    • What is Multicast Wireless?

      What is Multicast Wireless?

      Multicast is the transfer of messages to multiple destinations simultaneously, using fewer networks. The information is delivered to each of the links only once, and copies are created when the links to the destinations split, thus creating an optimal distribution path. Multicasting reduces unnecessary packet duplication. A wireless network utilizes radio communication, unlike wired networks,

    • What is ZigBee?

      What is ZigBee?

      ZigBee is a wireless protocol that was developed as an International standard to enable wireless, machine to machine communication, and networks. It is considered the catalyst for constructing “Smart” enabled buildings and homes since it is based on reliable network communications, a pro-longed battery life, and can be simply operated. The ZigBee Alliance is the

      SSID (Service Set IDentifier)

      The SSID (Service Set IDentifier) is a name that identifies a specific 802.11 wireless network. The name is set by the network administrator who configures the router. Some vendors refer to the SSID simply as the “network name.” The SSID is the name of the wireless network and should not be confused with the host

      Access Point

      As technology has advanced, devices have become more complex and integrated. Access points make a good example of such devices. These can be described as hardware that includes a modem, router, and other optional functions that are all compiled into one device. Access points are becoming more popular than modems or routers and they are

    • MMDS (Multichannel Multipoint Distribution Service)

      MMDS (Multichannel Multipoint Distribution Service)

      MMDS (Multichannel Multipoint Distribution Service) is a broadband wireless point-to-multipoint specification utilizing UHF (Ultra High Frequency) communications. MMDS operates on FCC licensed frequencies. The FCC divided the United States into BTA's (Basic Trading Areas) and auctioned the rights to transmit on the MMDS bands in each of those areas to MMDS service providers. The MMDS

    • What is a Smart Antenna?

      What is a Smart Antenna?

      A smart antenna is one that transmits or receives multiple radio frequencies at once. Smart antennas increase data transfer rates and reduce errors by handling several copies of the same information. Conventional antenna systems consist of one antenna that serves as a transmitter and one that serves as a receiver. This is starting to change,

    • What is Intersymbol Interference?

      What is Intersymbol Interference?

      Intersymbol interference is a signal distortion in telecommunication. One or more symbols can interfere with other symbols causing noise or a less reliable signal. The main causes of intersymbol interference are multipath propagation or non-linear frequency in channels. This has the effect of a blur or mixture of symbols, which can reduce signal clarity. If
