The web has become so rich with multimedia content that users everywhere are demanding more and more bandwidth. Regardless of the market — whether it is urban, suburban, or rural — a broadband wireless access solution is by far the most cost effective and quickest way to reach the most customers.

Today's internet service providers need high speed solutions which can be quickly and cost-effectively deployed across wide geographic areas to reach the most possible customers. Fixed wireless access products from Trango Broadband enable service providers to deliver these fast broadband connections for surprisingly low cost of deployment.

A WISP is a Wireless Internet Service Provider. WISPS offer broadband services to business and residential customers utilizing radio-based point-to-multipoint networks. Many WISPs operate hybrid networks consisting of both wired and wireless infrastructure. Through their wireless deployments, traditional ISPs have been able to greatly expand their service offerings, their coverage areas, and their bottom line.

Most WISPs utilize equipment which operates in the license free spectrum (2.4 GHz, 5.3 GHz, and 5.8 GHz) to deliver last mile access. With the right equipment, WISPS can enjoy quick return on investment while offering their customers dependable, high speed, always-on, broadband service.

Many WISPs around the world have enjoyed great success due to the low entry, low deployment, and low maintenance costs of fixed wireless "last mile" solutions. Building a wireless infrastructure means less equipment and less maintenance than traditional cable-based facilities.

Trango's Access5830 solution has been the key wireless infrastructure component for many WISPs throughout the world.

Compared to the leased-line world of wired infrastructure - Wireless ISPs enjoy many advantages:

• Quick and easy deployment.
• You own the infrastructure! No recurring costs to the phone company.
• Low equipment costs! Base station construction cost minimal when compared to long range wired facilities costs.
• The spectrum is free! Using 5.8 GHz and 5.3 GHz unlicensed bands, there are no recurring costs to the FCC!
• Low cost to add subscriber! Once you have deployed a base station, customer acquisition cost is very low.
• It's Fast! While DSL and Cable modem subscribers are limited to slow download speeds — broadband wireless access (BWA) solutions from Trango can provide up to 10 Mbps.
• Flexible Networks — given the ease of deployment, BWA networks are equally easy to change and modify as your business requirements change.

A BWA radio network consists of base stations (or Access Points) and Customer Premise Equipment (CPE) radios aka Subscriber Units (SU). The Access Points (APs) are typically mounted on towers or tall buildings since each customer requires line-of-sight (LOS) back to the base station in order to receive service. Each Access Point delivers bandwidth to each subscriber unit (up to 500) within it's 60 service sector. Because the AP is communicating with multiple SUs, it is considered a point-to-multipoint (PmP) network. Point-to-multipoint networks are very cost efficient and easy to manage since Access points serve as the management portal and their quantities are limited.

One important consideration for WISPs is how to get the bandwidth up to the base station. The preferred method is to deliver the bandwidth through a wireless backhaul or point-to-point link. Using the TrangoLINK-10, service providers can deliver bandwidth up to 40 miles. A PtP link consists of two radios, one on each end. The TrangoLINK-10 is a highly cost-effective wireless Ethernet bridge which provides 10 Mbps connectivity up to 40 miles.

Trango's Access5830 has enjoyed great popularity among hundreds of WISPs around the world. The Acces5830's success can be attributed to the fact that it's design was conceived specifically to allow WISPs the ability to quickly, cost-effectively, and reliably deliver high speed internet access to large numbers of customers in disbursed geographic areas.

The Access5830 offers higher speeds and longer ranges than competing solutions - but equally important is the manageability and scalability of the equipment. Trango solutions exceed in these categories as well.

Performance

The Access5830 delivers lots of bandwidth at great distances. New customers can be added to the network without any noticeable hit on overall speed.

Dependability

The Access5830 utilizes direct sequence spread spectrum (DSSS) Technology. Although we'd like to say we invented DSSS, we did not. DSSS was invented years ago by the US military as a secure, robust, and reliable means to communicate across great distances. The same characteristics of DSSS that worked well for the US military, can work to the advantages of WISPs. DSSS is inherently dependable, efficient, and secure. ISPs can spend more time acquiring more customers and less time maintaining or repairing the network.

Manageability

The Access5830 was designed to provide the ISP with complete control over its wireless network. All Trango radios feature comprehensive management interfaces including Telnet, HTTP, and SNMP built right into the radio. Network operators have full access to the radios to monitor performance, optimize the network, add or modify subscribers. Using SNMP, operators can be alerted to any potential problem on their network.

Scalability

The Access5830 system can grow along with the ISPs business. Adding subscribers is a simple matter of adding the SU to the AP's database. Access Points can be co-located (in fact, up to 22!) to provide coverage to multiple sectors. New base stations can be added and interlinked using PtP radios. The possibilities for growth are endless.

Ease of Installation

One of the most important considerations for cost-containment is ease of installation. In order to minimize truck-rolls and the time that installers spend at each new location, it is imperative that the CPE solution be easily and quickly installed. The Access5830 was designed with this in mind. All of our radios feature Power-over-Ethernet (PoE) and radio/CPE solutions which are integrated together. This means the entire radio is mounted outdoors — on a pole, or on a wall.
