In semiconductor devices, problems in the device package may cause failures due to contamination, mechanical stress of the device, or open or short circuits. Failures most commonly occur near the beginning and near the ending of the lifetime of the parts, resulting in the bathtub curve graph of failure rates.
An IC package or PCB designer removes signal integrity problems through these techniques: Placing a solid reference plane adjacent to the signal traces to control crosstalk; Controlling the trace width spacing to the reference plane to create consistent trace impedance; Using terminations to control ringing
Occasionally the phrase antenna effect is used in this context, [7] but this is less common since there are many effects, [8] and the phrase does not make clear which is meant. Figure 1(a) shows a side view of a typical net in an integrated circuit. Each net will include at least one driver, which must contain a source or drain diffusion (in ...
In the typical case of a WiFi network, increasing transmission power on the access point only will not solve the problem because typically the hidden nodes are the clients (e.g. laptops, mobile devices), not the access point itself, and the clients will still not be able to hear each other. Increasing transmission power on the access point is ...
Some wireless routers have one or two USB ports. These can be used to connect printer or desktop or mobile external hard disk drive to be used as a shared resource on the network. [2] A USB port may also be used for connecting mobile broadband modem, [3] aside from connecting the wireless router to an Ethernet with xDSL or cable modem. A mobile ...
The modules on the IC are typically semiconductor IP cores schematizing various functions of the computer system, and are designed to be modular in the sense of network science. The network on chip is a router-based packet switching network between SoC modules.
Check your physical phone connection - A loose cable or cord can often be the cause of a connection problem. Unplug all phone devices in your home - Unplug all phone devices in your home, then reconnect just the modem. Try to connect online, and if it works, plug in each device one at a time until you find the one causing the problem.
These devices transmit on 2.45 GHz (between channels 8 and 9) at a strength of 500 mW. Because of channel overlap, this will cause problems for channels 6 and 11, which are commonly used default channels for Wi-Fi connections. Because the signal is transmitted as a continuous tone, it causes particular problems for Wi-Fi traffic.
