SUA Statement
PT. Sarana Usaha Abadi is a trusted expert in wireless mesh networks for broadband applications. We have delivered wireless mesh solutions for over two years into mission critical environments for wireless broadband, public area, and hard-to-wire terrain. Our family of wireless mesh network equipment and network management software is purposely designed for voice, video, and data.

Price:
802.11 radios have become quite cheap, but the radios are often still among the most expensive elements of such a network. The fact that each mesh node runs both as a client and as a repeater potentially means saving on the number of radios needed and thus the total budget.

Ease and simplicity:
If you have a box that is pre-installed with wireless mesh software and uses standard wireless protocols such as 802.11b/g, the setup is extremely simple. Since routes are configured dynamically, it is often enough to simply drop the box into the network, and attach whatever antennas are required for it to reach one or more existing neighboring nodes (assuming that we can solve the issue of IP address allocation).

Organization and business models:
The decentralized nature of mesh networks lends itself well to a decentralized ownership model wherein each participant in the network owns and maintains their own hardware, which can greatly simplify the financial and community aspects of the system.

Network robustness:
The character of mesh topology and ad-hoc routing promises greater stability in the face of changing conditions or failure at single nodes, which will quite likely be under rough and experimental conditions.

Power:
The substrate nodes of a mesh network -- possibly excepting those nodes that maintain an up-link to the Internet -- can be built with extremely low power requirements, meaning that they can be deployed as completely autonomous units with solar, wind, or hydro power. (A side comment: Piggybacking mesh networks on projects that primarily aim at energy production might be a very feasible strategy -- with every panel or windmill, a node. Power generating units are typically connected to points of infrastructure and human presence. This makes them valid locations for network nodes. As a secondary benefit, the presence of integrated network nodes within power networks may allow for better monitoring and management.)

Integration:
Mesh hardware is typically small, noiseless, and easily encapsulated in weatherproof boxes. This means it also integrates nicely outdoors as well as in human housing.

Reality fit:
Reality rarely comes as a star, ring, or a straight line. In difficult terrain -- be that urban or remote -- where not every user can see one or few central points, chances are she can see one or more neighboring users.
