A Mobile Handheld Device Structure

---

Comments about two of the three features of handheld devices, limited network bandwidth and small screen/body size, are given below:

• The limited network bandwidth prevents the display of most multimedia on a microbrowser. Though the Wi-Fi and 3G networks go some way toward addressing this problem, the wireless bandwidth is always far below the bandwidth of wired networks.


• The small screen/body size restricts most handheld devices to using a stylus for input.

The above figure shows a generalized system structure of handheld devices, which includes the following six major components:

1. a mobile operating system,
2. a mobile central processing unit,
3. a microbrowser,
4. input/output devices,
5. memory, and
6. batteries.
