Area, Wide Area & Wireless Networks
Wide and local area networks are rapidly growing in complexity as new developments bring greater
business benefit to corporate organisations that require a reliable network infrastructure. Growing
complexity places greater demand on increasingly specialised network design expertise.
It is clear that services such as remote access, voice
and video conferencing contribute to business
efficiency. These services can impact network
performance if bandwidth and capacity constraints
are not adequately assessed.
The right expertise is the key to success in designing, planning and implementing a network solution.
Wireless LANs have increased in popularity due to their flexibility, however they do present new
security challenges, these can be addressed with the more recent wireless standards such as WPA
and 802.11i. We support and implement the following:-
• Fast Ethernet
• Switched Ethernet
• Token Ring
Wide Area Network Technologies:-
• Frame Relay
• Leased Line
• Dialled Circuits
In gathering requirements to enable the best solution for the project, the right decisions must be made, this
will ensure criteria are met for scalability, throughput, response times, best use of bandwidth and an optimal
universal addressing scheme. Some designs will require resilience eliminating all single points of failure,
these requirements are best understood at an early stage.
To make the most of developments that are relevant for your needs there must be an awareness of how the
different vendors are incorporating new technologies into their products. We work with the technologies and
products from all the major networking vendors. Where there is advantage to be gained this must not be
outweighed by the overheads of installing new technology.
Congestion is one factor that can affect network performance especially on WAN links where queuing
delays can eventually result in lost packets. Backup schemes using SANs must be carefully planned to
avoid putting additional pressure on existing WAN links. Packet loss results in re-transmissions which can
increase pressure on limited bandwidth resource. The likelihood of these problems must be assessed and
