Wireless

Why should you go wireless?

If you operate from a number of different locations, or need to find a temporary connectivity or redundancy solution, a wireless link can prove to be a more cost-effective solution than a leased line.

Wireless links can be used not only to connect all types of telecommunication systems, but also to interconnect your corporate network, including voice telephony.

When can a wireless link be used?

Distance
Wireless links can operate easily at distances up to around 40 kilometres, as long as there is a direct line of sight between antennas linking the connection points. Links over greater distances require antennas mounted on tall masts or high buildings because of the Earth's curvature.

Capacity and reliability
Wireless links with bandwidths up to and over 155 Mbps are perfectly feasible. Equipment redundancy combined with a service contract can guarantee continuous operation, avoiding any risk to your critical business processes.

However, a few extreme meteorological conditions can cause power outs usually lasting no more than a few seconds. Typical user interfaces employed for wireless links include V.35 for nx 64kbps, nx E1, E3 and 3x E3, STM-1, nx STM-1, 10/100BaseT and Gigabit Ethernet.  

Applications suitable for use over wireless links

  • Wireless links can offer solutions where a network connection is needed over distances of up to around 40 kilometres. They are particularly effective when used for large bandwidth networks.
  • Multiple office sites/locations:
    ideal for linking 2 or more sites up to around 40 kilometres apart.
  • Glassless sites:
    A wireless link can be more cost-effective and faster to set up in sites not yet equipped with fibre optic cabling.
  • Redundant links:
    Business-critical systems require redundant connectivity. Should a cable fault develop or a breakage occurs, e.g. due to excavation works, a wireless link can provide an alternative pathway.

Tein Telecom has extensive experience in setting up systems to cope with scenarios like these, consistently seeking the most appropriate, most efficient solution for your organisation's specific communication needs.

LAN / MAN Networks

in

Finding the most suitable, high-performance network solution for your ICT environment can depend on several key factors.

While Ethernet has been the preferred communication medium for IT networks, the technology is now shifting towards MAN/WAN networks, which will challenge media like SDH and ATM.

Implementing QOS on Ethernet backbones enables them to support different applications in direct competition with ATM based Backbones. Distances and bandwidths delivered by SDH are countered with the Gigabit and 10 Gigabit technologies, which range up to 70 km.

The Multi-service Ethernet Backbone delivers connectivity and transport over medium-large distances (MAN) of Voice, Video and Data, making it the only medium for all next-generation IP-based communication needs.

Tein Telecom's in-depth expertise will help you to enable such a multi-service backbone, from initial design to implementation and support.

Interfacing the network

Does your organisation have an optical backbone or does it lease a large dark fibre capacity from an operator? If so, you know that it cannot provide the appropriate interface for all users and applications across the network. Many types of interface do not simplify matters - in fact the contrary is true.

Access systems associated with Wide Area Networks (WAN) used with large SDH or ATM networks can help by providing an excellent additional solution to give users the network connection they need. Whatever your network needs, Tein Telecom has the experience and expertise to find you a solution.

Technologies in which Tein Telecom has been closely involved over the years include:

Time Division Multiplexing
TDM-based systems reserve part of the bandwidth for each user and ensure it is offered it with the correct physical interface. This enables you to provide static links between it and other users or systems.
Applications include nx64k leased lines for data links or telephone and ISDN connections.

Digital Subscriber Line Access Multiplexer (DSLAM)
Operators use DSLAMs to bundle various xDSL connections (e.g. ADSL and VDSL) to a high-speed ATM link. Thus DSLAMs may be considered to be concentration points over transport networks.

Access Synchronous Digital Hierarchy (SDH) solutions
While mainly used for large backbone networks, SDH technology is increasingly expanding into the access side of the network. Small STM-1 (155Mbps) multiplexers provide you with transport potential for applications such as E1 or Ethernet links. This brings you the benefit of a significant advantage of SDH: a redundant network with extremely fast switchover times in the event of incidents such as a fibre fault.

Analogue Interfaces on the IP Backbone
The current trend towards ever-greater use of TCP/IP as the transport technology also has an impact on the access equipment. TDM over IP equipment enables you to transport traditional access interfaces such as RS232, E&M, analogue voice (with or without compression), etc. without needing to invest in expensive new routers.
TDM over IP also causes very little signal delay, making it an ideal solution for time-critical applications such as telephony.

Network Transport

Transporting data

Telecom operators have to invest in cost-effective, flexible and reliable mass transport systems to keep up with the increasingly aggressive pace of competition. This will enable you to reduce the cost per circuit in the core network while ensuring a robust SLA.

Current network modes from most telecom operators are made up of 4 layers:

  • IP or other content-delivery access layer,
  • ATM or MPLS network to drive the data traffic,
  • SDH transport network with very high availability
  • DWDM layer providing a massive expansion in your fibre capacity.

Over recent years, Tein Telecom has implemented and maintained many operators' transport networks, and similar numbers of less complex systems for the utilities sector. Due to its high reliability and bandwidth, SDH is exclusively used in most of these transport networks.

3G Networks

The arrival of 3G wireless networks and the anticipated growth in network capacity will make it essential for operators like you to invest in an appropriate core network. This will enable you to offer a wide range of services to convince potential customers.

To ensure that your current network is as future-proof as possible and enable you to continue upgrading it using the latest technologies, it needs to be based on a technology-independent architecture. IP is increasingly used as the transport environment, sometimes combined with DWDM. IPv6 and MPLS switches provide the required bandwidth, functionality and Quality of Service that previously only ATM and SDH networks were capable of supplying.
