(FAQ) Frequently Asked Questions

Q1. Why Bridge with Wireless Technology?

Businesses often have various operating units scattered over a number of locations.

Expensive headache for to install wired WAN connections to all these locations.

Wired connections involves leasing T1 or fractional-T1 data links from the telephone company and purchasing expensive terminal equipment.

Lowest data speed/$ ratio of all alternatives

old tired way of using a T1 wired line


Q2. Why use the Wuta Plus Wireless Bridge? FAST (1.5 Mb/s) and with no monthly leasing or air-time charges

No expensive T1 terminal equipment (CSUs/DSUs)

Wuta Plus provides all bridging functionality

No radio licensing hassles

Point to multi-point capability

Secure

the only way to go - wireless!


Q3. How is a Wuta Plus Wireless Network configured?

A Wuta Plus "Master" station is established on the main network

Can provide wireless bridging for up to 127 remote ethernet networks


Q4. Applications?

Factories, Production Plants & Mines Customers: Bridging LAN networks between warehouses, maintenance sheds and the main office.

Schools, Sports facilities, University Campuses. Bridging dispersed schools, sports facilities and different departments.

Commercial Buildings: Bridging networks across the road to a satellite office.

Internet Service Providers: Bridging internet access points and setting up a POP (point of presence) in neighbourhoods.


Q5. What radio frequency do we use?

Direct-sequence spread-spectrum technology (interference resistant)

Operates in the ISM band -902-928 MHz North America and 2.4 GHz International.

Shared band that does not require an RF site license for spread spectrum. (in most countries)

Wuta Plus operates at 915 MHz and uses 16 MHz of bandwidth


Q6. How far can we go?

Up to three kilometres for line-of-sight links in urban areas (limited by interference from other users and FCC and IC regulations on system gain)(could easily go longer).

Up to 10 kilometres for line-of-site links in low-interference rural areas.

Directional antennas (6 element yagis-9dBd or higher) are needed for all links over 2 km.

Directional antennas focus transmitted power in the direction of the receiver.

Directional antennas suppress interference from other users in the the same band.


Q7. What is a line-of-sight?

that crazy freznel zone

Keep that Fresnel zone clear.

2 km: Fresnel zone = 13m

10 km: Fresnel Zone = 28m


Q8. Can I use directional antennas?

Maximum allowable gain 9dBd. (27 dBm + 9 dBd - cable losses <36 dBm) in North America

Antennas must be supplied by Wi-LAN unless customer is RF technician and familiar with IC and FCC regulations.

Cable losses between Wuta Plus and antenna should be kept to a few dB by using quality antenna cable (LMR-400 0.12dB/m


Q9. What about GROUNDING of outdoor antennas?

The correct grounding of outdoor antennas, cable and support structures is critical for both lightning protection and noise suppression. Surge arrestors should also be used at the point of cable entry into the building.


Q10. What computer networks can we bridge with the Wuta Plus?

Any computer network that uses ethernet with either a:

  1. 10baseT interface (telephone jack type connector) (twisted pair)
  2. 10base2 interface (BNC connector with coaxial cable - also called "Thin-net"


Q11. How secure is the Wuta Plus radio link?

Data is inherently secure because

  1. we employ "spread spectrum" technology. Data is "spread" by a code at the transmitter, and this code is needed at the receiver to "despread" and recover the data.
  2. the data is also scrambled irregularly in time at the transmitter.

The only device that can correctly receive a Wuta Plus radio signal is another Wuta Plus !

On request, we can assign a customer a data packet security code. This code is set at the factory and cannot be altered by the user. With this code, only that customer is able to receive transmissions from his Wuta Plus with the same code.

Wuta Plus Networks - Total security


Q12. Can I use this bridge for phone telecommunications?

The Wuta Plus Ethernet Bridge is used for ethernet data communications and is not designed to be connected to a PBX system.

However, Internet phone systems are possible to use.


Q13. Are repeaters available and why should they be used?

The Wuta Plus can be used in a repeater situation where line of sight between antennas is not possible. A building may be in the way or a situation may happen where transmission is required over a hill.

The Wuta Plus repeater is a store and repeat bridge link. Because of this the speed is reduced to approximately 750Kbits/sec for repeated links.


Q14. Do I have to pay monthly fees for use of this Bridge?

Absolutely not! This is not a paid cellular of phone line leasing time based system. Once the Wuta Plus system is in place there are no ongoing costs.

24 hours a day, 7 days a week, 52 weeks a year - no time costs!


Q15.How difficult is the setup for this system?

The setup is extremely easy.
[1] set up an ethernet connection to the computers to be linked with using ethernet cable.
[2] when full ethernet connection is made, the ethernet cables from the hubs or ethernet card is connected to the appropriate 10baseT or 10Base2 connection in the back of the Wuta Plus Ethernet Bridge.
[3] the antennas are attached via antenna cable and connectors.
[4] the antennas should be properly grounded by a certified radio technician if placed outside.
[5] Done!

There is no software or drivers that need to be installed on the individual computers for the Wuta Plus! The unit is transparent to the users.
