                   WIRELESS TELECOM GROUP ANNOUNCES CLOSING OF
                   ACQUISITION OF WILLTEK COMMUNICATIONS GMBH

FOR IMMEDIATE RELEASE

PARSIPPANY, NJ - (BUSINESS WIRE) - July 1, 2005 - Wireless Telecom Group, Inc.
(AMEX Symbol: WTT), a global provider of electronic noise generation equipment
in the telecommunications field, announced today that it has completed the
acquisition of Willtek Communications GmbH, a leading German supplier of testing
solutions for emerging wireless services and cellular networks.

In accordance with the amended and restated stock purchase agreement among WTT,
Willtek, and each of Willtek's two shareholders, Investcorp Technology Ventures,
L.P. and Damany Holding GmbH, effective July 1, 2005, WTT purchased all of the
outstanding share capital of Willtek from the Willtek shareholders, in exchange
for 8,000,000 newly issued shares of WTT's common stock. Based on the $2.69
closing price of a share of WTT's common stock as reported on the American Stock
Exchange on June 30, 2005, the dollar value of the acquisition consideration is
approximately $21.5 million. At the closing of the acquisition, an aggregate of
7,000,000 shares were issued directly to the Willtek shareholders and 1,000,000
shares were deposited in escrow, for a one-year period following the closing
date, as collateral for the indemnification obligations of the Willtek
shareholders under the purchase agreement. Based on the number of shares of
WTT's common stock outstanding on June 30, 2005, the Willtek shareholders
presently own in the aggregate approximately 31.4% of WTT's outstanding common
stock, with Investcorp owning approximately 25.4% and Damany Holding owning
approximately 6.0%.

In connection with the closing of the acquisition, WTT also has guaranteed
payment of certain outstanding indebtedness of Willtek to Investcorp equal to
(euro)3.5 million (approximately $4.3 million), plus accrued but unpaid interest
at the rate of 8% per year through the closing date of the acquisition
(approximately (euro)607,000, or approximately $735,000).

Effective at the closing, Paul Genova resigned as a director of WTT, but will
continue to serve in his capacity as President and Chief Financial Officer of
WTT. At that time, two of Investcorp's designees, Savio W. Tung and Hazem
Ben-Gacem, were appointed to WTT's board. Mr. Tung was appointed Chairman of
the Board, replacing Karabet "Gary" Simonyan, who was appointed non-executive
Vice Chairman of the Board. In addition, at the closing, Cyrille Damany, the
Chief Executive Officer of Willtek and the sole shareholder of Damany Holding,
was appointed by WTT's board as the new Chief Executive Officer of WTT,
replacing Mr. Simonyan, who had served as interim Chief Executive Officer of
WTT since July 2004.

At the closing, WTT and the Willtek shareholders entered into a shareholders'
agreement, which provides that for so long as Investcorp's level of beneficial
ownership of WTT's common stock



continuously equals or exceeds certain percentage thresholds, at each annual or
special meeting of WTT's shareholders at which directors are to be elected,
Investcorp will be entitled to designate to WTT's nominating committee up to two
candidates for nomination for election to WTT's board. These rights will expire
at such time as Investcorp owns less than 5% of the issued and outstanding
shares of WTT's common stock, subject to a 20-day grace period. Furthermore, in
addition to restrictions on transfer imposed under U.S. federal and state
securities or "blue sky" laws, the shareholders' agreement provides for certain
restrictions on the transfer of the shares of WTT's common stock received by the
Willtek shareholders in the acquisition, as well as certain registration rights
with respect to such shares.

"We are pleased that the acquisition of Willtek is complete and look forward to
continuing the work that has already been accomplished between the two
companies," said Gary Simonyan, WTT's Vice Chairman. "The combination of
Willtek's operations with WTT's strengthens our competitive position, will add
significant incremental revenue and afford the combined company the ability to
offer a wider range of products to a larger, global customer base," Mr. Simonyan
added. "The acquisition is a significant event in the future direction of our
company and is a major step that is consistent with our strategic plan."

"I am very excited to join this dynamic organization, and I look forward to
leading the combined company's efforts to capitalize on a more diversified
product and technology portfolio, complementary customer relationships and
distribution channels on a global platform," said Cyrille Damany, WTT's newly
appointed Chief Executive Officer. "Our high quality technology and global
presence place the combined company at the forefront of the electronic noise
generation equipment and wireless communications testing market, and we are
eager to deliver a broader range of technology and products to our customers and
markets."

WTT's third quarter ending September 30, 2005 will reflect a full quarter of
operating results reflecting the acquisition of Willtek and its operations.
