wireless business Internet FAQ

Q: What is Fixed Wireless Internet?

A: Watch our Wireless Demo to see how Fixed Wireless Internet works.

Q: Does rain affect the reliability of a fixed wireless connection?

A: At 5.8 GHz, the UNII band frequency we use, the attenuation of the radio signal due to rain is insignificant and so rain has no practical impact on the link reliability at all.

Q: What about line-of-sight? Don’t you need an unobstructed path from one end to the other? Doesn’t that restrict deployment?

A: Yes, you do need line of sight from both ends of every fixed wireless link in the UNII bands – and in all other microwave bands, for that matter. Generally this is not a problem as the base stations are deployed on the roofs of high-rise buildings, which have a commanding view over adjacent terrain. In some cases, trees and other buildings may cause obstructions, which should be overcome using a mast extension at the user’s location or with a repeater.

Q: What about security? Can my wireless data be intercepted?

A: No. The TelePacific wireless network employs more encryption and levels of security than even a T1 because we don’t use WiFi equipment (which has well known security issues). Every customer has an individually provisioned point-to-point circuit that is only capable of communications between the client and our network. No broadcast technology is used (i.e., WiFi) that would allow unauthorized snooping or eavesdropping.

To further enhance security, TelePacific wireless employs directional antennas throughout the network to ensure that wireless signals are only received at the locations where they are intended to eliminate interception.

Finally, the wireless traffic itself is encrypted over the air via proprietary encryptions schemes employed directly in the radios.

Because of these advanced security features, our wireless segment is actually more secure than a standard T1, which have no encryption.

It is still important to recognize that Internet access over any technology (T1, DSL, Cable, and fixed wireless) creates an open doorway to your network. A firewall is recommended to prevent unauthorized access into your network from the Internet.

Q: Isn’t there a major difficulty with roof access for wireless systems? What do you do to get access to the roof if the end-user doesn’t own the building?

A: Our customer-premise equipment can be installed on most any location and qualifies under FCC rule 47 C.F.R. Section 1.4000, as amended, which prohibits restrictions that impair a person's ability to install, maintain, or use a fixed-wireless service antenna. The rule applies to state or local laws or regulations, including zoning, land-use or building regulations, private covenants, homeowners' association rules, condominium or cooperative association restrictions, lease restrictions, or similar restrictions on property where the user has ownership or a leasehold interest in the property. Additional information can be found on the Federal Communications Commission website at http://www.fcc.gov/mb/facts/otard.html.

Q: Isn’t there a potential problem with interference in the unlicensed bands, such as UNII? What happens if another system is installed nearby and causes interference to the wireless connection?

A: It turns out that there is a greater perception of interference problems than actual interference problems! We have more experience than anyone in pioneering the deployment of tens of thousands of reliable fixed wireless systems in unlicensed frequency bands around the world. The first issue is that the system must be well designed, with directional antennas and frequency channel selection: any fixed wireless system that is poorly designed, licensed or unlicensed, will be unreliable. The second issue is that most cases of interference in unlicensed bands have occurred at the densely populated lower ISM frequencies: 900MHz and 2.4 GHz, where there is less path attenuation and directional antennas more difficult to deploy because they are much larger. Our staff have not experienced any interference problems in the higher 5.8 GHz ISM or UNII bands. Additionally, there is an FCC requirement that unlicensed equipment must not cause interference to any other systems: see FCC Rules, Part 14.247 and 15.401. In practice this means that there is a huge advantage to the first user in deploying his system. And typically, the new user would experience reverse interference himself when he installed a system causing interference to an existing user. So, the new user would not be able to successfully install his system and this would lead to the parties working out a mutually cooperative solution.

Q: Is this faster than DSL?

A: Many businesses today need fast access both upstream and downstream, and most DSL connections cannot support symmetrical access. Our wireless Internet service supports symmetrical broadband with the flexibility to increase service levels in the future.

Q: How long does it take to get my service installed?

A: Because our wireless technology is not dependent on, or limited by, your local phone company and its copper wires, service can be installed in as little as one day.

Q: If I am an ISDN PRI, DSL or T1 access user, how difficult is it to switch to a wireless service?

A: It's fast and easy! Our wireless Internet can simply plug into your LAN or computer via a standard Ethernet (10 BaseT) connection and will handle all of your IP addressing and allocation.

Q: How can I scale-up to meet my increased bandwidth needs and how difficult is it to do this with wireless service?

A: It's easy! Contact one of our sales representatives and they can help you find the best service for your business. Typical upgrade choices are to upgrade maximum bandwidth to 4, 6, or 10 Mbps. We have high bandwidth options of up to 100 Mbps.
