Business internet & commercial fiber
PrecisionConnect sources business internet quotes from multiple carriers for offices across Southern California — the Inland Empire, Riverside, San Bernardino, Orange, Los Angeles, and San Diego counties. One serviceability check shows which providers can reach your address, at what speed, and at what price — broadband, dedicated fiber, and fixed wireless. You pay the carrier, not us.

What's the difference between broadband and dedicated fiber?
Most quotes you'll see fall into two categories, and the price difference between them is large. Neither is "better" — they solve different problems.
| Business broadband (cable / shared fiber) | Dedicated fiber (DIA) | |
|---|---|---|
| How it's delivered | You share network capacity with other customers in your area. | A circuit provisioned for your business alone, at a contracted bandwidth. |
| Speeds | Fast downloads, much slower uploads (asymmetric). | Same speed both directions (symmetric) — matters for VoIP, video, backups, cloud apps. |
| Reliability | "Best effort." Outages get fixed when they get fixed. | A service level agreement (SLA) with uptime targets, guaranteed repair times, and bill credits when the carrier misses. |
| Install time | Days to a few weeks. | 30–90+ days, sometimes with construction to bring fiber into the building. |
| Cost | Lowest monthly cost. | Meaningfully more per month — you're paying for the guarantee. |
| Best for | Small offices where a rare outage is an annoyance. | Businesses where an outage stops phones, scheduling, or revenue — practices, logistics, multi-site operations. |
Many of our clients land on a hybrid: broadband as the everyday connection, with a second connection for failover — or DIA at the main office and broadband at branch sites.

What is a serviceability check?
- Serviceability check
- A lookup that determines which carriers can deliver service to a specific street address, what technology they'd use (fiber, cable, fixed wireless), the maximum bandwidth available, and whether construction would be required. Serviceability differs building to building — sometimes suite to suite.
- Fiber Distribution Hub
- Internet travels from the carrier's central office (CO) to a neighborhood fiber distribution hub, then the last stretch to your building. How close that hub is — and whether fiber already reaches it — decides your speed options and whether construction is needed.
This is the single most useful thing a broker does that you can't easily do yourself. Carrier websites will happily take your order and figure out later that they can't actually reach your building. We check first, across our whole carrier portfolio, before anyone signs anything.
Which carriers are in that portfolio? 100+ providers through our master agencies, Telarus and ACS Cloud Partners — the full list is further down this page.

Moving offices or signing a new lease?
This is the number-one reason to call us early. The best time is before you sign the lease — internet options are a property feature, like parking or HVAC, and they vary wildly between buildings that sit a block apart.
- ~90 days out: check serviceability at candidate addresses. Free. If your top choice needs fiber construction, you'll know before you commit.
- ~60 days out: order the circuit and phone system. This puts you inside typical install windows, with slack for construction surprises.
- ~30 days out: schedule cutover. Port your phone numbers, stage the new equipment, and set a move-day plan so the phones ring at the new office on day one.
Already signed and the move is in three weeks? Call us anyway — 951-392-9999. Fixed wireless and temporary solutions can bridge the gap while a fiber build finishes.

Can you replace our phone system too?
Yes. Phones and internet are one decision now — a modern business phone system is software riding on your internet connection.
Cloud phone systems (UCaaS)
Unified communications as a service: desk phones, mobile apps, auto-attendants, call recording, and video meetings, billed per user per month. No phone closet, no PBX hardware to maintain. We size the internet connection first so call quality holds up.
SIP trunking
If you own a phone system you like, SIP trunks replace expensive analog lines and PRI circuits as the way calls reach it — usually the cheapest path if your current hardware still earns its keep.
POTS line replacement
Fax lines, fire alarms, elevator phones, and gate systems often can't just be canceled — codes and compliance apply. Purpose-built POTS replacement devices (typically cellular-based) keep these running at a fraction of what copper lines now cost. See the bill audit page for why copper prices keep climbing.

What about network security and SD-WAN?
For multi-site businesses, we also quote SD-WAN and managed security from the same carrier portfolio.
- SD-WAN
- Software-defined wide area networking. It manages traffic across two or more internet connections — automatic failover when one fails, smart routing for voice and cloud apps, and one dashboard across all your locations.
- Managed firewall
- Business-grade network security run by the provider: threat filtering, content controls, and VPN access for remote staff, without needing an IT department to babysit it.
Not every business needs these. If you don't, we'll say so — a five-person office with one location rarely needs SD-WAN, and we won't quote you things for the sake of it.

How does procurement work with a broker?
- Tell us what the business does. Locations, headcount, phone habits, cloud apps, what breaks when the internet goes down. Fifteen minutes, plain English.
- We run serviceability at every address, across the carrier portfolio.
- You get quotes side by side. Same format, real MRCs, contract terms spelled out — including "keep what you have" when that's the honest answer.
- You pick. The contract is signed directly between you and the carrier. We never resell or sit in the middle of the billing.
- We manage the order and install. Site surveys, construction updates, number porting, cutover day.
- We check the first bills. The quoted rate and the billed rate are not always the same thing. We reconcile them and chase any discrepancy.
Wondering what this costs you? Nothing — here's exactly how we get paid.
