There are numerous wireless communication methods for electronic LED signs. The primary advantages that wireless has over traditional hardwire communication options are the quickness to and low infrastructure cost for implementation. Wireless options for LED signs usually only require the communication equipments. While hardwire requires digging up existing pavement and laying down new conduits, which maybe expensive and time consuming. Please, keep in mind that not all wireless communication options are the same. They vary in price, reliability and capability. The following descriptions will provide you with a better understanding of these differences.

DESCRIPTIONS:
Uses radio frequency (RF) modems that operates in 900MHz range. Recommended mostly for outdoor applications. It is very important that there is line of sight between the transmitting computer and the LED sign. Metal structures, trees, water towers, and physical terrain will impede the transmission reception.

BENEFITS:
• Remote access without having to dig conduits in the ground.
• Less expensive than traditional hardwiring if installation cost is factored in.
• Supports transmission distance of up to 2 miles.

CONSIDERATIONS:
• Additional equipment required to support extended transmission distance. 
• Line of sight is required. Weather, terrain, and building can impede transmission and reception.

DESCRIPTIONS:
WiFi is a group of Ethernet devices that complies with the IEEE 802.11 wireless standard, which operates in the 2.4GHz range and can transmit from 1 to 11 megabytes per second. While the transmission throughput is greater, the transmission distance is less than lower frequency RF modems. Point to point access is also know as "ad hoc" or "peer to peer".

BENEFITS:
• Least expensive wireless option due to wide spread support for it.
• Ideal for LED signs located inside, on and/or near the premise, such as a parking lot.
• Supports transmission range of up to 600ft2.

CONSIDERATIONS:
• Each LED sign requires a WiFi LAN box, unless signs are daisy chained in a network.
• Advance IT knowledge maybe required to configure device's IP address and ad hoc setting.
• Vulnerable to computer hackers if not properly implemented.

DESCRIPTIONS:
WiFi devices configured in an "infrastructure" mode can communicate with other devices connected to a hardwire LAN via wireless access points. This setup allows multiple users to communicate with the LED sign.

BENEFITS:
• Less expensive points.
• Uses existing TCP/IP (Ethernet) network and WiFi access points.
• Supports transmission range of up to 600ft2.

CONSIDERATIONS:
• Each LED sign requires a WiFi LAN box, unless signs are daisy chained in a network.
• Advance IT knowledge maybe required to configure device's IP address and infrastructure mode.
• Vulnerable to computer hackers if not properly implemented.

DESCRIPTIONS:
Use GSM based cellular network to transmit data to LED sign. Each GSM modem requires a SIM card that specifies the devices telephone number. Most data throughput is at 9.6 kilobytes per second.

BENEFITS:
• Almost no restriction on the transmission distance, but still dependent on service carriers network.
• Capable of communicating with LED signs attached to mobile vehicles.

CONSIDERATIONS:
• Each LED sign requires a GSM modem and SIM card, unless signs are daisy chained in a network.
• Term contract and monthly recurring fee will apply.
