Internet Service Alternatives in New Jersey
Since Cox has limited availability in New Jersey, residents should explore the established providers that actively serve the state. The New Jersey broadband market offers several competitive options across Newark, Jersey City, Paterson, and other communities.
Xfinity
Xfinity is one of the primary internet service providers in New Jersey, offering broadband coverage across major metropolitan areas including Newark and Jersey City. Depending on your address, you may have access to cable, fiber, or DSL technology. Plans typically range from basic tiers around $30-50 per month to gigabit speeds starting at $70-100 per month.
Verizon Fios
Verizon Fios also provides internet service throughout much of New Jersey. Coverage areas and available technologies vary by location, with some New Jersey neighborhoods having access to fiber optic service while others may be limited to cable or DSL connections. Contact Verizon Fios directly for address-specific availability.
Optimum
Optimum serves portions of New Jersey and may be available in select cities including Paterson, Elizabeth, and Trenton. Service options and pricing vary by market within the state.
T-Mobile Home Internet
T-Mobile Home Internet provides additional options for New Jersey residents, particularly in areas where traditional wired broadband options are limited. This can be especially relevant for rural New Jersey communities outside the Newark metropolitan area.
Understanding Cox Technology: DOCSIS 3.1 Cable
Even though Cox does not currently serve New Jersey, understanding the provider's technology helps New Jersey residents make informed comparisons. Cox's network is built on DOCSIS 3.1 cable technology, the latest generation of cable internet standards. This technology supports theoretical speeds up to 10 Gbps downstream and 1 Gbps upstream, far exceeding the speeds most providers actually offer to consumers.
The key advantage of DOCSIS 3.1 is efficiency. It uses OFDM (Orthogonal Frequency Division Multiplexing) to pack more data into the same cable bandwidth, resulting in faster speeds without requiring new physical infrastructure. For comparison, many cable providers in New Jersey still use older DOCSIS 3.0 technology, which supports maximum speeds of approximately 1 Gbps downstream but with less efficient spectrum usage.
Cox also deploys fiber-to-the-home (FTTH) in select new developments within its service territory. This true fiber technology delivers symmetric upload and download speeds, eliminating the upload speed limitation inherent in cable connections. If Cox were to expand into New Jersey, residents could potentially benefit from either DOCSIS 3.1 cable or FTTH fiber, depending on their neighborhood.
