In which modes HiperLAN2 network can operate?
In which modes HiperLAN2 network can operate?
HiperLAN/2 system operates at the 5GHz region. The frequency allocation in Europe is: 5.15-5.35 GHz, lower band (indoor use only) and 5.47-5.725 GHz, upper band (indoor and outdoor use). HiperLAN/2 can be used as an alternative access technology to a 2nd and 3rd generation cellular network.
What is HIPERLAN in wireless network?
HiperLAN (High Performance Radio LAN) is a wireless LAN standard. It is a European alternative for the IEEE 802.11 standards (the IEEE is an international organization). It is defined by the European Telecommunications Standards Institute (ETSI).
What are the two modes of operation of HIPERLAN 2?
HiperLAN2 relies on cellular networking topology combined with an ad-hoc networking capability. It supports two basic modes of operation: centralised mode and direct mode.
Why is HIPERLAN used?
HIPERLAN uses cellular-based data networks to connect to an ATM backbone. The main idea behind HIPERLAN is to provide an infrastructure or ad-hoc wireless with low mobility and a small radius. HIPERLAN supports isochronous traffic with low latency.
What is the difference between WiFi and WiMax?
WiMax handle a larger inter-operable network. WiMax can be used to provide internet services such as mobile data and WiFi spots….Difference between WiFi and WiMax:
| WiFi | WiMax |
|---|---|
| WiFi is short range technology. | WiMax is long range technology. |
| WiFi connection can transmit upto 54 mbps. | WiMax connection can transmit upto 70 mbps. |
How is Bluetooth useful in mobile computing?
You can use it for transferring the data, and verbal communication as Bluetooth can support data channels of up to 3 similar voice channels. It doesn’t require line of sight and one to one communication as used in other modes of wireless communications such as infrared.
What is HIPERLAN explain its features?
A high-performance local area network (HIPERLAN) is an alternative wireless LAN standard to the IEEE 802.11. HIPERLAN uses cellular-based data networks to connect to an ATM backbone. The main idea behind HIPERLAN is to provide an infrastructure or ad-hoc wireless system with a small radius.
What is Zigbee in mobile computing?
Zigbee is a wireless technology developed as an open global standard to address the unique needs of low-cost, low-power wireless IoT networks. The Zigbee standard operates on the IEEE 802.15. The protocol allows devices to communicate in a variety of network topologies and can have battery life lasting several years.
How does the Bluetooth layer provide confidentiality and Authorisation?
Bluetooth security supports authentication and encryption. These features are based on a secret link key that is shared by pair of devices. A pairing procedure is used when two devices communicate for the first time to generate this key.
