Digital radios compliant with APCO P25 (APCO Project 25) specifications embody certain fundamental advantages to all, including interoperability. The term interoperability refers to radio equipment in compliance with APCO P25 specs, regardless of the manufacturer, that must be "interoperable" or able to communicate and work together in harmony.

With pure APCO P25 network interoperability, a public safety agency may be able to use one manufacturer for basic infrastructure, another for mobile and portable radios. If those digital radios are BK Radio D Series mobiles and portables from RELM Wireless, that agency is going to save public funds, and/or be able to buy many more APCO P25 radios under the same budget.

APCO P25 interoperability means that all compliant radio equipment of any manufacturer must share the same basic functionality and be capable of working with other APCO P25-compliant equipment. That being so, the cost factor - The RELM Advantage - can make a decisive difference.

More Radio for Your Dollar has a special importance to RELM's BK Radio digital products compliant with the APCO P25 (APCO Project 25) standard:

• Performance requirements are the same for all APCO P25 radio equipment - BK Radio digital radios meet all APCO P25 specs.
  
  
• Still the cost differences can be substantial, with BK Radio D Series APCO P25 digital radios at down to half the cost (or less!) of competitors' comparable products.

One of the first and only manufacturers to develop APCO P25 digital technology, RELM Wireless has engineered advanced next-generation design with singular advantages and practical safeguards:

• Exceptional audio quality and clarity
  
  
• Longer battery life between charges or (disposable battery) changes
  
  
• Easy to use, easy to customize - of real benefit to emergency responders
  
  
• Encryption options for absolute security
  
  
• Rock-solid reliability, the signature quality of BK Radio products

The RELM Advantage in BK Radio D Series digital products - More Radio for Your Dollar - is significant because APCO P25 digital radios are considerably higher in cost than high-spec analog radios. BK Radio D Series digital radios can reduce the costs of migration from analog to APCO P25 digital radio (compared to the higher pricing of competitors' comparable products), resulting in dramatic cost savings.

Going further, RELM Wireless provides the singular option of BK Radio G Series analog radios being upgraded to APCO P25-compliant BK Radio D Series digital radios with the addition of a unique modification device. Planned migration from analog to APCO P25 digital radio systems can be even more cost-efficient over an extended period, with the initial purchase of BK Radio G Series analog radios, then upgraded to BK Radio D Series digital radios at a later time.

RELM Wireless is one of the first and only manufacturers to develop digital product technology in full compliance with APCO Project 25 (APCO P25) specifications. Newer and more efficient digital radio design and production generate the most affordable APCO P25 solutions in the market today.

Plus next-generation design is software-driven rather than requiring add-on hardware components, again resulting in more new features, functions, and enhancements without adding substantial cost.
