Hearing Aid Compatibility
About Hearing Aid Compatibility
The move of the
wireless industry from analog to digital services has provided
some issues of concern for wireless users with hearing
disabilities. Digital technology can mean an enhanced wireless
experience, but some digital handset models can cause
interference for hearing aid users.
To ensure
accessibility for the deaf and hard of hearing to the use of
digital wireless devices, the Federal Communications Commission
("FCC") made updates to the Hearing Aid Compatibility ("HAC")
Act of 1988 to increase the number of HAC compliant wireless
devices on the market.
HAC Rating System
The American
National Standard Institute ("ANSI") has developed hearing aid
compatibility rating standard C63.19 to provide assistance to
hearing device users in finding the right digital wireless
device to purchase. Standard C63.19 provides a uniform method
for measuring the radio frequency ("RF") immunity and telecoil
coupling strength of hearing aids, as well as the RF emissions
and telecoil coupling strength of wireless devices. The
measurements are converted to a microphone ("M") rating and a
telecoil ("T") rating. Customers can use the ratings to predict
the compatibility of a particular digital wireless handset and a
hearing aid.
M-Ratings:
Wireless devices rated M3 or M4 meet FCC requirements and are
likely to generate less interference to hearing devices that
utilize a microphone for picking up sounds from the handset's
speaker. M4 is the higher of the two ratings.
T-Ratings:
Wireless
devices rated T3 or T4 meet FCC requirements and are likely to
be more usable with a hearing device's telecoil (a/k/a "T
Switch" or "Telephone Switch") than unrated wireless devices.
T4 is the higher of the two ratings. The advantage of a
telecoil is that it removes extraneous noise that would
otherwise be picked up by a microphone.
Hearing Device Immunity
Hearing devices
may also be measured for immunity to interference. To learn if
a digital wireless handset may interfere with a particular
hearing aid, the immunity rating of the hearing aid is added to
the rating of the digital handset. A sum of four would indicate
that the telephone is usable; a sum of five would indicate that
the telephone would provide normal use; and a sum of six or
greater would indicate that the telephone would provide
excellent performance with that hearing aid.
HAC Compatible Wireless Handsets
GCI/
Alaska Wireless has worked with our
vendors to improve the wireless experience for our customers
that use hearing aids. Per FCC guidelines, the handsets
featured below have been tested and rated for HAC.

Levels of Functionality
GCI/
Alaska Wireless is consistently
looking for ways to offer a full line up of hearing aid
compliant handsets. In doing so, the company strives to ensure
that its customers can choose from a diverse array of functions
and capabilities that are similar to the non-HAC handsets the
company sells, and that each compliant handset is reasonably
priced. The company does this by looking at available and
soon-to-be-available handsets first to determine whether they
are hearing aid compliant and what ANSI C3.19 standard they
meet. Once verified, the company also considers the types and
combinations of features it already offers and how the new
handset's features would complement the company's existing line
of products and whether its customers will continue to demand
those features in the future. The company also considers the
price of the handsets, taking into consideration the need
of customers at all levels of income, ranging from approximately
$100 per handset to more than $500 per handset.
GCI/Alaska Wireless currently
offers four different tiers of phones, each of which is based on
function, capability, and price. Tier I is comprised of HAC
compliant handsets with a basic set of features that customers
in Alaska expect of their mobile phones, including voice
dialing, polyphonic ringtones, a speaker phone, and predictive
text entry, a camera (select models), software for running small
programs like games, sending photos, etc., and Internet access
for a retail price beginning at $69.99 and higher. This tier is
comprised of the following handsets: Nokia 2720 and the Motorola
EM330. For Tier II, GCI/ Alaska Wireless offers phones that
have the functions of the first tier, plus additional features
including video players, higher resolution and color display,
and music players for a price ranging from $129.99 and higher.
Tier II is currently comprised of the following models: Alcatel
Tribe and the Samsung B2100. For Tier III, GCI/ Alaska Wireless
offers phones that have the functions of the first two tiers,
plus additional features including, but not limited to
touchscreen, high-resolution camera and E-Mail capabilities
(select models) for a retail price beginning at $189.99 and
higher. Tier III is currently comprised of the following
models: Motorola RAZR2 and the Nokia 5800. GCI/Alaska Wireless
Tier IV are smart phones that provide further functionality,
including PC-like capabilities, a full keyboard for typing text,
email accounts, etc., plus all the features of the first three
tiers, for a price that starts at $299.99 and higher. This tier
is currently comprised of the following Blackberry models: 8520
and 8900. On all handsets, discounted prices are available for
customers who sign up for a one or two year service term.
