HiperLAN2 – The
Broadband Radio Transmission Technology Operating in the 5 GHz Frequency
Band Up until now, wireless networking has been more or less
synonymous with wide area cellular networks based on different standards,
e.g. GSM, AMPS, etc. They have been defined with the main purpose of
supporting voice, though some also offer datacom services at very low
speed (~10 kbits/s). Wireless datacom service offering the throughput
necessary to meet the actual requirements for Internet and Internet access
is just on its way to hit the market on a broader scale. In the LAN
environment, Wireless LAN (WLAN) products based on the different flavors
of 802.11 are available from a range of vendors. Depending on transmission
scheme, products may offer bandwidths ranging from about 1 Mbit/s up to 11
Mbit/s...

The HIPERLAN/2 specifications are developed by ETSI
BRAN, responsible for Broadband Radio Access Networks standardization
within ETSI. HIPERLAN/ 2 is a flexible Radio LAN standard designed to
provide high speed access (up to 54 Mbit/s at PHY layer) to a variety of
networks including 3G mobile core networks, ATM networks and IP based
networks, and also for private use as a wireless LAN system. Basic
applications include data, voice and video, with specific QoS parameters
taken into account. HIPERLAN/2 systems can be deployed in offices,
classrooms, homes, factories, hot spot areas like exhibition halls and
more generally where radio transmission is an efficient alternative or a
complement to wired technology. |

HIPERLAN/2
(Janne Korhonen) The need for mobile broadband communications has
increased rapidly in recent years placing new demands for the wireless
local area networks. These requirements include support for QoS, security,
handover, and increased throughput. To answer these needs, ETSI is working
on HIPERLAN (HIgh PERformance LAN) standards of various types. These
standards merely describe the low-level interfaces and leave the higher
level functions open. This essay will concentrate on HIPERLAN/2, a
state-of-the-art WLAN technology that has been developed to provide a
wireless access to fixed networks. This is intended to be a short overview
of its main features and protocol reference model. |

A Universal
MAC/PHY Interface for Different WLAN Standards WLAN is widely
considered to play a major role in wireless multimedia communications. Two
competing standards: IEEE802.11a and HIPERLAN/2 will dominate WLAN market.
These two standards have a similar physical layer that is based on OFDM
technology, but the Medium Access (MAC) layers are different. MELCO is
currently developing the chipset for WLAN. MELCO has strong capabilities
in the radio front end as well as OFDM implementations. The project here
is to develop a universal interface between MAC and Physical (PHY) layers.
This allows the reuse more of PHY components in both IEEE802.11a and
HIPERLAN/2 products, and helps MELCO's position in WLAN chip market. In
this way several WLAN manufactures could use the MELCO PHY chipset and
connect any of the WLAN MAC layers to this PHY chipset. |

Planning
and Implementing Wireless LANS-5 While we emphasize how to take
advantage of wireless LANs today, it is worth noting some of the ongoing
developments and what to expect over the next five years. This will give
you a better idea of how wireless LANs might address your expanding needs,
and whether you will be able to consider wireless LANs for other
applications. There are a number of notable trends. Expect to soon start
seeing HiperLAN products offering about 24 Mbps. And standards work is
already under way with HiperLAN and a wireless version of ATM to extend
speeds to 155 Mbps, though affordable products at such higher data rates
probably will not be available for another five years.
