadband networks and systems, routers, and modems are some of the areas where wireless communication engineering tasks tend to be specialized.

As a member of a project team for wireless integration consulting, our engineers spend a great deal of time conducting research and development and introducing fresh ideas for gadget designs.

Engineers also concentrate on increasing the effectiveness of current ones. Team duties for wireless integration consulting include creating customized systems that generate the best possible signal strength, speed, security, and network capability as well as debugging existing networks to ensure that they operate at maximum efficiency.

The “Big 4” of Wireless Networks

The size, range, and connectivity requirements of the four types of wireless networks—wireless LAN, wireless MAN, wireless PAN, and wireless WAN—vary.

Wireless local area networks, wireless metropolitan area networks, wireless personal area networks, and wireless wide area networks are the four different types of wireless networks, each with a distinct purpose.

We will go over the various wireless network kinds, as well as the numerous tools and connections each one needs, in the accordion dropdowns below.

WLAN Technology

Within a building or in a small outdoor area, internet connection is made possible through wireless LAN (WLAN) technology. WLAN technology was initially utilized in homes and businesses, but is now present in shops and dining establishments.

Due to the COVID-19 pandemic forcing office workers, students, teachers, and others to work and study from home, the use of home networks has significantly expanded.

Most home network layouts are straightforward. A modem connects to a local service provider’s cable or fiber. The signal is received by a wireless router that is connected to the modem and broadcasts it using a wireless protocol, such as the 802.11 standards.

The networks in offices are more intricate.  The networks in offices are more intricate. Each of the ceiling-mounted access points (APs) broadcasts a wireless signal to the surrounding environment. Large offices need multiple APs, each of which connects to the office backbone network through a wired link to a switch.

WMAN Technology

In order to give people access outside of an office or home network, wireless metropolitan area networks have been set up in cities all over the world.

Although these networks have a larger coverage area than networks in offices or homes, the fundamentals are the same. All around the service region, APs can be seen on the exterior of buildings or atop telephone poles.

APs transmit a wireless signal throughout the region while being wired to the internet.

Users connect to the closest AP, which then forwards the connection through its internet connection, to reach their intended destination.

WPAN Technology

Using protocols like Bluetooth and Zigbee, wireless personal area networks often only cover a very small area—a maximum of 100 meters (~325 feet) for the majority of applications.

Hands-free phone calls, earpiece connections, and signal transmission between smart gadgets are all made possible via Bluetooth.

For instance, an IoT network’s stations are connected through Zigbee. Line of sight applications for infrared technology, such as linking TV remote controls to TVs, are restricted.

Through the development of novel signal transmission techniques, wireless engineers have continuously enhanced technology. Each of these wireless technologies can now provide faster data rates and longer range thanks to these developments.

WWAN Technology

In order to enable access outside the coverage area of a wireless LAN or metropolitan network, wireless WANs use cellular technology.

These networks allow users to call other people who are connected via a wired or wireless wide area network. Additionally, users can access websites and server-based apps by connecting to the internet.

In the United States, Canada, and the majority of other nations, cell towers can be found almost anywhere.

Whenever a user connects, the connection is forwarded to the closest cell tower, which is then either connected to the wired internet or to another tower that is.
