radio waves in wireless network
Usually, you can't see all those analog bits (and the cleverness of the board layout) because all the modem is encapsulated in a metal shield to protect your PC from those high frequency radiations.. The amount of on-board memory is also important, because the MAC may need a significant number of buffers to compensate the PC and interface latencies.. Wireless Overview - Anatomy of a radio LAN 3 Anatomy of a radio LAN A radio network is a collection of nodes communicating together through radio devices, using radio waves to carry the information exchanged (obvious, isn't it?

what radio waves does wifi use
) It is sometime called a radio Ethernet, by analogy of the wired technology Most radio devices are a card (ISA, Pcmcia) to plug in a PC (or workstation), and interact directly with the standard networking stack on it (no need of PPP or any specific protocol stack).. The card also includes some memory for the MAC controller to store incoming and outgoing packets (buffers) and other data (configuration, statistics).. A radio device is composed of two main parts The first is the radio modem This is the part transmitting (modulating) the data onto the frequency and receiving other transmissions..

are wifi radio waves dangerous
The main characteristics of the MAC are the packet format (size, headers), the channel access mechanisms and the network management features.. While this opens up new possibilities for mobile connectivity, it must be remembered that the wireless network is an institutional resource made available for the benefit of the Caltech community.. Most of the time the few most time critical parts are handled in the radio modem ASIC (the baseband), the bulk of the MAC in a microcontroller and only some management functionality in the driver. ae05505a44 HERE
what is the difference between wifi and radio waves
The MAC address or hardware address or physical address is a unique code that is assigned to each piece of network.. These are mainly analog parts, and a bit of digital (in an ASIC, the Baseband) Wireless networking is a technology that allows computers and other electronic devices to have network connectivity using radio waves instead of wires.. It is composed of antenna(s), amplificators, frequency synthesisers, filters and other bits of magic.. People building modems are also talking a lot of SNR and dB The second part of the radio device is the MAC controller, responsible to run the MAC protocol.. The modem main characteristics are the frequency band, the signalling rate, the modulation and the transmitted power. 5
