The most common business use of wireless microwave links, are to use as a replacement for a Leased Line or a 'point-to-point' link. Organisations with two or more sites need reliable, high-speed connections between their sites to enable them to share voice & data services between the sites. This is a Wide Area Network (WAN) requirement and Microwave links provide a cost effective WAN alternative solution to Leased Lines. The same set-up can also be used to link a business to a Internexus linked site to gain Dedicated Internet Access.
A Microwave link can connect two sites that are within range and have a line of sight. If the two locations are within several kilometres of each other and the path is not too obstructed with hills or tall trees, then a high performance microwave wireless link can usually be connected between them. Using suitable frequencies, it may be possible to link sites with no clear 'line of site' at lower bandwidths.
Microwave links are used by all types of users from small enterprises, colleges, health authorities, government and large private companies
The microwave link itself consists of hardware at each site consisting of suitable Microwave Dish, Transmitter/Receiver Unit and Router.
Fast: Speeds of 10Mbps to 1GBps can be achieved.
Carrier Grade: 99.999% reliable, with full Quality of Service support
Cost effective: Lower recurring costs makes the total cost of ownership competitive
Secure: Operates on secure high frequencies unable to be detected by unauthorised users
Flexible: Speeds can be increased in the future.
A Leased Line provides 10Mb, 100Mb or 1Gbps connectivity, but has high recurring costs. Users that are not connected with existing optical fibre, may also be charged very expensive set up charges to lay new fibre connections to their site.
A VPN (Virtual Private Network) can provide connections between sites using the Internet connection at each site, typically ADSL connections. ADSL appears to be very cheap, offering speeds of 8 or even 20Mbps for very low prices, but suffers from very low upstream bandwidth (6% of downstream), contended with up to 20 or 50 other users, and has no Quality of Service. Thus such VPN IP links would in practice be slow and may not be suitable.
The most common use is replacing Leased lines and providing point to point links for voice, data and Dedicated Internet Access as above. Other uses include:-
Internexus has extensive experience in all the elements necessary to make a wireless network operate efficiently. Wireless network equipment will only provide a high performing, reliable system if it has been planned, designed and installed correctly. Internexus is familiar with the many aspects of a wireless system to ensure network success and can provide its clients with a full range of services that would include:-
Wireless Microwave Links form a key part of Internexus Local Ring projects. Such projects mean that businesses can have low cost high speed links in certain towns and cities that have multiple Internexus points of presence. The business building is directly linked to a Internexus site that is within its line of vision, via the Wireless Microwave Link.
See example Internexus Blackburn Ring Project for more details.
