How does the 'fixed-wireless' network work?

The Subscriber Module (SM) is the subscriber termination unit (like a cable or DSL modem). SM's are generally located on the roof where they can see the tower site. Multiple Access Points (AP) at our towers can handle hundreds of customers. The SM is connected to your computer or router via a single Cat 5 (or Ethernet) cable and powered via an AC power adaptor.

What is the range of the system?

The range of our system is determined by a number of technical and environmental factors. Additionally we can employ a variety of specialty antennas to increase the range and signal level in various locations. Some of the technology we employ does not require strict line of sight to the tower. Typically we can cover over 10 miles from each of our 30 Towers in the area. We have created a wide variety of survey tools which allow us to predict if service may or may not work at a specific location, however, there is always a chance our installer will get on site and find that there just isn't the appropriate signal level to provide service.

What exactly is involved in the installation of Plexicomm's service?

Our office will schedule an install for your home or business location. You will not be charged we if we cannot make the initial connection. Using a test instrument, our installer will test the link quality before installation. If the link tests OK, we will collect any installation fee at that time. The antenna will be installed and a small cable is run into the interior of the premises and connected to a small power supply box (A Power over Ethernet - or PoE Injector). Your computer and/or router are configured and you're all set. If you have multiple computers we ask that you have a router purchased and at the premises at the time of the install. If you have rented a router from us it will be provided at the time of install.

This is "wireless"? Why do you have to drill a hole through my wall?

The Wireless service we offer is considered wireless because the signal between you and us requires no physical cable stretched from the Plexicomm data-center to your home or office. In order to attach our antenna to your home or office network in the most cost effective and efficient way possible we do need to connect the Antenna with a cable to the power supply and your network.

I already have an e-mail account and don't want to change my e-mail address.

Many email providers such as Gmail, Yahoo, Hotmail, etc do not get changed based on your Internet provider. You will be able to continue to access your email on these systems.

If your email is provided by your ISP you will lose that address when you change services. Some companies will allow you to opt for email forwarding for a short period of time. If you lose your email this way we can provide you with one!

In the case of services such as AOL, they do have a "Bring your own access" product which allows you to keep their service for an additional fee.

My information is being sent over "airwaves", is this safe?

This technology is also VERY difficult to intercept and decrypt without expensive equipment. Unlike Wi-Fi or Cellular technology where the signals are transmitted in all directions, our signal is sent over a refined, elevated sector of airspace. It would be impractical to attempt to intercept data in such a manner, and even then it would be encrypted and disjointed.

All traffic from our transmission site to your PC is transmitted with a proprietary protocol that is not easily intercepted. This adds an equivalent protection level to being wired directly into a network.

I am within your coverage area but was told I cannot get service, why?

The technology used to provide wireless service uses microwave frequencies to communicate. These frequencies require "Line of Sight", in other words, the antenna needs to be able to "see" the transmission site to be able to communicate.

Trees, buildings, topography and other obstructions can prevent a signal from getting to you. We are always adding sites to better service "shadowed" areas, and we will retain your information and contact you when we can provide a solution.

In some areas we do employ a type of technology that is more dependent on Directionality (pointing in the direction of the tower) than full Line of Sight ("seeing" the tower). However, even in those cases we have standards of quality that have to be adhered to, and there are just some cases where the signal levels are not strong enough.

Is there a limit on how much data I can transfer per month?

No. There are no bandwidth caps or limitations.

How do I connect multiple computers to the connection?

Plexicomm Field Technicians will install a single Ethernet connection inside your home or office. If you have more than one computer or Internet-ready device you will need to purchase your own router or rent one from Plexicomm. The router acts as a splitter, allowing up to four computers to be plugged in directly and many more wirelessly if the router is Wi-Fi enabled. To connect to Wi-Fi your computer or other Internet-ready device will need a wireless card installed.

Will weather affect my service?

As a general rule weather and even severe storms will not cause degradation in the service level.

How is Plexicomm's 'fixed-wireless' Internet access different from a dial-up service?

Unlike dial-up, our service is always on. This means that there is no dialing, no waiting, and no need for a second phone line. In fact, our service doesn't require a phone line at all. There is also a dramatic difference in speed - Plexicomm is over 50 times faster than dial-up service and in many areas over 150 times faster!!

How long will it take to set-up service?

We can typically have service installed within several days of placing an order. It will typically take about 2 hours to complete the site survey, installation and quality test of your Plexicomm Internet installation.
