CASE STUDIES

All of the following scenarios are real life examples of how our clients have used our phone systems. Think of how you could adapt one of these scenarios to your application.



PROBLEM

One of our clients owns a USA based telemarketing business located 2 kilometers (about 1.2 miles) from the Mexican border.  The cost of labor in Mexico is far less than in the USA and the business owner wants to take advantage of the low labor cost.  However, if his telemarketing force is based in Mexico the owner would have to pay international long distance every time his employee made a call from Mexico to his USA customers.  What to do?
SOULTION
An FCC certified 25 line long range phone system was installed at the business owner's USA telemarketing facility.  The remote end of the system is located in Mexico, where his new telemarketing staff resides.  The owner saves quite a bit of money with his new low cost labor force.  There is NO CHARGE  for international calls because even though the employee is dialing the call from Mexico the call is being placed from the USA.



PROBLEM
A Nigerian diplomat has a house atop a large mountain located 35 kilometers from the nearest phone line.  The house offers great privacy, views, etc, but no phone.  The local phone company would run phone lines to him, but the cost is over US$100,000. The owner would like to have landline quality phone service in every room in the house, but with the amount of money the phone company wants to run lines it is unfeasible.  Is he stuck with his expensive satellite phone which offers marginal service?
SOLUTION
A 4 line data capable system was installed at a cost of under $17,000.  The system uses telephone lines located 40 kilometers away and a multiplexer was installed to allow fax/internet access. The owner no longer worries about per minute charges on his satellite phone, which is now a paperweight.



PROBLEM
A foreign government, who shall remain nameless, routinely has several large ships anchored 10-60km off shore.   Currently this government uses INMARSAT satellite phones for communication, and they use the phones a LOT. The sat phones work great, but you would not believe how high the bills are.
SOLUTION
A 30 watt point to point system with high gain antennas get the job done.  All calls made on the ship are placed from a land line on shore, and billed at the rate of $0.  Faxes come through over twice as than they do with a satellite phone.  The government is happy, that tax payers are happy, everybody is happy.  The sat phone company is probably not too enthused.



PROBLEM
Kenya - Customer has a ranch 70 kilometers from the nearest phone line.  Currently uses a satellite phone at a cost of roughly $8/min.  What other choice can he possibly have than to pay $8/min?  After all he is in the middle of the bush and there are no phone lines for 70 kilometers.
SOLUTION
A XL7200 system was configured at a cost of under $4,000.  Not only does our client have clear voice communication, he also has fax and internet access.



PROBLEM
Executives at a large USA car dealership needs to stay in contact with seven key employees within a range of about 2 kilometers.  They are using Nextel Units (Nextel offers wireless/2-way radio service in the USA) at a total cost of about $700/month.  The owner does not want to pay over $8,000 per year on phone bills.
SOLUTION
A 910R system configured with 7 handsets.  Monthly Nextel bill of $700 eliminated.  Our system paid for itself in 3 months.  The users now enjoy full duplex 2-way radio communication (both people can talk simultaneously) as opposed to simplex (only one person can talk at a time) with the Nextel.
 
Answers to Frequently Asked Questions


How can a phone have such a long communication range?
These phones make use of different technology than conventional cordless telephones.  The frequencies on which they operate, combined with the wattage, communication standards, and external base station antenna allow for extremely long range communication.

Why haven't I heard of these phones before?
Long range phones have been around for decades. They are not sold in US stores primarily because most are not FCC certified. We have been selling these products since 1994, with great success.

How difficult are these phones to set up?
Our entry-level models simply plug into your normal A/C outlet and standard RJ-11 telephone jack. You simply unpack the phone, plug it in, and charge the battery. Our higher-end models come with an external mount antenna. This antenna is mounted on a roof or other high altitude, and plugs into the phone's base station using coaxial cable (similar to TV cable). All mounting hardware, cable, and detailed instructions are included. Antenna installation time is estimated between .5 - 1.5 hours.

Why can't some of these phones be used in the USA?
Some phones are not FCC certified and can not be used in the USA. Sales to US customers (other than military, government, or law enforcement) are for EXPORT ONLY. The main reason that these phones are not FCC certified is that they exceed the maximum power requirements mandated by the FCC and/or make use of frequencies commonly used by non-telephone equipment. The use of a long range phone could potentially interfere with the operation of this non-telephone equipment.

How good is the sound quality?
When within adequate range of the base station, sound quality is exceptional. You will not notice a difference in sound quality between our phone and any other high quality cordless phone. Some of our phones are digital, providing voice quality similar to a corded office phone. When approaching fringe areas, you may experience static as with any cordless phone.

Can someone eavesdrop on my conversation with a scanner?
Many of our phones include a commercial grade scrambler. If a scrambler is not already integrated with the system, you may add one as an option (in most cases). Some systems, such as the 910R, are digital. Digital transmission is inherently safe against eavesdropping. If call security is a concern, please consult us so we may recommend an appropriate system.

What if I don't have AC power at my remote location?
If A/C power is not available, we can set the remote unit to run from solar, wind, hydroelectric, gas, battery and more.

You list a maximum range. What range will I get in my application?
Range can vary greatly from one application to another. A phone designed for a range of up to 50km in open space may deliver only 10km in a mountainous environment. It is important to let us know the environment where your system will be used so we may select an appropriate frequency/power output/antenna combination. If you have line of sight conditions and your antenna is set up properly, you can expect close to the maximum range. If there are obstructions such as buildings and thick foliage, the range will be reduced. There is no "minimum" range.

Will these phones cause interference with other cordless phones?
Our phones are specifically designed not to interfere with one another. However, our phones may cause interference with inexpensive cordless phones currently in use at the base station location (where the telephone line is). If this is an important issue, speak with our technicians to determine how this type of interference can be prevented. Additionally our phones may potentially interfere with other electronic devices, such as computer monitors, and the older style UHF televisions. Our phones will not interfere with satellite dishes or cable.

Can I attach your phones to my existing business telephone system (PBX)?
In many cases - yes. If you can plug an "off the shelf" analog phone (like you would buy at an office supply store) into your PBX, our phones will be compatible. You can assign our phone an extension, and most features of your PBX will be available on our phone. If you can not plug an analog phone into your PBX you may be able to obtain an analog card from your PBX manufacturer. The analog card would enable you to use our phones on your system. If you are unsure, ask us.

Can I mount the external antenna inside my building, or on the ground?
All of our antennas are designed to be mounted at an elevation of at least 5 meters above ground level. There should not be any obstructions for at least 4 meters on all sides of the antenna. The antenna needs to be properly mounted for optimum performance. If the mounting instructions are not followed the range will be reduced. Some of our phones may be used without an external antenna, or with a window antenna, but the maximum range will be greatly reduced.

What type of warranty do these phones come with?
All phones come with a full 1 year parts and labor warranty. After the warranty period has expired, phones are adjusted and/or repaired for a nominal charge. All warranty work is handled through ACS' USA facility.

Where are these phones made?
Taiwan
