The Emerging Wireless Infrastructure

The Evolution of Networking: Integrating Cellular, Bluetooth, and Wi-Fi Connectivity

 
PRLog - Aug. 24, 2011 - STATE COLLEGE, Pa. -- Cell phones were originally designed for voice communications over the public cellular networks. Over time, Bluetooth wireless connectivity was added for convenience and connectivity to accessories. More recently, Wi-Fi has been integrated into most smartphones. The challenges inherent in integrating these technologies provide keys to planning and implementing new network designs.

Wi-Fi was originally envisioned by the IEEE 802.11 wireless LAN architects as a convenient wireless replacement for cables in an Ethernet network wherein the Wi-Fi semiconductors could be powered by the PC's power supply or a laptop computers large battery. Power efficiency was not a primary factor in the original Wi-Fi architecture. So when Wi-FI chips designed for laptops are integrated into cell phones or smart phones, they tend to draw an undesirable amount of power from the small cell phone battery.

According to a report from UBM TechInsights, Bluetooth had achieved 100% adoption into handsets by 2010, and by 2010 Wi-Fi had achieved a 92% adoption rate. Wi-Fi growth was largely fostered by the use of single chip solutions integrating Wi-FI and Bluetooth with a 62% adoption rate by 2010. Although the availability of Wi-Fi in standard handsets is still limited, the fastest growing segment of phones, the smartphones, all have Wi-Fi integration. Enabling Wi-Fi on a smartphone has an impact on battery life well beyond that of cellular-only usage.

Recognizing an impending deficit in available cellular spectrum, cell phone companies encourage more mobile traffic to be unloaded onto available Wi-Fi networks.  The FCC projects data usage to cross a critical threshold at the end of 2012 (http://transition.fcc.gov/Daily_Releases/Daily_Business/2...) due to increased web, data, and video traffic. In order for their networks to continue to provide spectrum for essential voice communications, the cellular companies will more freely permit the mobile Web, data, and video traffic to be unloaded onto public or private Wi-Fi networks in homes, offices, and public spaces. From the standpoint of spectrum conservation, throughput, and availability, it behooves everyone to off-load a portion of this ever-increasing traffic to available Wi-Fi networks.

The aforementioned trends to increase Wi-Fi usage, and limitations of Wi-Fi in smartphones, have not gone un-noticed by the chipset manufacturers. In fact, the recent acquisition of wireless LAN chipset manufacturer Atheros by Qualcomm, the leading cellular chipset manufacturer, is positive affirmation of the need for the wireless LAN and cellular technologies to coexist and compliment one another. As stated by Dr. Paul E. Jacobs, chairman and CEO of Qualcomm, "It is Qualcomm's strategy to continually integrate additional technologies into mobile devices to make them the primary way that people communicate, compute and access content. This acquisition is a natural extension of that strategy into other types of devices." Said Steve Mollenkopf, EVP and group president of Qualcomm, "We see this strategy as central to helping our customers capitalize on the ubiquitous connectivity and seamless experiences that are developing across mobile phones, computing and consumer electronics."

From these statements, it appears probable that the Atheros Wi-Fi chipset technology is going to be more thoroughly integrated into the handset, especially with regard to conservation of battery power and improved mobile performance. In the near future, smartphones and tablet computers will likely have "always-on" Wi-Fi capability, without as noticeable an impact on battery life. Additionally, Atheros has been a leader in integrated 2.4 GHz and 5 GHz Multiple Input Multiple Output (MIMO) Wi-Fi chipsets, exploiting the 500 MHz of bandwidth available at 5 GHz versus the 80 MHz of bandwidth available at 2.4 GHz. So, although smartphones possess 2.4 GHz Wi-Fi at this time, very soon they will possess both 2.4 GHz and 5 GHz Wi-Fi.

Wireless networking is not a matter of cellular or Wi-Fi, it is both technologies acting in concert. And, from the standpoint of building the wireless infrastructure, the designer needs to be cognizant of the fact that handsets, mobile computers, and other devices will imminently anticipate the availability of a robust, mission-critical cellular network and dual band Wi-Fi wireless LAN.
