Suntsu Indoor Antennas

All antennas work to change energy between two forms – electromagnetic waves (like radio and TV signals) into electrical current and vice versa. An antenna can transmit and receive information as an electromagnetic wave or signal. Indoor antennas tuned to a TV broadcast frequency will receive EM Waves from the broadcasting station and convert them into sound and pictures on your screen.

Implementing indoor antenna into your application involves:

• Frequency – each antenna works inside a frequency band. 2.4– 2.5 GHz is typical for WiFi applications.
• Polarization – an antenna works in combination with a ground, and antennas are horizontal or vertical in polarization.
• Power gain (compared with an isotropic radiator) in dBi, gives an idea of the strength or range an antenna covers.

Indoor antenna design covers:

• Coverage and capacity – these are not the same.
• Scalability for future addition and growth.
• Specific requirements – bandwidth and regulations.
• Antenna direction linked to purpose.
• Data rates supported by a client device.
• Potential obstructions of the signal.
• Consequences of a breakdown in communication.

Deploying indoor antennas to create effective WiFi or another network involves:

• Site survey to establish the best points to deploy your antenna for coverage and density.
• Check power compliance is compatible with your indoor antennas.
• Physical mounting for omnidirectionality and avoiding obstructions to signals.
• Consider the distance between indoor antennas for desired density and performance

• Indoor antennas: Indoor antennas are inside buildings (modems, boosters, hubs, and networks) and devices. Outdoor antennas are fixed in outdoor locations and are typically larger scale, but they can be small.
• Outdoor antennas: Outdoor antennas are temperature resistant, waterproof, and rugged because they withstand weather impact. Indoor antennas don’t need weatherproofing.

The factors in selecting which antenna work for your solution include:

• Signal strength is particularly relevant if you want to pick up TV and radio channels. These are broadcast from transmission towers and require careful orientation of an indoor radio antenna.
• Size – the size of an antenna relates to the frequency signal, and the size is essential as part of the design process and installation. An indoor TV antenna must match the signal from the TV broadcasting station.
• Application – the reason for and type of communication between devices will impact the size and type of antenna that works best. A 2.4 GHz indoor antenna is useful for boosting WiFi coverage in your home or office.
• Budget – an antenna that works across a shorter distance tends to be less expensive, so you want an antenna that has an adequate but not excessive range for your application. Selecting a long-range antenna for a short-range application costs more but doesn’t add more functionality.

Indoor antennas are the best options for:

• Creating a WiFi network to cover a whole building or area, so everyone is connected wherever they are or work.
• Extending an existing WiFi network with a high-performance indoor antenna and a clear line of sight, you can extend your WiFi into another building.
• Boosting signals – better TV and radio reception, better phone communication, or enhancing the quality of any other transmitted signal.
• Providing WiFi to customers or clients in a coffee shop, public square, or train carriage. Providing WiFi for visitors is now an essential part of a business.
• Buildings that cannot use an outdoor antenna must rely on indoor antennas for all their communication and media needs.
• Remove the potential hazard of cables in an office or business place or provide networking in areas where you need mobile working.

You can increase the quality of reception of signals for your best indoor antenna by:

• Orientating the antenna in the direction of the signal for radio and TV broadcast channels.
• Avoiding obstructions – a clear line of sight gives a better signal; walls, trees, and other objects reflect radio waves.
• Ceiling mounting is helpful because it avoids most obstacles between devices and gives better coverage in an area.
• Metal interferes with EM waves, and it is best to have some distance between your indoor antennas and metal objects like radiators.
