GSM antennas expand the reach of GSM devices such as cellphones and smartphones (such as the ubiquitous Blackberry). They are also commonly used by fleet operators to track vehicles. The most popular mobile standard in the world, GSM is used in cellular networks in more than 200 countries. Whether you're looking to boost your reception on the road, need to expand the reach of your business operations or are considering a GSM device, knowledge of GSM antenna key terms will go a long way.

GSM

GSM, or Global System for Mobile communications (formerly Groupe Special Mobile), is used by more than three billion people across the world. Before you can understand GSM antennas, you have to understand GSM.

Dual-band, tri-band, quad-band

Some GSM devices use two frequency bands (dual-band), some use three (tri-band) and some use four (quad-band). Before you buy a GSM antenna, learn about how many bands your devices use and shop for antennas accordingly. Also, take into consideration if you're likely to travel, as different countries utilize different GSM frequencies.

I recommend: The Travel Insider presents a short discussion on the different band options available with common GSM devices.

Country frequency

GSM operates at different frequencies in different countries. For example, in the U.S., it operates at 1.9 GHz and 850 MHz. Before you buy a GSM antenna, make sure it's appropriate for your country. If you travel, take the frequencies of countries you visit into consideration, too.

I recommend: AllWorldCellPhones has a great chart that lists country frequencies.

Parabolic and parabolic grid

Parabolic and parabolic grid antennas are shaped like dishes to concentrate signal reception and transmission in a specific direction. Grid antennas, which are made of grid-like material, are more resistant to wind than normal parabolic antennas.

I recommend: See examples of parabolic and parabolic grid antennas and learn more about them at Stella Doradus.

Omni-directional

Omni-directional antennas are equally sensitive from all directions. They are most commonly used where signals will be coming from all directions.

I recommend: BinaryWolf.com describes the characteristics of omni-directional antennas.

GSM/GPS tracking

Businesses that want to track their vehicles commonly do so with GPS antennas that utilize GSM. These GSM/GPS systems allow owners to track vehicles in real time.

GSM, or global systems for mobile communications, is an important part in cell phones and other equipment that relies on global satellite and positioning systems to connect mobile devices. The GSM network needs three major components to work: the base station, network subsystem, and hand-held units. All these devices rely on GSM antennas to function. Whether you use traditional communication methods or something non-traditional, such as spy equipment, the GSM antenna is one of the most important parts of the system.

Offering GSM antennas to your customers means you will also have to offer plenty of information on the products, in addition to installation and repair services. In order to draw in customers, address their needs by considering the following:

1. The price of the GSM antennas you offer

2. The range of GSM products you offer

3. If there are any perks, such as installation, repair, or extra warranties on the products

Choose a variety of GSM antenna products to offer your customers

GSM is a system that needs three parts, and there are different GSM antennas for each of them. For the hand-held devices, there are many products available to suit your customer's needs. And for base stations and substations, there are specialized antennas for made for broader use, and those that look good aesthetically.

I recommend: Preserved Palms offers GSM antennas you can easily hide in palm trees without damaging the tree, so you don't have to see an unsightly antenna. And you can find multi-use GSM antennas at Multiband Antennas.

Offer customers used and custom GSM antennas

Used GSM antennas are great to offer because customers like to save money. If the equipment is still in good working order, the savings on used equipment can be big. And if you find that customers want more than the standard available equipment, it may be time to begin offering custom GSM equipment to give them what they need.

I recommend: Electronics Manufacturers offers great deals on used GSM antennas. You can find custom GSM antennas from the R. A. Mayes Company.

Provide GSM antenna repair and installation services

Choose GSM antennas and systems that are easy for your customers to install. This way, they will be more willing to buy the product. But you want to offer your customers installation, go for it. Most of the equipment is easy to install with the instruction manual. You can also offer repairs to GSM antenna and equipment by having an employee take a simple repair course.

I recommend: San Jose Technology offers GSM equipment that is easy to install. And if you need to train employees to be experts on GSM antenna repair, send them to GSM Repair Course Online.
