What is a wireless sensor?
A Wireless sensor network, according to UbiBot, is a collection of devices that can exchange data gathered from a monitored field using wireless networks. The data is routed across numerous nodes and connects to other networks via a gateway, such as wireless Ethernet.
What collect data from many points over an extended space?
wireless sensor networks
Why routing is required in wireless sensor networks?
Since, wireless sensor networks (WSNs) might differ depending on the application and network architecture. Moreover, nodes are dynamically deployed. Hence, data transmission through these types of nodes need a perfect route selection where nodes should remain active. So, routing is necessary for WSN.
Are wireless networks laid out using the same topologies as wired networks?
Wireless networks are not laid out using the same topologies as wired networks. They have their own, different layouts. Smaller wireless networks, in which a small number of nodes closely positioned need to exchange data, can be arranged in an ad hoc fashion.
Actual data throughput is usually higher on wireless networks?
Data is usually higher in wired network then wireless. This is because to is plugged directly in.
What signals do wireless networks use to send data?
Radio frequency signals.
How do you turn off 3g on lg optimus slider for virgin mobile?
Go to Settings>Wireless & Networks>Mobile Networks and uncheck the "Data Enabled" box.
How do telephone companies use networks?
they used to exchange data in a wireless system. also, so that data will be group and connect each other in one communication
Is a hardware device with one or more antennae that permit communication between wired and wireless networks so wireless clients can send and receive data?
Network Interface card
Which type of modems is better wireless or cable?
Those are 2 different things. There are cable modems and DSL modems. Wireless refers to a type of network which can be based either on a Cable modem or a DSL modem. You can have a wired network, or a wireless network. Wireless networks have typically have had slower transfer rates than wired networks, but the technology is changing so wireless routers are becoming faster in transferring data.
How do wireless electronics work?
Wireless electronics work using small components and batteries. If the wireless Xbox accessories are what are being asked about they work with a infrared sensor to send coded data to the system.
What is Wireless mesh?
Wireless Mesh is terminology used to describe a wireless data network. What makes Mesh Networks so appealing is their ability to be deployed in all types of environments. Mesh Networks are commonly found supporting voice, data, and video. Municipal links commonly support video surveillence application throughout a community. The advantage of a Wireless Mesh Network is that it uses wireless switching that routes data via the path of greatest efficiency ala Ohm. A disadvantage of wireline networks is that they are vulnerable to a single point of failure. Wireless Mesh Networks are comprised of nodes that may support access points or simply data transmission. Vehicles may also act as nodes when equipped with an embedded node. Vehicles may also be used to extend a network. If a tornado takes out a node, you simply dispatch a node equipped vehicle to take its place. Also, when a node goes down, data is switched around it, keeping the network up.
