Wireless products, applications and services vary significantly by frequency band. Frequency bands are defined and authorized by the FCC for specific purposes and applications. For example, VHF and UHF frequency bands are typically used for paging, voice and low speed data transmission, while L-band (1-2 GHz) and S-band (2-4 GHz) frequencies are often used for broadband applications. In addition, there are many other unrelated wireless services such as radio and television broadcasting, telemetry, microwave links, location services, wireless PCS and other services spread across these frequency bands. For this reason, numerous manufacturers, specializing in different areas are necessary to service and fulfill the needs of the wireless marketplace.

This diversity among manufacturers has resulted in  an abundant ecosystem of equipment vendors and  service providers, each with tailored solutions for  different types of spectrum. For example, a company  like Airspan, a leading provider of wireless broadband solutions, supplies solutions for transporting high speed data, video and voice. Fortunately other competitors, such as Redline and Aperto Networks, also design and manufacture wireless broadband equipment insuring prices remain competitive.

Another example of equipment affordability through competition exists in the 217-220 MHz AMTS band. This band has been allocated for maritime communications, and as a result a mature ecosystem of product offerings has evolved. However, because this band is between the traditional UHF and VHF bands a more limited selection of equipment is available. Tait and Motorola are the primary suppliers of voice radios in this band - a competitive ecosystem, albeit limited.

The effect of a very limited ecosystem of suppliers can also be seen in the 217-220 MHz band, but only when users pursue more unique applications, such as telemetry. Telemetry equipment and solutions are commonplace in traditional UHF band of 150-174 MHz, however, the 217-220 MHz band has typically been used for voice, and radios capable of transporting data are not common. In fact, a single radio capable of supporting data/telemetry is available from multiple vendors, but due to low demand, cost per radio can be measured in thousands of dollars. Therefore the 217-220 MHz telemetry market would be considered a niche.
