Repeater application

Repeater Application:

Repeater is to provide a rf High Power GSM RF Repeater,900 rf Band Selective cellcular Repeater booster/ amplifier dio coverage in a flexible and efficient way. Among the things with reference to the design it can be difficult to spread coverage all the way into side isles, narrow hallways, several storys, combined with different building materials. More over, if there are many people constantly moving, for instance in shopping malls, and the demand for coverage varies from one spot to another as well as during the day and during the week, satisfying the growing demand for capacity becomes a challenge. The same storys can been occurred in some villa group, Subway, Speedway, etc. So the repeater can gives you the optimal solution.

To expand signal coverage of fill signal blind area where signal is weak or unavailable.

Outdoor: Airports, Tourism Regions, Golf Courses, Tunnels, Factories, Mining Districts, Villages etc.

Indoor: Hotels, Exhibition Centers, Basements, Shopping Malls, Offices, Packing Lots etc.

It is mainly applicable to such case:

The repeater can find an installation place which can receive pure BTS signal at strong enough level as the Rx Level in repeater site should be more than -70dBm; And can meet the requirement of antenna isolation to avoid

self-oscillation.

FAQ

A.Professional Solutions

Q1. I live in a rural area. Rather than having a second phone line for work, I'd like to use my cell phone, but it only works outside.

A. Signals in many rural areas are marginal and cannot penetrate the walls of your home. Kingtone repeater can be easily deployed to provide coverage throughout your house. In a home, the donor unit is generally deployed outside – for example, under the eaves. Because it is more sensitive than your phone and is mounted higher up, it can usually detect signals that your phone can't. The coverage range of 15,000 to 50,000 square feet (2,000 to 4,600 square metres) is adequate for most homes.

Q2. When I'm at the cottage, I'd like to stay in touch, but if I publish my cottage number, everyone will call. I'd like to just use my cell phone. Can you help?

A.Signals in many cottage areas are marginal and cannot penetrate the walls of your cottage. Kingtone repeater can be easily deployed to provide coverage throughout your cottage. In a cottage, the donor unit is generally deployed outside – for example, under the eaves or on a utility pole. Because it is more sensitive than your phone and is mounted higher up, it can usually detect signals that your phone can't. The coverage range of 15,000 to 50,000 square feet (2,000 to 4,600 square metres) is adequate for most cottages.

You get the privacy of your cottage and the convenience of your cell phone. Just remember to turn it off sometimes!

Q3. I'm a production manager in a factory, and no cell phones work inside. I spend most of my time in a couple of spots. Can you help?

A. Factories and warehouses with lots of metal construction often have poor signals. While these buildings may be large, the employees are generally located in only a few areas.

Kingtone repeater can be easily deployed to provide coverage in those spots. The donor unit is deployed on the roof and connected to a coverage unit inside. The coverage range of up to 100,000 square feet is adequate for most trouble spots. Multiple units can be easily deployed to cover office areas and other working locations.

Q4. No cell phones work in the parking garage. While many employees carry cell phones for safety, the phones aren't useful in any of the high-risk areas.

Kingtone repeater an provide coverage in parking garages above and below ground. That's useful for emergencies, and it removes the irritation of calls being dropped when you park your car.

The donor unit is placed where it can detect a signal (this might be outside or in a stairwell). It is connected to the coverage unit, which is placed in the centre of the garage up to 245 feet (75 metres) away.

Q5. I work in an office building with no outside access. The windows don't open, and I can't get to the roof. How can I install?

A. Kingtone repeater can be deployed completely within your office. It is the only in-building in-building solution.

The donor unit needs to be placed somewhere where it can detect a signal (this might be beside a window or the outside wall). The coverage unit is then placed roughly in the centre of the problem area. Ideally, the two units are separated as much as possible.

For esthetic purposes, the entire system can be placed above the ceiling tiles.
