About Us

Our shop is located at the Port of Stockton in the old San Francisco Naval Communications Headquarters building. I have been building and servicing two way communications systems since 1969 when I graduated from Ranken Technical College and entered the US Navy as a Communications Technician. We built and maintained two way radio systems for the Seventh Fleet. After serving a six year enlistment, I mustered out at Treasure Island and began working at the Motorola Service Center in San Francisco. Forty plus years later, I am still building and maintaining two way radio systems.

Our Experience

I've been installing and maintaining radio systems for over 50 years. I enjoy answering questions and helping my customers get things done on time and under budget. There are Pros and Cons for each type of system. By going over all of the options, a good Consultant can find that sweet spot where the needs are met and the budget is maintained.

Our Values

We treat our customers like we want to be treated. I was taught to "Use it up, wear it out, and eat it all". Government waste is wrong and living within your budget is right.

The only thing constant is Change

1950s: Technology Analog Land Mobile Radios

Two-way radios have been around in analog form since World War II. It is simple, ultra reliable, and inexpensive. Every manufacture makes analog radios. The ultimate (KISS) Keep It Simple Solution. These systems are best for agencies that do not require encryption. Typically, portable radios can be purchased for under $500.

1985 Technology: Trunking Systems

In the 80's, before Cellular phones became available, there were many Public Safety and Commercial users wanting additional frequencies. The solution for this was Trunking systems. Much like an office phone system, e.g., 4 lines being shared by 15 office phones. Similarly, the LMR Trunking systems would have 20 channels shared by 200 radio talk groups. Usually, there were enough channels available to be shared. However, when major events would take place, like a visit from the President, these systems would get overloaded and the emergency traffic could not get through. Another down side to trunking systems is that most of them routed all traffic through a single audio or digital switch. First rule of Public Safety Communications is never allow a single point of failure in your Emergency Communications System. Adding Trunking to a portable radio typically adds another $1000 to its price.


1990s Technology: Digital Two-Way Land Mobile Radio

In analog systems, the signal is clear near the base station and gets progressively noisy the farther away you are from your base station. In digital systems, the signal is clear until you reach the edge of your coverage area, where your signal abruptly cuts off. The coverage area doesn't increase significantly, but it sounds clearer until it stops working. The down side is that each manufacture designed their own proprietary digital radio system, thus competition was eliminated. Typically, these portable radios can be purchased from $800-$1000.

2000 Technology: P-25 Digital Two-Way Land Mobile Radio

The Federal Government tried to establish a standard for all manufactures so there would be some competition. This was called Project 25. In an effort to prevent competition, some manufactures again added proprietary add-ons, such as ADP encryption or linear simulcast to conventional systems, that were not approved in the P-25 standard. Again, if you purchased one of these radios, you were locked into purchasing from only that manufacture. Typically, these portable radios can be purchased for $1500-$3000.

2012 Technology: Multi-Band Two Way Land Mobile Radio

In the 50's and 60's, all VHF (150-170 MHz) frequencies were used up. Technology advanced to the point in the 1970's that UHF (450-512) frequencies became available. Soon these frequencies filled up as well. The next step in technology brought about 800 MHz and soon after 900 MHz. Even though this allowed for more channels, radios were not capable of operating in multiple bands; a VHF radio could not talk to a UHF radio. Known as the Silo effect, a Fire department operating on a VHF frequency could not talk to a Police department radio using UHF frequencies or (800/900 MHz). A couple of manufactures came out with multi-band radios allowing us to program two or more bands into a single radio. In essence, they packaged multiple radios into single units. Typically, multi-band portable radios sell for $5000-$9000.


2018 Technology: First Net

 First Net is up and working now and that gives us more options for Public Safety communictions.  A First Net capable phone with a push to talk button on the side can have 100 talk groups with up to 250 phones per talkgroup for all of your routine communictions needs.  It can also have talk groups that interface with your existing conventional radio systems.  This allows you to hear and talk on your Public Safety radio repeaters through the phones anywhere there is AT&T cellular coverage.  (Nationwide Coverage)  The sound from these phones is crystal clear and as loud as a typical Public Safety grade portable radio.  The Economy of Scale  has brought the cost of these phones down to about what you would pay for a replacement battery for your old portable radios.

Check out the Kyocera Duraforce Pro for admin folks and the virtually industructable Sonim XP8 for the Fire Fighters and Police Officers.  You can order both through Enterprise Communications.

Lets Do a Needs Assessment For You "Budget vs Coverage"

One size never fits all. AT&T's existing EPTT "Enhanced Push to Talk" system works very well for most Non-Public Safety customers now. For Fire, Police, and Medics, the First Net systems are now on line in 2018. We recommend starting with a few First Net phones to compare coverage and quality. Only when you hear first hand the clarity and greatly enhanced coverage area, will your fully understand the benefits of First Net. For larger agencies, we can integrate the First Net phones into your existing two way radio system, giving you a redundant path and greatly enhanced coverage area. For smaller agencies with tighter budgets, the First Net system may be the only communications system you need.
