5.3. Speed-to-Market Advantages

It is predicted that the overall adoption rate for UWB will be more than triple that for Wi-Fi due to the following reasons.

Leveraging Existing Standards

While 802.11 was created from the ground up (MAC, PHY, etc.), the 802.15.3a is based on an existing MAC from 802.15.3 and is targeted at products that already have completed upper layers (USB 2.0 and 1394).

Multi-Industry Momentum

The current industry organizations such as the MBOA and IEEE 15.3a groups include most of the leading PC, CE, and semiconductor companies who have mostly collaborated so far toward achieving a common standard.

Increasing Consumer Demand for Plug-and-Play Digital Content Storage

Both the PC and CE industries are focused on providing plug-and-play solutions for storing as well as sharing their video and audio contents between consumer electronics devices and PCs. The number of consumer devices with integrated hard drives is doubling and the demand for related products is increasing by more than 50 percent per year [1].

UWB Is Targeting a Broad Range of Products

These include PCs, notebooks , DVD players, printers, camcorders, digital cameras , game consoles, digital TVs, and stereos. Many of these have been increasing by at least 50 percent per year.

Single Standard

Unlike cables, the wireless PAN market requires that all UWB systems cooperate to prevent interference with one another.

Flexible and Scalable

UWB provides variable spectral filling of the wideband channel and better coexistence with other radio systems. It also enables scalable performance in terms of technology advancement and application requirements.

Low Cost

UWB enables full CMOS integration that will eventually lower the production costs and provides easier integration. The switching cost for manufacturers to use UWB instead of or as well as FireWire and/or USB 2.0 is also very low.

Low Power

Power consumption to data rate ratio (mW/Mb) will be 5 to 10 times better than 802.11 and includes scaling to the power requirements of small battery- powered CE devices such as digital audio players and handheld computers.

Recent developments in both the consumer electronics and PC industries make UWB an almost perfect wireless solution to drive and benefit from the ongoing convergence of entertainment and computing. A few of these products include audio and video projection, still and video camera links, game consoles/controls, home theater systems, set-top boxes, and portable audio devices. In the next five to ten years , UWB will also likely be used in mobile communications devices such as smart phones, in order to integrate the mobile industry with the CE and PC industries as well.

UWB's existing target markets (excluding WLAN and low-data WPAN) will include more than 1 billion units shipped in 2008. As Figure 5-2 illustrates, ON World's UWB projections are based on a relatively small percentage of the greater target market for the next few years, with almost unlimited potential beyond this.

5.4. Driving CE, PC, and Mobile Industry Convergence

Consumers typically have three or more display devices in their home that will need to receive at a minimum the MPEG-2 video format. With digital TV, flat panel displays (plasma and LCD), DVD, DVR, and digital camera sales at an all-time high, it is clear that consumers' move to a multimedia home environment and wireless connectivity within those devices is a natural next step. Today, consumers must deal with multiple wired interfaces such as 1394 (FireWire) or USB (1.1 or 2.0), which complicates the interoperability among the PC-oriented products and consumer electronics devices. Although USB 2.0 is being incorporated in a greater number of consumer electronics devices, there is still a significant " barrier of interfaces" that prevents true interoperability between the PC and CE industries. Figure 5-3 illustrates this division.

Ultra-wideband will enable consumers to take that next step to pervasive connectivity within the home. Over the next five to seven years this interoperability will transfer to mobile communications devices such as smart phones as well. The need for interoperability is just one reason why UWB adoption will increase at a much faster rate than either USB 2.0 or FireWire. In fact, there are several current industry trends, such as existing market conditions, that will drive UWB adoption:

  • Increasing multimedia usage in the home.

  • Increasing usage of entertainment storage devices: sales of consumer gear with hard drives are growing by 50 percent per year [2].

  • Ongoing convergence between PC and CE industries.

  • Rapid growth of Wi-Fi in homes .

  • Rapid growth of several consumer-oriented digital devices.

  • Emergence of integrated devices, such as DVD players/recorders and personal video recorders (PVRs), with added functionality.
